We are trying to use PFC200 to read from 750-457 +/- 0-10VDC and write to 750-557  
via mosquito MQTT.  
One error is this:

and another is that WAGO I/O check suddenly says “node not confguered bla bla” and produce an error code that cant be found on WAGO.  
Any one have a clue why we have the /var/run/dbus/system\_bus\_socket problem?  
Coold restart of PFC doesnt seem to solve the problem.

Chers

Hello, what version of FW are you using, and are you using the docker version of the daemon? Perhaps try an older FW, like 18 or 19.  
Another option is to use the Modbus Daemon docker container.
