Software Switches 1

Use one of the following device variables for CJ-series Unit is used to operate Software Switches 1 from
the user program:
• WORD-type device variable for CJ-series Unit holding all switch functions contained in Software
Switches 1
• BOOL-type device variable for CJ-series Unit separating functions per each switch contained in Soft-

All switches execute some functions when the user changes them to TRUE. They change to FALSE
automatically after the functions are executed.

• *_Sw1IOCommStopCmd (Remote I/O Communications Stop Switch)
Note No functions other than the master and slave communications are disabled by stopping master
or slave communications.
If multiple switches are changed to TRUE simultaneously, the requests will generate errors and Unit
operation will remain unchanged.
The device variables for CJ-series Unit corresponding to the following words will change to TRUE if a
