Although details will be described later, the fault value 128 displays the AI signal measurement value at the time of the fault occurrence, and the current value 129 displays the current AI signal measurement value. The cursor value 130 displays the AI signal measurement value at the time indicated by the time cursor 132 displayed on the real-time trend graph 125 only when the check box 131 is turned on. display. The time cursor 132 is manually repositionable on the real-time trend graph 125 .

FIG. 11 shows an example of the DI signal state of the plant equipment as an example of the plant equipment status list 124 displayed in the L-shaped area. The displayed contents are basically the same as those for the AI signal shown in FIG. A different point is that instead of the fault value 128, an occurrence name 133 is provided to indicate the current state of the DI signal (eg, run, stop, fault, etc.). The DI signal shown in FIG. 11 is a signal whose “No” is 2 registered in the registered signal list area 103 of the signal tag definition menu.

When the check box 131 is turned on in the plant equipment status list 124 of FIG. 11(a), a trend graph near the latest time is displayed on the real-time trend graph 125 as shown in FIG. 11(b). In FIG. 11(b), the AI signal is superimposed and displayed, but the trend graph showing the state of the DI signal is shown discretely. As shown in FIG. 11(c), when the check box 131 is turned off, the trend graph is hidden (FIG. 11(d)), and the display of the trend graph can be switched.
In FIG. 11(d), the trend graph of the AI signal with the aforementioned "No" being 1 is displayed. In FIG. 10(b), the trend graph of the DI signal with "No" of 2 is superimposed, and in FIG. 10(d), the trend graph of the AI signal with "No" of 1 is not displayed. A trend graph of the DI signal with "No" of 2 is displayed.

As described above, according to the plant monitoring control device 1 according to the first embodiment, the screen of the display device 10 is divided into the plant monitoring area 121 as the first monitoring area and the It is divided into an area with an L-shaped area 122 which is a second monitoring area. Since the real-time data of the AI signal and the DI signal, which are the acquired plant data, are displayed, the plant monitoring area 121 can be used to mainly monitor the entire plant, while the L-shaped area 122 can be used to monitor the user's experience. Also, it becomes possible to simultaneously monitor the AI signal and DI signal of the specific plant equipment to which attention is desired based on the characteristics of the plant and the real trend graph of the AI signal and DI signal. Even if the specific plant equipment is widely scattered within the plant monitoring area 121, the information of these specific plant equipment can be displayed at different positions in different hierarchies that cannot be displayed on one screen or on multiple monitoring screens. Even if it is in a straddling position, it can be displayed in the L-shaped area 122, and efficient monitoring is possible.
In addition, the L-shaped area 122 is provided with a remarks column 126 area in which notes and manuals regarding the monitoring data can be recorded, and the efficiency of plant monitoring can be improved by sharing monitoring information.

In addition, since it is possible to monitor both the plant monitoring work and the status monitoring of user-defined plant equipment signals, it is also possible to quickly acquire signs of anomalies from the status of specific plant equipment that requires attention displayed in the L-shaped area 122. As a result, it is possible to improve the performance of the plant monitoring control device.
If a skilled observer predefines the specific plant equipment to be noticed displayed in the L-shaped area 122 as a tag of the plant data, the plant monitoring work following the experience of the skilled observer and the user-defined plant equipment signal can be performed. It is also possible to monitor the state of

Furthermore, the screen layout of the plant monitoring area 121 and the L-shaped area 122 can be provided according to the number of AI signal tags and DI signal tags that are defined and registered by the user in advance. Information can be displayed in an appropriate screen layout according to the signal information that the user wants to see and the number thereof, as compared with screen division of a uniform size such as division. This allows for more efficient plant monitoring.

In the above description, the number of signal tags is described as being 1 to 8 at maximum and 9 to 16 at maximum. For example, the number of signal tags is divided into 4 levels, from 1 to 4 points, 5 to 8 points, 9 to 12 points, and 13 to 16 points, and 4 types of screen layouts are prepared. good too.
A plurality of screen layouts may be prepared according to the complexity of the plant monitoring area 121 even if the screen layouts have the same maximum number of points.
In either case, the information can be displayed in an appropriate screen layout according to the signal information and the number of signals that the user wants to see, enabling more efficient plant monitoring.

Embodiment 3.
A plant monitoring control device according to Embodiment 3 will be described below with reference to the drawings.
The plant monitoring and controlling apparatus 1 according to the third embodiment has the same general configuration as those of the first and second embodiments, but receives a "state change notification" from the controller 2 via the control bus 3, and receives a "state change notification". It is different in that it has a function corresponding to "change notification".

FIG. 14 is a diagram showing the configuration of the screen data storage unit 23 of the control unit 20 of the plant monitoring control device 1 according to Embodiment 3. The screen data storage unit 23 further includes a state change data management unit 233 . The state change data management unit 233 determines whether or not a “state change notification” received from the controller 2 via the control bus 3 is received. The term "status change" as used herein means a change in the state of plant equipment, and means, for example, a transition from a normal state to a failure state, or a transition from a failure state to a recovery state. The state change data management unit 233 also has state change history data including AI failure alarm data 233a, DI failure alarm data 233b, AI recovery alarm data 233c, DI recovery alarm data 233d, and AI failure value 233e.

When a failure occurs in the AI signal and the DI signal (the failure includes an abnormality), the status change data management unit 233 stores the signal tag definition data managed by the L-shaped area display data management unit 231. 231a to generate and save AI failure alarm data 233a or DI failure alarm data 233b linked to the user-defined signal tag.

In addition, when a failure occurs in the AI signal, the state change data management unit 233 requests the plant data management unit 232 to send an AI failure value 233e, which is an AI signal measurement value at the time of failure associated with the user-defined AI signal tag. and get.

When the failed AI and DI signals are recovered, the state change data management unit 233 refers to the signal tag definition data 231a managed by the L-shaped area display data management unit 231, and converts the signal tag to the user-defined signal tag. The associated AI recovery alarm data 233c or DI recovery alarm data 233d is generated and saved.

Next, a procedure for displaying the information in the L-shaped area of the display device 10 when the "state change notification" is received by the state change data management unit 233 will be described with reference to FIG.

When the state change notification 40 is received, it is determined whether the AI signal and the DI signal are "failure" (transition from normal state to failure state) or "recovery" (transition from failure state to recovery state) (step S302). ). If the status change notification 40 has not been received (No in step S302), the process ends.

In the case of "failure" in step S302, the state change data management unit 233 refers to the signal tag definition data 231a managed by the L-shaped area display data management unit 231, and the AI linked to the user-defined AI signal tag and DI signal tag. Failure alarm data 233a or DI failure alarm data 233b is generated and stored (step S303). Further, when a “failure” occurs in the AI signal, the state change data management unit 233 puts an AI failure value 233e, which is an AI signal measurement value at the time of failure associated with the user-defined AI signal tag, into the plant data management unit. 232 from the plant data managed and stored (step S404). The saved AI failure alarm data 233a, DI failure alarm data 233b, and AI failure value 233e are sent to the screen display management unit 24 (steps S305 and S306) and displayed in the plant equipment status list 124 in the L-shaped area 122.
