6.6 Remote Operation
6.6.1 Remote RUN/STOP
6.6 Remote Operation
Remote operation allows to change the operating status of the CPU module externally (by GX Developer or external
devices using the MC protocol, with link dedicated instructions of the CC-Link IE Controller Network module or
MELSECNET/H module, or using remote contacts).
There are four types of remote operations:
6.6.1 Remote RUN/STOP
(1) Definition
This operation changes the operating status of the CPU module externally to RUN or STOP, keeping the RUN/
STOP switch of the CPU module (the RUN/STOP/RESET switch for the Basic model QCPU) in the RUN position.
(2) Application
This operation is useful to run or stop the CPU module remotely when:
• the CPU module is inaccessible, or
• the CPU module is in a control panel.
(3) Program operation
The program operation will be as follows when the remote RUN/STOP operation is performed.
(a) Remote STOP
The CPU module executes a program until the END instruction and changes its operating status to STOP.
(b) Remote RUN
The CPU module changes its operating status to RUN and executes a program from the step 0. (The remote
RUN operation must be performed to the CPU module whose operating status has been changed to STOP by
the remote STOP operation.)
