PLC subroutine library

6.6.1

Overview

In order to simplify the PLC design, we provide refined PLC functions which have generality, such as initialization, machine
panel signal processing, emergency stop processing, axis enable control, hard limit, and reference point etc. By adding the
desired subroutine module to the main procedure, plus other supplementary procedures, you can complete the PLC
procedure design easily.
The PLC subroutine library consists of the following files:
● PLC project file: SAMPLE_TURN.PTP (application program as examples for a turning machine)
● PLC project file: SAMPLE_MILL.PTP (application program as examples for a milling machine)
Note
Through these examples, you can clearly realize how to create or invoke PLC subroutines. You can reorganize PLC
subroutines or modify networks to realize most machine functions, test and debug subroutines of the library.
