Parameter Group Number (PGN)
The Parameter Group Number is an identifier for parameters.
The following PGN's are supported:
PGN 60928 (Name-Field)
PGN 61184 (Encoder Parameters)
PGN 65450 (cyclic process data)
Calculation of Parameter Group Number (PGN):
PDU1 Format:
PGN = "PDU Format Field" * 256 + 0 -> Only every 256 PGN number exist.
PDU2 Format:
PGN = "PDU Format Field" *256 + "Group Extension value"
