(4) 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.
