Parameters
3.4.4 END processing
This is a post-processing to return the sequence program execution to step 0 after
completing the whole sequence program operation processing once.
(1) Operations of END processing
The END processing includes the following.
: Executed : Not executed
POINT
1. When the constant scan function( Section 6.2)is set, END processing
time result is stored until when END processing is completed or the next scan
starts.
2. When executing the low speed execution type program, the low speed END
processing starts after the all low speed execution type programs are
completed.

Note3.34
Since the Basic model QCPU and Redundant CPU cannot use low speed execution type
programs, the low speed END processing is not performed.
