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 Development Protocol 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.
