Sources and notes
- Digital energy meters DMED series, Communication protocol Modbus · version I315IGB08_22, 2022-08-23 table 2
Source: Lovato Electric, "DME series Modbus communication protocol", I315IGB08_22 (2022-08-23)
- Addresses are the table addresses of the protocol, which are 1-based: the query uses the table address minus one.
- Measurements are read with FC04; 32-bit values are high word first.
- Not in this map: the maximum, minimum and average blocks (0x0400-0x0A46), commands (0x2FF0), event log, setup parameters and waveforms.
- Registers that only some models have say so in their description.
- Frequency is Hz/100 on the DMED310T2 and DMED320 and Hz/1000 on the DMED330.
