When the operator touches a desired instrument part on the graphic display screen of the display device 1, the touch panel 3 detects the touched position and inputs it to the instrument pattern display control section 5 to display the instrument pattern. The control unit 5 reads out the instrument pattern for the instrument component from the data file 6 and displays it in an interrupted manner on the graphic display screen of the process flow of the display device 1 (step S2). The number of interrupt displays of this instrument pattern can be arbitrarily performed up to the number of sheets which is the operator's intention. However, in the following, instrument tag numbers FC101, FC102,
Assume that instrument patterns are displayed for the three TCs 101.

Next, the instrument group registration process starts. At the stage of screen display shown in step S2, the instrument group registration unit 7 writes the interrupt tag table 21 in the data file 6.
And the operator touches the instrument group registration key 22 on the screen of the display device 1 (step S3) to register the interrupt tag table 21 as a group display screen tag table 23 in the data file 6 ( Step S4).

If it is desired by the operator to simultaneously display the real-time trend graphs for these measuring instruments as a group at the stage of the display screen in step S2, the real-time trend registration key 24 is displayed on the screen of the display device 1. By touching (step S5), the interrupt tag table 21 described above is used as the real-time trend screen tag table 25 and the data file 6
(Step S6).

Next, if it is desired to collectively display the instrument patterns of a plurality of instruments registered as a group, the instrument group display control unit 8 causes the display device 1 to display a group list as shown in FIG. 3 (step S11). (The actual operation is to select the group display key from the menu of the display device 1.).

In this embodiment, the group list also displays the selection keys of the instrument pattern display (GP) key 26 and the real-time trend display (RT) key 27.

Therefore, if the instrument pattern of the group registered by the operator is registered in the group 1 (GP1), by touching the key of the group 1 and the instrument pattern display key (GP) 26, Instruments FC101, FC102 registered in Group 1,
The instrument pattern for the TC 101 is automatically displayed (step S12).

Similarly, if it is desired to collectively display the real-time trend graphs of a plurality of instruments registered in a group, the instrument group display control unit 8 displays a group list as shown in FIG. 4 on the display device 1. Then, by touching the key of this group 1 and the real-time trend display key (RT) 27 (step S21), the instrument FC10 registered in this group 1 is touched.
Real-time trend graphs for 1, FC 102, and TC 101 are automatically displayed (step S22).

In this way, as shown in FIG. 2, the operator sequentially touches a plurality of instruments that he / she wants to group in a state in which a process flow is displayed on the display device 1 and interrupts those instrument patterns sequentially. To display
After that, if you want to register those instrument patterns in a group, touch the group registration key 22 of the instrument pattern, and if you want to register the real-time trend graph of those instruments in a group, touch the real-time trend graph registration key 24. Arbitrary instruments can be freely group-registered, and after registration, as shown in FIGS. 3 and 4, the instrument patterns of those instruments can be collectively displayed, or the real-time trend graph can be collectively displayed. .

It should be noted that each of the display screen tag tables 23 and 25 registered in the data file 6 shown in FIG. 2 includes those which are group-registered by the conventional method. The interrupt tag table 21 created in this embodiment is additionally registered to each of the display screen tag tables 23 and 25 registered by the conventional method.

Next, another embodiment of the invention of claim 1 is shown in FIG.

Compared with the configuration of the first embodiment shown in FIG. 1, the real-time trend in the group is shown. A feature is that the collective display control unit 10 is omitted. Therefore, the processing of the instrument group registration unit 7 also omits the function of registering the tag table of the real-time trend group (functions of steps S5 and S6 shown in FIG. 2), and the configuration is simplified.

However, in FIG. 2, step S1
By the processing of S4, the operator can freely register a group of instruments by displaying the instrument pattern of the instruments desired to be grouped by interruption and performing a group registration operation. By the process shown in (1), the instrument patterns of those instruments can be displayed together.

Next, another embodiment of the invention of claim 2 is shown in FIG.
It will be described based on. In the third embodiment, a plurality of instruments are group-registered to enable the real-time trend graphs to be collectively displayed. The first embodiment shown in FIG.
The configuration is characterized by omitting the in-group instrument pattern collective display control unit 9 as compared with the configuration of the embodiment. Therefore, the processing of the instrument group registration unit 7 is also performed by the instrument table group tag table registration function (step S shown in FIG. 2).
(Functions 3 and S4) are omitted, and the configuration is simplified.

However, in FIG. 2, step S
By the process of 1, S2, S5, S6, the operator can interrupt the instrument pattern for the instruments that he / she wants to group into, and perform the group registration operation to freely register any instrument, and after registration, By the processing shown in FIG. 4, the real-time trend graphs of those instruments can be collectively displayed.

Next, an embodiment of the invention of claim 4 will be described with reference to FIGS. The plant monitoring and controlling apparatus according to the fourth embodiment compares the measurement data of each instrument with the tag number of the instrument to make the variable data table 31.

The processing that is read out and performed by each control unit is actually realized by the CPU executing the corresponding control program registered in the data file 6, but for convenience of explanation, a different group of control programs is provided. The control processing according to is shown as each control unit.

Next, the operation of the process monitoring control apparatus of the fourth embodiment having the above configuration will be described.

<< Generation of Variable Data Table >> FIG.
In the variable data table 31 in the data file 6 shown in each of FIGS. 9A and 9B, the measurement data 31a of various instruments is periodically updated and registered in association with the tag (TAG) number 31b. The automatic registration of the group identification data consisting of the search key data 31c and the subordinate group data 31d in the variable data table 31 is executed by the following procedure.

First, the process flow display control unit 2 accesses the data file 6 to read the graphic data of any process flow of the monitored plant and display the process flow on the display device 1 graphically. Further, the process flow display control unit 2 accesses the variable data table 31 to read out the tag numbers 31b and measurement data 31a of the instruments included in the process flow to be displayed and display them at the corresponding positions (step S41).

Then, when the operator touches a desired instrument part on the graphic display screen of the display device 1, the touch panel 3 detects the touched position and inputs it to the instrument pattern display control unit 5 to display the instrument pattern. The control unit 5 reads out the instrument pattern for the instrument component from the data file 6 and displays it as an interrupt on the graphic display screen of the process flow of the display device 1 (step S42). The number of interrupt display of this instrument pattern can be arbitrarily performed up to the number of sheets which is the operator's intention. However, in the following, instrument tag numbers FC101, FC10
It is assumed that instrument patterns are displayed for three of TC2 and TC201.

Next, the registration process of the group identification data of the variable data table 31 is started, and the operator touches the instrument group registration key 32 on the screen of the display device 1 (step S43). Register one in the search key data 31c and the subordinate group data 31d of the group identification data part of the variable data table 31 by using one tag number of the instrument that is not specified as a search key, and the other instruments as subordinate to that group. Yes (step S44). In the variable data table 31 shown in FIGS. 8 and 9, the search key is GP1,
Although they are illustrated as GP2, GP3, ..., They correspond to instrument tag numbers FC101, TC201, TC301 ,. Also, for example, the tag number TC
In the column of 201, the key data 31c is 2 is
It shows that this instrument TC201 is registered as a representative instrument of one group, and the dependent group data 3
1 and 3 are registered in 1d because the instrument TC201 is a group 1 represented by another instrument (this is instrument FC101
Representative group), group 3 (this is instrument TC
(A group represented by 301) is subordinate to each group. In addition, the instrument tag number FC102 is not registered in the search key data 31c is this instrument FC1.
02 indicates that a representative group is not registered, and 1 and 2 are registered in the subordinate group data 31d. In the group 1 typified by the instrument FC101 and the group 2 typified by the instrument TC201, respectively. It indicates that it is registered.

Next, if it is desired to collectively display the instrument patterns of a plurality of instruments registered as a group, the operation according to the flowchart of FIG. 9 and the flowchart of FIG. 10 is performed. First, the process flow display control unit 2 causes the display device 1 to perform a graphic display of the process flow. The graphic display of the process flow by the process flow display control unit 2 is the same as step S41 shown in FIG. 8, and the fixed screen 33 of the process flow and the measurement data of the corresponding instruments of the variable data table 31 are combined and displayed ( (Step S51 in FIG. 9, step S61 in FIG. 10).

Then, on the composite screen 34, a group display soft key or keyboard 4 prepared in advance is used.
When one of the instruments, FC101 in this case, is touched together with the group display hard key 35 pre-assigned to (in step S52 in FIG. 9, step S62 in FIG. 10), the in-group instrument pattern collective display control unit 13 Referring to the variable data table 31, this tag number FC101 is registered as one representative instrument, and FC102 and TC201 registered as a subordinate group of this group (that is, subordinate group data in the variable data table 31). An instrument in which the group 1 (corresponding to the group represented by the tag number FC101) is registered in 31d is extracted (see FIG. 10).
Steps S63 to S65) in these instruments FC
The instrument patterns of 101, FC102, and TC201 are collectively displayed on the display device 1 as one group (step S53 in FIG. 9, step S66 in FIG. 10).

In step S52 in FIG. 9 and step S62 in FIG. 10, the group display key 35 is displayed.
If is not operated, only the instrument pattern corresponding to the touched instrument is displayed as an interrupt (step S67 in FIG. 10).

Even if the group display key 35 is operated in step S52 in FIG. 9, even if the instrument tag number touched with it is a representative group number such as FC102, which is not registered in the group, Only the instrument pattern of the FC 102 will be displayed as the search result of the variable data table 31 (step 54 in FIG. 9).

In this way, in the plant monitoring and controlling apparatus of the fourth embodiment, arbitrary plural instrument patterns are displayed as interruptions on the process flow display screen, and their groups are registered to the variable data table. By registering a group, and then operating the instruments and group display keys on the process flow display screen, it becomes possible to display all instrument patterns of the registered group at once, which is required at the time of design. It is possible to reduce the labor required for technicians to register the group, and the labor required for the operator to register the group on the actual machine. Group registration is possible and operability is improved.
