In DCS, the control device is connected to, for example, an HMI (Human Machine Interface) and an information processing server by a LAN (Local Area Network). The control device transmits various information collected from the equipment to, for example, an HMI and / or an information processing server via a LAN.

The information processing server stores, for example, various information transmitted from the control device as historical data. The observer of the plant or the like displays the history data on the HMI monitoring screen when operating the equipment or when an abnormality occurs in the equipment. When the information processing server is requested to browse the history data by the HMI, the information processing server expands the stored history data to the HMI requested to browse.

By the way, depending on the specifications of the distributed control system, for example, it is possible to correct the information set for the equipment in the historical data from the HMI. Such corrections are shared by the entire distributed control system provided at the airport, and information reflecting the corrections is accumulated in the historical data. In this way, for example, if the information corrected by one HMI is shared by the entire system, the observer who uses the HMI unrelated to the correction may misidentify the historical data.

The history creation unit 1512 creates a history file in a format corresponding to a preset display application based on the value included in the item data and the read name (step S34). The history creation unit 1512 sets the file name of the created history file as, for example, a file name using the year, month, day, hour, minute, and second at the time of creation. The history creation unit 1512 stores the created history file as history data 1523 in the storage unit 152.

Next, an operation in which the history editing device 15 displays the history information about the history data 1523 on the display 154 will be described.
FIG. 4 is a flowchart showing an example of an operation in which the history editing device 15 shown in FIG. 2 displays history information about the history data 1523 on the display 154. When the operator of the history editing device 15 wants to check the latest history information, he / she inputs a display instruction for the history file via the input unit 153.

Specifically, for example, the operator presses a display icon indicating that history information is displayed. When the display icon is pressed, the history display unit 1513 displays, for example, a display dialog on the display 154. The display target date is displayed in the display dialog. The display target date represents, for example, the date when the latest history file was created. When the operator wants to display the history file of the displayed date, the operator executes the display of this history file.

The history display unit 1513 determines whether or not there is a display instruction from the operator (step S41). When there is a display instruction (Yes in step S41), the history display unit 1513 reads the history file with the latest date from the storage unit 152. The history display unit 1513 displays the read history file on the display 154 (step S42).

The same history file may be set so that it cannot be accessed at the same time. For example, suppose that a display instruction for this history file is input while history information about a predetermined history file is being displayed. The history display unit 1513 displays an error dialog on the display 154, for example, in response to another display instruction for the history file being displayed.

Next, an operation in which the history editing device 15 edits the history information displayed on the display 154 will be described.
FIG. 6 is a flowchart showing an example of an operation in which the history editing device 15 shown in FIG. 2 edits the history information displayed on the display 154. When the operator of the history editing device 15 wants to edit the history information displayed on the display 154, he / she selects the value to be edited via the input unit 153. The operator changes the selected value to a desired value.

The editorial unit 1514 determines whether or not there is a change instruction from the operator, for example, whether or not the value has been changed by the operator (step S61). When there is a change instruction (Yes in step S61), the editorial unit 1514 changes the value of the history information based on the input from the operator (step S62). At this time, the editorial unit 1514 may display the changed value so as to be distinguishable from other values. For example, the editorial unit 1514 displays the changed value in a color different from other values.

When confirming the changed value, the operator takes a procedure for confirming it. For example, the operator presses the save button for the history file.

The editorial unit 1514 determines whether or not the change has been confirmed, for example, whether or not the save button of the history file has been pressed by the operator (step S63). When the change is confirmed (Yes in step S63), the editorial unit 1514 updates the history file so as to include the changed content. At this time, the history file is updated while the identification display for the changed value displayed identifiable is maintained.

FIG. 7 is a diagram showing an example of history information in which some values have been changed. In FIG. 7, the PU name: "system shutdown" at the time: "2019/2/16 21:31", which was shown in FIG. 5, is the PU name: "system shutdown to carry out inspection", and the operation content. : It has been changed to "Implemented by charge A". In addition, the PU name: "system startup" at the time: "2019/2/17 9:14" has been changed to the PU name: "system startup because the inspection has been completed", and the operation content: "executed by charge B". There is. The changed part is displayed in red, for example.

FIG. 8 is a flowchart showing an example of an operation in which the history editing device 15 shown in FIG. 2 updates the name data 1221 or the filing data 1222 managed by the information processing server 12 based on the edited history data 1523. .. When the operator of the history editing device 15 wants to update the name data 1221 or the filing data 1222 managed by the information processing server 12 based on the edited history file, the operator takes a procedure for updating via the input unit 153.

Specifically, for example, the operator presses the update icon to update the name data 1221 or the filing data 1222 of the information processing server 12.

The update unit 1515 determines whether or not an update instruction has been given by the operator, for example, whether or not the update icon has been pressed by the operator (step S81). When the update unit 1515 receives an update instruction (Yes in step S81), the update unit 1515 creates update data for the changed portion and transmits an update signal including the created update data to the information processing server 12 (step S82). Note that the update data may be created based not only on the changed part but also on the entire history file in which the change has been made.

When the update unit 1213 of the information processing server 12 receives the update signal transmitted from the history editing device 15, the name included in the name data 1221 or the PV included in the filing data 1222 is based on the update data included in the update signal. Change data, DI data, SU data, DO data, and AO data. That is, according to the example shown in FIG. 7, even in the filing data 1222, the PU name: "system termination" at the time: "2019/2/16 21:31" is changed to the PU name: "to carry out the inspection. "System shutdown", operation content: changed to "Implemented by charge A", PU name: "System startup" at time: "2019/2/17 9:14", PU name: "System startup because inspection is completed" , Operation content: "Implemented by charge B" is changed. When the update unit 1213 updates the name data 1221 or the filing data 1222, the update unit 1213 transmits an end signal indicating that the update has been completed to the history editing device 15.

The update unit 1515 of the history editing device 15 determines whether or not the end signal transmitted from the information processing server 12 has been received (step S83). When the end signal is received (Yes in step S83), the update unit 1515 changes the display mode of the changed portion in the history information (step S84). For example, the update unit 1515 changes the value displayed in red to display in green in response to the end signal.

It should be noted that special authority may be required to update the history information to the name data 1221 or the filing data 1222 managed by the information processing server 12. For example, when the update icon is pressed, the update unit 1515 confirms whether or not the operator who pressed the icon has authority based on the login information. If the operator has the authority, the update unit 1515 executes the processes after step S82 on the assumption that the update instruction has been given.

Next, the operation in which the history editing device 15 prints the history data 1523 will be described.
For example, the operator presses a print icon to print the history information. When the print icon is pressed, the output control unit 1516 displays, for example, a print dialog on the display 154. The print target period is displayed in the print dialog. For example, the date when the latest history file was created is displayed at the start and end of the print target period. When the operator desires to print the history data 1523 for the displayed period, the operator causes the printing to be executed.

If the history file does not exist in the history data 1523, the output control unit 1516 displays an error dialog on the display 154 as a print failure.

Further, the execution of printing is not limited to the one triggered by the instruction of the operator. The output control unit 1516 may execute printing at a preset time. Specifically, for example, the operator registers the printing time via the input unit 153. At the registered time, the output control unit 1516 prints, for example, the history file created on the previous day. If the printing for the current day has already been executed according to the instruction of the operator, the printing may not be executed.

As described above, in the above embodiment, the history editing device 15 collects the item data managed by the information processing server 12 by the collecting unit 1511. Then, the history editing device 15 creates the history data 1523 in a format corresponding to the display application different from the display application used in the first HMI 11 and the second HMI 14 based on the collected item data by the history creation unit 1512. I have to. As a result, the history editing device 15 can create the history data 1523 unique to the device at a location independent of the filing data 1522 managed by the information processing server 12.

Further, in the above embodiment, the history editing device 15 causes the history display unit 1513 to display the history information about the created history data 1523 on the display 154. As a result, it is possible to display the independently created history data 1523 on the display 154 in addition to the filing data 1522 managed by the information processing server 12.

Further, in the above embodiment, the history editing device 15 is configured by the editing unit 1514 to change at least a part of the history information displayed on the display 154. As a result, apart from the filing data 1522 managed by the information processing server 12, only the history data 1523 originally created can be edited.

In the conventional monitoring and control system, for example, when inspecting the equipment at the site, a simulated operation is performed, so that the history of the simulated operation is displayed on the monitoring screen of the HMI. However, if the display is as it is, it is difficult to determine at a later date whether the history of inspecting the equipment is the history of the simulated operation or the history of the actual operation. Therefore, if, for example, the equipment name of this history is changed to "pump (inspection)" and the operation content is changed to "simulated operation" on the monitoring screen, the changed content will be applied to the entire monitoring and control system thereafter. .. Therefore, even if the inspection is completed, if the change is not returned, the change will continue to be displayed. In this way, if you forget to change the original name, the observer will judge that you are inspecting, and there is a possibility of erroneous operation on the monitoring screen.

In the history editing device 15 according to the present embodiment, changes to the history data 1523 are closed in the history editing device 15 unless a predetermined procedure is performed. Therefore, changes to the history data 1523 are not applied to the entire monitoring and control system. Therefore, even if the operator of the history editing device 15 inspects the equipment via the history editing device 15 and changes the history data for this inspection to the operator's own name, the observer who uses the HMI. Cannot confirm the changed name.

Further, in the above embodiment, the history editing device 15 causes the updating unit 1515 to update the name data 1221 or the filing data 1222 managed by the information processing server 12 based on the edited history data. As a result, the history data 1523 created by the history editing device 15 can be applied to the entire monitoring and control system 1 as needed.

Therefore, according to the history editing device 15 according to the present embodiment, the history data can be managed while avoiding sharing in the entire system.
