Hi guys,
my first message since I register. Sorry to not helping you efficiently while. I need help now.

I am trying to communicate X2Base HMI with Danfoss FC51 inverter via RS485 at Comm Port 4 in HMI. But not going further then Illegal Address Station xx or Illegal Function station xx.
Danfoss manual shows that (attached file communication settings starts at 71 to 82 pages) parameter registers addresses 10 x par. number and at another chapter says -1.
I assume out of it if you want to access parameter 3.20 you need to reach [(10 x 320)-1]+40000. I tried 40320 beijer gave me illegal address station 1 and I tried 40319 illegal function station 1

most combinations of beijer communication settings have been tried by me. But couldnt find any solution. If anybody have any idea will be
appreciated. Thanks in advance.
