When automatic refresh of intelligent function modules is set, communication with the
intelligent function modules of the designated data is performed.
Refer to the manual of the intelligent function modules, for details on the automatic
refresh setting of intelligent function modules.
This is a post-processing to return the sequence program execution to step 0 after
completing the whole sequence program operation processing once.
(a) When a refresh request is made from the network module, refresh
processing is performed.
(b) When the trace point of the sampling trace is set at every scan (after END
instruction execution), the set device status is stored in the sampling trace
area.
POINT
(1) When the constant scan function (See Section 7.2) 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.
