Abstract

PURPOSE:To prevent the runaway due to an error of a sequence program by connecting a target machine to an off-line programmer and carrying out the transfer of data by an on-line dynamic display instruction included in the sequence program. CONSTITUTION:A sequence program 21 produced by an off-line programmer 20 is transferred to a PMC 13 of a target machine 10. The machine 10 carries out the received machine 10. The PCM 13 stores the input/output signal as a transfer input signal 15 to be applied to the programmer 20 as long as an off-line dynamic display instruction 22 is included in a sequence program 14. Thus the signal 15 is sent to the programmer 20. The programmer 20 carries out the sequence program and performs a bugging job.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an offline execution method for a PC, and more particularly to an offline execution method for a PC in which a target machine and an offline programmer are combined to execute a sequence program.

[Conventional technology]

In order to depack a sequence program for a numerically controlled machine tool, etc., a method is adopted in which the sequence program is actually connected to the target machine and checked before the program is completed, or the sequence program is checked only using an offline program.

[Problem that the invention seeks to solve]

However, if the program is directly connected to the target machine for debugging, an error in the sequence program may cause the target machine to run out of control, causing damage to the target machine or endangering the operator.

In addition, when debugging with an offline programmer alone, the input/output signals from the outside are not perfect, so checking the sequence program when it is connected to the actual machine is not complete, and it may be difficult to operate it.

[Means for solving problems]

In order to solve the above problems, the present invention provides an offline dynamic display command to the sequence program in a PC offline execution method in which a sequence program of a PC (programmable controller) is executed offline. Offline/offline with display command
A PC offline execution method is characterized in that input/output signals are transferred from a target machine coupled to a programmer, the input/output signals are displayed on a display screen of an offline programmer, and a sequence program is executed offline. , provided.

[Effect]

Offline dynamic display instructions transfer input/output signals from the target machine to the offline programmer.

Since the programmer can check the sequence program while checking this display, it is possible to check the sequence program according to the actual operation of the machine.

Since the connected target machine is also operated while being checked by an offline programmer, it is possible to prevent a runaway due to an error in the sequence program.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a block diagram of an offline execution method for a PC according to an embodiment of the present invention. In the figure, 10 is the target
It is a machine, machine 11, numerical control device (CNC) 12
, a PMC (
It consists of a programmable machine controller). A sequence program 14 is stored in the PMC (programmable machine controller) 13 . Reference numeral 15 indicates an input/output signal temporarily taken out from the PMC 13 and stored. Conversely, 16 is an input/output signal from an offline programmer, which will be described later.

20 is an offline programmer, and 21 is a sequence program. A sequence program 21 is created by an offline programmer 20. An offline dynamic display command 22 is issued within the sequence program 21 .

24 is a display screen of the offline programmer 20;
A display 21 of each input/output signal and a sequence program 26 created in a ladder format are displayed.

Next, we will discuss the creation and debugging of sequence programs. The sequence program 21 created by the offline programmer 20 is the PMC of the target machine 10.
(Programmable Machine Controller) 13. The target machine IO executes the transferred sequence program 14. Here, the sequence program 21 and the sequence program 14 are the same.

PMC (Programmable Machine Controller) 13
executes the sequence program 14, and if there is an offline dynamic display command 22 in it, it stores the input/output signal as the input/output signal 15 for transfer to the offline programmer 20, and transfers this to the offline programmer 20. Forward.

Off-line programmer 20 displays the transferred input/output signals on display screen 25. If you want to particularly emphasize the transferred signal, you can do so by making the lines of the ladder-type sequence program thicker or increasing the brightness, as shown in 27 and 28.

Conversely, it is also possible to transfer input/output signals from the offline programmer 20 and use the input/output signals 16 on the PMC (programmable machine controller) 13 side.

In this way, the sequence program can be executed by inputting input/output signals from the target machine to the offline programmer, so the sequence program can be debugged in accordance with the operation of the machine.

In the above explanation, the PMC (programmable machine controller) built into the numerical control unit (CNC) was explained, but the PC (programmable machine controller) installed separately was explained.
The same applies to controllers) etc. Furthermore, the present invention can be applied not only to ladder-format sequence programs but also to sequence programs created in other high-level languages such as PASCAL.

〔Effect of the invention〕

As explained above, in the present invention, a target machine is connected to an offline programmer, and an offline dynamic display instruction in a sequence program is used to
Since the input/output signals within the target machine are configured to be transferred to the offline programmer, debugging can be performed in accordance with the machine controlled by the offline programmer.
