Description

Programable display and the storage medium for storing its program

Technical field

The present invention relates to programable displays etc..

Background technology

Programable display is generally connected with the various connection equipment such as PLC ontologies and temperature control device, and display carries out these companies The numerical value for connecing the status display of equipment is shown and the image of the projects such as lamp, or display sends out the switch of arbitrary instruction for user Etc. projects image.In addition, project is also referred to as screen component etc..In picture (the also referred to as operation display picture of programable display Face) in, usually show the image of multiple screen components (project).(the quilts such as the data for showing such operating display frame Referred to as picture data etc.) it is arbitrarily made by developer etc. in auxiliary device (not shown) in advance, being downloaded to from auxiliary device can Programming display.

In the picture data, for each project, including：Image (image of switch or the figure of lamp of the project Picture), display location coordinate, the number such as address (distribution reservoir address) of the predetermined region of external storage also described below According to.Sometimes also include certain program etc..

The projects (screen component) are for example formed arbitrarily element correspondingly with arbitrary connection equipment respectively, into The status display of row this composition element receives the instruction of this composition element being turned on and off.For example, in the temperature to temperature control device In the case that degree measured value carries out the project that numerical value is shown, current temperature is shown with numerical value at any time.Alternatively, indicating temperature control dress In the case of the project of that sets the open or close lamp of state, temperature control device is in an open state, and display lamp is lighted, to close shape Then display lamp extinguishes state.

In addition, in auxiliary device, lamp is logged in advance and lights image and lamp extinguishing image as item image, the picture Image is lighted comprising lamp and lamp extinguishes image in data for a lamp project.Certainly, this is not limited to the case where lamp, for other Project kind (such as switch etc.) is also identical.

The display control that the various projects are related to for example regularly implements defined processing by being directed to described projects To realize.Defined processing is for example, reading the predetermined region of the memory device (being assumed to be external storage) in connection equipment The storage data storage data of storage area (distribution), determined based on the storage data, display items purpose shows the place of content Reason (processing of display content refresh) etc..In addition, connection equipment updates the storage number of the predetermined region of the external storage at any time According to (such as updating the temperature measuring value at any time in the temperature control device).

In addition, the data read from the distribution storage area are temporarily stored within the memory device in programable display The predetermined region of (being assumed to be common storage) is determined based on the storage data, display items purpose shows content.

In the case of the examples, the storage data of the distribution storage area are read, the processing of common storage is stored in, It is for example regularly to be executed by the defined function part (it is assumed that being communication unit (not shown)) of programable display.It is described logical Letter portion is communicated such as with various connection equipment the PLC ontologies and temperature control device, is obtained described outer in connection equipment The storage data (the storage data of the distribution storage area) of the defined storage area of portion's reservoir, which is stored up There are the predetermined regions of the common storage.Also, carry out the various associated displays of project described in programable display The function part (assuming that being referred to as project display unit) of control carrys out item controlled and shows content by regular visit common storage.

In addition, previous, the picture data is usually made of multiple screens (picture).Each screen is substantially by more than one Screen component (project) constitute, and show special switching push button (screens switch switch) for switching to other screens. The identification id etc. of distribution switching target screen is switched to screens switch.

About such screens switch, such as the prior art recorded in known patent document 1.

The invention of patent document 1 is related to programable display, and its object is to the uses of not waste of resource, by processing load control It is made relatively low, reduces the time of screen switching.

Therefore, in the invention of patent document 1, screen switching button is pressed if detecting, will be used to determine composition and is somebody's turn to do The information registration of the data for the corresponding picture of screen switching button pressed is the reading data information of next picture, inspection When measuring the release of the screen switching button, the reading data information based on next picture, by what is read from control object Data replace with the reading data of the current picture shown on display picture.

Invention content

In programable display, in the case of carrying out screens switch, switch the display content of projects on target screen It must be able to the content of the storage data of the current distribution storage area of reflection.Conversely, if not obtaining switching target screen The storage data of the distribution storage area of projects on curtain, then can not substantially show switching target screen.

Opposite, for example, using the virtual switching mesh of arbitrary default image (such as whole projects are to close) display temporarily In the case of marking screen, since this has of course not reacted the display with the relevant present situation of projects, go wrong.Example Such as, in the case of the project for the lamp for opening or closing state for indicating the temperature control device, also to consider actually temperature control device Be in an open state but still display lamp extinguish image (as default image) example.Certainly, if by after a certain period of time, due to energy The distribution storage area storage data are obtained, therefore the screen display of normal condition can be carried out, but still have user to see Initial display is misinterpreted as temperature control device and is in off state this problem.

Therefore, in the past, after the storage data for obtaining the distribution storage area, switching target screen could be shown.This In, it is relatively time-consuming typically for the access process of distribution storage area.Show that switching target screen is relatively time-consuming as a result,.

Based on the above reasons, previous screens switch is relatively time consuming.

In the invention of the patent document 1, due to detecting that the stage for pressing screen switching button starts to be used for screen The processing of switching, therefore (detecting that the stage of release screen switching button starts for screens switch with its prior art Processing) it compares, screens switch becomes faster.

However, in the invention of documents 1, as a result, the start to process after operating screen switching button.In general, reading It takes the processing of the storage data of the distribution storage area relatively time-consuming, especially there is the feelings of multiple projects on switching target screen Become relatively time-consuming under condition.Therefore, the method for the patent document 1 still cannot fully realize the operation according to screen switching button Screens switch is carried out at once.

Problem of the invention is that providing a kind of programmable display that can carry out screens switch in programable display rapidly Device and its program etc..

The present invention is in programable display for example with following each unit.

First data acquisition unit, the projects of first data acquisition unit on the arbitrary screen to display are related The external storage of connection obtains data, by the acquirement data storage in the first interior magazine；

Picture display unit, storage data pair of the picture display unit based on first interior magazine are shown with described The associated picture of screen in showing is shown or is updated；

Second data acquisition unit, second data acquisition unit is from outside associated with projects on other screens Reservoir obtains data, by the acquirement data storage in the second interior magazine；And

Screens switch processing unit, the screens switch processing unit exist from the arbitrary screens switch to described other In the case of the switching instruction of screen, cutting to other screens is carried out using the storage data of second interior magazine It changes.

Specific implementation mode

In the following, the embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is the brief configuration figure of the system entirety of the programable display 1 comprising this example.

In addition, Fig. 1 shows structure be an example, but not limited to this.For example, must be not necessarily programable display 1 connects the structure of mapping editing device 5 via communication line 3.Programable display 1 and mapping editing device 5 also can be deposited individually ?.As long as programable display 1 carries out programable display according to this method stored picture data, using the picture data Picture is shown, can be any form.

Programable controller system shown in FIG. 1 has various connection equipment 4 and is connected via communication line 6 various Connect the programable display 1 of equipment 4.Further, programable display 1 connects mapping editing device via communication line 3 5.Programable display 1 includes multiple communication interfaces 2 (communication port), by connecting the communication line 3 of each communication interface 2, leading to Believe that circuit 6 is connected with various connection equipment 4 and mapping editing device 5.

Mapping editing device 5 is equivalent to the auxiliary device in above-mentioned background technology, and there is miscellaneous function, the miscellaneous function to make User can arbitrarily make for showing that aforesaid operations are shown (picture datas) such as the data of picture in programable display 1. In the past, prepare various item images in advance, user repeat to select desired item image, be disposed at it is desired Position on operation, carry out making for the picture data.

The picture data is as described above, is constituted using multiple screens, be arranged on each screen arbitrary one with On project.Also, as one of such project, there is the switch for switching to other screens.Phase is switched as with the switching Associated information includes the identification information (screen number) etc. of switching target screen certainly.In addition, this point itself with also can be with Previous is roughly the same.

But in the past, switching switch is operated, as " in order to obtain the processing of data necessary to screens switch ", though Above-mentioned " access to the distribution storage area of projects of switching target screen " has so been carried out, but has substantially been shielded in this method Distribution storage area is not accessed when curtain switching to complete (but not being 100%).Certainly, it after screens switch, needs to access at any time Storage area (accessing external storage) is distributed, the display content update processing is thus carried out.In detail as described below.

Mapping editing device 5 can also be regarded as to be assisted for the picture (picture data) to making programable display Auxiliary device an example.Therefore, the case where being also labeled as auxiliary device 5.

Above-mentioned picture data is downloaded to programable display 1.

Programable display 1 samely, by any one screen in the multiple screens for constituting picture data into Row display.In addition, on each screen, the associated project of the screen is shown, and also show the switch for switching the screen. In addition, during showing arbitrary screen, such as regularly, carry out the display content update.It is being shown for this purpose, accessing Screen on the associated distribution storage area of projects, obtain nearest data, the nearest data utilized to carry out The display of screen.

If also, during arbitrary screen display, the screens switch switch is operated, then switches to the switch pair The defined other screens answered are shown.At this moment, as described above, if cannot become on other screens of switching target The nearest data of projects can not then carry out the display of other screens.

For this purpose, it is previous, it is shown to switch to other screens, needs to access corresponding distribution storage area (accessing external storage), but this step (but not absolute, yet the case where access in need) is not needed in this method, therefore Screens switch can promptly be carried out.In detail as described below.

In addition, mapping editing device 5 is realized such as by general all-purpose computer (computer).Although as a result, not especially Diagram, but with the structure of general computer etc..That is, for example, with the storages such as arithmetic processors, reservoir, the hard disks such as CPU dress It sets, display units, the communication function portion such as operation portions, the display such as keyboard or mouse etc..

The application program as defined in the storage device in advance storage, the arithmetic processor execute the application program, from And realize the various functions of mapping editing device 5.In addition, the various functions of mapping editing device 5 are briefly illustrated It is functional, therefore no longer illustrate.

In addition, 1 its hardware configuration of programable display itself similarly can be general device.As a result, in the following, Simple illustration is carried out with reference to Fig. 2.

Fig. 2 is the hardware configuration example of the programable display 1 of this example.

Roughly the same with above-mentioned previous example, programable display 1, which has, carries out each screen based on above-mentioned picture data etc. The curtain display of (operating display frame) or the function of screens switch etc..But involved in screens switch from previous different portion Point, in detail as described below.

The programable display 1 of diagram has display operation control device 10, touch screen 18, display 19 and above-mentioned logical Believe interface 2 etc..

Display operation control device 10 is by CPU11, ROM12 (flash memory etc.), RAM13, communication controler 14, graphics controller 15, the compositions such as touch screen controller 16, they connect with bus 17.

CPU11 is to control the whole central processing unit (arithmetic processor) of display operation control device 10.CPU11 passes through The program (such as reality 21 etc. described below) for having previously been stored in ROM12 is executed, the various of programable display 1 are carried out Operation acts (processing).Although having done simple illustration to the processing, also will be described in more detail below.

In addition, the picture data (picture data 22 described below) etc. illustrated in the background technology is stored in ROM12.As described above, in this example, picture data 22 is made of the data of multiple (typically several) screens.Each screen The image of the projects such as the data of (operating display frame), such as switch, lamp by being arranged on the picture, display location The compositions such as the data such as coordinate, size and the distribution reservoir address.In addition, further, also setting up on every screen The screens switch switch.In addition, screens switch switch can also regard one kind of project as, it is to be accessed without external storage The project of type.

Here, above-mentioned external storage accesses, and refers to only associated with the project on the screen shown in the past The action that ground is implemented.However, in this method, not only for the screen shown, held also directed to switching target candidate screen Row said external reservoir accesses.Also, by defined storage area of the data storage of acquirement in programable display 1 (internal buffer etc.).

Using the processing of the CPU11, such as based on the picture data 22 or by accessing the external storage institute (description) is unfolded on such as RAM13 (or video-ram (not shown)) in the display object data of the data of acquirement etc..In detail As described below.Based on the description, graphics controller 15 shows above-mentioned operating display frame etc. on the display 19.

Touch screen is arranged on the liquid crystal display such as being constituted by liquid crystal display in display 19 in an overlapping manner 18.The arbitrary screen in multiple screens is shown on the display 19.As described above, it is shown respectively with specified position on each screen Item image.

In addition, communication controler 14 is via communication interface 2, it connect and sets with PLC ontologies (not shown) etc. or temperature control device etc. Standby 4 are communicated (data transmitting and receiving etc.) with mapping editing device 5.

For the testing result by the equal position for carrying out pressing operation (touch) on touch screen 18 of operator, via touch Screen controller 16 is acquired and parses in CPU11 etc..Such as the data of the display location coordinate or size based on projects Deng being parsed.For example, operator etc. touches the display location for switching image, then CPU11 etc. is resolved to this Switch is operated.

Fig. 3 indicates the software architecture diagram of above-mentioned this system.

In programable display 1, the various procedure, datas such as reality 21, picture data 22, signal procedure 23, such as It is stored in the ROM12 (flash memory etc.).By being read, being implemented by CPU11, with reference to these procedure, datas etc., carry out programmable aobvious Show the display control etc. of each operating display frame (each screen etc.) of device.

The image of the various projects such as the operating display frame shows by above-mentioned numerical value, lamp, switch, which is shown, to be constituted, projects Display content is for example to reflect what the regulation storage area (distribution storage area) of the external storage from each connection equipment 4 obtained The forms of data (obtain data) updates at any time.

That is, CPU11 is based on reality 21, picture data 22 and above-mentioned acquirement data, executes aforesaid operations and show picture Display control.At this moment, the display content of projects on the operating display frame (each screen component) reflects the acquirement The content of data (numerical value such as temperature are shown or lamp is lighted or extinguished).

As a result, in screens switch, to switching the associated various projects of target screen, it is also desirable to respectively to reflect this point The form of nearest (current or newest) storage data with storage area, starts to show.If for this purpose, previous operation display Switching switch, it is necessary first to access the corresponding each distribution storage area of projects on switching target screen, obtain data, therefore Consume processing time.However, can carry out reflecting the distribution storage area in this method, if even if not accessing distribution storage area The display of the nearest storage data in domain.In detail as described below.

In above-mentioned picture data 22, such as the picture data file 32 arbitrarily made in mapping editing device 5 side in advance, It is downloaded and is stored in programable display 1.That is, picture data 22 and picture data file 32 can also regard as it is substantially identical.Separately Outside, therefore to the two it does not distinguish especially, such as has and picture data file 32 is denoted as the case where picture data 22 illustrates.

In addition, above-mentioned signal procedure 23 also will for example have previously been stored in the signal procedure file 33 of 5 side of mapping editing device (its part) is downloaded and is stored in programable display 1.

The signal procedure 23 of programable display 1 is for via communication line 6 and the journey that connect equipment 4 and communicated Sequence.In general, each type etc. of connection equipment 4 has intrinsic communication protocol (communication procedure), according to the communication procedure, carry out Communication between programable display 1- connections equipment 4.Therefore, it is necessary to each type exploitation communication journeys for each connection equipment 4 Sequence 23.In addition, certainly, by executing signal procedure 23, realization and the communication process for connecting equipment 4 by CPU11 etc..

PLC ontologies etc. connect equipment 4, have various manufacturers or type, each manufacturer or type to have communication journey alone Sequence, depending on situation difference, with connection equipment 4 manufacturer or type correspondingly, can have a variety of signal procedures 23.

In addition, the communication between programable display 1- mapping editing devices 5 is for example edited by reality 21 and mapping Device 31 carries out (communication function, which is incorporated into, to be made in Graph editor 31).This content is not particularly relevant, therefore is not illustrated or illustrated.

Signal procedure 23 is usually in advance as 33 groups of (multiple the leading to the exploitation completion of each type of multiple signal procedure files Letter program) it is stored in mapping editing device 5 in HD (hard disk) (not shown).Later, if user, which utilizes, makees Graph editor 31 select simultaneously to specify arbitrary connection equipment 4, then editing device 5 of mapping is by the corresponding communication journey of connection equipment 4 with the selection Preface part 33 is transmitted to programable display 1, and is stored as the signal procedure 23.

Moreover, it is achieved that the access and picture to the distribution storage area such as show at the program of various processing, such as can be with Included in reality 21, picture data file 32 (picture data 22) can also reside in.No matter in the case which kind of, such as By executing such a program by CPU11, the various actions of programable display 1 can be realized.

Here, mapping editing device 5 make Graph editor 31 also have allow user to make desired operating display frame The miscellaneous function of (its picture data).As described, the various items storings that pre-production is completed are in mapping editing device 5 Hard disk etc. in.Using the miscellaneous function of making for the operating display frame made in Graph editor 31, guide look shows these various items Mesh, user select desired project, are arranged on desired position.The function itself with it is previous roughly the same.

In addition, mapping editing device 5 is, for example, computer etc., though it is not particularly illustrated, the knot with general conventional computer Structure (CPU, storage unit (hard disk, reservoir etc.), communication unit, operation portion (mouse etc.), display).It is advance by being executed by CPU It is stored in the application program of storage unit, realizes the processing function for making Graph editor 31.But as described above, make Graph editor 31 processing function itself is as in the past, therefore without more detailed description.

Fig. 4 is the functional block diagram of the programable display 1 of this example.

First data acquisition 41 of the programable display 1 of this example for example with diagram, picture display part 42, second count According to various functions portions such as acquisition unit 43, screens switch processing units 44.In addition, these various functions portions, by being held by the CPU11 Row is realized such as by the defined application program having previously been stored in the ROM12.

First data acquisition 41, from external storage associated with projects on the arbitrary screen shown Data are obtained, by the acquirement data storage at the first interior magazine (such as common storage 55 described below).

The storage of picture display part 42 (such as project processing unit 53 described below) based on first interior magazine Data are shown or are updated for picture associated with the screen shown.

In the state of showing the arbitrary screen, the second data acquisition 43 backstage from on other screens The associated external storage of projects of (such as on switching candidate screen) obtains data, by the acquirement data storage second Interior magazine (such as communication reservoir 57 described below).

" on backstage " refer to for example carrying out data for other screens (such as switching candidate screen) in addition, described Acquirement but the meaning of (at least in the display process of the arbitrary screen) without display, but it is not limited to the example.Separately Outside, in the following description, although not recording " backstage " one by one, such as the reservoir of switching candidate screen described below is pre-read It is also to be executed on " backstage " to take processing.

Screens switch processing unit 44 is having the case where being indicated from the arbitrary screen to the switching of other screens switchs Under, carry out the switching to other screens using the storage data of second interior magazine.

In addition, communication processing section 54 for example described below can for example be counted as being equivalent to first data acquisition 41 and second data acquisition 43, but it is not limited to the example.In addition, the processing function of screens switch processing unit 44, such as can be with It is counted as being realized by any of communication processing section 54 and project generating unit 51 described below (or two), but is not limited to The example.

In addition, the screens switch processing unit 44 for example by the storage data storage of second interior magazine (such as Replicate) in first interior magazine.As a result, in screens switch, even if without first data acquisition 41 Processing, also carry out associated with other screens picture using the picture display part 42 and show.That is, realizing to described other The switching of screen.

But when screens switch, have in projects on other screens not in second interior magazine into It went in the case of the project of data storage, then needs the processing of first data acquisition 41 for the project.The situation Under by carrying out the processing, can realize the switching to other screens.

In addition, the switching to other screens that the screens switch processing unit 44 is carried out, as long as it is above-mentioned that Sample is carried out using the storage data of the second interior magazine, is not limited to described " by the storage data of the second interior magazine Storage (such as replicate) is in first interior magazine " example.Such as another example, have second internal reservoir Device carries out the method etc. of reservoir management control as first interior magazine.

In addition, preferential execution is obtained by the data that first data acquisition 41 carries out or storage is handled, during idle time Between execute that the data carried out by second data acquisition 43 obtain or storage is handled.For this purpose, for example, the second data acquisition 43 when each processing executes, using the project of the part in projects on other screens as process object project.It changes Yan Zhi does not instead of disposably carry out data acquirement from external storage to whole projects on other screens, a little clicks through Row data obtain (such as an only one project).For this reason, it may be necessary to it is each execute processing when selected processing object item (from outer Portion's reservoir obtains the project of data).The method for selecting can be various methods, such as will never get data Project is preferentially used as process object project, is certainly not limited to the example.

Fig. 5 is the flow chart of the brief action example for the programable display 1 for indicating this example.

Fig. 6 is the flow chart of the detailed example of the processing for the step S2 for indicating Fig. 5.

In the example of Fig. 5, during showing arbitrary screen progress picture, repeat to operate as follows：This is being shown The existing display content that screen in showing is related to carries out refresh process (step S1), and executes and " carried out on backstage outer Portion's reservoir pre-read processing " (step S2).Also, any time during repeating step S1, S2 like this, if There is screens switch instruction (such as user operates the screens switch switch (not shown)), then the step S3 illustrated sentences It is yes to break, and is transferred to the later processing of step S4.

Processing to step S2, is also described in detail below by reference to Fig. 6, but briefly, for being possible to And then the screen (also referred to as switching candidate screen) shown after the screen shown, in advance from the switching candidate Storage data are read out in each " the distribution storage area " of the associated projects of screen.

Here, to simplify the explanation, it is assumed that only there are one project for each screen (still, except switching switch), it is assumed that described Switch there are one candidate screens.Also, for example, it is assumed that " the distribution reservoir of the project on the screen shown Address " is No. D100, and " the distribution reservoir address " of the project on the switching candidate screen is No. D200.

In the case of the example, No. D100 storage data are read in the step S1, the data based on the reading carry out The refresh process of existing display content.In addition, No. D200 storage data are read in the step S2, the reading data are temporary It is stored in defined storage area (internal buffer).

In addition, in the case that switching candidate screen is multiple, for other switching candidate screens, also from the item on the screen Purpose " distribution storage area " reads data, saves it in the internal buffer.

But substantially, since the processing that the screen shown is related to (reads data from distribution storage area And display update processing etc.) it is preferential, it is preferred that using the free time handled without these, cut described in progress Change the associated digital independent processing of candidate screen.

In addition, as a result, in the processing of step S2, it is difficult to the primary whole project phases for carrying out whole switching candidate screens Associated digital independent processing.Therefore, when executing the processing of step S2 every time, little by little digital independent is carried out (each time only Using the portion in the projects for switching candidate screen as reading object).Therefore, according to situation difference, in the case where carrying out When screens switch described in text operates, it is not limited to switch over the associated digital independent of whole projects on target screen.

If user carries out screens switch operation (step S3) on the screen shown as a result, to Each project on switching target screen carries out the judgement of step S4 described below respectively, and hereafter institute is executed according to judging result The processing of one of step S5, S6 stated.

That is, to each project on switching target screen, judge from relevant " distribution storage area " reading of the project Data whether there is in the internal buffer (step S4).Also, the data read (step in the case of internal buffer S4 is yes), then read the data (step S5) of the internal buffer.On the other hand, the data of reading are not in internal buffer In the case of (step S4 is no), then read data (step S6) from the project associated " distribution storage area ".

If also, being handled and being read using any of described step S5, S6 for whole projects on switching target screen Data are taken, then the data based on the reading switch over the picture of target screen and show (carry out screens switch) (step S7).

Also, return to step S1, the switching target screen become the new screen shown, described in progress The processing of step S1., such as screen (the new switching of the switching target to being likely to become the new screen shown then Target candidate screen), carry out the processing of the step S2.

In addition, it is assumed that for whole projects on switching target screen in the case where step S4 is judged as NO, carry out real Processing as in the past in matter, screens switch become time-consuming.However, in addition to such a special situation, screens switch The time of consuming is compared with the past to be shortened.Obvious, this is because the time that the processing of step S5 expends is than step S6 Processing expend time it is shorter.

In the following, the processing of the step S2 is described in detail with reference to Fig. 6.

As described above, data little by little are read (and temporarily from external storage when executing the processing of step S2 every time It is stored in internal buffer).When executing step S2 every time as a result, it is thus necessary to determine that become the minority of digital independent object at this moment (more than one) project.The main processing of the selected reading object reservoir is the processing of step S55 as shown in Figure 6.

In addition, the method for selecting of reading object reservoir can be various methods, illustrate herein as shown in Figure 6 Method be merely representative of an example.

In the example of Fig. 6, it is first determined whether being the relevant information (step S51) of picture.

Fig. 7 indicates an example of scene-related information.In addition, scene-related information is for example in 5 side of mapping editing device by opening Originator etc. is made while making arbitrary picture data 22, but can also download and store together with picture data 22 In programable display 1.

The transfer relationship that picture related information for example indicates to constitute between multiple screens of picture data 22 (switching source and is cut Change target).In Fig. 7, the title in each rectangle and rectangle indicates each screen and screen name.Also, it is straight between connection rectangle Line indicates the transfer relationship (switching source and switching target) of each screen.For example, cutting since " supervisory frame " screen of diagram It is only " production line 1 " screen to change target.Switching target since " line 1-2 " screen of diagram is " production line 1 " screen or " life Producing line 1-1 " screens.Switching target since " production line 1 " screen of diagram is " line 1-1 " screen, " line 1-2 " screen, " life 2 " screen of producing line or " supervisory frame " screen.

But scene-related information is not necessarily to have made.First determine whether that whether there is or not scene-related information (steps as a result, Rapid S51).Then, if there is scene-related information (being yes in step S51), will likely can become with reference to the scene-related information The screen (switching candidate screen) of the switching target of the screen shown is chosen to be the high screen (step S52) of priority. Also, it is shifted to step S53.In addition, also can " the high screen of selected priority " be known as " the advance reading object of external storage Screen ".

On the other hand, if without scene-related information (being no in step S51), do not make any handle and turn to step S53 It moves.

In addition, this is an example, it is not limited to the example.Such as it even if without the scene-related information, may be based on The data of gainer (the screens switch switch) on the screen shown, determine the high screen of the selected priority Curtain.That is, in screens switch switchs associated project data, include the identification information etc. of the screen as switching target.By This, the screen that the identification information can be also indicated, the screen high as the selected priority.

Additionally, it is possible to as arbitrary screen switching target screen have it is multiple in the case of, on the arbitrary screen Show multiple screens switch switches.In this case, these multiple screens switchs, which switch corresponding multiple screens, becomes described The high screen of selected priority.In addition, these multiple screens become to switch target candidate screen, switches to and wherein grasped with user The screens switch of work switchs corresponding screen.Accordingly, it is desirable to when the user operates, to whole switching mesh The associated whole projects of candidate screen are marked, an external storage pre-read processing was once performed.In this way, no matter specified more Which of a switching target candidate screen is not needed since the project whole to it is judged as YES in step s 4 External storage access is carried out in screens switch.

In addition, in step S53, judge whether internal buffer completes the storage of total data.This is judged as, such as Whole projects of whole switching target candidate screens judge whether that at least distributing storage area from it read a data, And it is already stored in internal buffer (whether completing data from whole reading object reservoirs to obtain).

Such as an example, in the selected processing of the pre-read reservoir of step S55, reach described " slow in inside Rush device complete total data storage " state before, be never obtain data reading object reservoir in carry out selected mould Formula (does not obtain data storage device mode of priority).If also, without not obtaining the reading object reservoir of data (in internal damping Device completes total data storage), then next become the storage data for internal buffer, from legacy data successively to newest number According to the pattern (the preferential renewal model of legacy data) being updated.

In addition, step S53 be in the case of, as described above, due to the use of person no matter select which screen as It is all yes to switch target step S4, therefore carries out external storage access completely without for screens switch.

The step S53 is set as described and does not obtain reservoir mode of priority before being judged as YES, the step S53 is judged as By pattern switching it is then the preferential renewal model (step S54) of the legacy data after being.Later, before carrying out screens switch During, keep the preferential renewal model of legacy data.If in addition, carrying out the screens switch of step S7, storage is not obtained described in return Storage mode of priority is then back to step S1.

After the processing for executing either one or two of described step S51~S54 or more, the pre-read reservoir of step S55 is executed Selected processing.

In the case that the processing of step S55 for described in for example, currently do not obtain reservoir mode of priority, data are never obtained Project (its distribute reservoir) in select preferential pre-read reservoir.It at this moment, can be by the institute in the project for not obtaining data The project that the project of the high screen of selected priority is selected as priority is stated, but is not limited to the example.In addition, step described below In the processing of rapid S56, data are read from selected pre-read reservoir.

On the other hand, currently for the preferential renewal model of the legacy data in the case of, in the storage data of internal buffer (it is distributed stores the middle project by corresponding to oldest data (such as being judged based on renewal time 75 described below) Device) it is chosen to be pre-read reservoir.

Can also be multiple (can also be pre- prerequisite in addition, in either case, pre-read reservoir is not limited to one Fixed regulation number).

It is the method for selecting of basic pre-read reservoir above, but not limited to this, it can also be for example in available free physics In the case of port, the preferential selected external storage (distribution reservoir) accessed using the free physical port.For example, hereafter In the example of described Fig. 8, there is a port with the connection equipment 4-1 connections of diagram, and with the end that connect equipment 4-2 connections Mouthful.In the example, using distribution reservoir access process associated with the screen shown, currently with connect It is the free physical port with the port of equipment 4-2 connections is connect in the case of equipment 4-1 communications.The feelings of the example as a result, Under condition, it can also be distributed the project that reservoir is the reservoir in connection equipment 4-2 and be chosen to be preferential pre-read reservoir.

Alternatively, the project to meeting rated condition, it also can be in the associated distribution storage of the screen shown In device access process digital independent (and storing to internal buffer) is carried out along band.

The project for meeting the rated condition refers to, such as preferably by the associated stored list described below of the project The data of P2 merge (addition) to the project of stored list 90 described below.One example of such a project exemplified hereinafter Son, but not limited to this.The identical memory device of memory device of access target associated with the screen shown The project to access.

It is continuous in distribution storage area (such as No. D100~No. D103) associated with the screen shown The project that accesses of storage area (in the example be No. D104 etc.).It in other words, e.g. can be by No. D100~No. D104 The project that equal merging access.

Also, data (step S56) are read from the pre-read reservoir selected by the step S55, by the reading Data are temporarily stored within internal buffer (step S57).

In addition, if it is of course possible to, also whole reading object reservoirs can be chosen to be pre-read storage in step S55 Storage.

In this method, when indicating to arbitrary screens switch, institute has been carried out to whole projects on the switching target screen In the case of the processing for stating step S56, S57, showing the switching target screen using the data of the internal buffer, (it is initial State).That is, when screens switch data (need not being communicated with equipment 4 is connect) need not be obtained from external storage.By This, can realize the screens switch of very short time.

In addition, the processing that with a portion of step S56, S57 only to the project on the switching target screen In the case of, the screens switch compared with the past that can also realize the short time.In addition, it is generally the case that switch as long as no completion The data of the associated whole projects of target screen obtain, then can not carry out screens switch.

Fig. 8 is the structure of the programable display 1 of this example, processing function figure.

CPU11 by execute be stored in for example described ROM12 established procedure (such as the reality 21, communication Program 23 etc.), to realize the interior various processing function portions indicated of the dotted line of such as Fig. 8.That is, realizing the project generating unit of diagram 51, the various processing function portions of project processing plan portion 52, project processing unit 53, communication processing section 54 (54-1,54-2 etc.) etc. Following processing functions.

In addition, for example, project generating unit 51, project processing plan portion 52 and project processing unit 53 are real by reality 21 It is existing.Communication processing section 54 is realized by reality 21, signal procedure 23.

Project generating unit 51 is based on described picture data 22 etc., generates bulleted list 56.This is for example to extract frame numbers out (further add processing described below and complete label 87) generated according to the form of 22 part.

Here, as described above, picture data 22 is made of data associated with multiple screens, the screen shown The associated data of curtain are substantially stored in bulleted list 56.Project generating unit 51 is opened in the switching of each operation display as a result, Guan Shi deletes the data of existing bulleted list 56 and common storage 55, generates new item corresponding with switching target screen Mesh list 56 and common storage 55 (still, at this moment do not have data in the data 64 of common storage 55, for example replicate later Communicate the data of reservoir 57).

In project generating unit 51, further, after the data for communicating reservoir 57 are copied to common storage 55 etc., The data of deleting communication reservoir 57, generate next switching target candidate the corresponding new communication reservoir 57 of screen (but It is, at this moment the no data in the data 74 of communication reservoir 57).But the processing can also be carried out by communication processing section 54.Separately Outside, described " next switching target candidate screen " refers to the screen that screens switch switch is corresponding in the switching target screen Curtain.

Project processing plan portion 52 is counted by the display update processing etc. of the projects executed by project processing unit 53 Draw management.That is, project processing plan portion 52 for example regularly recalls project processing unit 53, execute Figure 17's for example described below Processing (in other words, the processing of cycle execution Figure 17).

Storage data of the project processing unit 53 based on the bulleted list 56 and common storage 55 described below, to every A project, by its image include in specified position, and it is shown content be updated processing (such as switching open or close The numerical value etc. that image and update numerical value are shown) etc..

Project processing unit 53 describes (expansion) various images along with the processing on RAM13.As a result, by by figure This is described the data display over the display by controller 15, shows the display operation picture.This is described the data is handled by project Portion 53 is for example updated when executing the processing of Figure 17 described below every time at any time.In addition, the processing of project processing unit 53 Itself, substantially also can with it is previous roughly the same.

Communication processing section 54 includes communication processing section 54-1,54-2 corresponding with each connection equipment 4 (4-1,4-2).Communication Processing unit 54 for example carries out the update processing of the storage data of common storage 55.

I.e., it is illustrated that communication processing section 54-1 uses and the connection corresponding communication port WAY1 of equipment 4-1, via communication line Road 6 carries out, with the communication for connecting equipment 4-1, obtaining the storage number of the predetermined region (distribution storage area) of its external storage According to.I.e. from the project on the screen shown, obtain and the item assigned by the external storage connecting in equipment 4-1 The associated data of mesh.Data cover is obtained to be stored in the predetermined region of common storage 55.

Likewise, the communication processing section 54-2 uses of diagram communication port WAY2 corresponding with connection equipment 4-2, via logical Believe circuit 6, carries out, with the communication for connecting equipment 4-2, obtaining the storage of the predetermined region (distribution storage area) of its external storage Deposit data.I.e. from the project on the screen shown, obtain with assigned by the external storage connecting in equipment 4-2 The associated data of project.Data cover is obtained to be stored in the predetermined region of common storage 55.

But the update processing of storage data of the common storage 55 itself is roughly the same with existing processing.This Each communication processing section 54 of example not only carries out the existing processing and also executes new processing described below.

That is, each communication processing section 54 also executes the processing of the storage data of more new traffic reservoir 57.Here, it is stored up in communication Storage 57 stores the associated data of the switching candidate screen.As described above, for example, on the screen shown It is the switching candidate screen that screens switch, which switchs corresponding screen,.

Also, substantially in the same manner with the screen shown, communication processing section 54 is also to the switching candidate screen Data acquirement is carried out from corresponding external storage.But obtain data and be not stored in common storage 55, and be stored in described In internal buffer.Communication reservoir 57 is equivalent to the internal buffer.That is, communication processing section 54 is read on switching candidate screen Projects distribution storage area storage data, be stored in communication reservoir 57.Certainly, each communication processing section 54-1,54- 2 only carry out digital independent from the connection equipment 4 being each responsible for respectively.

The new processing is referred to as the update processing of the storage data of communication reservoir 57.One example of the processing is The processing of described Fig. 6.

In addition, from the foregoing it can be that communication reservoir 57 data structure (each data items), substantially with shared storage Storage 55 is roughly the same.Common storage 55 is with the data structure for communicating reservoir 57 as shown in figure 9, will say below It is bright.

Also, when operating screens switch switch by user at the time of arbitrary, communication processing section 54 (or project generates Portion 51 etc.) the storage data for communicating reservoir 57 are replicated into (covering) to common storage 55.External storage need not be accessed as a result, Storage (distribution storage area), can show switching target screen.

Here, the concrete example of the bulleted list 56, common storage 55, communication reservoir 57 is illustrated.

Fig. 9 (a) indicates that the data structure example of common storage 55, Fig. 9 (b) indicate the data storage of common storage 55 Example.

In example illustrated, common storage 55 is by port 61, device name 62, address 63, data 64, error message 65 It is constituted etc. each data items.

Port 61 is the identification information etc. of the communication port, is that the connection equipment 4 substantially to communication counterpart is known Other information.Device 62 is the identification information of the memory device (external storage) in the connection equipment 4 of communication counterpart.Address 63 It is the address of storage area specified in the external storage represented by device 62, the data storage obtained from the storage area In data 64.

In addition, device name 62 and address 63 can also regard " the distribution reservoir address " for being equivalent to projects as.It Be for example to the device name 84 of bulleted list 56 described below, address 85 replicated obtained by content.In addition, port 61 are alternatively by judging corresponding connection equipment 4 based on such as device name 62, the communication port number judged.Or It can also include communication port identification information etc. that person, which includes not only memory device title in the device name 84 being described below,.

In addition, with connecting equipment 4 and communication mistake occur, the error message (" mistake " shown in Fig. 9 (b) Deng) be stored in error message 65.

Fig. 9 (c) indicates that the data structure example of communication reservoir 57, Fig. 9 (d) indicate the data storage of communication reservoir 57 Example.

Reservoir 57 is communicated by each data items such as port 71, device name 72, address 73, data 74, renewal times 75 It constitutes.Wherein, each data items such as port 71, device name 72, address 73, data 74 also can be with the common storage 55 Each data items 61,62,63,64 are roughly the same.When the storage data of data 74 are updated every time, time at this moment (such as open Elapsed time etc. after dynamic) it is stored in renewal time 75.In the update processing of data 74 described below, such as by whole records Middle renewal time 75 is minimum (in other words, from elapsed time longest after last time update；It is oldest) record as update processing pair As record.

For example, in example shown in Fig. 9 (d), beginning record (record of renewal time 75=' 5000 ') is as at update Manage object record.Certainly, it is not limited to the example, such as update process object record or multiple.That is, being not only oldest note Record can also be recorded using the old record of the second old record or third as update process object.

In addition, indicating the data structure example of bulleted list 56 in Figure 10 (a).

The bulleted list 56 of example illustrated by item types 81, coordinate 82, size 83, device name 84, address 85, " data of each item types " 86 and processing are completed each data items such as label 67 and are constituted.

As described above, the associated provisioning information of projects on screen shown is stored in bulleted list 56.Substantially, corresponding projects of each record.When switching screen every time as a result, bulleted list 56 is updated.That is, screens switch When, the storage data of bulleted list 56 this moment are deleted, and are generated based on picture data 22, are stored new data.Certainly, newly Data are the associated data of projects switched on target screen.

The project kind that the type (switch, lamp, numerical value are shown) for indicating the project is stored in item types 81 identifies letter Breath.In addition, also may further be " screens switch switch " etc. as project kind.

In addition, the external storage that device name 84 and address 85 are projects accesses associated information, quite In the distribution reservoir address.That is, the storage area that address 85 indicates in external storage represented by device name 84 is For the region (the distribution storage area) assigned by the project.The storage data of the distribution storage area indicate the project phase It is associated monitoring, control object current state.If such as item types 81 are lamp, then it represents that the label of lamp lighted, extinguished Data etc. are the storage data.The storage data are updated at any time in 4 side of connection equipment.In addition, distribution storage area Storage data are periodically read, and are temporarily stored in the data 64 of the corresponding record of the common storage 55.

In " data of each item types " 86, it (is, for example, the item of lamp to store such as the associated image of the project Mesh is then that lamp lights image and lamp extinguishes image, or the project then closing for opening image and switch to switch if switch The various item images such as image).

Storage indicates that the item image is aobvious on the operating display frame (screen) in coordinate 82 and size 83 Show the information of position and size.

Here, the screens switch switch is also one kind of the project, therefore screens switch switchs associated information It also is stored in bulleted list 56.

Figure 10 (b) indicates the data storage example that screens switch switchs in bulleted list 56.

Firstly, since screens switch switch is one kind of switch, therefore " switch " is stored in item types 81.But It is not limited to the example, in the case that " screens switch switch " is defined as project kind, " screen is cut for storage in item types 81 Change switch ".The example is used in this explanation.

In addition, since external storage access is unwanted project, the storage number of device name 84 and address 85 According to for "None".

Also, in " data of each item types " 86, the item image is not only stored, the screens switch is also stored and opens Close the identification id (picture number etc.) of corresponding switching target screen.

Figure 12 indicate screens switch before and after projects the case where.

In example illustrated, indicate from the screens switch of No. 1 picture to the screen of No. 2 pictures.That is, showing No. 1 If operating the screens switch switch (" switching to No. 2 picture SW " in diagram) on the screen in the state of the screen of picture, Then it is switched to the screen of No. 2 pictures.In addition, though it is not shown, but there is also screens switch switches on the screen of No. 2 pictures.

Five rectangles on each screen of diagram indicate that the project on the screen is shown, but do not indicate that in actual display Hold.That is, the distribution reservoir address of textual representation projects in each rectangle.As shown, by switching screen, the item of display Mesh changes, therefore distributes reservoir address and also change.

That is, for example, in the state of showing the screen of No. 1 picture, each point from diagram of the communication processing section 54 It reads storage data respectively with reservoir ' D100 ', ' D200 ', ' D300 ', ' X0 ', ' Y0 ', is stored in common storage 55. Also, storage data of the project processing unit 53 based on shared storage unit 55 carry out the display of the screen of No. 1 picture.Itself with It is past roughly the same, but the communication processing section 54 in this method also carries out each distribution from the associated diagram of the screen of No. 2 pictures Reservoir ' D1100 ', ' D1200 ', ' D1300 ', ' M0 ', ' M1 ' read storage data, storage to communication reservoir 57 respectively Processing.In this method further, communication processing section 54 etc. to " the switching to No. 2 picture SW " the case where having carried out operation Under also execute the storage data for communicating reservoir 57 be copied to the processing etc. of common storage 55.

In the following, the processing to the communication processing section 54, project processing unit 53 is further described.

Figure 13, Figure 14, Figure 15, Figure 16 are (1/4) of the process chart of communication processing section 54, (2/4), (3/4), (4/ 4)。

In the following, referring to Fig.1 3, Figure 14, Figure 15, Figure 16 (being denoted as in the case of not distinguishing especially " Figure 13 etc. ") be to communication Processing unit 54 illustrates.

Such as each communication processing section 54-1,54-2 recycle execution Figure 13 etc. (with the fixed cycle) respectively in the example of Fig. 8 Processing.

In the processing example of Figure 13 etc., first, with reference to common storage 55, it is associated to generate oneself responsible connection equipment 4 Stored list 90 (step S11).For example, in the case where being handled using communication processing section 54-1, from common storage 55 generate the associated stored lists of connection equipment 4-1 90.

Figure 11 (a) indicates the data structure example of the stored list 90.

In example illustrated, stored list 90 is by each data such as device name 91, address 92, data 93, error messages 94 Project is constituted.In addition, error message 94 is not essential.

Such as in the communication processing section 54-1, the record of " WAY1 " is completely drawn out by port 61 from common storage 55. Also, this it is each extraction record device name 62, address 63, data 64 information be stored (duplication) in the device name 91, in address 92, data 93.The associated stored lists of the connection equipment 4-1 90 are generated as a result,.In addition, data 93 are not It is necessary.

Later, the place between step S12~S23 of diagram is repeated on one side with reference to the stored list 90 generated on one side Reason, until step 23 is judged as NO.

That is, taking out untreated record (being recorded as process object) from stored list 90, recorded based on the process object Content generate reservoir and read instruction, be sent to oneself responsible connection equipment 4 (step S16) via communication line 6.And And connection equipment 4 is waited for read the response (step S17) instructed for the reservoir.But carry out the processing of step S16 Before, status check is carried out, judges whether carrying out screens switch (step S12).

For example, the corresponding defined storage area of the screens switch switch has been preset, in the defined storage area Storing marking in domain.Also, when each operation display switching switch, label becomes opening.In addition, in the defined storage area The label is not only stored in domain, can also store the identification id (picture number etc.) of switching target screen.

In addition, project generating unit 51 always monitors the label, when label becomes to open every time, the bulleted list 56 is executed Generation processing.That is, deleting the current data of bulleted list 56, the items of the switching target screen are extracted out from picture data 22 Purpose information is stored in bulleted list 56.

Such as an example, the judgement processing that the step S12 is carried out with reference to the label, if labeled as opening It is judged as in screens switch (step S12 is yes), is transferred to step S13.In step S13 retrieval communication reservoirs 57, example is detected Corresponding record as described below checks whether and completes whether data storage (stores any data, be in data 74 to the record It is no that there are pre-reading datas) (step S14).

Here, as an example, the judgement of step S14 described in whole project implementations to the switching target screen. But in the case that the switching candidate screen is multiple, it is associated to store these switching candidate screens in communication reservoir 57 Multiple projects data.Thus, it is desirable to judge the project of the switching target screen from these multiple projects.For this purpose, example As an example, also the described of the corresponding screen of record (project) can be also stored in each record of communication reservoir 57 Identification id (picture number etc.), but it is not limited to the example.

No matter which kind of situation, to whole records corresponding to the project of switching target screen described in communication reservoir 57 (corresponding record) carries out the judgement of the step S14.Also, in corresponding record, stored up for being judged as completing the data Its data is copied to common storage 55 (step S15) by all records (replicating object record) for depositing (step S14 is yes). For example, each data items 71~73 for replicating object record and data 74 to be copied to the data items of common storage 55 61~63 and data 64.In addition, at this moment, for the record that data do not store, which may be duplicated for sharing In the data items 61~63 of reservoir 55.

In addition, before executing duplication to the common storage 55, it also can be whole by the data with existing of common storage 55 It deletes.

On the other hand, in projects of the switching target screen, project (data that the step S14 is judged as NO Obtain object item) there are one in the case of above, object item is obtained to each data, utilizes the processing of step S16, S17 External storage access is carried out, data are obtained, is executed using the processing of step S19 and the corresponding data storage that obtains is being shared into storage Processing in the data 64 of the corresponding record of device 55.In addition, external storage access target in this case be not based on it is described The stored list 90 made in step S11, but the device name 72 based on the communication reservoir 57 and address 73, but it is unlimited In the example.

It certainly, need not be into whole projects on switching target screen in the case where the step S14 is judged as YES The processing of row step S16, S17 etc..Certainly, the case where when this is screens switch, regularly to showing after switching Screen on projects execute the processing of step S16, S17 etc..

It, also can be into being about to described mark the processing that is set off in addition, before the processing of the step S13 executes. Further, can also make the total data of the stored list 90 be set as the state that processing is completed (thus to sentence step S23 pressures It is no to break).

In addition, the processing in the case of being judged as YES of the step S12 (is specifically the place of step S13, S14, S15 Reason), it is not limited to an above-mentioned example.For example, project generating unit 51 regenerates project based on opening label as described above List 56, but also can also regenerate common storage 55 to accompanying this.In the case of the example, such as the step S15 Processing when, in the case that the data items 61~63 of common storage 55 have been the corresponding content of switching target screen, only Data 74, which are copied to data 64, (need not replicate other data items).

More than, to there is the processing of the case where screens switch instruction to be illustrated.

On the other hand, in the case of being indicated without screens switch (step S12 is no), based on being made in the step S11 Stored list 90 processing between step S16-S23 is repeated until step to projects on the screen that is showing Until rapid S23 is no.

For the step S16, comprising the device name by the stored list 90 in the reservoir reads instruction The information of distribution storage address determined by 91 and address 92 etc..Connect the storage area that equipment 4 is indicated from distribution storage address Data are read in domain, carry out the response processing for replying the reading data.But also have the case where generating communication mistake, in this case " mistake ", is stored in (step in the error message 65 of the corresponding record of common storage 55 by (step S18 is yes) S22), it is transferred to step S23.

(the step in the case where no communication mistake (step S18 is no) has the normal response from connection equipment 4 S17), the reading data cover which includes is stored in the common storage 55 and is equivalent to processing by communication processing section 54 In one column of the data 64 in the record of object record (step S19).But it is equivalent to the note of the process object record Record (corresponding record) is not only present in common storage 55, also there is the case where being present in communication reservoir 57.That is, the processing pair The case where as being temporarily appended to stored list 90 in recording the processing for the step S31 being described below.

Such as in the case that the step S19 is performed normally, it is judged as not synthesizing that (step S20 is in step S20 It is no), it is transferred to step S23.On the other hand, in the case that the corresponding record is not present in the common storage 55, judge For " synthesis " (step S20 is yes), by the data storage that the step S17 is obtained and is read in communicating reservoir 57 In the data 74 of corresponding record (step S21).Also, it is shifted to step S23.

In addition, the processing of step S11 carries out at the very start when executing the processing such as Figure 13 every time in the figure, but it is not limited to The example.Because as long as the content of common storage 55 is constant (as long as that is, without screens switch), there is no need to make one by one Stored list 90.Certainly, in the case of carrying out screens switch, the content alteration of common storage 55 is that switching target screen corresponds to Content, it is therefore desirable to execute the processing of step S11.It means that such as step S12 is in the case of being, it also can be therewith After the corresponding various processing execute, for example, step S23 be it is no after etc., execute the processing of step S11 at once.

(step S23 is yes) return to step S12 in the case of also having untreated record in stored list 90, if not having Untreated record (step S23 is no), in the past, then processing terminated, but in present treatment, if the available free time, (step S24 was It is), then it executes the switching associated following data pre-heads of candidate screen and takes processing.

First, at the beginning, it is based on communication reservoir 57 and generates stored list P2 (step S26).Due to data structure itself It is identical as the stored list 90, thus by stored list P2 be set as using each data items 91~94 shown in Figure 11 (a) into The list of row explanation.

In this example, such as when carrying out present treatment every time, any one record in each record of stored list P2 is made For process object, executes data pre-head and take processing.That is, will for example not obtain the project of data preferentially as process object.That is, In each record of stored list P2 there are the record for not having to store data in data 93 in the case of (step S27 is yes), by it It is recorded as process object.Do not obtain data record have it is multiple in the case of, such as from upper (press login sequence) successively by its (step S28) is recorded as process object.

On the other hand, whole records of stored list P2 all complete (step S27 is no) in the case that data obtain, will most The record of old data is as process object record (step S29).That is, for example differentiating in each record of communication reservoir 57 more The record of the data value minimum of new time 75, the record that this is recorded to corresponding stored list P2 are recorded as process object.

In addition, in stored list P2, the data items (renewal time (not shown) for replicating renewal time 75 may also set up 95).In this case, in the processing of step S29, the data value minimum of renewal time 95 described in each record of stored list P2 Record is recorded as process object.

Also, the process object is recorded, substantially in the same manner with step S16, S17, reservoir reading is carried out and refers to The generation of order is sent, and response receives (step S32, S33).Also, it is normally connect without communication mistake (step S34 is no) In the case of receiving response, by (step S35) in the data 74 for receiving the corresponding record that data cover is stored in communication reservoir 57. Then, at this moment, update the renewal time 75 (such as storage start after until current time elapsed time).In addition, hair In the case of raw communication mistake (step S34 is yes), it is set as untreated (step S36).

Alternatively, after process object record is determined in the step S28 or S29, it also can be to the process object be recorded Associated external storage access process external storage access process associated with screen is being shown is synthesized Whether relatively good judged (step S30).The concrete example of the judgment method had described, therefore omitted herein.

Be determined as (step S30 is yes) in the case of synthesis ratio is preferable, also can stored list 90 will process object record Temporarily synthesis (additional storage) (step S31).Process object record is deleted from stored list P2 in this case.

Project for the processing for performing the step S31 is stored up with from the associated distribution of the screen that is showing Deposit the pre-read processing for handling progress data together that region obtains data.And using the processing of the step S21, by pre-reading The data cover that processing obtains is taken to be stored in the data 74 of the corresponding record of communication reservoir 57.

In addition, Figure 13~Figure 16 indicates the basic method for selecting pair in the method for selecting illustrated in the step S55 of described Fig. 6 The processing example answered, but it is not limited to the example.Also other method for selecting that step S55 illustrates can be attached to, the concrete example is omitted.

Figure 17 is the process chart of project processing unit 53.

As described above, the processing of Figure 17 recycles execution based on the management in project processing plan portion 52.

In the processing example of Figure 17, the initialization process (step S41) of bulleted list 56 is first carried out in project processing unit 53. It is set as " untreated " that is, label 87 for example is completed in the processing of bulleted list 56 all recorded.Later, step is repeated The processing of S42~S47 is no until step S47 described below.

That is, label 87 in bulleted list 56 is remembered for any one record in the record of " untreated " as process object Record, (step S42) such as its device name 84, addresses 85 is obtained with reference to the process object record, is shared using these information retrievals The corresponding record of reservoir 55 obtains its data (step S43).That is, such as device name 62 and address 63 and the device The identical record of part title 84 and address 85 is the corresponding record.Also, obtain the data 64 and mistake of corresponding record Information 65 is as storage information 100 (step S43).

In addition, storage information 100 data 101, error message 102 shown in Figure 11 (b) are constituted, they are described take The data 64 obtained and error message 65.

If also, error message 102 is not " mistake " (step S44 is no), uses data 101 and the process object The information (item image, coordinate, size etc.) of record carries out common project drawing processing (such as being unfolded on RAM13) (step Rapid S45).Also, label 87 is completed into the processing of the process object record and is set as label opening (processing is completed) (step S46)。

On the other hand, error message 102 is not execute the step S45's in the case of " mistake " (step S44 is yes) Processing, but directly execute the processing of the step S46.

Also, (step S47 is yes), return to step S42 in the case of also untreated record.If being held to all records Processing (step S47 is no) is gone, present treatment terminates.

The processing of the project processing unit 53 itself, also can with it is previous roughly the same.In addition, it is previous, in step S43 In the case of not having data 64, step S44 is judged as YES, therefore is described without project.For this purpose, for example just having switched in screen In the case of afterwards in equal common storages 55 there are no any data storage, data are obtained from distribution storage area, are stored in altogether Before being completed with the processing of reservoir 55, project description can not be carried out.That is, the processing can not switch over target before completing The display of screen consumes the time of screens switch.Previous this problem can be eliminated in this method.

Figure 18 is the example for the processing time for indicating each processing unit.

Project processing plan portion 52 is as described above, cyclically (the project processing time of the current picture of diagram；Display follows Ring) start project processing unit 53 execute such as Figure 17 shown in handle.

Each communication processing section 54 for example substantially can execute Figure 17's in project processing unit 53 at the time of arbitrary It is arrived after processing in the period before then executing the processing of Figure 17, has executed and shown that the associated data of screen take It must handle (next external storage access process).It is compared with the past, since the processing of each communication processing section 54 is most It is configured to have and executes surplus, therefore it is higher to generate the possibility of free time as illustrated.

Like this, for communication processing section 54, in each display cycle, defined communication process is generated (to showing Each project on the screen shown obtains it and distributes the storage data of storage area, is stored in the processing of common storage 55) Execution time and free time.As a result, in this method, using the free time, executes the data pre-head and take processing.

As described above, according to the programable display of this example 1, the screen that can rapidly carry out in programable display is cut It changes.
