Next, the registration section 6 displays the system abnormality setting screen 20 and the process abnormality setting screen 21 corresponding to the group number "2" as shown in FIG.
Display on RT12 ₂ . The system abnormality setting screen 20 is a screen for setting the validity or invalidity of the abnormality signal for each station.
Is a screen for setting valid or invalid of an abnormal signal for each signal section.

For example, in the system abnormality setting screen 20,
ON icon 23 ₁ that indicates validity for each station number 23 ₁ ~
23 _n and an OFF icon 24 _{1 to} 24 _n indicating invalidity
Is displayed, and an execution icon 25 for sending the selection state of each station by these icons 23, 24 to the registration unit and a cancel icon 26 for canceling this selection state are displayed. Similarly, on the process abnormality setting screen 21, ON icons 27 _{1 to} 27 _n indicating validity and OFF icons 28 _{1 to} 28 _n indicating invalidity are displayed for each signal division number, and each station by these icons 27 and 28 is displayed. Registration state of the selected state of 6
An execution icon 29 for sending the selected item and a cancel icon 30 for canceling the selected state are displayed.

On the system abnormality setting screen 20 and the process abnormality selection screen 21, the operator touches the ON icons 23 ₂ and 28 _{3 of the} station number "2" and the signal division number "3", for example, and It is assumed that the execution icons 25 and 29 are touched after the OFF icons of the station number and the signal division number are touched. The input control unit 3 detects this touch operation by the touch panel 1 and sends a registration command to the registration unit 6 in accordance with the detection result. According to this registration command, the registration unit 6 receives the station number "2" of the data area corresponding to the group number "2" in the monitoring group table 4.
In addition, the signal division number "3" is made valid, and other station numbers and signal division numbers in the data area are set invalid. Thus, in the CRT 12 _2, it is set to monitor the abnormal signal corresponding to the station number error signal and the signal segment number corresponding to the "2""3" as the monitoring group "2".

Thereafter, the CRT 1 is operated by the same touch operation.
In 2 _1, it is set that the abnormal signal corresponding to the station number “3” and the abnormal signal corresponding to the signal division number “2” are monitored as the monitoring group “1”.

Here, it is assumed that a process abnormality has occurred in the execution control PCS 13 ₂ . PCS for execution control
13 ₂ sends a process abnormality signal corresponding to the signal division number “3” to the determination unit 7 in the monitoring device body 11. Based on this process abnormality signal, the determination unit 7 detects the occurrence of abnormality (ST1), determines whether it is a process abnormality (ST2), and when the determination result is negative, further determines whether it is a system abnormality. (ST3), in this case step ST
Since the determination result of 2 indicates that the content of the abnormality is the process abnormality, the in-group process abnormality index initial value is calculated according to the following equation (1).

[0024]

[Equation 1]

That is, the determination unit 7 obtains the process abnormality index initial value = 4 + (3-1) = 6 and sets the process abnormality index initial value "6" in the internal memory (not shown) (ST4).

Next, the judging section 7 judges whether or not the CRT number exceeds the maximum value (ST5). When the judgment result shows that the CRT number does not exceed the maximum value, the CRT 12 is referred to by referring to the group allocation table 5. ₂ group number determined to be valid in response to (= 2) with reading (ST6), based on the read group number to calculate the absolute index as shown in the following equation (2).

[0027]

[Equation 2]

That is, the determination unit 7 obtains absolute index = 7 × (2-1) + 6 = 13. Subsequently, the determination unit 7 reads a setting indicating valid or invalid for the signal division number (= 3) indicated by the area number corresponding to the absolute index (= 13) (ST7). Further, the determination unit 7 determines whether or not the setting read in step ST7 is valid (ST8), and when the determination result indicates that the setting is valid, executes the abnormality occurrence process and returns to step ST5 (ST9). ), When the result of determination in step ST8 indicates that the setting is invalid, nothing is done and the process returns to step ST5. As the abnormality occurrence processing, for example, screen display by a CRT, abnormality notification by a sound output from a buzzer (not shown) and a speaker (not shown) can be used.

Further, the apparatus of this embodiment returns from step ST8 or step ST9 to step ST5, and then performs CR
For T12 ₁ executes the same manner as described above the processing in step ST6 to step ST9.

As a result, in the apparatus of this embodiment, C
RT12 ₂ monitors only abnormal signals related to station number "2" and signal division number "3", and CRT12 ₁ monitors only abnormal signals related to station number "3" and signal division number "2". Can be executed.

Next, the operation when a system abnormality occurs in the execution control PCS 13 ₂ will be described. As described above, the execution control PCS 13 ₂ sends the system error signal corresponding to the station number “2” to the monitoring device main body 11
Is sent to the determination unit 7. The determination unit 7 executes steps ST1 and ST2 in the same manner as described above, and executes step ST2.
It is determined whether or not the abnormality is a system abnormality because the result of the determination indicates that the abnormality is not a process abnormality (ST3). As a result of this determination, the content of the abnormality indicates a system abnormality. The index for use is calculated according to the following equation (3).

[0032]

(Equation 3)

That is, the determination unit 7 obtains the system abnormality index initial value = 0 + (2-1) = 1, and sets the system abnormality index initial value "0" in an internal memory (not shown) (ST10).

Thereafter, the processes of steps ST4 to ST8 are executed as described above. However, in the case of system abnormality, the absolute index is calculated according to the following equation (4) instead of equation (2).

[0035]

[Equation 4]

That is, the judging section 7 calculates absolute index = 7 × (2-1) + 1 = 8, and executes the same processing as described above based on this absolute index. As described above, in the apparatus of this embodiment, the process abnormality and the system abnormality can be individually monitored.

Next, in the apparatus of this embodiment, as a case where it is desired to invalidate a desired abnormal signal, the execution control PCS 13
