Notes
Addresses are the hexadecimal 'Address' column of Schneider's MasterPacT MTZ Modbus communication user guide DOCA0105EN converted to decimal; that column is the address used in the Modbus frame, while the guide's 'Register' column is address + 1 (0x7CFF = frame address 31999 = register 32000). The map is the standard data set for MasterPacT MTZ circuit breakers with a Micrologic X control unit, reached over Modbus TCP through the IFE or EIFE Ethernet interface; the IFE Modbus server answers on unit ID 255 and port 502. All energy counters of the Micrologic X (32096 onwards and 22025-22056, 44401 onwards) are 64-bit integers in Wh/VARh/VAh, which this format cannot express, so they are not listed; currents, voltages, power, power factor, THD, demand, status and alarms are listed. The registers from 11743 are the IFE/EIFE identification and status block (ASCII fields, interface MAC address and serial number). Protection settings and commands (thresholds, reset, open/close) go through the command interface with function code 16 to a command register.
