I have a S7- 1214 CPU connected to a Sentron PAC 3100 via Modbus RTU.
I am trying to access
Total active power
Total reactive power (VAR1)
How do i set up a DB to monitor the values in these registers?
How do i reference the register in the PAC that holds this data? (i.e. what part of the DB do i access?)
Thank you for your help
