RUN/STOP method of PLC function from an external source (remote RUN/STOP)
• Using FR Configurator2 (Developer)
RUN/STOP can be performed by operating remote RUN/STOP from FR Configurator2 (Developer).
For example, this can be used to STOP the inverter in order to rewrite the sequence program when it is installed in an
out of reach location.
FR Configurator2 (Developer)
Note
Note the following points because the PLC function has priority on STOP.
• The PLC function switches to the STOP state when remote STOP is executed from any source such as the remote
RUN contact or FR Configurator2 (Developer), etc.
• After switching the PLC function to the STOP state with remote STOP, all external factors (remote RUN contact, FR
Configurator2 (Developer), etc.) that executed the remote STOP must be RUN in order to switch the PLC function back
to the RUN state.
NOTE
• In the RUN state, the sequence program step 0 to the END instruction are executed repeatedly.
In the STOP state, all sequence program operations are stopped, and all outputs (Y) are OFF.
