Issue
What is the Network ID-UDP Setting required for and does this need to be changed when commissioning a new BACnet Continuum controller?
Product Line
Andover Continuum
Environment
- bCX4040
- bCX4000
Cause
Require information on the Continuum BACnet Network setting (physical layer).
Resolution
Each network segment in a BACnet network is assigned a unique integer as an identifier for ease of routing packets between these networks. For more information see Effect on a BACnet network if the Network Id - UDP setting in bCX40x0 have been set to different val...
BACnet Network ID-UDP Setting
This defines the ID number of the BACnet/IP network on which this controller resides. When creating a Continuum BACnet controller the default UDP Net ID is set to 1. This setting would need to be the same for all BACnet controllers that want to communicate with each other across the network.
Why would you want to change it?
You may have a site for example that already has a BACnet network running on the ethernet and not want to communicate on the same BACnet UDP Net Id as their BACnet devices do. In this case you could change the UDP Net Id for your BACnet communications but it needs to be the same for all of your BACnet devices since the routing tables in the controllers would need to know which UDP Net Id to route to. If you changed the UDP Net Id to 2 then all controllers would need to be set to 2 to make sure they were able to communicate efficiently with each other.
