37.2.14 All outputs disable [M8034]

When M8034 is turned ON, the output memory is cleared. As a result, all actual output relay contacts are turned OFF
and the PLC is operated in the image memory.

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
24V 0V
Write the above program to the PLC.
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
signal.

a) Display the parameter setting in the programming tool
In GX Developer, double-click [Parameter] - [PC parameter] in the project tree to display the dialog box.
Go to the "PLC system (1)" tab, and set "RUN terminal input."
b) Specify the input (X) number to switch from STOP mode to RUN mode.
3) Set up the STOP switch input (X)
Specify an arbitrary input terminal (actual I/O on the PLC) within the sequence program.
Refer to the program above.
4) Transfer the program and parameters to the PLC.
5) For the parameter settings to become valid, the PLC power must be turned from OFF to ON.
3. Cautions
1) When both RUN and STOP switches are pressed at the same time, priority is given to the STOP switch.
2) When the built-in RUN/STOP switch is turned to RUN, the PLC can be set to RUN mode.
However, when the STOP switch assigned to an arbitrary input is activated, the PLC will enter STOP mode. (Even
if the built-in switch is turned to RUN, priority is given to the STOP command.)
