Fig. 6 illustrates the concrete example of above-mentioned common storage 45.

Fig. 6 (a) represents the example data structure of common storage 45, and Fig. 6 (b) represents that data deposit example.

In Fig. 6 (a) example shown, common storage 45 deposit data 50 by port 51, equipment Title 52, address 53, data 54, these each data item of error message 55 are constituted.It addition, it In, the data item in addition to error message 55 can be roughly the same with prior art.Thus, carry out below Simple declaration.

Port 51 is the identification information etc. of above-mentioned COM1, substantially identifies as communication object Connect equipment 4 information.Equipment 52 is to set as the memorizer in the connection equipment 4 of communication object The identification information of standby (device memory).Address 53 is that the regulation in device memory shown in equipment 52 is deposited The address in storage area territory, deposits the data obtained from this memory area in data 54.

It addition, can regard as being equivalent to the upper of projects by port 51, device name 52 and address 53 State " distribution storage address ".That is, respectively record corresponding to projects shown in Fig. 6 (b).By picture data The above-mentioned distribution storage address of each project of the projects comprised in 22 grades is stored in port 51, sets Standby title 52 and address 53, thus generate each record shown in Fig. 6 (b).It addition, now, shape in advance Become linking between record and project.Thus, when carrying out the display renewal process etc. of Arbitrary Term purpose, With reference to the record corresponding with this project in common storage 45.

And, sometimes would indicate that by communication processing section 44 that there occurs that the information of particular error leaves in makes mistakes In information 55.That is, the data relevant with any project are obtained from above-mentioned distribution memory area, if should In the case of data acquisition failure, communication processing section 44 would indicate that the information (figure that there occurs particular error Show " makeing mistakes ") in the error message 55 of this record of this project that is stored in common storage 45.

As it has been described above, 2nd record being recorded as Fig. 6 (b) example shown relevant with a certain project In the case of, the address connecting the numbering 200 in the memory devices D of equipment 4-1 is that this project " is divided Join storage address ", it is illustrated that in example, the data of depositing that this " distribution storage address " is currently deposited are “1000”.But, error message 55 is in the case of " makeing mistakes ", and this numerical value is the most correct.

Such as, in the case of the 1st record of Fig. 6 (b) example shown, it is shown that connect equipment 4-1 Memory devices D in numbering 100 address in deposited data " 12345 ", but this deposits data It is not necessarily correct information.This is because deposited " to go out in the error message 55 of the 1st record Wrong ".

That is, communication processing section 44-1 tries from the numbering 100 of memory devices D connecting equipment 4-1 Address acquisition data, but due to communication mistake etc. cause data acquisition failure, therefore, the 1st The error message 55 of individual record has deposited " makeing mistakes " as shown in Figure.In this case, above-mentioned number It it not current data according to " 12345 ", it may be possible to legacy data.In the method, in this case, Such as show at the image recording corresponding project (above-mentioned chain such as can be utilized to fetch differentiation) with the 1st On, such as on one part overlapping specific markers (！) show.Thus, operator etc. identify Above-mentioned " 12345 " for just showing on such as picture are not the most correct numerical value.

Such as the process of following Fig. 8, project process portion 43 is such as each item of projects Mesh performs to process as follows termly: with reference to the respective record of common storage 45, obtain this data 54, And determine the display content of this item image based on these data 54 and be updated.This process itself can be with Prior art is roughly the same, but the project process portion 43 of this example is with further reference to error message 45, and base Process in error message.

That is, if error message 55 is " normally ", then project process portion 43 is only carried out and above-mentioned existing skill The process that art is identical.On the other hand, relevant with any project situation that error message 55 is " makeing mistakes " Under, project process portion 43 will make mistakes display view data 47 (specific markers (！)) overlap this project The display position of image i.e. overlapping the form on such as this item image and carry out showing (such as, as Fig. 4 example shown shows like that).But, this is an example, is not limited to this example.

Fig. 7 is the process chart of communication processing section 44.

Such as, in Fig. 5 example, each communication processing section 44-1,44-2 are the most periodically (with the fixed cycle) Perform the process of Fig. 7.

In the process example of Fig. 7, first, with reference to common storage 45, the company generating and itself serving as Connect equipment 4 relevant memorizer list 101 (step S1).Such as, communication processing section 44-1 carry out In the case of process, generate the memorizer list 101 relevant with connecting equipment 4-1.

Fig. 9 (b) illustrates the data structure example of this memorizer list 101.

In examples shown, memorizer list 101 by device name 71, address 72, data 73, go out Wrong these each data item of information 74 are constituted.Such as, the feelings of the example of above-mentioned communication processing section 44-1 Under condition, extract, from common storage 45, all records that port 51 is " WAY1 (circuit 1) ", will be each The device name 52 of extraction record, address 53, data 54, the information of error message 55 leave in State in device name 71, address 72, data 73, error message 74, generate and be connected equipment with above-mentioned Memorizer list 101 relevant for 4-1.It addition, data 73, error message 74 are not necessarily.Can Deposit expression and process the flag information whether terminated to replace them.

Afterwards, with reference to the memorizer list 101 generated, while repeating step S2～S7 Process, until step S7 be determined to be "No".

That is, untreated record (as processing object record) is read from memorizer list 101, based on this The content of record, generates memorizer reading order, sets to the connection itself served as via communication line 6 Standby 4 send this order (step S2).Afterwards, wait from the sound for this order connecting equipment 4 Answer (step S3).This order comprises the said equipment title 71, address 72 etc. and determines the letter accessing destination Breath (distribution storage address), the memory area that connection equipment 4 represents from this distribution storage address reads Data, the response carrying out replying these reading data processes.But, at digital independent for some reason And in the case of failure, reply memorizer reading and make mistakes.

Such as in the case of not responding to after the stipulated time from the moment sending mentioned order yet Situations such as (communication) makeing mistakes, or response contents is in the case of memorizer reads and makes mistakes etc., communication process Portion 44 is judged to there occurs particular error (step S4, yes), suitable at above-mentioned common storage 45 " makeing mistakes " (step S6) is deposited on the hurdle of the above-mentioned error message 55 in the record processing object record.

On the other hand, in the case of connection equipment 4 carries out normal response (step S4, no), this is rung Answer the above-mentioned reading data comprised to be stored in above-mentioned common storage 45 and be equivalent to process object record Record in above-mentioned data 54 hurdle in (step S5).It addition, now, the hurdle of error message 55 In deposited " makeing mistakes " in the case of, removed (or depositing " normally ").

Then, any process of above-mentioned steps S5, S6 is performed, afterwards, to memorizer list 101 In whether there remains untreated record and check, in the case of there remains, (step S7, yes) returns to Step S2, does not remains (step S7, no) in the case of having and terminates present treatment.

Fig. 8 is the process chart in project process portion 43.

As it has been described above, process the management in progress portion 42 based on project, periodically carry out the process of Fig. 8.

In the process example of Fig. 8, first, the initialization of project process portion 43 project implementation list 46 Process (step S11).Such as, the process end mark 67 of whole lists of bulleted list 46 is set to " untreated ".Afterwards, repeated execution of steps S12～the process of S19, until following step S19 becomes Till no.

That is, the arbitrarily record during mark 67 is the record of " untreated " in bulleted list 46 is set to place Reason object record, with reference to this process object record, obtains its (step such as device name 64, address 65 S12), utilize the respective record of they search common storages 45, and obtain its data (step S13). I.e., such as, its device name 52 is identical with the said equipment title 64 and address 65 with address 53 Record is exactly above-mentioned respective record.Then, using the data 54 of respective record and error message 55 as Memorizer information 102 carries out obtaining (step S13).

It addition, memorizer information 102 is made up of data 81 shown in Fig. 9 (c), error message 82, they It is data 54 and the error message 55 of above-mentioned acquisition.

Then, based on above-mentioned memorizer information 102, it is determined whether there occurs particular error (communication makes mistakes, Memorizer reads makes mistakes) (step S14).It is that " makeing mistakes " or " normally " enters according to error message 82 Row judges.Certainly, if error message 82 is " makeing mistakes ", then it is judged to there occurs particular error (step S14, yes), and transfer to step S16.On the other hand, if error message 82 is " normally ", then sentence It is set to and there is no particular error (step S14, no), and transfer to step S15.

In the case of there is no particular error (step S14, no), carry out display same as the prior art Process.That is, carry out using data 81 and information (image of project, the seat of above-mentioned process object record Mark, size etc.) general project drawing modification (such as on RAM13 launch) (step S15).

On the other hand, in the case of there is particular error (step S14, yes), carry out using above-mentioned process The information of object record and make mistakes display view data 47, paint according to project when makeing mistakes of this method System processes (step S16, S17).First, carry out decision make mistakes display view data 47 (specific markers (！ Deng)) display position coordinates process (step S16).

Itself there is various ways in the process of this step S16, substantially, based on coordinate 62 (=X, Y), Utilize the regulation deviant etc. that predetermines, determine specific markers (！) display position coordinates.Such as, In most cases, coordinate 62 is the coordinate in the upper left corner in item display area, therefore, by specific mark Note (！) display on the upper right corner of item display area time, such as use size 63 " width ", will (X+ width, Y) be set to specific markers (！) display position coordinates.

Then, carry out at the coordinate that above-mentioned steps S16 determines, draw (such as launching on RAM13) Above-mentioned specific markers (！) process (step S17).It addition, before, can enter in the same manner as step S15 Row project drawing modification, but also can not carry out this process.

It addition, as it has been described above, the displays such as the paint data on RAM13 are being shown by graphics controller 15 Show on device.Thus, in above-mentioned process example, on the right side of the image of the project that there occurs particular error Upper angle display specific markers (！).

So, determine the project that there occurs particular error, and corresponding to the figure of (overlapping or close) this project As show above-mentioned specific markers (！), thus operator etc. can identify at a glance and can not trust this project The content etc. of image.

After the process having performed above-mentioned steps S15 or step S16, S17, by bulleted list 46 The mark 67 processing object record is changed to " process terminates " (step S18).

Then, if bulleted list 46 there remains untreated record (step S19, yes), then return To step S12, if all process terminates (step S19, no), then terminate present treatment.

As mentioned above, according to the programable display 1 etc. of this example, it is associated with any project The acquisition of memory data when becoming the state that cannot obtain for some reason, determine this project also Display corresponding to this project carries out the display that makes mistakes, so that operator can determine exception at a glance Project.
