Caution
(a) Note the following points because the A2CCPU gives priority to the
STOP command.
1) The A2CCPU is set to the STOP state when the STOP command
is given from the remote RUN contact or a peripheral device.
2) To set the A2CCPU from the STOP state back to the RUN state,
it is necessary to set all external factors (remote RUN contact,
peripheral device) which caused the remote STOP to the RUN
state.
