(3) Precautions
(a) Take note of the following, because STOP has priority in Basic model
QCPU:
1) The Basic model QCPU enters the STOP state when remote STOP is
performed from remote RUN contact, GX Developer function, or serial
communication module.
2) When Basic model QCPU is set to the STOP state with remote STOP,
all external factors which performed a remote STOP (remote RUN
contact, serial communication module, etc.) must be set to RUN.
REMARK
The RUN/STOP state is described below:
• RUN State .................State which repeatedly executes the calculations from step 0
• STOP State ...............State where the sequence program calculations are stopped
to the END instruction in the sequence program.
and the output (Y) is all OFF.
