Abstract

PURPOSE:To know the state of an equipment at a glance and to execute an instruction and countermeasure to the abnormality, etc., with the operation of irreducible minimum. CONSTITUTION:The screen 2 of a display 1 is divided into plural pieces to form plural segments 3. The content of the segments 3 is changed over by a signal from a program controller. When one load becomes abnormal, the abnormality content ('pressure reduction', e.g.) is displayed on one segment 3 by a signal from the program controller. Then, a touch switch formed at the front face of the segment 3 is operated to select a corresponding segment 3. In the case, a screen under the hierarchy of the segment 3 is called and the content of the instruction/countermeasure to abnormality ('is a bulb shut?', e.g.) is displayed. An operator properly deals with abnormality by looking at the display.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen system of a display used in a program sequencer.

[0002]

2. Description of the Related Art A program sequencer of this type is composed of a program controller, which is a control device for controlling a plurality of loads, and a display device for displaying contents such as load abnormalities and instruction measures. Conventionally, regarding the screen called on the display unit by the signal from the program controller, the screen that can be called by operating the switch equipped on the display unit to know the detailed contents such as abnormalities and instruction measures, etc. there were.

That is, as shown in FIG. 4, the contents (for example, "abnormality occurrence, pressure decrease") called by a signal from a program controller or the like are displayed on the screen of the display. Looking at the display on this screen, switch the screen by operating the switches such as cursor keys equipped on the display,
The contents of the instruction measure for the abnormality (for example, "Is the valve closed?" Are displayed. The operator takes appropriate action by seeing this display.

[0004]

However, in such a conventional example, it is only for one abnormality, and for a plurality of abnormalities, the details cannot be known at the same time for each abnormality. There was a problem. The present invention has been provided in view of the above-mentioned points, and it is possible to understand the states of a plurality of devices at a glance, and to display a screen of an indicator for the purpose of taking instruction measures against abnormalities and the like with a minimum necessary operation. It provides a method.

[0005]

SUMMARY OF THE INVENTION The present invention is a system including a control device for controlling a plurality of loads and a display device for displaying contents such as load abnormality and instruction countermeasures. The display device is divided into two parts, and the contents of instruction measures for abnormalities and the like are switched and displayed on the screen by operating a switch provided on the display.

[0006]

Thus, the states of a plurality of devices can be seen at a glance, and instruction measures for abnormalities can be performed with the minimum necessary operations.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, the screen 2 of the display 1 is divided into a plurality of segments to form a plurality of segments 3. Here, the contents of segment 3 are switched by a signal from the program controller. Here, when a certain load becomes abnormal, the content of the abnormality (for example, “pressure decrease”) is displayed in a certain segment 3 as shown in FIG. 1A by a signal from the program controller. When a touch switch is formed on the front surface of the segment 3, the touch switch is operated, and when there is no touch switch, the cursor 4 is moved by the cursor key,
Use function key 5 to select the corresponding segment 3.

In this case, as shown in FIG. 1 (b), the screen under the layer of segment 3 is called up, and the contents of the instruction measure for the above-mentioned abnormality (for example, "is the valve closed?") Are displayed. To be done. The operator looks at this display and takes appropriate action. In addition, from the screen of FIG.
When switching to the screen of (a), the ESC key or the like provided on the display 1 is operated to switch.

FIG. 3 shows a block diagram of the display device 3. In FIG. 3, an input / output interface unit 11 that exchanges data with the program sequencer 1, a control unit 12 that includes a CPU that controls the whole, and a display unit 14 that includes a CRT or the like that displays a command or load state, Display 1
4, a system controller 13 for generating clock pulses, a memory 17 for storing data, a switch 16 for receiving input data, and the like.

In FIG. 3, display contents corresponding to signals from the program controller of segment 3 on the screen,
The screen below the layer of segment 3 is created at the time of creating the screen, and is stored in the memory unit 17. The control unit 12 reads data from the memory unit 17 based on the data from the input / output interface unit 11, and the display controller 1
5 is displayed on the display unit 14. Also, the switch unit 1
Based on the input information from 6, the data is read from the memory unit 17 and the screen below the hierarchy is displayed or the segment 3
To return to the screen.

As described above, by operating the switch provided in the display 1, it is possible to call the screen below the hierarchy of one of the plurality of segments 3 in the display 1, regardless of the program controller. Therefore, it is possible to know the details of one thing that one wants to know from a plurality of pieces of information.

[0012]

As described above, the present invention is a system including a control device for controlling a plurality of loads and a display device for displaying contents such as load abnormality and instruction measures, and the like. It is divided into two parts, and the contents of instruction measures etc. for abnormalities etc. are switched and displayed on the screen by operating the switches provided on the display, so the status of multiple devices can be seen at a glance and those abnormalities etc. With this, it is possible to take an instruction countermeasure against the above with a minimum required operation.
