ABB · PUBLIC DEVICE MAP
A44 Modbus register map
Core read-only instrumentation block from the official A44 Modbus mapping. Register addresses are the hexadecimal protocol offsets stated by ABB.
2 groups, 26 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 2CMC484001M0201 Rev E 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.
