Issue
All of the nodes are yellow and when they are clicked on the error below is displayed even though the database is attached to the network (OnNet), the network interface is on the correct channel, and the network interface passed all applicable tests.
Environment
- NL220
Cause
When the nodes appear yellow, this means that the LNS database has been corrupted.
Resolution
It can be attempted to repair the database using the Echelon LNS Database Validator. Follow these steps.
- If NL220 is still running, shut it down.
-
Go to the Start menu > All Programs > Echelon LNS Utilities > LNS Database Validator.
- Select the corrupt database in the "Network to Validate" drop down box.
- Check the box next to Repair Database.
- Now click on the button called Validate.
If these steps do not repair the database, send the LNS database backup to Echelon support to see if they can correct the problem.
