Issue
A Niagara R2 station running on a laptop with LON integration does not communicate with MNL controllers connected through an Echelon USB-LON adapter. The station appears to be running in Admin Tool, but no controller communication occurs.
Product Line
TAC IA SeriesEnvironment
- Niagara R2
- Echelon USB-LON adapter
Cause
WorkPlace Tech and Niagara R2 are both configured to use the same USB-LON adapter for LON communications. This creates a resource conflict, typically on the LON1 interface.
Resolution
- Close WorkPlace Tech or reconfigure its communication settings so that LON1 is not used.
- Restart the Niagara R2 station.
- Verify successful adapter initialization by checking the standard output window for:
LON Card Resetting!! LON Card reset complete!! Opened lonworks LON1 >>> Lon Driver opened!
