37.2.15 Individual operation for RUN/STOP input [M8035 to M8037]
When using external push button switches to control the PLC's RUN/STOP mode, operate the switches using
the following procedure.
The PLC enters RUN mode by one-shot input of the RUN switch, while one-shot input of the STOP switch
drives the STOP mode.
1. Program example
The figure on the left shows an example
for the FX
3U
PLC (sink input).
2. Setting method
1) Turn the built-in RUN/STOP switch to STOP.
2) Set up the RUN input switch, (X) (X000 is specified in the circuit diagram example above.)
Make the external RUN/STOP input valid by specifying an input between X000 and X017
*1
for the RUN
input signal.
