Lovato Electric DMG210 Modbus register map
Three-phase digital multimeter. Lovato's DMG Modbus protocol document says the DMG110 and DMG210 support Modbus RTU and Modbus ASCII on the RS-485 port, and its tables mark each address for the DMG110/DMG210 column together; this map keeps the addresses marked for the DMG210 and does not include the DMG300 to DMG900 or DMG6xx-only rows, the min/max/average/demand blocks or the harmonics tables.
- Protocol

- Addresses in the manual
- 1-based register numbers (wire address is the number minus 1)
- 32 and 64-bit values

- I317 I GB 02_22 (Doc. I317IGB02_22.doc), dated 07/02/2022, 41 pages, vendor hosted
Address base. The manual prints the addresses in hexadecimal (for example 0016H for L2 active power), converted to decimal here, and states that the address in the query message must be decreased by one from the address in the table. Its worked example reads active power L2 at table address 0016H with a query address of 00 15, so wire address = printed number minus 1. Reads use function 03 or 04; setup parameters use 04 to read and 06 to write and need the save to EEPROM command described in the manual. Footnote o of Table 8 says the DMG110 reads and writes parameters through a different selection scheme (registers 0x5000 to 0x5004), so the setup rows here apply to the DMG210 only. For example 2 in the manual (L1 phase voltage) is address 1 on the wire.
Word order. The worked example on p. 4 returns the 32-bit active power L2 as bytes 00 01 FB 00 = 129792, so the high word is in the first register. The manual shows no example for the 4 register (64-bit) energy counters; assume the same high-word-first order and check against the meter.
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

The register table has every column on this page. The blocks file imports into Modbus Poll. The template JSON holds the same blocks plus unit, scale and access for scripts.

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
- Download the Modbus Poll blocks file.
- Open Modbus Poll, connect to the device and set its unit ID. In Modbus Poll set Word order to AB CD.
- 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.
- 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.
