The limits within the station types are given by
hard- and software.
Verify all given limits for each required station
by going through this flow chart
For the stationtypes CI1142, CC1142, CC1143, this limit is depending on the setup of the
logical structure.
The following graph allows to find this limit depending on the estimated average number
of ELEMENTS per ZONE.
