Issue
AS-L Loses LON Configuration
Environment
StruxureWare Building Operation LON environment
Cause
After commissioning the local node with a LNS tool and if one switches off the power supply of the AS-L, the local node loses the LON configuration and it return in factory configuration 'Domain 18 Subnet 1 node 254'. Now you can just change the domain.
Resolution
It seems the local node updates the domain if the domain is updated from LNS. So if you do a Local Node commission than the LNS will not work and if you commission it from LNS local node is not going to update the domain.
This really falls under design issues. A local node is typically only available for LNS network management tools and front ends. It seems it is not the design of the device to be used in another LNS network management tool since StruxureWare Building Operation and the AS-L is a LNS network management tool. Using two different tools complicates systems greatly since there should be only one.
