Note the following points since the built-in PLC function gives priority to STOP.

•The built-in PLC function enters the STOP status when remote STOP is performed from any of the remote RUN contact, GX Developer, etc.

•To place the built-in PLC function in the RUN status again after it has been put in the STOP status by remote STOP, all external factors (remote RUN contact, GX Developer, etc.) for remote STOP must be set to RUN.
