NORDAC frequency converter changes/differences in parameters between 5xxE and 5xxP series

There are some subtle differences between Nord frequency converters from the 500e and 500p series. I.e. changing from 530e to NORDAC PRO 550p needs different register. Unfortunately I had no changelog from the manufacturer.

The reference documents are BU 0500 and BU 0600 respectively. I found no good way discerning the models apart from reading the parameter 742 = Data base version.

s= Supervisor
P= Parameter Set dependant
Arr = Array Parameter
V = Simple (V)alue, i.e. word/dblword

Nota: This list might be incomplete!
