Issue
- Multiple LNS databases under i.Lons or Loytec L-IPs which use the same ethernet network and the same domain ID can cause communication failures.
- Routers stop communicating in random order until some user intervention is taken.
Environment
- LNS
- LonMaker, NL220
Cause
It seems that packets intended for the Operator Unit/Host PC (or from it to other routers) will be received by the other routers and passed down to their Lon networks. This may cause unexpected or duplicated messages to be generated and put back on the ethernet to be received by who knows which device.
Resolution
- Configure all of the networks under multiple i.Lons or L-IPs as a single LNS database
- If that is not an option, ensure that each LNS network has a unique domain ID.
