(1) Output (Y) Status when changing from STOP Status to RUN Status
When changing from RUN status to STOP status, the RUN status output (Y) is
stored in the sequence and all the outputs (Y) are turned OFF.
The state after transition from STOP to RUN can be selected from the following
two options with the Basic model QCPU.
• The output state prior to STOP is output.
• The output is cleared.
(Default: After transition from STOP to RUN, the output (Y) state prior to STOP
is output then the program is executed.)
(a) Previous State
After the output (Y) status before the STOP status is output, the sequence
program calculations are performed.
(b) Recalculate (Output is 1 Scan later)
Clears all output (Y) and outputs the output (Y) after executing the
sequence program calculations.
