Software Switches (*_SwCmd)

The PROFIBUS-DP communication status of CJ1W-PRT21 can be controlled through the first CIO
word (device variable *_SwCmd) allocated via the Machine No. setting. The communication status set
by these bits is retained until the Unit is restarted (Power-on or reset). After a restart, PROFIBUS-DP
communication is enabled by default.
