You might want to review the document "MODBUS RTU RS 485 add-on module for USM II transmitters". It appears to be document # FDK:521H1183. It covers the use of the MODBUS RTU add-on module, product code number FDK:085U0234, that can be used in the Siemens Flow Instruments USM II family of transmitters, which includes MAG 6000. The add-on module makes the Mag 6000 into a Modbus RTU slave on a 2 wire RS-485 network. A Modbus master sends a 03 read instruction/command/function code (read holding register) requesting data from registers 43002 and 43003. The slave returns the contents of those registers, a floating point (real) value that is the absolute volume in m3/Sec.
