Running and Stopping Procedures [Power ON]

14.2.1 Methods of running and stopping

FX PLCs can be started or stopped by any of the following three methods.
3S
Two of the methods can be combined.
The RUN/STOP switch is located under the peripheral device connector cover.
1. Operation with built-in RUN/STOP switch
Operate the RUN/STOP switch on the front panel of the main unit to start and stop the
PLC (refer to the right figure).
Turn the switch to RUN, and the PLC will start. Turn it to STOP, and the PLC will stop.
2. Running and stopping with general-purpose input (RUN terminal)
Operation with one switch (RUN)
One of the input terminals X000 to X017
parameter setting (refer to the figure below).
When the specified input terminal is turned on, the PLC starts. When it is turned off, the PLC is started or
stopped depending on the state of the built-in RUN/STOP switch.

3. Starting and stopping by remote control from programming tool
The programming tool has a function to forcibly start and stop the PLC by remote control (remote RUN/STOP
function).
However, when power is reapplied, the remote RUN/STOP function is disabled. The RUN/STOP status is
then determined by the RUN/STOP switch or RUN terminal.
For details on the start and stop procedures with remote control from programming tool, refer to Paragraph 2
of Subsection 14.2.2.
