When I Transfer The Program To CPM1A PLC Using The SYSMAC Support Software, A Message Saying To Turn ON The PLC’s DIP Switch And Try Again Was Displayed. Why?

The default CQM1 PLC function codes for expansion instructions must be used on the CPM1A. They cannot be changed. The message will appear if the function code for any of the eighteen expansion instructions has been changed when a program is transferred.

If this message appears, return to the CQM1 default function codes for expansion instructions and use them in programming.
