10.6.6 Relationship between remote operation and CPU module RUN/STOP key switch
Using the combination of the remote operation and the RUN/STOP key switch of the CPU
module explained in Section 10.6.1 through Section 10.6.5, the operating status of the
QnACPU is determined as follows.
*1 If performed using a remote RUN contact, beforehand set "RUN-PAUSE contacts" in the PLC
system in parameter mode.
*2 If performed using a remote PAUSE contact, beforehand set "RUN-PAUSE contacts" in the
PLC system in parameter mode.Furthermore, the remote PAUSE enable coil (SM206) has to
be turned ON in advance.
*3 "Remote reset" field in the PLC system has to be set to "Allow"in parameter mode.
*4 The operation status can be RESET if the CPU module is stopped by remote operation.
When the RUN/STOP key switch is set to RUN and multiple remote operation requests are
received, the CPU module first performs the operation with the highest priority.
The order of priority increases from (4) to (1).
