Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an information display method in a display,
Specifically, in various plants, etc., when monitoring equipment connected to a process for abnormalities and operating it using a CRT, input alarm signals from the equipment to the monitoring computer (
The present invention relates to an information display method for displaying information such as alarm contents and subsequent countermeasures on a CRT screen based on a so-called annunciator signal.

(Prior Art) Conventionally, as this type of display system, there is one shown in FIG. 3, for example. In the same figure (a), Di is a plurality of alarm signals such as digital signals inputted to a monitoring computer via a data input device such as a process input device,
These alarm signals Di are detected by the state change detection program 51 when the state changes (for example, the logic of the signal is changed from "0" to "1").
”), the occurrence of an abnormal state of the device is recognized, and after a predetermined logical operation with other alarm signals Di, a display signal S indicating information such as the content of the alarm and subsequent countermeasures is generated.
d is output.

Based on this display signal Sd, predetermined display positions 53a to 5 on the CR7 screen 52 are selected as shown in FIG.
In order to display information on Sd1.3d, each display signal Sd1.3d is displayed as shown in FIG. Sd,..., and specific display information such as characters corresponding to each of these IXIr
z+... and any display position [53a, 53
Display table 5 associated with b,...
4 is created and stored in a memory or the like.

Thus, the monitoring computer determines a display signal when a predetermined alarm signal Di is input, and displays it in the display table 54.
, and selects the display information corresponding to the display signal, and displays the display information at a designated display position on the CR7 screen 52 via a display controller or the like.

(Problems to be Solved by the Invention) However, in the conventional display system described above, the alarm signal Di is usually input in correspondence with the physical terminal number of the data input device, and the state change detection program 51 is Special problem language (POL: Progr)
Since the information is created in an internationally oriented language, there is a problem in that it requires a great deal of effort for non-experts in sequence control and programming languages to display the information on the display.

Furthermore, when changing the specifications of display signals, display information, etc., the operator himself or herself may rearrange the state change detection program 51 while taking into account the terminal numbers of the data input device.
It is necessary to rearrange the display table 54, which has the drawback of being extremely complicated.

The present invention was proposed to solve the above-mentioned problems, and its purpose is to enable even non-experts in sequence control, programming languages, etc. to associate alarm signals with terminal numbers. An object of the present invention is to provide an information display method on a display which allows information to be displayed easily without being bothered by the above, and which can also flexibly respond to changes in display specifications.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides input such as an alarm signal indicating an abnormality of various devices installed in a process on a display definition screen provided on a display screen. The type of signal (tag number) and the logical product of these input signals,
The logic such as logical sum, the type of display signal (tag number) such as an alarm that should be displayed on the display screen when this logic is established, and the specific display information such as characters corresponding to this display signal. the type of the input signal, the type of logic 9 display signal 9 display information, and the display position of this display information on the display screen are stored in advance as a table, and the display information is read from the table according to the type of the input signal. is displayed at a predetermined display position.

(Function) In the present invention, the operator sets the type of input signal using, for example, a tag number as a practical signal name in the setting section provided on the display definition screen.

Furthermore, by setting logic, display signals, display information, etc. based on these input signals, a state change detection table and a display table in which these items are made to correspond to each other are created.

With this, when an input signal from a device etc. is input to the monitoring computer, display information corresponding to the input signal is read out from the table and automatically displayed at a predetermined display position on the display. (Example) Hereinafter, an example of the present invention will be described along with the drawings.

First, in FIG. 1, 1 is a display definition screen.

This display definition screen 1 includes a setting section 2 for setting the type of input signal Di such as an alarm signal from various devices, a setting section 3 for logic using the input signal Di, and a setting section 3 for setting the type of input signal Di such as an alarm signal from various devices, and a setting section 3 for setting the logic using the input signal Di. A display signal setting section 4 and a setting section 5 for setting specific display information such as characters meant by the display signal are provided. Each of these setting sections 2 to 5 is a blank section, and the operator can input each of the above items using an input device such as a keyboard. Here, the type of input signal Di is not the physical terminal number of the data input device, but a tag number similar to a practical name [for example, rAN+
ui, (Annunciator) Di", etc.), and now, let's assume these tag numbers are DttD,...
The same applies to display signals, and for example, a tag number of A4 is used.

In defining the display, the operator first sets the input signal Di in the setting section 2 using a tag number. Assume now that the input signals Di to be set are D1 to D4. Next, the logic based on the input signals D1 to D4 is set in the setting section 3. This logic is, for example, a logical product or a logical sum, and a simple example is a logic for displaying an alarm when a plurality of input signals become "1".

Next, specific display information in characters such as a warning to be displayed when the above logic is established, such as ``engine'', is set in the setting section 5. Then, the tag number of the display signal associated with this display information is set in the setting section 4.

Next, a display table 7 is created from these items by the display definition program 6. This display table 7 includes the tag number of the display signal, the display position [9a to 9d] on the display screen 8, the display information corresponding to the tag number, and the position # corresponding to the display position. A (X, Y), etc., and among these, the tag number of the display signal and the corresponding display information are input on the display definition screen 1 and set by the compile function described later. The operator only has to select and set any one of the display positions 98 to 9d, and the position coordinates (X, Y) are uniquely determined once the display position is determined. In the example shown in Figure 1, display positions 9a and 9b are set for two display signals (tag numbers A, A2), respectively, and the display information is ■□y rz
, the position coordinates are (Xl, Y,), (X,.

yz).

Here, the display table 7 and the state change detection table 10 shown in FIG. 1 are specifically created by the compile function shown in FIG. 2. The state change detection table 10 associates the logic of the input signals D□ to D4 whose states have changed due to the occurrence of an abnormality in one device with the tag number of the display signal corresponding to this logic.

That is, in FIG. 2, in step S1, the tag number of the display signal input on the display definition screen 1 is set in the state change detection table 10 and the display table 7. Next, in step S2, since the following processing differs depending on the type of input signal, the type is determined based on the tag number. Next, in step S3, the terminal numbers of the installed data input devices are assigned to the tag numbers of the input signal Di in a one-to-one correspondence. Then, in step S4, the tag number is converted into a logical address corresponding to the terminal of the data input device.

Further, in step S5, a state change detection table 10 is created based on the logical address and the logic set on the display definition screen, and in step S6, a state change detection table 10 is created based on the logical address and the logic set on the display definition screen. A single display table 7 is created by setting display information. And these state change detection table 10
and display table 7 are stored in memory.

When the input signal Di is taken into the monitoring computer, the state change detection program 11 in FIG.
refers to the state change detection table 10 and outputs the tag number of the display signal, for example A1, according to predetermined logic.

As a result, the state change detection related to the tag number A1 is turned ON, and the display position 9a on the display screen 8 corresponding to the tag number A is referred to the 1 display table 7.
Display a predetermined display information □. In this way,
Display information such as an alarm corresponding to the input signal Di such as an alarm signal can be displayed on the CRT screen.

Note that the number and type of input signals Di, the type of logic set, etc. are not limited to the above embodiments.
It is possible to change it arbitrarily.

(Effects of the Invention) As detailed above, according to the present invention, desired information can be displayed for an input signal simply by the operator inputting predetermined items into each setting section of the display definition screen. Even a person other than a sequence control expert can easily display alarms, etc. without having to worry about associating terminal numbers with others.

In addition, since the state change detection program can be used as a package, there is no need for operators to be proficient in languages such as POL. This has the advantage that there is no need to rearrange or rearrange the display table or the like.
