Abstract

PURPOSE:To facilitate a program adjustment by displaying a program monitor picture, a program tuning picture and a data trend graph picture on a same display screen dividedly simultaneously or timewise sequentially and displaying a variable and a constant on the picture. CONSTITUTION:The program monitor picture A1, the program tuning picture B1 and the data trend graph picture C1 are displayed on the display screen while being divided into three parts. Further, the variable on the program monitor picture and the constant on the program tuning picture are displayed and the program monitor picture, the program tuning picture and the data trend picture are displayed while the same display screen is divided simultaneously or timewise. When the erasure request of the program tuning and data trend graph exist, each pattern is erased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program display method for displaying the contents of programs and data for digital control on a monitor.

[Conventional technology]

FIG. 3 is a block connection diagram of a conventional program display device. In the figure, 1 is an input device such as a keyboard that requests display of images of program monitor, program tuning, and data trend graph, and 2 is this input device 1.
The programming device f13 reads out programs and program tuning data trend graphs from the memory of the digital control device 4, edits them, and outputs them in accordance with display requests made by the programming device 2. This is a display device such as a CRT display that displays each monitor image.

Next, the operation will be explained.

First, when the programming device 2 is requested to display all program monitor images, the program monitor image A is displayed on the display screen 3A of the CRT display 3, as shown in FIG.
K is displayed. Variable values are displayed on the block diagram of the control program 2 displayed as program monitor image A, and these variable values are periodically fetched from the digital control device 4 by the programming device 2 and the display is updated. . Further, when a request is made to display a program tuning image, the image shown in FIG. 5 is displayed, and on this program tuning image B, constant values of a certain block of the control program are displayed. Note that this constant value is used for tuning (
change) possible. Furthermore, when a request is made to display a data trend graph, image C in Figure 6 is displayed, and on this data trend graph image C, a certain variable value is displayed as a line graph from a certain time in the past to the present on the display screen 3A. be done.

[Problem that the invention seeks to solve]

Since the conventional program display method is as described above, the program monitor image, program tuning image, and data trend graph image can be displayed on the display screen 3 according to requests.
A must be displayed selectively at different times, and three images cannot be displayed at the same time, and the content of each image cannot be monitored simultaneously, making program adjustment cumbersome. There were problems such as:

This invention was made to solve the above-mentioned problems, and it is possible to display a program monitor and a program monitor on the same screen of the output device.
The purpose of the present invention is to obtain a program display method that can display each image of program tuning and data trend graphs separately and simultaneously, and monitor the contents of these programs and data at the same time.

[Means for solving problems]

A program display method Fi according to the present invention, a program monitor image, and a program tuning image.

The data trend graph image is divided on the same display screen and displayed simultaneously or one after the other, and variable values on the program monitor image and constant values on the program tuning image can also be displayed. .

[For production]

The programming device according to the present invention displays a program or data read from a digital control device according to a display request, and displays a program monitor image.

It functions to divide the same display screen and display them simultaneously or sequentially as a program tuning image and a data trend graph image, and it also functions to display variable values and constant values of each monitor image.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 11 is a display screen of the CRT display 3, and this display screen 11 includes a program monitor image Al.
, program tuning image B1, and data trend graph image C1 are displayed divided into three parts. and,
The display of each of these images AI, Bl, and CI is performed by the following processing by the programming device 2 shown in FIG. FIG. 2 is a flow diagram showing the procedure of such processing.

First, when a request to display a program monitor image is made using the input device 1, the programming device displays the program monitor image Alt on the entire display screen 11 in a state similar to that shown in FIG.
After that, the variable values on the program monitor image A1 are periodically updated (step 28).
. Here, it is checked whether there is a request to display each image of the program tuning and data trend graph (Stella/3S), and these images Bl and Ci are displayed separately on the same display screen 11 together with the above image A1 (step 48). Here, it is checked whether the program tuning image B1 is being displayed (step 5S), and if it is being displayed, the program constants are tuned in the program tuning image B1 (step 68). Also,
If the program tuning image B1 is not displayed and the process of step 6S is completed, it is checked whether the data trend graph image C1 is being displayed (step 7S), and if it is being displayed, The data trend graph screen is updated (step 8S). After this, it is checked whether there is a request to erase each screen of the program tuning and data trend graph (step 9S), and if there is a request to erase each screen, the screen is erased (step 10S), and as shown in FIG. The image A shown will be displayed on the entire display screen 3A. Thereafter, the program monitor image is updated and the processing from step 28 onwards is repeated.

Note that in the above embodiment, the program tuning image B
1 and the data trend graph image C1 are requested, the screen 3A is divided into three parts. From the time the display of the program monitor image A1 is requested, the screen 3A is divided into three parts, and the program tuning image Blt is divided into three parts. The other two may be left vacant until display of the data trend graph image C1 is requested.

〔Effect of the invention〕

As described above, according to the present invention, since the program monitor, program tuning, and data trend graph images are displayed simultaneously on the same screen of five display devices, it is possible to monitor the comparison of each image. This has the effect of making it easier and faster to adjust the control program.
