In the programming console, the sequence program once stored in the programmable control device can be sequentially read and modified, and the modified program can be stored again in the memory of the programmable control device.

[0004]

In the conventional programming console, while the programmable control device is executing the sequence program, it is possible to monitor the operating state and display it on the display section. However, when the operating sequence program is modified and changed, the operation of the programmable control device is temporarily stopped, and the modified sequence program is rewritten to activate the device.

Therefore, when the program is modified or changed,
There is a problem that the programmable control device and its controlled object must be stopped for a long period of time. For large-scale programmable control devices and programming consoles, a large-capacity memory is provided on the programmable control device side so that the program can be modified and changed even while the programmable control device is operating, and this modified and modified program can be executed immediately. Some are However, in such a programmable control device, a memory for a source program and a memory for an intermediate language obtained by compiling the source program each require a double capacity,
The device becomes expensive.

An object of the present invention is to enable a program to be created and edited during execution of the programmable control device without burdening the programmable control device side and without increasing the size of the device. is there.

[0007]

According to the present invention, there is provided an off-line editing device for a programming console, wherein a programmable control device is executing a control program,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the appearance of a programming console to which an embodiment of the present invention is applied. The programming console 1 has a keyboard 2, a display unit 3, and a slide switch 4 for mode switching on its surface. A memory card insertion slot 7 for inserting a memory card as an external storage medium is provided on the side of the programming console 1. The programming console 1 can be connected to the programmable control device 6 by a connecting cord 5.

The keyboard 2 is provided with ten keys, function keys, keys for inputting a desired instruction code and the like. Further, the slide switch 4 can be slid up and down to switch the operation mode between a run mode and a program mode. The programming console 1 also has a control unit 10 as shown in FIG. The control unit 10 includes a CPU and RA
It includes a microcomputer having M, ROM and the like. The keyboard 2, the slide switch 4, and the storage unit 11 are connected to the control unit 10. Storage unit 1
1 has a capacity enough to store the entire sequence program stored in the programmable control device. Further, the control unit 10 is connected to the display unit 3, a memory card communication unit 12 for communicating with a memory card inserted from the outside, and other input / output circuits. Further, the control unit 10 is connected to the control unit 14 of the programmable control device 6 via the interface 13 and the connector 5 for connection.

Next, the control operation will be described with reference to the flow charts shown in FIGS. When the programming console 1 is started up, initial settings are first made in step S1. With this initial setting, the display contents of the display unit 3 are initially displayed and the contents of the display buffer and the like are cleared. Next, in step S2, it is determined whether or not the slide switch 4 has been switched from its previous state. If the slide switch has been changed, the process proceeds to step S3. In step S3, a mode signal corresponding to the state of the slide switch 4 is sent to the programmable control device side. That is, the program mode signal is transmitted when the mode is switched to the program mode side, and the run mode signal is transmitted when the mode is switched to the RUN mode side.

In step S4, it is determined whether or not the slide switch is switched to the program mode side, and in step S5, it is determined whether or not the slide switch is switched to the run mode side. If the program mode has been switched to, the process proceeds from step S4 to step S6. In step S6, a sequence program is created and edited in the program mode. It should be noted that the creation and editing of the sequence program in this program mode is usually performed while the programmable control device is stopped while sequentially communicating data between the programmable control device and the programming console.

When the slide switch is switched to the run mode side, the process proceeds from step S5 to step S7. In step S7, it is determined whether or not a command for performing offline edit processing has been input.
The offline edit process is a process of creating and editing a sequence program on the programming console 1 side while executing the sequence program in the programmable control device. Further, in step S8, it is determined whether or not a command for restarting the once stopped programmable control device is input. In step S9, it is determined whether or not a command for performing other processing is input. When a command for performing other processing is input, the process proceeds from step S9 to step S10, the process of the designated contents is executed, and the process returns to step S2.

When an instruction for performing the offline edit process is input, the process proceeds from step S7 to step S11. In step S11, FIG.
Perform offline edit processing as shown in.
That is, in step S15, it is determined whether the sequence program or the like is loaded into the storage unit 11. Further, in step S16 in FIG. 5, it is determined whether or not the sequence program stored in the storage unit 11 is transferred to the programmable control device side.

When the program is loaded into the storage unit 11, the process proceeds from step S15 to step S17. In step S17, step S18 and step S19,
Determine which program to include. That is, in step S17, it is determined whether or not the sequence program already stored in the programmable control device is loaded. In step S18, it is determined whether or not the sequence program is loaded from the memory card. Further, in step S19, it is determined whether or not a new sequence program is created. When the sequence program is loaded from the programmable control device, the process proceeds from step S17 to step S20. Step S
At 20, the sequence program stored in the storage unit of the programmable control device is read and stored in the storage unit 11. When the sequence program is loaded from the memory card, the process proceeds from step S18 to step S21. In step S21, the sequence program is loaded into the storage unit 11 from the memory card via the memory card communication unit 12. When a new sequence program is created, the process proceeds from step S19 to step S22. In step S22, the edit area of the storage unit 11 is cleared.

The sequence program stored in the storage unit 11 is edited in step S23. Further, in the case of new creation, a process of newly creating a sequence program is performed in this step S23. The sequence program created here or the modified program is sequentially written in the storage unit 11. Then step S
At 24, it is determined whether or not the created or modified sequence program is transferred to the memory card. When transferring to a memory card, the process proceeds to step S25.
In step S25, the sequence program stored in the storage unit 11 is transferred to the predetermined area of the memory card via the memory card communication unit 12. If not transferred to the memory card, the process proceeds from step S24 to step S26. Further, in step S26, it is determined whether or not the editing process is completed. Step S2 until the end
3 to step S26 are repeatedly executed. When the edit process ends, the process moves from step S26 to step S16 in FIG.

When a command to transfer the created or modified sequence program to the storage unit of the programmable control device is issued, the process proceeds from step S16 to step S30. In step S30, it is determined whether the programmable control device is in execution. If it is being executed, the process proceeds to step S31,
A stop signal is sent to the programmable control device to temporarily stop the execution. Next, after confirming that the programmable control device has stopped, step S32
Move to. In step S32, the sequence program stored in the storage unit 11 is transferred to the programmable control device.

In this way, the sequence program created or modified during execution of the programmable control device is transferred after the programmable control device is temporarily stopped. Then, when a command for restarting the once stopped programmable control device is input, the process proceeds from step S8 to step S35 in FIG. In step S35, a signal for restarting the programmable control device is sent.

In such an embodiment, the sequence program can be created and edited during execution of the programmable control device, and it is not necessary to stop the programmable control device and its controlled object for a long period of time. Further, it is not necessary to improve the programmable control device, only increasing the source program storage area of the programming console. Therefore, even in a system including a small-sized programmable control device and a programming console, it is possible to create and edit a program by offline edit processing during execution of a sequence program.

Although the execution of the run mode in the program mode is not described in the above embodiment,
Even in the program mode, it is possible to shift to the run mode by command of the function key. Also in this case, it is possible to execute the same offline edit processing as described above.

[0024]

As described above, according to the present invention, during execution of the control program in the programmable control device,
A control program can be created and edited in the programming console, and after the control program is created and edited, the programmable control device is temporarily stopped and the control program is transferred to the programmable control device side. The control program can be created and edited during the execution of the control program without increasing the size of the control program.
