Here, the actual operating conditions of the above PLC system are There are various types of users or system builders of PLC systems, and for example, the following description is known.

The above-mentioned "picture data" is stored in a programmable display and executed, but the support device is created. Therefore, there are many cases where the screen data remains on the support device side. In addition, the screen data is upgraded by the version, and on the side of the support device, there is a case where not only the latest version but also the old version is stored.

The screen data saved on the programmable display is basically The latest version (current version). Thereby, the screen data stored in the programmable display is regarded as the master, and when the version upgrade version is created, the screen data (master) on the programmable display side is uploaded to the support device, and the screen data (master) is There are quite a few examples of the basic version to be upgraded.

At this point, if the programmable display fails, it becomes no The method extracts the picture material (master).

In addition, the screen data is usually managed by the manufacturer who is making the commission or the commissioner who is commissioned. However, if the operator changes, the management becomes complicated, and in particular, the screen data stored in the support device may be lost. The screen data remains only on the side of the programmable display. In the case shown above, if the programmable display fails and the screen data cannot be taken out, the screen data will be lost.

In addition, if the screen is saved/executed on the programmable display When the master is tampered with, there is a high possibility that some abnormal actions will occur. If the tampering is not detected, there is a possibility that the version upgraded version may cause the tampering effect afterwards.

On the other hand, there are also screens that are stored in the support device. The data is based on the case of a version upgrade. However, at this time, there is a case where the developer or the like mistakenly creates an upgraded version based on the old version of the screen material. At this time, if there is a process that is present in the current version but not in the old version, the process will disappear in the version upgrade version, which may cause problems. In addition, there is a case where the screen material stored in the support device is lost due to the change of the operator or the like.

The subject of the present invention provides a one-way management The program display maintains/executes the data of each screen for data retention, and prevents or suppresses abnormal operations caused by tampering of the screen data held on the programmable display side, thereby enabling the display with improved reliability Management system, its server device, programmable display, etc.

The display management system of the present invention is a system in which a programmable display and a server device are connected to a network, and has the following constitution.

The programmable display system has a first screen data memory means for storing picture data for the programmable display.

The server device has a second screen data memory means for storing screen data of each of the programmable displays.

Either or both of the programmable display and the server device have: determining whether the screen data stored in the first screen data storage means matches the screen data stored in the second screen data storage means Screen data determination means.

Next, for example, the programmable display system further includes an operation control means for controlling the operation of the programmable display based on the result of the determination of the coincidence/disagreement of the screen data by the screen material determining means. For example, when the programmable display is activated, the determination of the coincidence/disagreement of the screen data by the screen data determining means is performed, and if the determination result is inconsistent, the programmable control means does not permit the programmable display to be activated.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a configuration diagram of a PLC system (display management system) of this example.

The illustrated display management system includes a programmable display 10, a server device 20, and a drawing device (support device) 30. The function of the drawing device 30 may be included in the configuration of the server device 20. Or conversely, the painting device 30 can also have the function of the server device 20 (in which case the painting device 30 can also be considered as not). Here, the function of the drawing device 30 refers to a support function for creating/editing general picture data existing in the past. In other words, it is possible to create a new screen material by allowing any user to perform a new creation/update of an arbitrary screen material. The screen material (original code) to be created is basically the same as the conventional technique, and is compiled by a compiler (not shown) included in the drawing device 30. After the translation, it is delivered to the programmable display 10 or the like, but in the present description, the compilation processing is not described one by one and is omitted.

In addition, in the present description, "picture data" refers not only to The application screen data (existing general screen data) created by each user is also included, for example, the screen material provided by the display manufacturer. In other words, "picture data" means all data/programs used to make certain display or input acceptances in a programmable display.

Here, first, the features of the illustrated display management system will be briefly explained.

First, in the prior art, for example, when a user creates a new screen material (a new version, a version upgrade, etc.) on a painting device (support device), the screen material is downloaded from the drawing device to the Program display and keep it/execute. In addition, in the prior art, when a new programmable display is replaced due to a malfunction of the programmable display, etc., the screen data held by the drawing device is downloaded from the drawing device to the new programmable display and held/ carried out.

On the other hand, in the present method, for example, a form in which the screen device data is downloaded from the image forming apparatus 10 by the drawing device (supporting device) 30 may be used as an example, but the form may not be performed. . When the image data is not downloaded by the drawing device (support device) 30 to the programmable display device 10, the image data is transferred to the server device 20 by the drawing device 30 and stored, and the server device is stored. 20 Download to the compliant programmable display 10.

However, this is an example. In other cases, it may be as above. In the same manner as in the related art, the screen device is downloaded from the drawing device 30 to the programmable display device 10. However, in the case of this other example, the screen data must be transferred from the programmable display 10 to the server device 20 for backup storage. Further, at this time, after checking whether the screen material transferred to the server device 20 is normal, the screen data may be memorized in the server device 20 only when it is normal. In this way, it is possible to cope with a situation in which the screen data is broken due to a communication error or the like.

In the case of the above example, the drawing device 30 is, for example, each When the new screen material (first edition or version upgrade version, etc.) is created in the second time, the screen material is delivered to the server device 20 and saved. At this time, the identification information (some identification IDs for display, or IP address, etc.) of the programmable display 10 that holds/executes the screen data is also transmitted and stored on the server device 20 side. In the server device 20, for example, when the screen material to be delivered is stored, the identification information is stored in association with each other.

Then, the server device 20 will be delivered to itself. The saved screen data is downloaded to the appropriate programmable display 10, respectively. This is done, for example, each time a new picture material is delivered by the painting device 30, that is, the delivered picture material is saved and downloaded to the appropriate programmable display 10. However, it is not limited to this example. For example, the registered programmable display can be displayed in a list, and the user or the like can select an arbitrary programmable display to download the appropriate screen data to the selected programmable display.

Further, in the case of the above example, for example, The newly set programmable display 10 can be set without maintaining the screen data in advance. At this time, of course, the screen data suitable for the programmable display 10 is delivered to the server device 20 by the drawing device 30 and stored. Next, the programmable screen 10 can be downloaded and held by the server device 20 in the initial state of the programmable display device 10, whereby the programmable display device 10 can be started.

In short, the screen data of each programmable display 10 is also recorded. In the case of the server device 20, even if, for example, the screen data of any programmable display 10 disappears for any reason, the screen data backed up by the server device 20 can be used for repair. Alternatively, even if the screen data stored in the drawing device 30 is lost for some reason or the drawing device 30 does not function, it can be used continuously (for example, when the replacement is possible due to a malfunction of the programmable display 10, if a backup is used The screen data on the server 20 can be).

In order to achieve the above actions, for example, by way of example, each process The display 10 or the drawing device 30 is formed to communicate with the server device 20 through some network. The network is, for example, a serial communication line, an internal network such as a LAN, an Internet, or the like. Therefore, the programmable display 10 also has a communication function for performing communication through the network, such as assigning an IP address and the like.

On the other hand, the server device 20 can be said to be plural The screen data of the program display 10 is managed in a unified manner. The server device 20 can display a plurality of programmable programs if the screen data of each programmable display 10 is managed through the Internet. The screen data of the device 10 is managed in a unified manner. The server device 20 is, for example, a server that provides a one-management-type screen data security service as described above, but is not limited to this example.

The server device 20 can also be used as an internet network. The function of the web server that provides the screen data security service. The server device 20 is, for example, a service that provides service start, registration of a programmable display, and update of screen data on the Internet. At this time, the drawing device 30 has a browser function, and the server device 20 displays, for example, a screen (not shown) for accepting the start or registration of the service on the browser screen. The user of the drawing device 30 performs an input operation for starting or registering the service on the screen (not shown).

At the beginning of the service offering as shown above, In other words, the drawing device 30 that manages (creates/saves/edits, etc.) the screen material of any one or more of the programmable displays 10 is requested to start service provisioning to the server device 20 via the network. At this time, the drawing device 30 transmits the predetermined information (some identification IDs, IP addresses, and the like for the display) of the programmable display 10 managed by the own device to the server device 20 and registers them. The server device 20 performs maintenance/management of the screen material with respect to the programmable display 10 to be registered.

That is, for example, each time there is a new login, the server device The 20 system executes processing for storing the screen material of the programmable display 10 to be registered in the own device. Further, the server device 20 executes a process for acquiring an updated version and storing it in its own device each time there is some update (version upgrade, etc.) with respect to the saved picture material.

These processes can also be implemented in a variety of ways. For example, also A new or updated version of the screen material can be obtained via the network by the executable display 10 as an object (for example, by a backup request described later). Alternatively, the painting device 30 can also transmit and update the new or updated version of the screen data to the server device 20 via the network (in this case, the server device 20 can also transfer the new or updated version to the programmable display device 10. Screen information).

In short, to be kept on the side of the server device 20 Some processing is performed in such a manner that the screen data held by each of the registered programmable displays 10 is in the same state of the screen data.

In addition, it can also be held on the side of the server device 20 described above. The screen data is used to check whether the picture data held by the programmable display 10 has been tampered with.

Here, the possibility that the screen material held on the server device 20 side is falsified is not "0", and is extremely low compared to the programmable display 10.

Thus, if the display is on any programmable display 10, the display When the screen data held by the device 10 does not match the screen data held on the server device 20 side, it is considered that the screen data held by the display 10 is falsified. Next, if the screen data is inconsistent (there is a possibility of tampering), if the programmable display 10 is activated, the activation is not permitted, and if it is in operation, the operation is stopped. Since the PLC body (not shown) connected to the programmable display 10 malfunctions due to falsification, various control target devices connected to the PLC main body may have abnormal operation. Sex, there is also the possibility of danger in the body of the operator. In this method, the use of tampering before and after the use of the application can prevent/suppress the abnormal situation as shown above.

When the programmable display 10 is started, or when starting up After the start of the application, the screen data held on the server device 20 side is used at any time or periodically during the operation to check whether or not the screen data on the programmable display unit 10 side is falsified. As a result, if the screen material held/executed on the programmable display 10 side is tampered with, it is highly probable that the problem can be made before the problem becomes serious.

In short, in this method, each programmable display 10 can be made. The held/executed picture material is held at the server device 20, whereby, for example, the following can be achieved.

‧ The screen data can be left only on the side of the programmable display 10, etc., and the screen data will not be lost even if the programmable display 10 fails.

‧ It is possible to check whether or not the screen data on the side of the programmable display 10 is falsified. In particular, it is possible to detect that the tampering is not started when it is checked by the start. In addition, tampering checks are carried out at any time/regularly during the operation, so that when there is tampering, it can be immediately responded.

The following is a detailed description of the display management system shown in FIG. Various components/functions, etc.

As described above, the illustrated display management system includes a programmable display 10, a server device 20, and a drawing device (support device) 30. Next, although not specifically illustrated, the programmable display 10 and the server device 20 are Connected to the Internet, you can send and receive data to each other. The network is, for example, a serial communication line, an internal network such as a LAN, an external network such as the Internet, and the like. Further, the programmable display 10 is connected to the external device 100 (the PLC body or the control target device, etc.), but the details are not particularly described.

In addition, the painting device 30 is as conventional as, for example, transparent. An internal network such as a serial communication line or a LAN communicates with the programmable display 10. Next, as in the related art, the drawing device 30 can also download the screen data created on the own device to the programmable display 10 through the internal network. However, the present invention is not limited to this example. As described above, the image data created on the own device by the drawing device 30 can be delivered to the server device 20 through the external network. Of course, at this time, the drawing device 30 can communicate with the server device 20 through the above network.

The above programmable display 10 is, for example, in the illustrated example, There are a first memory 11 and an operation control unit 12 that hold screen data. The screen data stored in the first memory 11 is screen data for the programmable display, and the programmable display 10 displays the above-mentioned monitoring/control screen and the like using the screen data.

Among them, as is well known, the picture data is basically per Each programmable display corresponds to the author. Therefore, the picture material held by each of the programmable displays 10 is substantially completely different. Further, by this, the server device 20 transfers (of course) the arbitrary screen data among the screen data groups held by itself to the programmable display 10 suitable for the screen material. Of course, therefore, wait Although not shown in the drawings, the server device 20 holds information indicating which screen material is suitable for which programmable display device 10.

The operation control unit 12 will be described later in detail, but is summarized The operation of the programmable display 10 is controlled in accordance with the result of the coincidence/inconsistency determination of the screen data obtained by the screen data determining unit 2 described later.

The server device 20 basically has a plurality of programmable programs The second memory 21 of each screen material of the display 10 or the like. Further, the server device 20 may be any one or more (or all) of the various functional units shown in the drawings, and details will be described later.

In addition, in the programmable display 10 and the server device 20 The transfer unit 1 is provided in at least one of them (or both). The screen material determination unit 2 is provided in at least one of the programmable display 10 and the server device 20 (or both).

The transfer unit 1 is installed on the programmable display 10 - server Transfer processing of 20 screen data. That is, by the transfer unit 1, at any time, any one of the programmable display 10 and the server device 20 transfers the screen material held by the other to the other through the network.

For example, the transfer unit 1 of the server device 20 will be maintained Any of the screen data among the screen data of the second memory 21 is transferred to the appropriate programmable display 10. The programmable display 10 that has received the screen material stores, for example, the received screen material in its own first memory 11. Alternatively, for example, the screen material determining unit 2 determines whether or not the received screen material is related to the image held in the first memory 11. The surface information is consistent. The presence or absence of the screen data tampering is checked by performing the phase matching/disagreement determination.

Alternatively, for example, the transfer unit 1 of the programmable display 10 will The screen data held in the first memory 11 is transferred to the server device 20. The server device 20 that has received the screen data stores the received screen data in the second memory 21, for example. Alternatively, the screen material determining unit 2 determines whether or not the received screen material matches the screen material held in the second memory 21. By performing the coincidence/disagreement determination, it is checked whether or not the screen data is falsified. Next, the server device 20 notifies the programmable display 10 of the determination result.

The screen material determining unit 2 basically determines that it is held at the first Whether the screen data of the memory 11 matches the screen material held in the second memory 21 is the same. Therefore, as an example, as described above, the screen data held by either of the programmable display 10 and the server device 20 is transferred to the other, thereby comparing the two screen data with each other to determine the phase. Consistent/inconsistent, but not limited to this example. For example, it is also possible to compare the unambiguous check codes (for example, hash values or CRC values) of the corresponding picture data with each other, instead of the picture data, to determine the coincidence/disagreement, thereby making the picture data consistent. / Inconsistent judgment. Of course, when the check codes do not coincide with each other, the screen material held in the first memory 11 does not coincide with the screen data held in the second memory 21.

The motion control unit 12 determines the image data by the above-mentioned screen data. The above-mentioned phase matching/inconsistency determination result obtained by the part 2 (whether or not the tampering is performed), To control the action of the programmable display 10. For example, when the programmable display 10 is activated, the screen data determination unit 2 determines whether or not the tampering is present. As a result, the operation control unit 12 shifts to the error mode when the phase coincidence/disagreement determination at the time of startup is determined to be inconsistent (tampering). In the error mode, for example, an alarm output is performed.

On the other hand, if the above is consistent/inconsistent at startup When it is determined that the determination is the same (no tampering), the operation control unit 12 permits the activation to start the activation process and shifts to the operation mode. In the application mode, the usual processing action is performed. Therefore, the programmable display 10 executes processing such as display or input acceptance of the above-described monitoring/control screen using screen data.

The configuration is performed by the transfer unit 1 The screen data transfer processing between the display device 10 and the server device 20 can not only store the screen data of the programmable display 10 in the server device 20, but also execute the screen data determination unit 2 and the motion control unit 12 described above. Processing.

In addition, the server device 20 may additionally have a display Recording/selection section 22.

The display registration/selection unit 22 makes a new registration of any of the programmable displays 10, for example, as described above. In the above example, an example is shown in which any of the displays is recorded by the drawing device 30 through the network. That is, each of the painting devices 30 typically maintains the screen data of the 1 or a plurality of programmable displays 10 that are managed by each of them, and this remains with respect to the programmable displays 10 Some information (identification ID or IP address, etc.). Accordingly, the display device 30 can transmit the IP address or the like (in addition to the screen material) to the display registration/selection unit 22 of the server device 20 via the external network, thereby enabling the registration request. The registration/selection section 22 memorizes the information.

However, it is not limited to this example. For example, it can also be in the servo In the device device 20, the user or the like performs a new registration operation of the arbitrary programmable display 10 by manual operation (operation of a keyboard or the like/insertion of an external memory). In short, although not specifically illustrated, the server device 20 stores predetermined information on the programmable display 10 to be registered.

Thus, the display registration/selection unit 22 can also have an example. If the registered programmable display 10 is displayed in a list or the like, the user can select the function of the arbitrary programmable display 10. In addition, server device 20 may also execute certain processors with respect to selected programmable display 10. This processing refers to, for example, downloading of screen material, uploading of screen material (backup memory), or checking of tampering of screen material. However, the user may be selected to select a desired processor on the list display screen.

In addition, the server device 20 may additionally have backup control Part 23.

The backup control unit 23 basically acquires the first programmable image display device 10 from any programmable display device 10 (for example, the display registration/selection unit 22 is selected, but is not limited to this example). The picture data of the memory 11, and the picture data is memorized in the second Memory 21. However, in addition to the basic function, it is also possible to confirm whether or not the data acquired by the programmable display 10 is normal, and the function stored in the second memory 21 only when it is normal. For example, even if the screen material itself held in the first memory 11 is normal, there is a possibility that some abnormality occurs due to a communication error or the like, and it is received by the server device 20. The backup control unit 23 confirms that the acquired screen material is not abnormal, and then stores it in the second memory 21.

Therefore, the backup control unit 23 receives any processing by any means. When the screen data of the target display 10 is transmitted, the screen data is temporarily stored in any memory unit other than the second memory 21, and the screen data is folded back to the programmable display 10 of the transmission source and issued. Confirm the requirements consistently.

On the side of the programmable display 10, the system receives the above and is received The screen data judging unit 2 determines whether or not the screen data transferred by the transfer is consistent with the screen data stored in the first memory 11 by the screen data judging unit 2. Then, the determination result is sent back to the server device 20.

Thereby, the backup control unit 23 of the server device 20 is When the result of the return is "consistent", the temporarily stored screen data is stored in the second memory 21. On the other hand, if the result of the return is "inconsistent", the temporarily memorized screen material is discarded. However, the screen material may be acquired again from the programmable display 10 of the processing target. Of course, at this time, the screen information is also returned and the same confirmation request is issued. It is also possible to repeat the process until the phase is obtained. The screen data is stored in the second memory 21 in accordance with the determination of "consistent".

Or, you can roughly memorize the picture data in the second memory. The body 21 is temporarily stored in the memory unit (not shown) instead of the screen data as described above. Thereafter, the transfer screen data is folded back in the same manner as described above, and a coincidence confirmation request is issued. Then, when the result of the return is "inconsistent", the screen data stored in the second memory 21 is erased. In this case, the screen material can be acquired again by the programmable display device 10 to be processed. Of course, at this time, the picture data is also memorized in the second memory 21, and the transfer confirmation request is issued. This process can also be repeated until the determination of "consistent" is obtained. Of course, when the "consistent" determination is obtained, the screen data is kept in the state of being stored in the second memory 21.

As described above, the memory in the second memory 21 is normal. The screen data, and the determination processing of the above-mentioned tampering using the screen data, and the like are also highly reliable.

Further, the server device 20 may be additionally provided with the screen material transfer delivery unit 24. Further, along with this, the drawing device 30 can also have the screen material delivery unit 31.

Here, the painting device 30 will be described first. Painting device 31 also The support function unit 32 shown in the figure is provided. The support function unit 32 itself has an existing function and supports the user's function of creating, editing, and updating arbitrary screen data for any of the programmable displays 10. The new or updated version of the screen data created by the support function unit 32 is downloaded to any of the programmable displays 10 described above. This feature is also an existing feature and is not specifically shown.

Next, the screen material delivery unit 31 described above The created new or updated version of the screen material is delivered to the functional portion of the server device 20 via the network. In this case, information indicating the programmable display 10 suitable for the screen material (the above-mentioned identification ID or IP address, etc.) is also delivered.

The above-described screen material transfer delivery unit 24 of the server device 20 The picture data delivered by the picture material delivery unit 31 is memorized in the second memory 21 and delivered to the appropriate programmable display 10. Thereby, the programmable display 10 memorizes the screen material to be delivered in the first memory 11. However, when the updated version of the screen material is delivered, the old screen material that was originally stored in the second memory 21 or the first memory 11 can be deleted.

However, the screen data transfer delivery unit 24 may be provided with It is substantially the same function as the "function of checking whether or not an abnormality has occurred in the acquired screen data by the communication error or the like" by the backup control unit 23. However, at this time, since the screen data is transferred back to the drawing device 30, it is necessary to have the function of the screen material determining unit 2 in the drawing device 30.

In addition, the server device 20 may additionally have a support function. Part 25.

The support function unit 25 may be the same functional unit as the support function unit 32 of the above-described drawing device 31.

At this time, for example, each time the support function unit 25 creates a new or updated version of the screen data for the executable display unit 10, the server packs The display 20 (for example, the screen material transfer delivery unit 24) stores the created screen data in the second memory 21 and delivers it to the appropriate programmable display 10.

Fig. 2 is an operation example (1) of the above display management system.

First, in this method, basically, the same picture material is stored in both the programmable display 10 and the server device 20 (as long as there is no tampering or the like). Although the operation for this purpose has been described, the following description will be briefly described with reference to FIG. 2 .

As described above, each time the drawing device 30 creates a new picture material (new or updated version), the drawing device 30 delivers the new picture material to the appropriate programmable display 10 or server device 20 and stores it. .

Here, first, a description will be given of a form in which the above-described new screen material is delivered to the appropriate programmable display 10 by the drawing device 30.

At this time, first, the programmable display 10 stores the screen data to be delivered in the first memory 11. On the other hand, the drawing device 30 is, for example, the server device 20, notifying the information (the identification ID or the like) of the programmable display 10 that has delivered the above-mentioned screen data. Alternatively, a new login of the programmable display 10 is performed. Alternatively, the programmable display device 10 to which the new screen material is delivered is notified to the server device 20 of the gist.

Thus, for example, the display registration selection unit 22 has a function of displaying a list of registered programmable displays as described above, but In addition, a list of programmable displays or newly registered programmable displays can be displayed.

Next, for example, when the user selects any programmable display among the programmable displays displayed in the list, the process of backing up the screen data of the selected programmable display is performed. This is performed, for example, by the backup control unit 23 described above, but is not limited to this example. Alternatively, even if the user does not select, the all-programmable display 10 having the screen data update or the like can automatically perform the process of backing up the screen data.

For example, the backup control unit 23 transmits a backup request to the selected programmable display 10 (S1). Thus, the programmable display 10 that has received the backup request transmits the screen data stored in its own first memory 11 to the server device 20 by the transfer unit 1, for example (S2). Of course, at this time, the identification information (identification ID or IP address, etc.) of the display 10 of the transmission source is also transmitted. When receiving the screen material, the server device 20 stores it in its own second memory 21 (S3). In this case, the abnormality check processing (communication error or the like) of the backup control unit 23 may be performed.

However, it is not limited to the above examples. For example, even if the user does not select one by one, the screen data is automatically acquired by the target programmable display device 10 to perform backup memory. Since the programmable display 10 or the newly registered programmable display 10 can be discriminated as described above, the backup request can be automatically transmitted to the programmable displays 10.

As described above, the server device 20 is logged in. When the screen data of the program display 10 is updated, the screen data of the updated version is acquired by the programmable display 10, and the backup is stored in its own second memory 21. Alternatively, if the server device 20 newly registers the programmable display device 10, the screen data is acquired by the programmable display device 10, and the backup is stored in its own second memory 21. As described above, the screen data stored in the first memory 11 is often the same as the screen data stored in the second memory 21 (if there is no tampering or the like).

Next, for the above new screen material by the drawing device 30 The form of delivery to the server device 20 will be described. In this case, the drawing device 30 also transmits the identification information (IP address, etc.) of the display 10 corresponding to the screen material.

At this time, the server device 20 will be the new one delivered as described above. The picture data is stored in its own second memory 21 (S4). Thereafter, the new screen material stored in the second memory 21 is delivered (downloaded) to the appropriate programmable display 10 (S5). Here, this can be done automatically, or the above list display can be performed to enable the user to select, thereby delivering (downloading) to the selected programmable display 10. However, although not described one by one, as described above, in the server device 20, the programmable display 10 having the updated screen data or the programmable display 10 newly registered can be discriminated, so that the programmable display as shown above can be used. 10 list display, or automatic download of new screen data to the programmable display 10 as shown above.

In summary, it is delivered (downloaded) by the server device 20 described above. The programmable display 10 of the new screen material stores the downloaded screen data in its own first memory 11 (S6).

Among them, it is not limited to this example, for example, the above new picture capital The material may be arbitrarily created by the developer or the like by the support function unit 25 on the server device 20. At this time, the server device 20 also stores the new screen material in the second memory 21, and delivers (downloads) it to the appropriate programmable display 10 (S5).

Among them, although they are not described one by one, of course, when communicating, The information indicating the source of the transmission/destination destination, such as the IP address, is also received and sent.

As described above, basically (if there is no tampering or the like), the screen data stored in the first memory 11 is the same as the screen data stored in the second memory 21, and as described below, the image can be checked. Whether the picture material held on the programmable display 10 side has not been tampered with.

The tampering check processing is performed when the programmable display 10 is activated. Or use it at any time/periodically.

When the tampering check processing is started, in the example of FIG. 2, first, the programmable display 10 transmits a determination request to the server device 20 (S7). The server device 20 that has received the determination request transmits a screen material request to the programmable display device 10 of the request source (S8). The programmable display 10 that has received the request for the screen data transmits the screen data stored in its own first memory 11 to the server device 20 (S9).

However, it is not limited to the above examples, and may not be performed. The processing of S7 and S8 described above is replaced by the processing of S9 instead. And the determination request is transmitted, whereby the server device 20 performs the coincidence/disagreement determination regarding the screen material transmitted at S9.

The screen of the determination target is received by the processing of the above S9 The server device 20 of the data performs the determination of the coincidence/disagreement by the own screen data determining unit 2. In other words, the server device 20 (the screen data determining unit 2) compares the received screen data with the screen data held in its own second memory 21 to determine whether the coincidence/disagreement (whether or not there is tampering). . Next, the determination result is sent back to the programmable display 10 (S10).

The programmable display 10 receiving the determination result is by The operation control unit 12 performs an operation in response to the received determination result. For example, when the determination result is OK (consistent; no tampering) in the tampering check processing at the time of starting, the operation control unit 12 permits the activation to start the operation (moving to the operation mode). Further, for example, when the determination result is NG (inconsistent; falsification) in the tampering check processing at the time of starting, the operation control unit 12 does not permit the activation, and moves to, for example, the error mode.

In addition, for example, it is executed at any time/period during use. In the change inspection process, if the determination result is OK (consistent; no tampering), the operation control unit 12 continues to operate as it is. On the other hand, if the result of the determination is NG (inconsistent; there is tampering), the operation control unit 12 stops the operation and moves to, for example, the error mode.

Here, in an exceptional case, the server device 20 is When the second memory 21 has not stored the screen material, the message is sent back to the display 10, or the OK (no tampering) is sent back as a result of the determination. To the display 10. Thereby, the display 10 is forcibly activated in the case of the processing at the time of starting. In this case, the server device 20 may also store the screen data acquired by the display 10 in the second memory 21, but may retransmit the backup request.

However, it is not limited to this example, and may be, for example, in the above S9. In the process, the inspection code corresponding to the screen material is transmitted instead of transmitting the screen material as described above. At this time, the server device 20 (the screen data determining unit 2) determines whether or not the received inspection code matches the inspection code corresponding to the screen material stored in the second storage 21 of the second server 21. Tampering with or not.

3 is an operation example of the above display management system (which is an example) 2).

3 is different from FIG. 2 in that the screen material determining unit 2 is located in the server device 20 in FIG. 2, but is located in the programmable display device 10 in FIG. The operation of FIG. 3 is slightly different from the operation of FIG. 2, but the same operation is also performed. Therefore, only the differences from FIG. 2 will be described below, and the description of the operations similar to those of FIG. 2 will be omitted or simplified.

In Fig. 3, the movement for the determination of the presence or absence of tampering is explained. Work.

In the case of FIG. 3, the programmable display 10 periodically performs determination processing of tampering at the time of startup or during operation. When the processing is started, first, a screen material request is transmitted to the server device 20 (S11). Thereby, the server device 20 (the transfer unit 1) will be stored in its own The screen data of the memory 21 is transferred to the display 10 of the request source (S12).

Thereby, the screen material determination unit 2 of the display 10 executes The screen data stored on the side of the server device 20 and the screen data stored in the first memory 11 of the first device are identical/inconsistent with each other (determination of presence or absence of tampering). Next, the operation control unit 12 of the display 10 executes the operation control of the display 10 in accordance with the determination result (the presence or absence of tampering) obtained by the screen material determination unit 2. Since the reason has been described above, the description is omitted.

In addition, the server device 20 receives the above picture When the material is requested, if there is no screen material in the second memory 21 of its own, the message is sent back to the display 10 of the request source. Thereby, the screen material determination unit 2 of the display 10 is forcibly regarded as having no tampering. Thereby, the operation control unit 12 is permitted to start, in particular, at the time of starting, thereby shifting to the above-described operation mode. Thereby, it is possible to prevent the programmable display 10 from becoming incapable of starting.

In addition, at this time, the server device 20 is immediately formed as The screen data of the display 10 is in a state of backup memory. That is, the server device 20 transmits a backup request to the display 10 of the screen material request source immediately after the request, and the display device 10 that receives the request transmits the screen data stored in the first memory 11 to the server. Device 20. The server device 20 that has received the screen data stores the screen data in its own second memory 21. Of course, at this time, the inspection process by the backup control unit 23 (checking whether or not an abnormality has occurred in the received screen material due to a communication error or the like) may be performed.

The above-mentioned FIG. 2 or FIG. 3 is shown in FIG. 4 to FIG. The action sequence diagram of the processing action.

4 to 8, the programmable display 10 is referred to as "POD10" on the drawing for the sake of simplicity. Similarly, for the sake of simplicity, the server device 20 is referred to as "server 20" on the drawing.

First, the action of the backup action is shown in Figure 4(a). Sequence diagram.

As described above, for example, the display unit 22 may be registered by the display of the server device 20 to display a selection screen or the like (not shown) in which the user can select a desired display. That is, the registered programmable display 10 is displayed in a list on the selection screen, and the user selects an arbitrary display 10. In addition, various commands may be displayed in a list to enable the user to select, for example, a "backup" command or the like.

Thus, on the selection screen, if the user selects the location When the desired programmable display 10 is selected and the "backup" command is selected, the server device 20 transmits the backup request to the selected display 10. However, as described above, the server device 20 is not limited to the above-described example. When the server device 20 is, for example, a newly registered programmable display device 10, it is also possible to transmit a backup request to the display device 10. Alternatively, the server device 20 may transmit a backup request to the display 10 if, for example, the drawing device 30 has a notification that the updated program data is to be delivered to any of the programmable displays 10. Alternatively, as described above, when the tampering determination is made, the backup request may be transmitted if there is no screen material corresponding to the second memory 21 of the user.

The display 10 that receives the above backup request will be remembered The screen data of the first memory 11 of its own is transmitted to the server device 20. The server device 20 stores the received screen data in its own second memory 21. In this case, the "inspection of whether or not the received screen material is normal" is performed, and is stored in the second memory 21 only under normal conditions.

For example, as described above, the login is completed on the server device 20 side. The screen data of each display 10 is stored in the second memory 21 of the server device 20. For example, as described below with reference to FIG. 4(b), the tampering determination may be used, but the present invention is not limited thereto. . For example, if the screen data held on the display 10 side disappears for some reason, the screen data of the backup memory stored in the server device 20 can be downloaded to the display 10 to correspond. In particular, if the painting device 30 is not normally used for some reason, for example, a significant effect is achieved.

Or, if the programmable display 10 fails, it is replaced with In the case of the new programmable display 10, the screen data of the backup memory stored in the server device 20 can also be downloaded to the new display 10. However, at this time, the server device 20 must be notified of the identification information of each of the programmable displays 10 before and after the replacement, for example, by the drawing device 30 beforehand.

In short, each program is stored on the server device 20 side. The screen data of the display 10 is particularly suitable for storing appropriate screen data. Appropriate screen data refers to, for example, an updated version of the (latest version) screen material, or normal screen material, etc. (as described above due to communication errors, etc.) The screen data that is formed as an abnormality is discarded.

The screen data stored on the server device 20 side is used as: ‧ as backup; ‧ used in tampering determination; ‧ downloaded to display 10; any of them is important, and if it occurs on the server device 20 side, it is not saved. When there is a situation with appropriate picture material, the abnormal situation as shown above must be lifted as soon as possible. One example of the processing for this is as described above.

Fig. 4(b) is a view showing the operation sequence at the time of starting.

Here, this corresponds to the sequence of operations of FIG. 2. In other words, the case where the display screen data determination unit 2 is located on the server device 20 side is not limited to this example as described above.

In the programmable display 10, when the user or the like operates the power ON or the reset starts, the display 10 starts the start processing, but first transmits the above determination request to the server device 20. The server device 20 that has received the determination request sends the "screen data request" back to the display 10 in response. Thereby, the display 10 transmits the screen material stored in its own first memory 11 to the server device 10.

Thereby, the server device 20 compares the received screen data with the screen data stored in its own second memory 21 to determine whether or not the two match. Next, the determination result is sent back to the display 10. For example, if the two are consistent, the check OK (no tampering) is sent back to the display 10. If it is not consistent, the NG will be checked. Return) to the display 10.

Therefore, when the display 10 is sent back to check OK, Continue to start the process, and then move to the normal operating state (operating mode) after starting. On the other hand, when the check NG is returned, the start processing is suspended, and the error mode is shifted, and an alarm or the like is output, for example.

As shown above, if there is a possibility of tampering, it is not allowed to display The start of the display 10 itself. When the screen material is tampered with, the programmable display 10 may malfunction, and the external device 100 (the PLC main body or the control target device) may operate abnormally. In this method, the abnormal situation as shown above can be prevented from occurring.

In addition, not only when starting, as shown in Figure 5 (a), (b) In the application, it is also necessary to perform the tampering determination at any time/period, so that even if there is no tampering at the time of starting, and there is tampering during the operation after starting, the situation is immediately detected and the operation is stopped, thereby reducing The possibility of the above abnormal situation.

For example, as shown in FIG. 5(a), the programmable display 10 is, for example, The screen data stored in the first memory 11 of its own is periodically transmitted to the server device 20. In this case, it is preferable to transmit, for example, a predetermined command such as the above-described determination request.

Servo that receives the screen data (and judgment request, etc.) The device device 20 determines whether or not the screen material held on the programmable display unit 10 is falsified by determining whether or not the received screen material matches the screen data stored in the second memory 21 of the second memory 21. Next, the determination result is sent back to the display 10. For example, if the two are consistent, The check OK (no tampering) is sent back to the display 10. If it is inconsistent, the check NG (with tampering) is sent back to the display 10.

If the programmable display 10 is OK, it will be as it is. If the NG is checked, for example, after the operation is stopped, the operation mode is shifted to the error mode to output an alarm.

Consistent/inconsistent determination processing in the above screen data The screen material itself is used in the screen data tampering determination, but is not limited to this example. For example, an unambiguous check code (for example, a hash value or a CRC value, etc.) corresponding to the picture material may also be used.

The use of the above tampering determination process is shown in FIG. 5(b). The sequence of actions for the example of a hash value.

The programmable display 10 periodically transmits the hash value of the screen material held by itself to the server device 20, for example, during operation. In this case, it is preferable to transmit, for example, a predetermined command such as the above-described determination request. Among them, on the display 10 side, the hash value of the screen material is generated every time.

The server device 20 determines whether the received hash value is It is consistent with the hash value of the picture data that you maintain. Here, on the server device 20 side, the hash value of the screen material may be generated every time, but may be generated in advance and memorized.

Next, the server device 20 is consistent if the hash values are the same When the OK (no tampering) is sent back to the display 10, if it is inconsistent, the check NG (with tampering) is sent back to the display 10.

If the programmable display 10 is checked, it will continue to be shipped as it is. When the NG is checked, for example, after the operation is stopped, the operation is shifted to the error mode, and an alarm output or the like is performed.

Among them, a CRC value or the like may be used instead of the hash value.

An example of the overall operation sequence when the above-described hash value is used is shown in FIG.

In the illustrated example, in the server device 20, the display registration unit 22 is selected by the display, and the user selects an arbitrary display 10 to transmit the backup request to the selected display 10. Here, as described above, the backup request is transmitted not limited to the case as shown above, and the description is omitted here.

The display 10 that has received the above backup request transmits the screen data stored in its own first memory 11 to the server device 20. The server device 20 stores the received screen data in its own second memory 21 (here, before, as described above, it is checked whether the received screen data is normal or not, only when it is normal, It is stored in the second memory 21), and the hash value of the received picture data is calculated and stored in a memory or the like. However, although not shown, the display 10 can be notified that the storage of the screen material and the generation and storage of the hash value are completed.

Among them, of course, the coincidence/inconsistency of the hash values means that the picture data is consistent/inconsistent.

Thereafter, the display 10 performs processing for tampering determination at any time/period in the above operation.

In other words, the display 10 periodically reads out the screen material stored in its own first memory 11 during operation, for example, and the screen material is used. The hash value is directly transmitted to the server device 20, or the hash value of the picture data is calculated, and the hash value is transmitted to the server device 20.

Here, if an example in which a hash value is used is described, When receiving the hash value, the server device 20 compares the received hash value with the hash value stored in the memory to determine whether the two match. When the server device 20 matches the hash values, the check OK (the screen data is not falsified) is sent back to the display 10. If the hash values do not match, the check NG (the screen data is falsified) is sent back to the display 10.

The programmable display 10 is as it is when it is checked. If the NG is checked, for example, after the operation is stopped, the operation mode is shifted to the error mode, and an alarm output is performed.

Next, in Figures 7(a) and (b), the display is performed by The operation sequence at the time of the inspection process by the backup control unit 23 is described.

In FIG. 7(a), the server device 20 transmits the backup request to the appropriate programmable display 10 in accordance with some of the triggers described above (eg, by user selection/designation, etc.).

The display 10 that receives the backup request will be stored in The screen data of the own first memory 11 is transmitted to the server device 20. The server device 20 that has received the screen data stores the screen data in its own second memory 21. However, this assumes that the store, not the determined one, is eliminated by checking the results.

Next, the backup control unit 23 executes the above-mentioned inspection office (check if the received picture is due to a communication error, etc.) An abnormality occurred.) Therefore, the backup control unit 23 folds back the received screen data to the display 10 of the transmission source (and also transmits a predetermined command for abnormality detection), and performs coincidence/disagreement determination on the display 10 side. To check for any abnormalities.

a display that receives the above-mentioned picture data that is folded back and transmitted By the screen data determining unit 2, it is determined whether or not the received screen material matches the screen material stored in the first memory 11 of its own. Next, the determination result (OK/NG) is transmitted to the server device 20. Of course, if it is consistent, it becomes OK, and if it is inconsistent, it is NG.

However, it is not limited to this example, for example, the backup control unit 23 A check code corresponding to the received picture material may be generated, and the check code may be folded back to the display 10 of the transmission source. At this time, the display 10 generates a check code corresponding to the screen material stored in the own first memory 11, and determines whether or not the check code is matched with the check code transmitted by the foldback, thereby obtaining the above-described determination result (OK/ NG).

The backup control unit 23 of the server device 20 performs the correspondence The processing of this determination result (OK/NG). That is, when the determination result is NG, the screen material stored in the second memory 21 is erased. Next, as described above, for example, the backup request is transmitted again to the display 10. On the other hand, if the result of the determination is OK, the operation is continued as it is.

In FIG. 7(b), the server device 20 is in accordance with the above These triggers transfer the above backup requirements to the appropriate programmable display 10.

The display 10 that has received the request transmits the screen data stored in its own first memory 11 to the server device 20. The server device 20 that has received the screen data temporarily stores the screen data in a memory or the like (not shown) other than the second memory 21.

Next, the backup control unit 23 executes the above-mentioned inspection office (Check whether the screen data received due to a communication error or the like is abnormal). Therefore, the backup control unit 23 folds back the received screen data to the display 10 of the transmission source (and also transmits a predetermined command for abnormality detection), and performs coincidence/disagreement determination on the display 10 side. To check for any abnormalities.

a display that receives the above-mentioned picture data that is folded back and transmitted Based on the screen data determining unit 2, it is determined whether or not the received screen material matches the screen material stored in its own first memory 11. Next, the determination result (OK/NG) is transmitted to the server device 20.

The backup control unit 23 of the server device 20 performs the correspondence The processing of this determination result (OK/NG). In other words, when the result of the determination is NG, the screen material temporarily stored in the memory (not shown) is discarded. Next, as described above, for example, the backup request is transmitted again to the display 10. On the other hand, when the result of the determination is OK, the screen material temporarily stored in the memory (not shown) is stored in its own second memory 21.

Figure 8 (a) shows the drawing device 30 to the server device 20 The sequence of operations in the form in which the screen material is delivered.

In FIG. 8(a), the drawing device 30 delivers the picture material to the server device 20 each time a certain picture material delivery trigger is generated, that is, through the network. The screen material delivery trigger refers to, for example, a case where the screen data of the new or updated version is created by the programmable display unit 10 managed by the drawing device 30, but is not limited to this example. For example, the programmable display 10 in which the screen material has been created and is in operation can be said to generate a screen material delivery trigger when the server device 20 performs a new registration request.

In short, the picture data about any programmable display 10 When the drawing device 30 is delivered to the server device 20, the server device 20 stores the screen data to be delivered in the second memory 21. The server device 20 additionally transfers/delivers the screen data stored in the second memory 21 to the appropriate programmable display 10. Here, as described above, the drawing device 30 transmits the identification information of the appropriate display 10 and the like together when the screen material is delivered.

The programmable display 10 is received by the server device When the screen data transferred/delivered is 20, the screen data is stored in the first memory 11. Of course, in the programmable display 10, the screen data stored in the first memory 11 at that time is used for operation.

The operation sequence in the form in which the drawing device 30 performs screen data/download on each of the programmable displays 10 is shown in FIG. 8(b).

In FIG. 8(b), the drawing device 30 delivers (downloads) the screen material to an appropriate one each time a certain screen material delivery trigger is generated. Program display 10. Here, the screen material delivery trigger at this time refers to, for example, a case where a new or updated version of the screen material is created with respect to the programmable display 10 managed by the drawing device 30.

The programmable display 10 will be lowered by the painting device 30 The loaded screen data is stored in the first memory 11. Next, the server device 20 can be notified of the update of the existing screen material, etc., but in the illustrated example, the notification is performed by the drawing device 30. The display 10, for example, stores the downloaded screen material in the first memory 11, that is, the notification drawing device 30 is successfully downloaded.

The drawing device 30 is for downloading the screen data to the above After the display 10 is notified, the server device 20 notifies the server device 20 via the network, together with the identification information of the programmable display terminal 10 of the download destination, and the like. The server device 20 that received the notification transmits, for example, the backup request described above to the appropriate programmable display 10. Here, as described above, the appropriate programmable display 10 is the display indicated by the above identification information.

As shown in the above description, the display of the above backup request is received. The display device 10 transmits the screen data stored in the first memory 11 to the server device 20, and the server device 20 stores the received screen data in the second memory 21. Among them, before this, it can be confirmed that there is no abnormality in the screen data.

In addition, as mentioned before, the server device 20 is not necessarily in the office. It is limited to a computer device that is externally connected to an external network such as the Internet (especially remote from the display 10).
