Siemens Modbus register maps
4 devices with the register list read from the manufacturer's own manual, plus downloads for Modbus Poll.
From the manufacturer manual
- Power meters SENTRON PAC2200 Compact three-phase power monitoring device for low-voltage networks. It reports voltages, currents, power, power factor, frequency, two-tariff energy counters per phase and in total, and has diagnostics, settings and I&M identification data. Depending on the version it has an Ethernet port (Modbus TCP), an RS485 port (Modbus RTU) or M-BUS.
- Power meters SENTRON PAC3200 Panel-mounted three-phase power monitoring device for low-voltage networks. It measures voltages, currents, power, power factor, frequency, harmonic distortion and tariff-based energy counters, and has a built-in Ethernet port.
- Variable frequency drives SINAMICS G120 Modular low-voltage AC converter family from Siemens. Control units with an RS485 port (such as the CU240B-2 and CU240E-2) can act as a Modbus RTU slave and expose process data, converter data, diagnostics and the technology controller through fixed holding registers.
- Variable frequency drives SINAMICS V20 Compact low-voltage inverter with a built-in RS485 port that can run as a Modbus RTU slave. The manual gives a fixed register table (40001 to 40559) for control, status, setpoints, ramp times, PID settings, fault codes and measured values, each linked to an inverter parameter.
