(2) Operation when the operating status is changed from STOP to RUN
(a) Previous state (Default)
The CPU module outputs the output (Y) status immediately before changed to the STOP status and then
performs sequence program operations.
(b) Recalculate (output is 1 scan later)
All outputs are turned off.
The CPU module outputs the output (Y) status after sequence program operations are completed.
For the operation of the CPU module when the output (Y) status is forcibly turned on in the STOP status, refer
to Page 126, Section 3.4 (4).
