SDM120-Modbus register map
Official core FC04 measurement map for the Eastron SDM120-Modbus single-phase meter, based on protocol revision V2.4. Values are 32-bit IEEE 754 floats in normal register order.
3 groups, 21 decoded points.
REGISTER MAP
Searchable source data.
Documentation addresses are derived from the zero-based PDU address in the public definition. Convert a documentation address to its PDU offset when comparing with the manual. Confirm the map against revision V2.4 and the installed device before commissioning.
