Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a process instrumentation monitoring system, and particularly to a method for displaying a process flow diagram on a screen.

(Prior Art) A conventional method for displaying a process flow diagram on a screen will be described with reference to the operation panel shown in FIG. The process flow diagram to be displayed as an image should be based on the overall plant diagram.
The fourth level is a second level developed from this overall diagram, a third level developed for each flowchart at the second level, and a loop diagram showing the minimum unit developed for each flowchart at the third level.

On the screen display operation panel (1), there are dedicated call buttons for each level to specify the level, that is, the No.
PL), third level (GP), fourth level (PT), and image display mode designation push buttons (PF) and (TAG) are arranged in the center. The push button (PF) is used to specify the image display mode to the process flow diagram, and the push button (TAG) is used to call up a screen displaying a list of signal names corresponding to each flow diagram at the second level. be.

On the right side of the dedicated call button, a group of call buttons (2) dedicated to displaying flowcharts are arranged, which correspond one-to-one to frequently used flowcharts among the flowcharts at the second level. The number of button groups (2) is naturally limited by the space on the operation panel (1).

To the left of the dedicated call push buttons (PL) to (PT) for each level, there is a shift push button (FW) that is commonly used for each level.
.

(BW) is placed. When the shift push button (FW) is operated, the flow diagram before the currently displayed flow diagram is displayed, and when the shift push button (BW) is operated, the flow diagram after the currently displayed flow diagram is displayed.

The screen display method using the operation panel (1) having the above configuration is as follows.

When the dedicated call push button (PL) is operated, an overall plant diagram is displayed on the screen of an image display (not shown). Next, when you want to see the second level flow diagram, operate the 1-image display mode designation button (PF) to designate the image display mode to flow diagram display mode, and select one of the flow diagram display call buttons (2). When the call push button corresponding to the desired second level flowchart is found and operated, the flowchart is displayed on the screen. To view yet another second-level flowchart, find and operate the call button corresponding to that flowchart. Second-level flowcharts other than those registered in the flowchart display call button group (2) cannot be displayed with one touch, so after displaying a similar flowchart, press the shift button to find it. There must be.

If you want to view the second level signal name list display screen, operate the image display mode designation button (TAG) to designate the tag type display mode, and press the dedicated call button group (2
), just press the desired button.

As for the third level flowchart, by operating the dedicated call push button (GP), the flowchart with the lowest number registered in the memory is displayed.

Therefore, in order to display the necessary flow diagram, the shift push button (B11) must be operated several times.

For fourth-level flow diagrams, a dedicated call pushbutton (P
After operating T), the shift push button (BV) must be operated several times in the same manner as above to obtain the desired flow diagram.

(Problems with the Prior Art) As is clear from the above, the conventional process flow diagram screen display method has the following problems.

l) Group of call buttons dedicated to displaying second-level flow diagrams (2)
Since the number is limited due to panel space, many of the second level flow diagrams cannot be displayed with one touch.

2) Group of call buttons dedicated to displaying the second level flow diagram (2)
It is not easy to find the desired push button.

3) In the dedicated call button group (2), the positions of the mutually related push buttons in the flow diagram are difficult to understand.

4) In the case of the third level and the fourth level, it is necessary to repeat the button operation several times to display the desired flow diagram, which is complicated.

5) When an alarm occurs, it is difficult to intuitively understand the location of the instrument where the alarm is occurring because there is no means for quickly displaying a flow diagram that includes the location where the alarm occurs.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for displaying a process flow diagram on a screen that can solve the above-mentioned problems.
