A parameter set changeover function involving 8 different parameter sets has
been implemented. The request is made via the PLC. They are predominantly
controller and filter data that can be switched over as a function of parameter
set.
Data which are assigned to specific parameter sets are identified by an [n] in the
string code.
Parameter set assignments can be found in the parameter table (Section 4.15)
in the "Attribute index" column with entries 0...7.
