8.8.3 Incremental Dimension Number 255
Incremental dimension number 255 also allows you to set the distance.
You transfer the switch-off differences and the switchover differences together with
the incremental dimension. In contrast to the other incremental dimensions,
incremental dimension 255 uses the value for the switch-off and switchover
difference specified in the channel DB. The entries from the machine data have no
validity for this incremental dimension.
