SEQUENCE PROGRAM CREATING PROCEDURE
The procedure for creating the sequence program when the CNC machine
tool is controlled by use of the PMC is shown in Fig. 1.
Proceed according to the flow shown in Fig. 1.
The procedure is briefly explained below.
Decide the control object (machine, CNC)
Decide the specifications of control
operations
D Calculate the number of DI/DO points
D Estimate the control scale
Create the interface specifications
DI/DO terminal allocation
Store the sequence program into the PMC
RAM board by using the keys of the
CRT/MDI
If necessary correct with the keys of the
CRT/MDI
Create the ladder diagram
Create the addrss table
Entry method of the
sequence program
Specification of the
programmer
Is there a simulator?
Debug the sequence program with the
simulator
Should the program be
corrected?
Enter the sequence program with the offline
programmer key
When the debugging connect the offline
programmer to CNC and transfer the
sequence program to Debugging RAM
In necessary correct with the offline
programmer key
Start of control system
