Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic computer program creation device.

As general-purpose programmable controllers have been developed and their applications have expanded, programming has become easier and easier to handle without requiring specialized knowledge in order to simplify programming work, save labor, and facilitate maintenance of the controllers. The demand for coolness is increasing, and to meet this demand, automatic computer program creation devices have been developed.

The present invention is based on such an automatic creation device and relates to improvements in its operability.

FIG. 1 is a system configuration diagram showing a computer program automatic creation device (hereinafter also simply referred to as creation device) and related equipment on which the present invention is based. In the same figure, 1#'i creation device, 2 a programmable controller, 3 a printer, 4 an EPROM, 5 a cassette tape, 6 a program 1 and 7 printed in a ladder diagram format, and programs 1 and 7 printed in a binary format. program,
8 is a ladder diagram created for input.

The program is created by creating a ladder diagram 8 according to the control details, and then drawing the same ladder diagram on the CRT screen by directly operating keys corresponding to each circuit element in the creation device 1. be done. The ladder diagram is converted into machine language for the programmable controller 2 and sequentially stored in the internal program memory of the creation device 1. The stored programs can be transferred to the controller 22 or external equipment (EPRO) as necessary.
M4° cassette tape 5, etc.). If a printer 3 is connected to the creation device 1, it is also possible to print the program as a ladder diagram 6 or a binary format glue store.

FIG. 2 is a block diagram showing the internal configuration of the creation device l. In the figure, 11 is a CPU, 12 is a memory, 13 is a CRT interface, 14 is a cassette interface, 15 is a keyboard interface, and 16 is an EF
ROM interface, 17 is a printer interface, 18 is a programmable controller interface, 19 is a CRT, 20 is a keyboard, and B is a bus.

Now, the problems with the operability of the computer program creation apparatus as explained above will be explained below.

Normally, when monitoring a created program in an automatic computer program creation device, it is not possible to monitor an area that exceeds the area of the CRT screen because there is a physical limit to the size of the CRT screen. Therefore, in order to monitor programs that are located at separate addresses, there is a drawback that they must be monitored separately.

For example, output I O0,1 becomes 100 steps, output I O0,1 becomes 100 steps,
When output 100.2 is at 200 steps and you want to monitor them, output 100.1 and output 100.2 cannot be displayed on the CRT screen at the same time, so output 100. 1 on the CRT screen and then read out the output 100.2 as shown in FIG. 4, the output i o o, i disappears from the CRT screen.

Therefore, there is a drawback that output 100.1 and output 100.2 cannot be monitored simultaneously.

Furthermore, if a plurality of specified circuits are edited and monitored on the same screen in order to avoid this, there is a drawback that the screen configuration will be far different from the actual program.

In general, in sequence programs, it is very common to use conditions set at one location to determine conditions at another location. is often not clear.

The present invention has been made in order to solve the problems of the prior art as described above, and therefore, an object of the present invention is to allow multiple programs located at optically separated locations in terms of addresses to remain as actual programs. An object of the present invention is to provide an automatic computer program creation device that can be monitored at the same time.

The main point of the configuration of the present invention is that it has at least a central processing unit (hereinafter abbreviated as CPU), a display device, an input device, an output device, and a storage device, and that the computer log 2 is configured according to information input from the input device. In the automatic computer program creation device, the created program can be displayed on the display device and can be outputted via the output device. In addition, we have set up an auxiliary area,
The present invention is characterized in that it includes means for simultaneously monitoring programs in a plurality of areas that are discontinuous in terms of program addresses in both areas.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 5 is an explanatory diagram of a CRT screen in one embodiment of the present invention. In the same figure, 101 is a CRT screen, 102 is a ladder area, 103 is a setting area, 104 is a reference book area, 105 is an auxiliary monitor area for performing computer monitoring,
It is.

In FIG. 5, before multi-monitoring is specified, area 105 is in a blank state.

Output 10 while motoring the status of ladder area 102.
0.2, the output 100.2 is displayed in the auxiliary monitor area 105 and at the same time starts monitoring this portion. That is, both the ladder area 102 and the auxiliary monitor area 105 will be monitored.

FIG. 6 shows the display of various symbols within the auxiliary monitor area. As shown in (a) and (a), A contact, B
The contact output monitor is the same as the normal ladder area monitor, as shown in (C) and (2).
C and SR are designed to allow you to monitor the Autumn Equinox card. Here, the black b mark is ON, and the blank is O.
Indicates FF state. (E).

As shown in (v), TMR is used for timers and counters.

The card number is shown to the right of CTR, and the set value, current value, and UP signal are shown in order to the right of DS.

FIG. 7 is a flowchart showing the processing procedure when performing multi-monitoring. First, after monitoring the normal ladder area, if an auxiliary monitor is specified, the auxiliary monitor area is also monitored. Now both the ladder area and the auxiliary monitor area are monitored, and multi-monitoring is performed.

According to this invention, an auxiliary monitoring area is provided in the Progera B automatic creation device, which previously could only perform program monitoring within a limited, continuous range. This has the effect of making it possible to monitor
