Fixed Time Rotational Sequence

The moment of automatic sequence rotation can be pre-defined for day and hour (on a daily, weekly or monthly base), adjusted by parameters CYC-03, CYC-04 and CYC-05. With parameter CYC-03, the period of automatic sequence rotation is selectable. The rotation will change the sequence by position 1, independent of runtime data. If the sequence order was 1, 2, 3 before the sequence rotation, then the order will be 2, 3, 1 after the sequence rotation.
