SDM220-Modbus register map
Conservative core measurement subset transcribed from the official SDM220-Modbus Modbus documentation.
2 groups, 11 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 V1.1 and the installed device before commissioning.

SOURCE & SCOPE
Import the map, then verify the device.
The catalogue provides register metadata, not a connection profile. Serial port, Unit ID, baud rate and site-specific naming stay in your Busloom project.
