FIG. 4 shows an example of processing executed by the screen processing means 3 when the plant monitoring means 2 notifies a monitoring point where an abnormality has occurred.

The screen processing means 3 first initializes the value of the counter l to 1 (processing 101), and then displays the system monitoring screen A of the
Process 102) to take out m from the monitoring screen storage means l and check whether the monitoring point (alarm point) S notified by the plant monitoring means 2 is included in the display contents of the system monitoring screen A. is included in the system monitoring screen Am (determination 103).

When the result of judgment 103 is NO, the counter m is incremented (process 104), and it is checked whether the value of the counter is larger than the number Amax of grid monitoring screens Am (judgment 105), and the result of judgment 105 is NO. If so, the process returns to step 102 to check the primary system monitoring screen Am.

Also, the result of judgment 103 is WE! When it becomes S, it is checked whether the alarm point table VPT in which the identification information of the system monitoring screen Am is set to the value of the system diagram screen number ND is registered in the monitoring screen registration means 4 (judgment 106). When the result of step 106 is YES, the double registration flag F of the system screen registration table WPT is
D is set (process 107). Further, when the result of determination 106 is No, processing 107 is not executed.

Then, the alarm point X notified at that time is set in the alarm point information IiP, the double registration flag FD is reset, the identification information of the system monitoring screen Am is set in the system diagram screen number ND, and the monitoring pattern registration pointer is set. Data indicating the beginning of the empty area of the monitoring pattern display registration means 5 at that time is set in PP, and the alarm point table WPT is created.
and create a new alarm point table 1ilPT.
is registered in the free space of the monitoring screen registration means 4 (process 10
8).

Next, trend graph monitoring screen registration processing 109 extracts all trend graph monitoring screens whose display contents include alarm point X, and logic monitoring screen registration processing 1 extracts all logic monitoring screens whose display contents contain alarm point X.

When the result of the judgment 109f is YES, since the processing for all trend graph monitoring screens Bj has been completed, the trend graph monitoring screen registration process 109 is ended and the process moves to the logic monitoring screen registration process 110.

Further, the contents of the logic monitoring screen registration process 110 and the group trend monitoring screen registration process 111 are almost the same as the trend graph monitoring screen registration process 109.

Further, when the result of the first judgment 105 is YES, this process is immediately terminated.

For example, when alarm points c, b, and a become abnormal in sequence, alarm point tables WPTa, VPTb, and WPTc corresponding to each are formed as shown in FIG. 5, and the monitoring screen registration means 4 At the same time, the trend graph monitoring screen, logic monitoring screen, and group trend monitoring screen including each alarm point a, b, and c are all extracted, and a monitoring pattern is displayed for each alarm point a, b, and c. It is registered in consecutive areas GPa, GPb, and GPc of the registration means 5.

In this case, alarm point a is included in system # monitoring screen Aa, and three trend graph monitoring screens Bjao, Bja
1. Bjaz, 1 logic monitoring screen 8kaa, and 2 group trend monitoring screens BQao, BQa
Each is included in the display contents of x.

In addition, alarm point b is included in the system monitoring screen ABC, and is included in the display contents of one trend graph monitoring screen Bjbo, two logic monitoring screens Bkbo and Bkbx, and one group trend monitoring screen BQba. .

In addition, the alarm point C is included in the system monitoring screen ABC, and is included in the display contents of one trend graph monitoring screen Bjco, one logic monitoring screen Bkco, Bkc1, and two group trend monitoring screens B11ca, BQct. ing.

Furthermore, in this case, before the alarm point b becomes abnormal, the alarm point C is in the abnormal state, and the alarm point table WPTc has already been formed and registered in the monitoring screen registration means 4, so the alarm Point table 1I
Dual registration flag FD of PTc is set (data “1”)
”) is set. Other alarm points a, b
alarm point table WPTa.

The double registration flags FD of the vP units are each set to a reset state (data "0").

In this way, when an alarm point is notified from the plant monitoring means 2 to the screen processing means 3, an alarm point table VPT regarding the alarm point is formed and newly registered in the monitoring screen registration means 4, and the alarm When the identification information of the system drawing in which points are displayed is already registered in another alarm point table WPT, the double registration flag F of the other alarm point table WPT
il is set. At the same time, all trend graph monitoring screens, logic monitoring screens, and group trend monitoring screens that include alarm points in their display contents are extracted and placed in the continuous area of the monitoring pattern display registration means 5 associated with the alarm point table WPT. be registered.

Figure 6 shows the alarm return point X from the plant monitoring means 2.
An example of processing executed by the screen processing means 3 when notified is shown.

First, the counter y is initialized to 1 (201), and the alarm return point is set (process 202, judgment 2
03).

When the alarm return point X is not included in the alarm point table VPTy and the result of judgment 203 is NO,
The counter y is incremented (step 204), and it is checked whether the value of the counter y exceeds the number registered in the alarm point table 1ilPT (determination 205). Judgment 205
When the result is NO, the process returns to step 202 to check the next alarm point table 1ilPT.

If the result of judgment 203 is YI2S, the alarm point table w containing the alarm return point
pry and its alarm point table l1PTV
The information in the registration area of the monitoring pattern display registration means 5 related to is deleted (process 206).

Then, it is checked whether the double registration flag FD of the deleted alarm point table WPTy is set (judgment 207), and when the result of determination 207 is NO, the deleted An alarm point table υ that has a system drawing number NO with the same content as the system drawing number NO of the alarm point table wpTy.
Check whether there is a PT and reset the double registration flag FD of the first found alarm point table WPT (processes 208, 209, judgment 210, process 211
, judgment 212, processing 213).

Further, when the result of determination 205 is YES, and
If the result of determination 207 is YES, this process is immediately terminated.

Therefore, for example, in the state shown in FIG.
If the alarm returns, the alarm point table wpT
b and area GPb are deleted from the monitoring screen registration means 4 and the monitoring pattern display registration means 5, respectively, and the alarm point table VPTC has the same system drawing number ND as the system drawing number NO of the alarm point table wpTb. , the double registration flag FD is reset.

In this way, the alarm point table WPT of the point where the alarm has returned, and the alarm point table W
The information on the trend graph monitoring screen, logic monitoring screen, and group trend monitoring screen registered in the monitoring pattern display registration means 5 in association with the PT is deleted.

With the above configuration, alarm point h +g+Le+d+Ct
It is assumed that b*a goes into an abnormal state in this order, and display data for alarm points a, b, and c are stored in the monitoring pattern display registration means 5, respectively, as shown in FIG.

At this time, the display control means 6 takes out the alarm point tables registered in the monitoring screen registration means 4 in order from the newest one, removes duplicates, and creates a system monitoring screen as shown in FIG. 7(a). Like, split screen DSI, DS2
．． DS3. They are placed on the DS4 and displayed on the CRT7. At this time, process signals to be displayed on each system monitoring screen are appropriately obtained from the plant monitoring means 2 and placed at corresponding display positions.

In this case, the system monitoring screens Aa, Abc, Ad, As are split screens O81, DS2. DS3. Located in DS4. In addition, since there is a next screen at this time, the touched coordinates of the touch screen device 9 notified by the input processing means 11 in that state are included in the area NP, and when it is notified that the area NP has been touched, the same As shown in Figure (b), the display screen is switched to the next page of the system monitoring screen. In this case, the system monitoring drawing Af.

8g+Ag are split screen DSI, DS2. DS3
, and a blank display is displayed on the split screen DS4.

Further, in this state, when it is notified that the region MP of the touch coordinates of the touch screen device 9 has been touched, the display control means 6 returns the display contents of the CRT 7 to the state shown in FIG.

Now, when the operator touches the system monitoring screen Aa displayed on the split screen DSI while the system monitoring screen shown in FIG. 11, the display control means 6 is notified.

Thereby, the 1 display control means 6 controls the touch area TSI.
Search for the alarm point table l1lPT of the system monitoring screen Aa displayed on the split screen DSI corresponding to .

Then, by referring to the monitoring pattern registration pointer PP of the alarm point table VPT, of the contents registered in the area GPa of the monitoring pattern display registration means 5, the trend graph monitoring screen, logic monitoring screen and group trend monitoring screen are selected. The first one for each, namely trend graph monitoring screen Bjao, logic monitoring screen Bkao and group trend monitoring screen BQao.
