Description

  The present invention relates to a programmable display and the like.

  In general, a programmable display is connected to various connected devices such as a PLC main body and a temperature control device, and items such as numerical displays and lamps for displaying the status of these connected devices, and for users to give arbitrary instructions. Displays an image of items such as switches. An item is also called a screen component or the like. Usually, images of a plurality of screen components (items) are displayed on the screen of the programmable display (referred to as an operation display screen). Data or the like for displaying such an operation display screen (referred to as screen data or the like) is arbitrarily created in advance by a developer or the like in a support device or the like and downloaded from the support device to a programmable display.

  The screen data includes, for each item, data such as an image of the item (switch image or lamp image), display position coordinates, and an address (assigned memory address) of a predetermined area of the external memory described later. It is. In addition, some programs may be included. The support device has a function of performing various types of support for allowing the user to arbitrarily create the screen data, for example. This is a well-known existing technique and will not be described here.

  Each of the items (screen parts) is, for example, a status display of the component corresponding to an arbitrary component of an arbitrary connected device, or receiving an ON / OFF instruction for the component. is there. For example, in the case of an item that displays the temperature measurement value of the temperature control device as a numerical value, the current temperature is displayed as a numerical value as needed. Or if it is the item of the lamp | ramp which shows the ON / OFF state of a temperature control apparatus, lamp lighting will be displayed if a temperature control apparatus is an ON state, and lamp OFF will be displayed if it is an OFF state.

  In the support device, a lamp-on image and a lamp-off image are registered in advance as item images, and the screen data includes a lamp-on image and a lamp-off image for one lamp item. Of course, this is not limited to the case of lamps, and the same applies to other item types (for example, switches).

  The display control related to the various items is realized, for example, by periodically executing a predetermined process for each item. The predetermined process is, for example, data stored in a predetermined storage area of a predetermined memory device (referred to as an external memory device) in a predetermined connected device related to the item (in the predetermined allocation memory area indicated by the allocation memory address). Stored data). Furthermore, a process for determining / displaying the display content of an item based on the stored data (display content refresh process) or the like. Note that the process of reading the data stored in the predetermined allocation memory area) is generally a process of accessing the external memory device, and therefore may be referred to as an external memory access process.

The connected device updates the stored data in a predetermined area of the external memory device as needed (for example, the temperature measurement value is updated as needed in the temperature control device).
Here, the support apparatus also has a function of allowing the user to set an arbitrary allocated memory address for each item. As described above, the screen data also includes the set allocated memory address. The screen data is downloaded from the support device to the programmable display device and stored. During operation, the allocated memory area is accessed based on the allocated memory address corresponding to each item.

  However, since the assigned memory address is set by a human as described above, there is always a possibility that a setting error will occur. When a setting error is detected after the screen data is downloaded and stored in the programmable display (during operation, etc.), conventionally, the user has performed an operation of correcting / changing the allocated memory address on the support device side. Of course, after the modification / change operation, the screen data including the changed allocated memory address is transferred to the programmable display device and newly stored.

Here, the prior art described in Patent Document 1 is known.
The invention of Patent Document 1 relates to a function for setting / changing an address (the allocated memory address) related to each component (corresponding to the item) in the editor device (corresponding to the support device), and the address can be easily changed. The editor device is realized.
JP 2010-108220 A

  As described above, in the prior art, even when the screen data (the allocated memory address) already stored on the programmable display side is corrected / changed, the correction / change operation needs to be performed on the support device side. For this reason, it becomes very troublesome especially when the programmable display and the support device are set at locations separated from each other. In addition, a setting error may occur.

  An object of the present invention is to enable modification / change of screen data (the assigned memory address, etc.) already stored on the programmable display side on the programmable display side, thereby reducing the modification / change work load. It is to provide a programmable display or the like.

The programmable display of the present invention is a programmable display connected to one or more connected devices, and has the following configurations.
Item information storage means for storing access information indicating an access destination corresponding to each item on the display screen;
Item display means for acquiring data from the access destination based on the access information of the item information storage means and displaying the item using the acquired data;
Access information changing means for arbitrarily changing the access information related to the item to be changed arbitrarily;

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram of the entire system including the programmable display 1 of this example.
The configuration shown in FIG. 1 is an example, and the present invention is not limited to this example. For example, the configuration in which the programmable display device 1 is not necessarily connected to the drawing editor device 5 via the communication line 3 may be used. The programmable display 1 and the drawing editor device 5 may exist separately.

  The drawing editor device 5 has the function of the existing support device described in the background art, and develops data and the like (screen data and the like) for displaying the operation display screen on the programmable display 1. It has a function to assist a person etc. to create arbitrarily. However, the drawing editor apparatus 5 of this example has a function to be described later in addition to the function of the existing support apparatus. Details will be described later.

  Moreover, in the programmable controller system having the configuration shown in FIG. 1 or FIG. 3, the configuration in which the programmable display 1 is connected to the drawing editor device 5 via the communication line 3 is the configuration at the operation location of the programmable display 1. However, it is not limited to this example. For example, as another example, the configuration illustrated in FIGS. 1 and 3 may be regarded as a configuration at the manufacturing site of the programmable display device 1.

  In the case of the other example, for example, when the software / firmware is installed in the programmable display 1 after the manufacture of hardware of the programmable display 1 is completed on the manufacturer side, the drawing editor device 5 is set in the programmable display 1. Connecting. For example, arbitrary screen data is arbitrarily created on the drawing editor device 5 by a developer or the like for each programmable display 1. Then, the created screen data is downloaded and stored in the programmable display 1. Further, for each programmable display 1, a corresponding communication program is downloaded from the drawing editor device 5 and stored.

  Further, the drawing editor device 5 may previously store communication programs corresponding to various connected devices 4 in advance. As a specific example, the drawing editor device 5 may store 100 types or more of communication programs in advance. Among them, a developer or the like selects a communication program corresponding to the connection device 4 to be connected to each programmable display 1 and downloads it to the programmable display 1 (see, for example, Reference Document (Japanese Laid-Open Patent Application No. 7-1994)). No. 225831)).

  Conventionally, the programmable display device 1 storing screen data and communication programs downloaded from the drawing editor device 5 is shipped to a shipping destination, installed, and started to operate. At the shipping destination, one or more types of connection devices 4 are connected to the programmable display device 1. As described above, the screen data includes the allocated memory address for accessing the external memory device in the connected device 4, but the address setting or the like may be incorrect.

  As described above, the conventional method for dealing with such a case is to reset the drawing editor device 5 side. On the contrary. In this method, the user can change (reset) the allocated memory address on the programmable display 1 (in other words, at the shipping destination), and the work load can be reduced. Furthermore, at that time, the user can be prevented from making a setting mistake. This is realized by using, for example, “memory address settable range data” 24 described later.

  That is, as described above, the creation and download of the screen data and communication program itself may be regarded as substantially the same as in the past. However, the drawing editor device 5 of this example stores and manages various “communication I / F drivers 33” to be described later by adding “memory address settable range data” 24 to be described later to each communication program. ing. Then, among these various “communication I / F drivers 33”, a developer or the like can create a “communication I / F driver 33” corresponding to the connected device 4 connected to (or to be connected to) each programmable display 1. Select and download to the programmable display 1.

  Here, as described above, the connection devices 4 connected to each programmable display 1 are various. Therefore, in order to be able to cope with any connection device 4 connected, according to all types of the connection devices 4. It is conceivable that all “memory address settable range data” 24 is stored in the programmable display 1 in advance. However, since there are many types of connection devices 4 as described above, it is difficult to previously store all “memory address settable range data” 24 corresponding to all the connection devices in the programmable display 1. In other words, the programmable display device 1 is generally inferior in hardware performance to a personal computer or the like. Therefore, in reality, it is possible to store all “memory address settable range data” 24 corresponding to all connected devices in the drawing editor device 5 such as a personal computer. It was difficult to memorize.

  In response to the above-described problem, in this method, by using the “communication I / F driver 33”, only “memory address settable range data” 24 required by the programmable display device 1 can be easily displayed. It can be stored in the vessel 1. Details will be described later.

  Even if all the “memory address settable range data” 24 corresponding to all the connected devices can be stored in the programmable display 1, it is naturally possible to display the programmable display by this method. The effect of reducing the amount of data stored in the device 1 is obtained.

  Even when the configuration shown in FIG. 1 or FIG. 3 is provided at the operation site of the programmable display device 1, this technique can reduce the burden of changing the allocated memory address, and can prevent user setting mistakes at that time. Can be expected.

However, when the programmable display device 1 and the drawing editor device 5 are separated from each other, this method has a particularly remarkable effect.
The programmable controller system shown in FIG. 1 includes various connection devices 4 and a programmable display 1 that is connected to the various connection devices 4 via a communication line 6. The various connection devices 4 are, for example, various PLC main bodies and the temperature control device.

  Furthermore, the programmable display device 1 may be configured to be connected to the drawing editor device 5 via the communication line 3 (however, as described above, there is a configuration in which the drawing editor device 5 does not exist in the operation site). ).

  The programmable display 1 is provided with a plurality of communication interfaces 2 (communication ports), and is connected to various connection devices 4 and the drawing editor device 5 by the communication line 3 / communication line 6 connected to each communication interface 2. ing.

  The drawing editor device 5 has an existing function for supporting a developer or the like to arbitrarily create data or the like (screen data) for displaying the operation display screen on the programmable display 1. As is conventional, for example, various item images are prepared in advance, and the user repeats the operation of selecting a desired item image and placing it at a desired position to create the screen data. Furthermore, a desired allocation memory address (allocation memory area) and the like are set for each item. The screen data is downloaded from the drawing editor device 5 to the programmable display device 1.

  The programmable display 1 displays the said operation display screen based on screen data like the past. Then, the display content refreshing process is performed, for example, periodically during display. For this purpose, the above-mentioned allocation memory area related to each item on the operation display screen is accessed, the latest data is acquired, and the operation display screen having contents corresponding to the latest data is displayed. However, if there is a setting error with respect to the allocated memory address or the like, the display is not normal (other data cannot be read and displayed or data cannot be acquired (when there is no corresponding address)).

  Conventionally, in such a case, it has been necessary to correct (reset) the address in the drawing editor device 5. In contrast, in this method, the address can be corrected (reset) in the programmable display device 1. Furthermore, it is possible to prevent a setting error from occurring at that time.

  The drawing editor device 5 is realized by, for example, a general general-purpose computer (such as a personal computer). Therefore, although not shown in the drawings, it has a configuration of a general personal computer or the like. That is, for example, it has an arithmetic processor such as a CPU, a storage device such as a memory and a hard disk, an operation unit such as a keyboard and a mouse, a display unit such as a display, a communication function unit, and the like.

  A predetermined application program is stored in the storage device in advance, and various functions of the drawing editor device 5 are realized by the arithmetic processor executing the application program.

The programmable display 1 may also have a general hardware configuration. Therefore, a brief description will be given below with reference to FIG.
FIG. 2 is a hardware configuration example of the programmable display device 1 of this example.

  The programmable display 1 has a function of displaying each screen (operation display screen) based on the above-described screen data and the like in substantially the same manner as the above-described conventional example. The display process of the operation display screen includes the display content refresh process described above. That is, the external memory access process (data acquisition process from the allocated memory area) corresponding to each item on the screen is also included.

The illustrated programmable display 1 includes a display operation control device 10, a touch panel 18, a display 19, the communication interface 2, and the like.
The display operation control device 10 includes a CPU 11, a ROM 12 (flash memory or the like), a RAM 13, a communication controller 14, a graphic controller 15, a touch panel controller 16, and the like, which are connected to a bus 17.

  The CPU 11 is a central processing unit (arithmetic processor) that controls the entire display operation control device 10. The CPU 11 executes application programs (for example, a main body program 21 described later) stored in the ROM 12 in advance, thereby performing various arithmetic processes of the programmable display device 1 (particularly, various flowchart processes and functional block diagram processes described later). Function).

  The ROM 12 stores screen data (screen data 22 to be described later) described in the background art. As described above, the screen data 22 includes various data relating to each item such as switches and lamps arranged on the operation display screen (data such as images, display position coordinates and size, and the allocated memory address). Have.

  Here, in this method, the user can change the allocated memory address in the screen data 22 on the programmable display 1. Furthermore, it is possible to prevent a setting error from occurring at that time. The allocation memory address is set by, for example, “designation of an arbitrary connected device + designation of an arbitrary external memory device + designation of the arbitrary address”. A setting error is, for example, when an external memory device that does not exist in the specified connected device is specified, or when the specified address is not within a predetermined range of the specified external memory device. . Alternatively, there may be a case where the designated connected device itself does not exist (not connected to the programmable display 1). Details will be described later.

  By the processing of the CPU 11, for example, display target data based on the screen data 22 or the acquired data obtained by accessing the external memory is developed (drawn) on, for example, the RAM 13 (or a video RAM (not shown)). Details will be described later. Based on this drawing, the graphic controller 15 displays the above-described operation display screen on the display 19. The display 19 is composed of, for example, a liquid crystal panel, and a touch panel 18 is provided so as to overlap the liquid crystal panel.

  The detection result of the pressing operation (touch) position on the touch panel 18 by an operator or the like is taken into the CPU 11 or the like via the touch panel controller 16 and analyzed. For example, analysis is performed based on the display position coordinates and size data of each item. For example, when an operator or the like touches the display position of the switch image, the CPU 11 or the like analyzes that an operation on the switch has been performed.

  Further, the communication controller 14 performs communication (data transmission / reception and the like) with the connection device 4 and the drawing editor device 5 such as a PLC main body (not shown), a temperature control device, and the like via the communication interface 2.

FIG. 3 shows a software configuration diagram of the system.
In the programmable display 1, various programs / data such as a main body program 21, screen data 22, and communication program 23 are stored in, for example, the ROM 12 (flash memory or the like). The CPU 11 reads / executes / references these programs / data, etc., thereby performing display control of each operation display screen for the programmable display.

  This operation display screen includes the above-described numerical display, image display of various items such as lamps, switches, and the like. The display content of each item is, for example, a predetermined storage area (allocation memory area) of an external memory device of each connected device 4 It is updated from time to time to reflect the data (acquired data) acquired from.

  That is, the CPU 11 performs display control of the operation display screen based on the main body program 21, the screen data 22, and the acquired data. At that time, the display content of each item (each screen component) on the operation display screen reflects the content of the acquired data (numerical display such as temperature, lighting / extinguishing of the lamp, etc.). Note that this is an existing function and will not be described in further detail.

  The screen data 22 is, for example, a screen data file 32 arbitrarily created in advance on the drawing editor device 5 side, downloaded to the programmable display device 1 and stored. That is, the screen data 22 and the screen data file 32 may be regarded as substantially the same. Note that, for example, the screen data file 32 may be described as the screen data 22 without being particularly distinguished from each other.

  Further, the communication program 23 is, for example, a communication program file 35 stored in advance on the drawing editor device 5 side, downloaded to the programmable display 1 and stored. Here, there are usually a large number of communication program files 35, which may be called a communication program group. Any one or more types of communication programs in each communication program file 35 (communication program group) are downloaded to the programmable display 1 and stored as the communication program 23.

  Here, each of the communication program files 35 (various communication program groups) is created in advance corresponding to the communication protocol of the various connection devices 4. And the communication program file 35 corresponding to the connection apparatus 4 (the communication protocol etc.) connected to the programmable display 1 of a download destination is downloaded to the said programmable display 1 among various communication program groups. Become. Then, the communication program 23 is stored.

  The communication program 23 of the programmable display device 1 is a program for communicating with the connection device 4 via the communication line 6. Usually, each connected device 4 has a unique communication protocol (communication rule) for each model and performs communication between the programmable display 1 and the connected device 4 in accordance with this communication rule. Therefore, the communication program 23 needs to be developed for each model of each connected device 4. Of course, the CPU 11 and the like execute the communication program 23 to realize communication processing with the connected device 4.

  There are various manufacturers / models of the connection device 4 such as the PLC main body, and each manufacturer / model has its own communication program. Depending on the manufacturer / model of the connection device 4, there are many communication programs depending on the manufacturer / model. The types are created and stored in the drawing editor device 5 as the numerous communication program files 35.

  The various communication program files 35 corresponding to the various connection devices 4 described above are stored in the drawing editor device 5 and a part of them is downloaded to the programmable display device 1 itself as an existing technology. Also good. However, in this method, as shown in the drawing, the drawing editor device is in the form of a “communication I / F driver 33” in which the corresponding memory address settable range data 34 is added to each communication program file 35, respectively. Stored and managed on the 5th side. That is, “communication program file 35 + memory address settable range data 34” is referred to as “communication I / F driver 33”.

  That is, various memory address settable range data 34 corresponding to the various connected devices 4 is created in advance. Then, the communication program file 35 corresponding to the same connected device 4 and the memory address settable range data 34 are paired as the “communication I / F driver 33”.

  As described above, since each communication program file 35 is a communication program created corresponding to each manufacturer / model, the creator, etc. must know the specifications of the connected device that is the communication partner. become. In particular, for example, various information (for example, device name, memory unit, numerical value format, address range (minimum, maximum), etc., which will be described later) regarding the external memory device in the connected device as the communication partner are known in advance. The creator or the like can create the memory address settable range data 34, which is the “various information related to the external memory device in the connected device as the communication partner”, for each connected device. The memory address settable range data 34 is stored and managed as a pair with the corresponding communication program file 35 as the communication I / F driver 33. That is, the drawing editor device 5 includes various (many) connected devices. Various (multiple) communication I / F drivers 33 corresponding to 4 are stored.

  Then, the communication I / F driver 33 corresponding to the connected device 4 connected to the display device 1 is connected to the programmable display device 1 as an arbitrary download destination from among various (many) communication I / F drivers 33. to download. This is stored in the programmable display 1 as the illustrated communication I / F driver 25. As illustrated, the communication I / F driver 25 includes a communication program 23 and memory address settable range data 24. Naturally, these correspond to the above-described communication program file 35 and memory address settable range data 34.

  In addition to the existing functions, the main body program 21 further displays a screen for changing the allocated memory address of the screen data 22 (not shown in FIG. 3; a window 90 and a dialog 100 described later), and this screen. It has a function for allowing the user to input / select a desired address. Then, a process of updating the allocated memory address of the screen data 22 with the input / selected address is also performed. However, it is controlled not to update the allocated memory address when there is a setting error (to prevent an address setting error). Further details will be described with reference to flowcharts described later.

  Communication between the programmable display 1 and the drawing editor device 5 is performed by, for example, the main body program 21 and the drawing editor 31 (a communication function is incorporated in the drawing editor 31). This is not particularly relevant and will not be shown or described.

  As described above, the communication program file 33 group (a plurality of communication programs developed for each model) is stored in advance in an HD (hard disk) (not shown) in the drawing editor device 5. Then, when the user selects / designates an arbitrary connected device 4 using the drawing editor 31, the drawing editor device 5 transfers (downloads) a communication program file 33 corresponding to the selected connected device 4 to the programmable display 1. Then, the communication program 23 is stored. This is substantially the same as the conventional one, but in this method, the communication I / F driver 33 is downloaded and stored instead of the communication program alone as described above.

  As a result, the user simply downloads the memory address settable range data 34 corresponding to the connected device 4 connected to the downloadable programmable display 1 together with the downloadable programmable display 1. Will be stored. Thereby, each programmable display 1 can memorize | store only the data required in order to make a user change address setting arbitrarily, preventing a setting mistake generation | occurrence | production.

  The program for realizing various processes such as access to the allocated memory area and screen display may be included in the main body program 21 or may be included in the screen data 22, for example. In any case, when the CPU 11 executes such a program, for example, various operations of the programmable display 1 are realized.

  Here, the drawing editor 31 of the drawing editor device 5 also has a support function that allows the user to create a desired operation display screen (screen data thereof). As described above, various items created in advance are stored in the hard disk or the like of the drawing editor device 5. These various items are displayed in a list by the creation support function of the operation display screen by the drawing editor 31, and the user selects a desired item and arranges it at a desired position. This function itself is substantially the same as the conventional one.

  Note that the drawing editor device 5 is, for example, a personal computer or the like, and has a general-purpose computer configuration (CPU, storage unit (hard disk, memory, etc.), communication unit, operation unit (mouse, etc.), display) although not particularly shown. Have. The processing function of the drawing editor 31 is realized when the CPU executes an application program stored in advance in the storage unit. The processing function itself of the drawing editor 31 may be almost the same as the conventional one, and the difference is the storage data as the communication I / F driver 33, the download processing, and the like. That is, the drawing editor device 5 has not only the existing function but also a new function shown in FIG. 4, for example. These existing functions and new functions are realized when the CPU (not shown) or the like executes an application program stored in advance in a storage unit (not shown).

FIG. 4 is a functional block diagram of the programmable display 1 of this example.
The programmable display device 1 of this example is a programmable display device connected to one or more connection devices 4, and includes, for example, an item information storage unit 40, an item display unit 41, an access information change unit 42, and a connection device information storage unit. 43, a communication unit 44, and the like. These various functional units are realized, for example, by the CPU 11 executing a predetermined application program stored in advance in the ROM 12.

  The item information storage unit 40 stores access information indicating an access destination corresponding to each item on the operation display screen. The access information is, for example, partial information of the screen data 22.

The item display unit 41 acquires data from the access destination based on the access information in the item information storage unit 40, and displays the item using the acquired data.
Note that the item information storage unit 40 and the item display unit 41 may be regarded as existing configurations.

The access information changing unit 42 causes the user to arbitrarily change the access information related to an arbitrary item to be changed.
Further, the access information changing unit 42 can arbitrarily change the access information related to the arbitrary item to be changed while preventing setting errors.

  Here, for example, the access information is an arbitrary address in an arbitrary external memory device in an arbitrary connected device 4. The connected device information storage unit 43 stores memory information 43 a including an address settable range related to the external memory device in the connected device 4 connected to the programmable display 1. An example of the memory information 43a is settable range information 70 described later.

  In addition, when there are a plurality of connection devices 4 connected to an arbitrary programmable display 1, a plurality of memory information 43 a corresponding to each of the plurality of connection devices 4 is stored in the connection device information storage unit 43. become. Further, only the memory information 43a corresponding to the connection device 4 connected to the programmable display device 1 is downloaded from the drawing editor device 5 and stored.

Then, the access information changing unit 42 realizes prevention of the setting mistake based on at least the address settable range (an example is a settable address range described later).
That is, for example, when the user inputs an arbitrary new address and the new address is within the corresponding address settable range, the access information changing unit 42 is an address in the access information related to the item to be changed. To the new address. As a result, it is possible to prevent occurrence of the setting error (for example, Example 1 described later).

  Further, the access information changing unit 42 causes the user to input an arbitrary new connection device, an arbitrary new memory device, and an arbitrary new address, for example. Then, it is determined whether or not the memory information 43a corresponding to the new memory device of the newly connected device is stored and the new address is within the address setting range in the memory information 43a. If this condition is satisfied, the connected device, memory address, and address in the access information related to the item to be changed are changed to the new connected device, new memory device, and new address. By doing so, it is possible to prevent the occurrence of setting errors (for example, Example 1 described later).

  Alternatively, the access information changing unit 42 allows the user to select an arbitrary new address from among the addresses within the above address setting range according to the arbitrarily selected new connection device and new memory device, for example. Then, the address in the access information related to the item to be changed is changed to the selected new address. In this way, it is possible to prevent the occurrence of the setting error (for example, Example 2 described later).

  Further, the access information changing unit 42 causes the user to select any of the newly connected devices, for example, and presents one or more memory devices corresponding to the selected new connected device based on the memory information 43a. Then, the user selects an arbitrary new memory device from the presented memory devices. Further, the connected device and the memory device in the access information related to the item to be changed may be changed to the selected new connected device and new memory device (for example, Example 2 described later).

  Further, the programmable display 1 stores, for example, a communication program (communication program 23 or the like) and memory information 43a corresponding to each connected device 4 connected to itself. And the said communication part 44 communicates with the arbitrary connection apparatuses 4 by the corresponding communication program 23. FIG. The communication program 23a and the memory information 43a are downloaded from the support device (drawing editor device 5) and stored.

In the example illustrated in FIG. 4, the support device (drawing editor device 5) includes a communication driver storage unit 45, a download unit 46, a setting unit 47, and the like.
The communication driver storage unit 45 adds, for each communication program (communication program file 35, etc.) corresponding to various connection devices, memory information 43a (memory address settable range data 34) related to the connection device corresponding to the communication program. Various communication drivers (communication I / F driver 33 and the like) are stored.

  The download unit 46 downloads, to the programmable display 1, a communication driver (for example, determined by a developer or the like) related to the connection device 4 connected to the downloadable programmable display 1 among various communication drivers. And memorize it.

  Moreover, the setting part 47 makes a user arbitrarily set the access information according to arbitrary programmable displays 1. FIG. Then, the download unit 46 downloads and stores the set access information in an arbitrary programmable display device 1.

Here, specific examples of the screen data 22 and the memory address settable range data 24 will be described.
5A and 5B are specific examples of the screen data 22. FIG.

6A, 6B and 7 are specific examples of the memory address settable range data 24. FIG.
In the example shown in FIG. 5A, the screen data 22 includes data items such as an item type 51, coordinates 52, size 53, “data for each item type” 54, and memory address information 55. Note that information of each record shown in the figure is stored for each item. FIG. 5B shows a detailed example of the memory address information 55.

  The item type 51 stores item type identification information indicating the type (switch, lamp, numerical display, etc.) of the item. “Data for each item type” 54 includes, for example, an image related to the item (for example, a lamp on image and a lamp off image for a lamp item, or a switch ON image and a switch OFF image for a switch item). Various item images) are stored.

Coordinate 52 and size 53 store information indicating the display position and size of the item image on the operation display screen.
The memory address information 55 is information related to the external memory access process, and includes information such as the allocated memory address. Then, this memory address information 55 is the target of setting data correction / change by this method.

In the example shown in FIG. 5B, the memory address information 55 includes a memory model 61, a memory access 62, a device name 63, an address 64, a data number 65, and the like.
The memory model 61 is identification information of the connected device 4 to be accessed.

The memory access 62 indicates the access format (1 bit access, 16 bit (word) access, etc.) to the external memory device indicated by the device name 63.
The device name 63 is identification information of an external memory device to be accessed.

The address 64 is the head address of the access destination storage area in the external memory device indicated by the device name 63.
The number of data 65 indicates, for example, the capacity of the storage area to be accessed. For example, if the address 64 is “101” and the number of data 65 is “3”, the addresses 101 to 103 are the storage areas of the access destination.

  The storage area indicated by the address 64 of the memory device indicated by the device name 63 in the connected device indicated by the memory model 61 corresponds to the allocated memory area. Changes to be made by this method are mainly allocated memory areas.

Next, a specific example of the memory address settable range data 24 will be described with reference to FIGS. 6 (a), 6 (b) and FIG.
FIG. 6A is a schematic data configuration example of the entire memory address settable range data 24.

  Here, from the above, when there are a plurality of connection devices 4 connected to the programmable display device 1, a plurality of types of memory address settable range data 24 are also stored. That is, the memory address settable range data 24 corresponding to each connected device 4 is stored.

  Each memory address settable range data 24 includes settable range information 70 corresponding to each memory device of the corresponding connected device 4. In other words, when there are a plurality of external memory devices in the corresponding connection device 4, a plurality of settable range information 70 is provided as shown. FIG. 6A shows an example of the memory address settable range data 24 related to an arbitrary connected device 4 (here, it is assumed that the connected device A is assumed).

  Here, it is assumed that the connected device A includes three memory devices D, W, and M. Thus, the memory address settable range data 24 related to the connected device A is composed of the three settable range information 70 shown in the figure corresponding to the three memory devices D, W, and M, respectively.

  Further, here, each settable range information 70 includes a device No. Shall be assigned. Device No. Are sequentially assigned serial numbers such as 0, 1, 2, 3,... Accordingly, in the illustrated example, the first settable range information 70 includes a device number. '0', the second is the device number. '1', the third is the device number. '2' is assigned to each.

  This device No. Is used, for example, when a list is displayed in the device selection field 102 on the memory address change dialog 100 shown in FIG. Details will be described later.

  In addition, for example, with respect to another connection device 4 (referred to as connection device B), the device No. '0', device no. '1' etc. may be assigned. Of course, in this example, each of the device No. The memory device names corresponding to will be different (although it may happen to be the same). For example, the device no. For “0”, the memory device D is used as described above. For “0”, for example, the memory device C is used.

That is, the device No. Can be used in common for all connected devices, but the contents (corresponding memory device) are appropriate for each connected device.
A specific example of the settable range information 70 is shown in FIG.

  In the example shown in FIG. 6B, the settable range information 70 includes a device name 71, a memory unit 72, a numerical format 73, an address minimum 74, an address maximum 75, and the like. Although not shown, the device No. There may be.

The device name 71 is identification information of the external memory device.
The memory unit 72 indicates the access format (1-bit access, 16-bit (word) access, etc.) of the external memory device indicated by the device name 71, substantially the same as the memory access 62.

  The numerical format 73 is data indicating how to display and increment the numerical value of the address of the external memory device indicated by the device name 71 (for example, DEC (decimal number), HEX (hexadecimal number), OCT ( Octal) etc.).

  The address minimum 74 and the address maximum 75 indicate a settable address range of the external memory device indicated by the device name 71. For example, if the minimum address 74 = '0' and the maximum address 75 = '65535', the settable address range is 0-65535. In this method, addresses outside this settable address range are processed so that they cannot be set substantially (error even if set by the user, not presented as an option, etc.). Can be prevented.

  FIG. 7 shows a specific example of the settable range information 70 for each of the three types of external memory devices, device D, device W, and device M in the connected device A, as a temporary example.

  Hereinafter, on the programmable display 1 side, the setting information (one or more of the memory model 61, the device name 63, and the address 64) regarding the allocated memory address related to an arbitrary item can be arbitrarily changed by the user, A specific example of processing for preventing the occurrence of an address setting error will be described. Here, the following two examples (Example 1 and Example 2) will be described, but the present invention is not limited to these examples.

  Schematically, in Example 1 below, resetting of addresses and the like can be freely performed by the user, but the presence or absence of a setting error is checked, and if there is a setting error, the address is not changed (user (The input contents are not reflected in the device name 63, the address 64, etc.).

In the second embodiment, the user selects and inputs an address and the like, and can select an address within the settable address range, but cannot select an address outside the settable address range. It has become. This is not limited to the address, and the same applies to the resetting of the connected device name (memory model 61) and the external memory device name (device name 63). In other words, only correct choices regarding the connected device name are presented (thus, any selection does not constitute a setting error). Similarly, only correct choices are presented for external memory device names (so no choice will result in misconfiguration)
Hereinafter, Example 1 will be described with reference to FIGS. 8, 9, and 10.

8 and 9 are flowcharts (1/2) and (2/2) of the address changing process according to the first embodiment. In the following description, FIG.
When the user performs a predetermined operation, the address changing process shown in FIG. In the illustrated example, the predetermined process is a “long press” operation on an arbitrary item that the user has determined to be an address change target, but is not limited to this example.

  In the processing example illustrated in FIG. 8 and the like, when the user performs a “long press” operation on the desired address change item (step S11, YES), for example, the memory address illustrated in FIG. A change window 90 is displayed (step S12). On the memory address change window 90, a display field 91, an input unit 92, a “change” button 93 and the like are displayed. For example, a numeric keypad or alphabetic input keys are displayed on the input unit 92, and the user can input a desired alphabet or numerical value. The user performs an input operation on the input unit 92 such as a desired memory model, a desired external memory device, a name / identification information of a desired address, and a numerical value. This input content is displayed in the display column 91.

In this example, a name (memory device name) is input for the external memory device. However, the present invention is not limited to this example, and identification information (ID or the like) may be used.
Note that the present invention is not limited to this example. For example, the user may be configured to perform only a desired address input operation (change). In other words, the settings of the memory model (connected device) and the external memory device may be configured so as not to be changed. In this example, the memory model 61 and the device name 63 may be read and displayed (only display and cannot be changed). Or you may comprise so that a memory model (connection apparatus) cannot be changed.

The user confirms the display content of the display field 91 and, if it is OK, operates the “change” button 93.
Thus, the following process corresponding to this operation is executed (step S13).

  First, based on the memory model (designation of a desired connected device 4) input by the user, the communication I / F driver 25 (the memory address settable range data 24) corresponding to the connected device 4 is determined. For example, when the connection device A is designated, the communication I / F driver 25a (the memory address settable range data 24a) for the connection device A shown in the figure is determined.

  Then, using the determined memory address settable range data 24, it is checked whether or not the memory device name or address input by the user is normal. When there is no memory address setting range data 24 corresponding to the memory model input by the user, an input error may be notified (for example, a setting error of the connected device is notified).

  In the check process, for example, first, the settable range information 70 corresponding to the memory device name input by the user is acquired. For example, the settable range information 70 in which the device name 71 matches the memory device name input by the user is acquired. However, if there is no applicable settable range information 70, error information such as “memory device name input error” may be notified.

  In the case where only the address can be input, the memory model 61 and device name 63 related to the item to be changed are used instead of the memory model and memory device name input by the user. .

  Then, it is checked whether the address input by the user is within the settable address range indicated by the minimum address 74 and the maximum address 75 of the acquired settable range information 70 (step S14).

  When the user input address is within the settable address range, it is determined as normal (step S14, YES), and the process proceeds to step S15. On the other hand, when the user input address is out of the settable address range, it is determined as abnormal (NO in step S14), and the process proceeds to step S16.

  In step S15, the screen data 22 is updated with the user input data. That is, the information (memory model 61, device name 63, address 64, etc.) related to the item whose address is changed in the screen data 22 is rewritten (overwrite / update) with the memory model, memory device name, address, etc. inputted by the user. To do). Of course, when only the address can be changed, only the address 64 is changed according to the address input by the user.

On the other hand, in step S16, an error display as shown in FIG. 10B, for example, is performed without performing the process of step S15.
When any one of the processes in steps S15 and S16 is executed, this process ends.

  In the initial screen of the memory address change window 90, the display address 91 may display the current (before change) set address contents. This obtains and displays the data (device name 63, address 64, etc.) of the address change target item from the screen data 22. The user confirms this display content and inputs a desired address or the like when determining that the change is necessary.

Next, the second embodiment will be described with reference to FIGS.
11 and 12 are flowcharts (1/2) and (2/2) of the address change process according to the second embodiment. In the following description, FIG. 11 and the like are not particularly distinguished.

When the user performs a predetermined operation, the address changing process shown in FIG. 11 and the like is started. In the example shown in the figure, the predetermined process is a “long press” operation on the item whose address is to be changed.
That is, in the processing example of FIG. 11 and the like, when the user performs a “long press” operation on the desired address change item (step S21, YES), for example, the memory address change dialog 100 shown in FIG. (Step S22).

  In the illustrated example, on the memory address change dialog 100, for example, selection candidates are presented to the user for each of the connected device, device, and address, for example, and the user selects a desired selection candidate.

  First, names / IDs and the like of all the connected devices 4 connected to the programmable display device 1 are displayed in a list in the connected device selection field 101 (herein referred to as names). In the illustrated example, a list of connected device names “PLC1”, “PLC2”, and “PLC3” is displayed. These connected device names are in each memory address settable range data 24, for example.

  When the user selects a desired connected device, memory address settable range data 24 corresponding to the selected connected device is acquired. Thus, selection candidates are sequentially presented for the external memory device and the address based on the acquired address settable range data 24 (step S23). That is, first, the device names 71 of all the settable range information 70 in the acquired address settable range data 24 are displayed in a list in the device selection field 102 shown in the figure. When the user selects a desired external memory device on the device selection field 102, the settable range information 70 corresponding to the selected external memory device is acquired.

  As a result, only the addresses within the settable address range based on the minimum address 74 and the maximum address 75 of the acquired settable range information 70 are displayed as options in the illustrated address selection field 103. For this display, data such as a numerical format 73 may be further used.

  The user operates the “change” button 104 shown in the figure after operating the up and down buttons in the address selection field 103 to display the desired address value (step S24).

  Thus, the screen data 22 is updated according to the user selection results in the connected device selection column 101, device selection column 102, and address selection column 103. That is, the information (memory model 61, device name 63, address 64, etc.) related to the item whose address is changed in the screen data 22 is rewritten by the connected device, external memory device, address, etc. selected by the user (overwriting / writing). Update) (step S26).

  However, it can be configured such that the user can input an arbitrary address or the like, and a normal check similar to step S14 of the first embodiment may be performed according to this example (step S25). Of course, if it is determined as abnormal (step S25, NO), the process of step S26 is not performed. Instead, for example, processing for displaying an error display screen shown in FIG. 13B is performed (step S27). However, the processes of steps S25 and S27 are not necessarily required.

  As in the first embodiment, the second embodiment is not limited to the above example, and may be configured such that only the address can be changed. In the case of this form, the settable range information 70 corresponding to the memory model 61 and the device name 63 related to the item whose address is to be changed is acquired. Only addresses within the settable address range based on the minimum address 74 and the maximum address 75 of the acquired settable range information 70 can be selected in the address selection column 103. In this embodiment, for example, instead of the connected device selection column 101 and the device selection column 102, a display column (not shown) for displaying the memory model 61 and the device name 63 related to the address change target item is provided. You may be made to do.

  Here, when the list of the device selection field 102 on the memory address change dialog 100 shown in FIG. The processing using the will be described.

  The device selection field 102 is, for example, a combo box. For example, in the case of the connection device A described above, the above-described three memory device names D, W, and M are displayed in a list and selected. At this time, the display order may be various display orders as shown in FIG. In determining the display order, the device No. Is used. For example, device No. Are displayed in ascending order. In this example, in the example of FIG. 6A, the memory device names are displayed in the order of “D” → “W” → “M” as shown in FIG. 13A.

  For example, when the developer or the like wants to display in the desired order, the device number of the memory address settable range data 24 is displayed. Is set arbitrarily. If the device No. If is not used, it will be necessary to set a table in which each memory device name is associated with the display order. Of course, if the display order is arbitrary, such a table or the device No. Is not always necessary.

  As described above, in the programmable display 1 or the like of the present example, in the programmable display 1 or the like, the user changes the setting information (memory address information 55 or the like) of the allocated memory address related to an arbitrary item on the operation display screen. be able to. Therefore, the change work burden can be reduced as compared with the conventional case. Further, at that time, it is possible to prevent the occurrence of a setting error such as an address. In addition, the amount of data necessary for the setting error prevention process can be greatly reduced (or the process can be executed by the programmable display 1). Only the data necessary for the setting error prevention process can be reliably delivered from the drawing editor device 5 for each programmable display 1 (because it is delivered as a set together with the communication program necessary for the programmable display 1). .

According to the above-described programmable display 1 or the like, it is possible to correct / change the screen data (its allocated memory address, etc.) already stored on the programmable display 1 side on the programmable display 1 side.・ Reduction work burden can be reduced. Furthermore, setting errors can be prevented from occurring.
