Precautions
(a) Since the STOP state has a priority in the QnACPU, pay attention to the
following points.
1) In the QnACPU, if remote STOP is performed from any one of remote RUN
contact, GPP function, serial communication module, etc., the QnACPU will
be STOP.
2) In order to set the QnACPU to RUN again after it has been set to STOP by
remote STOP, all external factors which set remote STOP (Remote RUN
contact, GPP function, serial communication module, etc.) have to be set to
RUN.
The RUN/STOP status is defined as follows.
RUN status.............. Status in which the sequence program is repeatedly
STOP status........... Status in which the sequence program operation is stopped
