REMOTE OPERATION
A remote operation is an operation to externally change the operation status of the CPU module with the RUN/STOP/RESET
switch of the CPU module set to the RUN position.
The following items show the types of remote operation.

• Remote RUN/STOP

• Remote PAUSE
• Remote RESET
11.1
Remote RUN/STOP
This operation externally changes the CPU module to RUN/STOP status with the RUN/STOP/RESET switch of the CPU
module set to the RUN position. It is used to reach a CPU module in an inaccessible place or in case of changing the status of
the CPU module in the control box to RUN/STOP status with an external signal.

Applications of remote RUN/STOP

It is usable in the following cases.
• When the CPU module is in an inaccessible place
• When changing the status of the CPU module in the control box to RUN/STOP from outside

Operation during remote RUN/STOP

In case of remote RUN/STOP, the operation of the program is as shown below.
At remote STOP
A program is executed up-to END instruction and changes to STOP status.
At remote RUN
When remote RUN is executed in the STOP status, once again the CPU module turns to RUN status and the program is
executed from step 0.

Method of execution of remote RUN/STOP

The following are the methods of execution of remote RUN/STOP.
Contact method
Set the RUN contact in the parameter. The allowable device range is X0 to X17.
Execute remote RUN/STOP by contact ON/OFF. Set the correspondence of ON/OFF and RUN/STOP operation of the contact
in CPU parameters.
• When set to RUN at contacts ON
When contact is set to OFF, the CPU module is in the STOP status.
When contact is set to ON, the CPU module is in the RUN status.
