10.3.2 Remote RUN/STOP control
The FX family of programmable controllers can be controlled, i.e. switched into RUN or STOP
modes and have devices monitored by use of intelligent external control devices.
These includes such items as computers, the Mitsubishi FX data access units and Graphic
Operator Terminals.
The following example utilizes a graphic FX-DU unit:
Explanation:
The programmable controller needs no special wiring
or additional programming for this example.
The only condition required is that the PLC would not
normally be in a RUN state, i.e., there is no connection
to the RUN terminal and the RUN/STOP switch on
PLC’s that have one is set in the STOP position.
The HMI should be programmed with 'SWITCH'
devices driving the three special M codes M8035,36
and 37. By activating the 'SWITCH' devices for M8035
and M8036 the PLC can be switched into a RUN state,
while driving the 'SWITCH' device M8037 will put the
PLC into a STOP state.
Example 'SWITCH' device setting opposite.
Use an 'Alternate' switch for M8035 and M8036 and use a 'Momentary' switch for M8037.
(see DU operation manual for SWITCH operation and programming)
Note: While M8035 and M8036 are ON the MPU can not be changed to STOP mode using the
RUN terminal or RUN/STOP switch. Either set M8037 ON, or reset M8035 and M8036, to
return to the normal operating state.

FX
1N,FX2N and FX2NC Remote STOP
With FX
1N, FX2N and FX2NC units, even if the RUN terminal or RUN/STOP switch is in the RUN
position, it is still possible to do a remote STOP by forcing M8037 ON.
Return to RUN by resetting M8037.
