Hi chi
Thanks for confirming that it should work without any changes. I guess you meant port 102, i mistyped port 502 instead of 102.
I finally managed to solve it with a firmware update on the hilscher unit, i was using an old NL-150 unit that i normally use for programming siemens PLC and the firmware was from v2.00 and way back from 2009. The minute i updated the firmware it connected and started working. Apparently V2.00 only supports PLC programming ???
The default settings now work without any changes.
thanks for your help.
regards
rohan
