Similar problem described (with Siemens PAC3200 power monitor) here:
inductiveautomation.com/forum/v … 97b#p35869
I have PAC4200 configured in gateway (says that the device is connected).
Tried different ways, but all I get is a tag with unknown quality and NULL value.
Can someone give advice how to read tags from PAC4200 using Modbus TCP driver?
