I hope you dont mind if i hijack this topic.
I have a problem, i have 2 of the same ABB modbus energymeters B21 212 00, the first adres is still working for a half year.
multiple times i try to add a second energymeter.
I address him 2 and so far i know all other settings of the modbus are the same.
I had more of the energymeters and i also tried others with the same settings and adres 2.
but the problem is, the Wiser still contue give problems 'in the error log is see 'Airco (RTU 1 slave 2) read failed: Operation timed out'.
but it looks like it is also working sometimes.
The total cable lengte is a 50cm (KNX kabel) and the wires are twisted under the terminal, to proceed to the 2nd module, so im sure it isnt the cable.
Do you have a idea where i have to look to solve this problem?
