IncreasingSegment-timeinSoakSegment
The remaining segment time from the time when the hold state is released can be
changed during the hold operation.
When the remaining segment time is changed in the soak segment and the hold state is
released, the program pattern operation restarts from the changed segment time.
When the segment time is decreased, the segment time and the time of the time event
are shortened by the decreased amount of time.
When the on time or off time of the time event is larger than the changed remaining
segment time, the program works according to the changed remaining segment time.
