Remark: Unity priority - stepL Priority
The first digit of the Master Slave Priority refers to the Unit priority. With this digit you can give
each unit a certain start up priority.
The second digit refers to the Step Length priority. This setting reacts only on load up steps
and avoids that one of the DICN units goes into freeze-up alarm because the common
leaving water is still to high.
