Reference numeral 5 is a processing task for monitoring / controlling a monitoring control target such as the plant 8. Further, 6 is a processing means constituted by the display / operation means 2, the dynamic attribute acquisition / change means 4 and the processing task 5. 7 is a display, the operation means 2 is a display,
A memory amount information holding unit for holding the display / operation attribute 31 read from the operation attribute holding unit 3 and the memory amount information 71 to be secured according to the type of the operation component 9, 8 is a plant to be monitored and controlled, Reference numeral 9 is a display / operation component in which information necessary for display on the CRT display 11 and transmission of events and commands is collected as one functional module as its attributes. Here, the display / operation component 9 is displayed on the CRT display 11 and is operated by pressing the touch panel 12.

Next, the operation will be described. FIG. 2 is a flow chart showing the flow of processing when the plant monitoring control device is activated, and FIG.
It is explanatory drawing which reads an operation attribute. When the plant monitoring control device is activated, the display / operation means 2 reads the display / operation attribute 31 held in the display / operation attribute holding means 3 (S
1). The display / operation means 2 copies the memory amount information 71 held in the memory amount information holding means 7 (S2). The display / operation means 2 secures the memory 21 based on the display / operation attribute 31 and the memory amount information 71. Then, the display / operation attribute 31 is stored in the secured memory 21 (S
3). The display / operation means 2 outputs a display signal corresponding to the display / operation attribute 22 corresponding to the first screen from the display / operation attribute 22 stored in the memory 21 to the CRT display 11 (S4). When the display of the first screen is completed, the display / operation means 2 is in a waiting state for an input event from the operator input / output device 1 or the processing task 5 (S5).

Here, the display / operation attributes 31 of S2 and S3
Will be described with reference to FIG. In FIG. 3, 21 is a memory secured by the display / operation means 2 according to the display / operation attribute 31 and the memory amount information 71, and 22 is a display / operation attribute stored in the memory 21. 31a-
Reference numeral 31x indicates the attribute value of the display / operation component 9 for one screen displayed on the CRT display 11. For example, the display / operation attribute 31a corresponds to the attribute value of the display / operation component 9 forming the first screen. In this case, the first image 31a
Are display / operation parts A1, A2, A3, B1, C1 ...
-It is composed of P4. And display / operation parts A1
As for the attribute value of, the color is a1, the position is b4, the display character is c3, and the operation command is r1. Also, the memory amount information 71
Determines a predetermined memory amount to be secured for each type of display / operation parts A to P. For example, display / operation part A
, The color is 4 bytes, the position is 4 bytes, the display character is 16 bytes, ..., The operation command is 16 bytes, and the memory amount to be secured is determined. That is, the memory amount to be secured is determined by the type of the display / operation component 9 and the memory amount information 71 included in the display / operation attribute 31. Then, based on this information, the display / operation means 2 secures the memory 21, and stores the display / operation attribute 31 in the memory 21. Further, the amount of memory for storing the supervisory control status of the plant 8 is also determined according to the type of each display / operation component 9.

Here, the display attribute is the appearance determined by the display / operation attribute such as the position, color, and display character string of the display / operation component 9 displayed on the CRT display 11. This corresponds not only to the display / operation attribute 22 (corresponding to the display / operation attribute 31a) of the displayed first screen, but also to the display / operation attribute 22 (display / operation attribute 31b to 31x) of the screen not currently displayed. ) Is also determined. The operation attribute relates to the transmission of a command or an event output when the display / operation component 9 is pressed.
That is, from the touch panel 12 or the like, the display / operation component 9
When is pressed, the operation of the display / operation component 9 such as what command or event is to be sent and where is determined. Further, the display / operation means 2 has a memory 21 which dynamically stores the display / operation attribute 22 of the display / operation component 9 inside the display / operation means 2. The display / operation attribute 22 stored in the memory 21 is used to check the stored position of each display / operation attribute 22 when the display / operation attribute 22 is changed or acquired. For example, the dynamic attribute acquisition / modification unit 4 uses the display / operation component A2.
A case will be described in which the display / operation attribute 22 regarding the display character of is to be changed. In order to change the display / operation attribute 22 related to the display character, the dynamic attribute acquisition / change means 4 knows which part of the display / operation attribute 22 the display / operation attribute 22 is in. There is a need. It can be seen from the memory amount information 71 that this display / operation attribute 22 is the third display / operation attribute 22 from the front. Since the storage position of the display / operation attribute 22 is known, the dynamic attribute acquisition / change unit 4 can change the display / operation attribute 22 of the portion.

Next, the event input from the operator input / output device 1 (S6) and the event input from the processing task 5 (S7) will be described separately. FIG. 4 is an explanatory diagram of event input (S6) from the operator input / output device 1. In FIG. 4, the operation of inputting an input event from the operator input / output device 1 will be described. When the operator presses the operation display component 9 on the touch panel 12, the output signal is
It is input to the display / operation means 2. The display / operation means 2 reads an operation command corresponding to the display / operation component 9 from the memory 21 (T1). Whether the display / operation means 2 requests acquisition of the display / operation attribute 22 for the display / operation component 9 based on the operation attribute (event) read from the memory 21.
It is determined whether the display / operation attribute 9 for the display / operation component 9 is requested to be changed, the processing for the processing task 5 is requested, or any other. Then, the display / operation means 2 sends an event to an appropriate destination based on the determination (T2). If the event requires acquisition of the display / operation attribute 22, the event is sent to the dynamic attribute acquisition / change means 4 (T3). Upon receiving the event, the dynamic attribute acquisition / modification unit 4 acquires the display / operation attribute 22 stored in the memory 21 (T4). The display / operation means 2 displays the display / operation acquired by the dynamic attribute acquisition / change means 4.
A signal according to the operation attribute 22 is output to the CRT display 11. (T5). If the event is a request to change the display / operation attribute 22, the event is sent to the dynamic attribute acquisition / change means 4 (T6). Upon receiving the event, the dynamic attribute acquisition / modification unit 4 modifies the display / operation attribute 22 stored in the memory 21 (T7). Display / operation means 2
Outputs a signal corresponding to the display / operation attribute 22 changed by the dynamic attribute acquisition / change means 4 to the CRT display 11. The screen or the like is updated based on the change in the display / operation attribute 22 (T8). If the type of event requires an operation to the processing task 5, the display / operation means 2 is the processing task 5.
(T9). The processing task 5 acquires the control information of the plant 8 included in the function attribute of the display / operation attribute 22, and controls the plant 8 according to the information (T1
0). As described above, the processing (T
When 1) is completed, the display / operation means 2 enters the input event waiting state again (T13).

Next, processing of an input event from the processing task 5 will be described. FIG. 5 is a flowchart showing processing of an input event from a processing task. An event is input from the processing task 5 (U1). First, the case where the input event acquires the display / operation attribute 22 will be described. The input event from the processing task 5 is directly input to the dynamic attribute acquisition / change means 4 (U2). Upon receiving the input event, the dynamic attribute acquisition / modification unit 4 checks the type and determines the operation. When the input event is to acquire the display / operation attribute 22, the target display / operation attribute 22 is acquired from the memory 21 (U
3). The dynamic attribute acquisition / modification unit 4 returns the acquired display / operation attribute 22 to the processing task 5 (U4). Next,
An input event that changes the display / operation attribute 22 will be described. The input event from the processing task 5 is directly input to the dynamic attribute acquisition / change means 4 (U5). When the input event is to change the display / operation attribute 22, the display / operation attribute 22 stored in the memory 21 is changed (U6). The dynamic attribute acquisition / modification unit 4 returns the modified display / operation attribute 22 to the processing task 5 (U
7). When the processing of the input event is completed, the display / operation means 2 again enters the event waiting state (U8).

A specific example of the above processing will be described with reference to the block diagram of FIG. 6 and the flowchart of FIG. For example,
The operator wants to see a screen to know the current supervisory control status of the plant 8. The operator selects a display / operation component 9 having a desired function from the display / operation components 9 displayed on the screen and operates the display / operation component 9. That is, the touch panel 12 showing the monitor control screen display button of the display / operation components 9 is pressed (V1). Operation part 9
The display / operation means 2 that receives as a event that the button has been pressed determines the destination of the event and the operation content based on the display / operation attribute 22 stored in the memory 21 for this display / operation component 9 (V2). . The display / operation means 2 checks the destination of this event and sends the information to the processing task 5 (V3). The processing task 5 receiving this information checks the current state of the plant 8 according to the content (V4). Then, the processing task 5 requests the dynamic attribute acquisition / change means 4 to change the display / operation attribute 22 in order to display the monitoring control information of the plant 8 (V
5). Dynamic attribute acquisition / modification means 4 receiving this request
Is a display / operation attribute 22 stored in the memory 21.
Is changed according to the supervisory control state of the plant 8. Then, the display / operation means 2 outputs a display signal associated with the change of the display / operation attribute 22 to the CRT display 11 (V6). Then, the change of the display / operation attribute 22 made can be understood by the operator through a CRT display or the like. That is, the operator is the current plant 8
You can know the state of.

Next, a case where the display / operation attribute 31 has a specification change will be described. It is assumed that there is a change in the specifications of the display screen and it is necessary to change the display.
At this time, conventionally, it was necessary to stop the plant monitoring control device and change the programs related to the display / operation attributes 31a to 31x on the display screen. FIG. 8 is an explanatory diagram of a plant monitoring control apparatus that changes display / operation attributes and changes specifications by another computer apparatus. In FIG. 8, 40 is a plant monitoring control device, 41 is a computer device existing separately from the plant monitoring control device 40, 4
2 is a plant monitoring control device 40 and a computer device 41
To connect a LAN, 35 is a new display and operating attributes corresponding to the specification change. The display / operation attribute 35 for initializing the display / operation component 9 is created by the computer device 41. This work is easy because you can create it while looking at the finished image on the screen. Then, the display / operation attribute 35 is transferred from the computer device 41 to the plant monitoring control device 40 via the LAN 42. Therefore, the display / operation attribute 31 held in the display / operation attribute holding means 3 of the plant monitoring control device 40 holds a new display / operation attribute 35. After that, the operator
Re-reading of operation attribute 35 or plant monitoring control device 4
The display screen is changed by instructing to restart 0. That is, the operator presses the display / operation component 9 whose operation attribute is that the processing means 6 restarts the plant monitoring control device 40 or reloads the display / operation attribute 35. Then,
The display / operation means 2 that has received the reread command reads the display / operation attribute 35 and updates the display / operation attribute 22. In the above description, the case where the changed display / operation attribute 35 is all attributes has been described. However, when the display / operation attribute 31 to be changed is only a specific screen, the display / operation attribute 35 corresponding to the screen is changed to another computer device 41.
Create with. Then, the display / operation means 2 may read the display / operation attribute 35 corresponding to a specific screen to correspond to the specification change.

As described above, the display of the processing means 6
The operation means 2 checks how to set the read display / operation attribute 31 based on the memory amount information 71. Next, the display of the set display / operation component 9
The memory 21 for storing the operation attribute 31 is secured, and the setting of the display / operation attribute 31 is stored in the memory 21. With this configuration, it is possible to deal with changes in specifications. That is, since the display / operation attribute 31 is not implemented as logic, the display / operation attribute 31 may be changed and the changed display / operation attribute 31 may be stored in the memory 21 again. Therefore, even if the specification of the display / operation attribute 31 is changed, the plant monitoring control device is not stopped, or when it is stopped, it can be dealt with only by the read time of the changed display / operation attribute 31. Furthermore, when the changed display / operation attribute 31 is read only on the screen that requires a specific specification change, the reading time can be further shortened. Further, since the storage information of the display / operation attribute 22 is determined by the memory amount information 71 and the dynamic attribute acquisition / change means 4 is provided, the dynamic change of the display / operation attribute 22 stops the plant monitoring control device. It is possible without. Furthermore, the display / operation attribute 31 of the display / operation component 9
However, it is easy to describe because it can be described by a clearly defined specification description language (language grammatical definition and text data). Furthermore, while observing the actual configuration on the CRT display, the display / operation attribute 31 on the first screen is displayed.
It will be possible to create. Therefore, development cost and development period can be reduced.

Example 2. Another embodiment of the present invention will be described below. Figure 9
FIG. 3 is a block diagram showing a configuration of a plant monitoring control device according to the present invention. In FIG. 9, reference numeral 15 is a control attribute holding means for holding the control attribute 151 for controlling the plant 8 which is read by the display / operation means 2 at the time of startup. The other configuration except that the control attribute 151 is not implemented in the logic is the same as that of the first embodiment.

Next, the operation will be described. When the plant monitoring control device is activated, the display / operation means 2 reads the display / operation attribute 31 held in the display / operation attribute holding means 3 and the control attribute 151 held in the control attribute holding means 15. The display / operation means 2 copies the memory amount information 71 held in the memory amount information holding means 7. The display / operation means 2 secures the memory 21 based on the display / operation attribute 31, the control attribute 151, and the memory amount information 71. Then, the display / operation attribute 31 and the control attribute 151 are stored in the secured memory 21. The display / operation means 2 is a memory 2
The display signal corresponding to the display / operation attribute 22 corresponding to the first screen stored in 1 is output to the CRT display 11, and the control command of the plant 8 is output according to the control attribute 22 stored in the memory 21. Display when the first screen is displayed
The operation means 2 is in a state of waiting for an input event from the operator input / output device 1 or the processing task 5. Thereafter, the plant 8 is controlled based on the event input from the operator input / output device 1 or the processing task 5. Here, the method of storing the control attribute 151 in the memory 21 is the same as the method of storing the display / operation attribute 31 in the memory 21. That is, the memory amount information 71 determines a predetermined memory amount according to the type of each control command.

As described above, since it is configured as described above, it is possible to cope with a specification change. In other words, display
Since the operation attribute 31 and the control attribute 151 are not implemented as logic, the control attribute 151 may be changed and the changed control attribute 151 may be stored in the memory 21 again. Therefore, even when the specification of the control attribute 151 is changed, the plant monitoring control device is not stopped, or when it is stopped, it can be dealt with only by the read time of the changed control attribute 31. Further, since the storage information of the display / operation attribute 22 is determined by the memory amount information 71 and the dynamic attribute acquisition / change means 4 is provided, the dynamic change of the display / operation attribute and the control attribute 22 causes the plant monitoring control device. It is possible without stopping. Further, since the control attribute 151 can be described in a clearly defined specification description language, the description is easy. Furthermore, it becomes possible to create the control attribute 151 on the CRT display.
Therefore, development cost and development period can be reduced.
