BACnet Router Addressing¶
The underlying library that Volttron uses for BACnet supports IP to MS/TP routers. Devices behind the router use a Remote Station address in the form:
<network> is the configured network ID of the router and
<address> is the address of the device behind the
For example to access the device at
<address> 12 for a router configured for
<network> 1002 can be accessed with
<network> must be number from 0 to 65534 and
<address> must be a number from 0 to 255.
This type of address can be used anywhere an address is required in configuration of the Volttron BACnet driver.
VOLTTRON uses a UDP broadcast mechanism to establish the route to the device. If the route cannot be established it will fall back to a UDP broadcast for all communication with the device. If the IP network where the router is connected blocks UDP broadcast traffic then these addresses will not work.
