In addition, - Bus (B) of the PC main body A further includes a system program 6 and an I10 interface circuit 8.
is connected, and this I10 interface circuit 8 is connected to I1
0 port 9.

The programming console 10 displays transmit/receive signal data input through the interface circuit 5, which instructs the operation of the key operation procedure program, on the display section 11.
It is further provided with a key operation section C which is an automatic operation command section for outputting an operation command signal of an operation procedure desired by the user to the MPU 2.

As shown in FIG. 2, this key operation section C is provided with a FUN key, numeric keypad, clear key, shift key, channel key (CH), HR main key monitor key, etc. In this embodiment, an operation command signal press the FUN key, then press the number 6-4 on the numeric keypad, the 6th
A series of seven key operations up to the clear keel monitor key shown in the figure are automatically performed according to the contents of the DM shown in FIG.

That is, when the user operates the key operation section C of the programming console (hereinafter referred to as the programmer) 10, the PC main body A operates, and when the contact point 0000 in the ladder diagram of FIG. 8 rises, for example, as shown in a, When the FUN key and the numeric keypad 6.2 are pressed in sequence to specify an operation command on the program controller 10 that specifies the address DM100O, which is the system setting area of the program controller key operation automatic program in the user program memory 4, an address as shown in FIG. 7 is specified. The operating procedure is retrieved and written into a memory area of the RAM 3 under the control of the MPU 2, and the MPU 2 is configured to execute various controls on external equipment via the interface circuit 1 based on the written program.

Note that Figures 10 and 11 are for LR45C, respectively.
FIG. 4 is an explanatory diagram illustrating a display state displayed on the display unit 11 of the pro-computer 10 when monitoring TiM511 and a display state of the display unit 11 of the pro-computer 10 when monitoring TiM511.

In addition, the PCC main body of this embodiment counts the transmitted/received signals inputted to the communication interface circuit 1, inputs them as character signals to the input/output RAM 3, and transmits/received signal data from the program controller 10. If there is an output request, the transmitting/receiving signal data stored in the RAM 3 is output-controlled, and the transmitting/receiving data is output to the processor 10 via the interface circuit 5.

Next, the operation of the PC of the present invention in this embodiment will be explained based on the flowcharts of FIGS. 3 to 5.

During normal operation of the PC of the present invention, as shown in FIG.
0, human output control of the MPU 2 is performed based on the program set in the RAM 3, and the process moves to the next step 101.

In step 101, a service is provided to the processor 10 via the communication interface circuit 5 under the control of the MPU 2.

Then, the service to the program controller 10 is performed, and the execution status of the service is displayed on the display unit 11 of the programming console 10. When the service is completed, the process moves to step 102, and other services other than the program controller 10 are Tool service is provided to the peripheral device via the interface circuit 5, and the process moves to step 103.

Then, when the upper link service processing is performed in step 103, the process moves to step 104, where the RAM 3 is refreshed, a series of processes are completed, and the process returns to step 100 again to repeat the above steps.

Next, details of the professional control service processing will be explained.

First, in step 201, the MPU 2 searches for a key input check process from the processor 10, and in step 202, if a key input has been made from the key operation section C of the processor 10, the MPU 2 makes an affirmative determination (YES). Then, the process moves to step 203.

Then, after transaction processing is performed by the MPU 2 in step 203, the process moves to step 204, where a program for operating the program controller 10 is executed under the output control of the MPU 2, and when it is completed, the process returns to the original step 2.
The process returns to 01 and the above steps are repeated.

If the MPU 2 determines NO in step 202, the process returns to step 201 and executes the key input check process in step 201 again.

Furthermore, key input interruption of the processor 10 will be explained based on FIG.

First, the key operation unit C of the processor 10 is operated, for example, in this example, the FUN key and the numeric keypad 6.4 are pressed, and an automatic operation command of the processor 10 is input to the MPU 2.

Then, the process moves to step 300 and the key code is M.
The PU 2 transfers the program from the user program memory 4 to the RAM 3 and stores it in a setting area provided in the RAM 3 as shown in FIG.

When the storage of the operating procedure program in the RAM 3 is completed, a return operation is performed so that the key input by ~1PU2 is performed again, and the series of operations is completed.

That is, for example, if the relay No. 0000 of the program shown in FIG. 8 written in the user program 4 is made conductive while the data shown in FIG. The MPU 2 transfers the data from DM 100O to just before the delimiter ($00) to the RAM 3 as shown in FIG.

After this, when the control operation of the MPU 2 shifts to the program control service process, the key input check process indicates that a key input is present, executes all the data stored in the RAM 2, and when it is finished, as shown in FIG. 10. to LR4
5 is displayed on the display unit 11 of the processor 10.

From this point on, the processor 10 continues to display the contents of the LR45CH from the display section 11.

This state continues until a new transaction is entered by the next key input from the key operation section C of the processor 10 or by a processor key operation command.

As is clear from the above description, according to the PC of this embodiment, in addition to the user program, the PC side has an operation procedure writing area in which the operation procedures of the program controller described in 1. Program 4
and a RAM 3, and a key operation section C, which is an automatic operation command section for instructing the operation procedure written in the operation procedure writing area, is provided on the procon 10 side.
The operation of the PC main body A is automatically controlled based on the operating procedure of the pro-computer 10 by simply operating the key operation part C provided in the pro-computer 10, and even those who are not familiar with the operation of the pro-computer 10 can easily operate it. The ease of use will be improved, as the professional computer 10 can be used as an operation box.

(Effects of the Invention) As is clear from the above configuration, according to the PC of the present invention, the PC side has an operation procedure writing area in which the operation procedures of the blockraming console are written in addition to the user program. The user's programming console is equipped with an automatic operation command section that commands the operation procedure written in the operation procedure writing area, and the program is automatically executed simply by operating the automatic operation command section provided on the programming console. The PC's operation is controlled based on the operating procedures of the programming console, and it can be easily used even by people who are not familiar with the operation of the programming console, and the programming console can be used as if it were an operation box, improving usability for the user. This has the effect of reducing costs in addition to achieving improved performance.
