The BMENOR2200H module provides very useful diagnostic information in various ways such as LED’s, webpage, etc., and one of the ways to get module diagnostics is via Modbus/TCP. The module is acting as a Modbus Server and stores all the diagnostics information in the addresses and this information can be retrieved by any Modbus client such as (Control Expert, SCADA, any Modbus Client).
