3.2 FX1S RUN/STOP Control
RUN or STOP of the FX1S can be controlled by:
nThe RUN/STOP switch mounted next to the programming port.
oA standard input (X0 to X17) defined by the system parameters.
pRemotely from a personal computer or other programming peripheral.
Note:The FX1S RUN/STOP switch works in parallel with the RUN-input terminal. Please
refer to Table 3.2.
During remote operation the FX1S RUN/STOP status is determined by the most recently
operated control.
E.g. If the RUN/STOP switch is in RUN and a remote STOP is made from a personal
computer, the PLC can only be restarted with the RUN/STOP switch by first moving the
switch to STOP and then back to RUN.
