The NLON-01 adapter has downloadable applications for different drive types, with the default application in the adapter being for ACS600. If the application is not correct for the drive and the NLON-01 has been configured with a network management tool, the POW/ERR LED on the adapter will blink between red and green at a rate of 1 Hz. The appropriate application file to be loaded depends on the tool used. Most network management tools can download the application, but current versions of The Trane Company's Rover tool and Tridium's tool cannot. Like all DDCS fieldbus adapters, parameter 5005 must be set to DDCS (or Modus + DDCS) to enable communication between the adapter and the drive. When DDCS communication between the NLON-01 and ACH400 is working, parameter 51.01 should show 7. Parameters in group 51 are read-only values and manually changing them has no effect on the NLON-01.
The document is a Frequently Asked Questions (FAQ) guide for the ABB NLON-01 LonWorks fieldbus adapter used with ABB drives. It explains how to load the correct application files, configure network variables, and resolve common communication and operation issues.
Key topics include adapter connection problems, selection of *.XIF files for different network tools, start‑command handling, reference and scaling variables, intermittent communication caused by electromagnetic interference, and drive behavior after LonWorks network installation.

Use files ending with ‘a’ for Windows‑API based tools and files without ‘a’ for LNS‑based tools; LNS tools are the most common today.
