Siemens PAC4200 Modbus register map

Also searched as: SENTRON PAC4200 · 7KM4212-0BA00-3AA0 · 7KM4211-1BA00-3AA0

222 Modbus registers of the Siemens PAC4200, with the address on the wire, the 30001-style reference, data type, byte order, unit and scale. Transcribed from SENTRON PAC4200 Power Monitoring Device System Manual (05/2019).

SENTRON PAC4200 power monitoring device; measurements are 32-bit floats, energy counters 64-bit floats.

Connection notes

  • Addresses are the manual's offsets, sent unchanged (the convention mbmd's working PAC2200 driver uses).
  • Function code 3 or 4 reads the same registers; reading from the middle of a multi-register value is refused.
  • Modbus TCP is built in; Modbus RTU needs the PAC RS485 expansion module.
  • Measured variables with a time stamp, minimum/maximum logs and the configuration settings are not in this map yet.

Read it by name

Read the PAC4200 with an AI assistant

The Proxus Industrial MCP Server includes this map. Set it on the device, and Claude, Cursor or VS Code reads registers by key with the right type, byte order, scale and unit. It only reads.

Ask your assistant

Read voltage_l1_n, voltage_l2_n, voltage_l3_n from pac4200-1.

The tool call it makes

read_named(device: "pac4200-1", keys: ["voltage_l1_n", "voltage_l2_n", "voltage_l3_n"])

Have this device? Verify the map.

Ask your assistant to run verify_device_map. It reads every register once, read-only, checks that the values are plausible and asks you to compare two values with the display. You get a report and a prefilled GitHub issue to submit; your name goes on this map’s verified list.

How verification works

Collecting from many devices?

Proxus reads Modbus TCP and RTU devices next to the machines, keeps the history and delivers the values to dashboards, databases and AI.
