Schneider Electric EasyLogic PM1200 Modbus register map

Three-phase digital power meter, the Modbus RTU model of the EasyLogic PM1000 series (the PM1000 has no communications). It reports current, voltage, power, power factor, frequency, THD, demand, energy integrators, run and on hours and power interruption counts, and its setup values can be read and written over RS-485.

Protocol
Modbus RTU
Defaults
Table 6-5 lists Modbus RTU, 8 data bits, even parity, 1 stop bit and device address 1 (valid 1 to 247), with a baud rate of 9600 (user range 4800 to 19200). The setup block (Table 6-22) lists a default baud code of 5.0, which is 19200, so confirm the baud rate on the meter.

Address base. The manual prints decimal addresses such as 3901 for apparent power total (VA) and says some SCADA software uses a Modbus register address instead: add 40000, giving 43901. Its master software table (Table 6-7, p. 50) then lists 43901 for most PLC and SCADA packages and 3900 for the Siemens PLC and ABB Microscada entries, so wire address = printed number minus 1. Function code 03 is used for reads and 10 (hex) for writes. Values in the 'block only' rows must be read or written as the whole block stated in the note. The manual lists the OLD integrated blocks (Tables 6-18 to 6-20) one address above the forward, reverse and total blocks (for example 3122 against 3121), which overlaps the two register floats, so those rows are not included here. For example 85 in the manual (Model, options and version number) is address 84 on the wire.

Word order. All readings are 32-bit values over two registers. The manual describes the float byte order only through the setup parameter F.SEQ (register 141): 4321 for big-endian and 2143 for swapped big-endian, with a default of 2143, and through the test value 4030201.0 at register 320 that a master writes and reads back to check the byte order. Table 6-7 also tells some masters (ION Enterprise) to use a swapped float and Modscan to use unswapped floating point mode for the same register. The manual does not say which register carries the high word, so check against the meter before relying on it.

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

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.
