14 PLC Help Function

14.1 Program Format Switch

Interaction between G code and PLC I/F methods

There are two type of means to switch the program format: G code method (G188/G189) and PLC I/F method (ON/OFF of

PFCHR). After you have switched the program format using one of the methods, you can execute cancel of this format switch

using another method.

During automatic operation, Program format switch in progress signal (PFCHS: XCF0) is dynamically changed by G188/

G189. However, after automatic operation is finished, the signal follows the state of Program format switch request signal

regardless of the state at the completion of automatic operation.

(Example) You start automatic operation with PFCHR ON, and then issue G189, which turns OFF PFCHS (Switch cancel

status). After the automatic operation is finished, however, PFCHS turns ON (Switched status).
