Siemens SENTRON PAC2200 Modbus register map

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.

Protocol
Modbus TCP (Ethernet versions) or Modbus RTU (RS485 versions)
Defaults
Modbus TCP port 502 (setting range 0 to 65534). Modbus RTU (RS485 versions only): address 126 (range 1 to 247), 19200 baud (4800, 9600, 19200, 38400, 57600, 115200), format 8N2 (8N1, 8N2, 8E1, 8O1), response time 0 ms (all p. 81 to 82). DHCP is on at the factory. Function codes supported: 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x0F, 0x10, 0x14, 0x2B (p. 103).

Address base. NOT proven by the manual. The manual lists an Offset for each value (the first voltage is offset 1, a two-register value starts at each odd offset), does not state how the offset maps to the Modbus start address, and prints no example frame. Zero-based (wire address = printed offset) is an assumption, supported only indirectly: the offsets match those of the SENTRON PAC3200 (for example voltages at 1, 3, 5 and total active power at 65), and Siemens' S7-1200 application example for the PAC3200 (Entry ID 40614428) reads total active power at 40001 + 65, which is holding register 65 in zero-based terms. That example is for the PAC3200, not this device. Counter-evidence: in the file-record tables (function code 0x14, p. 110 onward) the manual prints offset 1 next to the address 30001 and offset 257 next to 30257, which read as one-based Modicon numbers, but those tables are a separate record layout and do not prove how Table A-3 offsets map. If values look shifted by one register on the PAC2200, read 2 registers from offset 1 and compare with the display. A read that starts in the middle of a multi-register value returns an exception, as the manual states. Registers marked area coil are the bit parameters of Table A-6 (function codes 0x01, 0x02, 0x05, 0x0F); the manual prints them with 0 registers and does not say whether their offsets are coil addresses counted from 0 or 1, so the same offset assumption applies. Address 1 in the manual is address 1 on the wire.

Word order. The manual does not state the word or byte order of the 32-bit unsigned long, 32-bit float and 64-bit double values (it states big endian only for the object ID used with function code 0x14). Read each value from its own start offset with the full number of registers. The manual lists the same energies a second time as 32-bit floats at offsets 2801 to 2883, but prints inconsistent units for that block, so only the 64-bit double block at 801 to 965 is listed here. The current period values at 545 to 597, the file-record data (function code 0x14, A.1.4 to A.1.6) and the user-defined function 0x64 are not listed.

Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

Scale is the number to multiply the raw value by to get the unit. Types with more than one register (32 and 64-bit) follow the word order above.

Open in Modbus Poll

  1. Download the Modbus Poll blocks file.
  2. Open Modbus Poll, connect to the device and set its unit ID. The manual does not state the word order for 32-bit values. Check one known value (a voltage or a counter) and switch the setting if it reads wrong.
  3. In the blocks panel on the right, click Import CSV and pick the file. CSV import is a Pro feature. Without Pro, Modbus Poll polls the first 20 values of your blocks.
  4. The wire addresses are already in the file, so there is no 0-based or 1-based conversion to do.

Once the values look right, export the tag list to Ignition, Kepware, Node-RED, Home Assistant or Voltrus SCADA.
