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:
• Remote RUN/STOP
• Remote PAUSE
• Remote RESET
• Remote latch clear
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/RESET switch of the CPU module in the RUN position.
(2) Application
This operation is useful in the following cases.
• When the CPU module is inaccessible
• To run or stop the CPU module in a control panel externally
(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.)
