Hi,

I have used Carlo Gavazzi EM24 energy meter earlier but because of long lead times I'am trying to qulify PAC2200 energy meter. I can get communication between the PAC2200 and the Wago PLC without any errors by using Unit ID=1, FC=4 then start adr.=1. If I try to read L1-N voltage which according to the manual is adr.=1(offset) and is 2 registers long (2 words) then the readout is not correct. It's '17265' in the first word and jumping up and down on the second word. I would expect 230 (*value weight) representing the phase voltage which I can see in the PAC2200 display.

Any good ideas what could be wrong.

What is the unit ID ? seems to work with anythin else than 0.

BR.
