Manufacturer specific object channel (from PNU 1600)
With PNUs>1600 you can programm each ASCII-parameter/command of the AX2000/2500. The
PNU can be calculated by the object number with a specific offset (ASCII command reference list:
DPR).
All PNUs described in this manual can be reached with index=1. In the ASCII reference list you find
for every parameter the PNU and the referring index. More functions of the object channel can be
used with the indices listed below.
The offset and the indices that must be used depend on the object number:
