Running and Stopping Procedures [Power ON]
14.2.1 Methods of running and stopping
FX
3U
PLCs can be started or stopped by any of the following three methods.
Two of the methods can be combined.
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 of the main unit (X000 to X007 on a 16-point type unit) can be used
as a RUN input terminal by a 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.
→
For details, refer to "Kinds of Parameters and Settings" in Programming Manual.
Operation with two switches (RUN and STOP)
The PLC can be started and stopped with individual RUN and STOP pushbutton switches.
For this operation, a sequence program using M8035 to M8037 is necessary.
→
For details, refer to "Operations of Special Devices" in Programming Manual.
3. Starting and stopping by remote control from programming software
The programming software 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.
The remote operation for starting and stopping from the programming software is used in combination with
the built-in RUN/STOP switch.
