When using the BACnet driver you can create multiple tuning policies and assign specific tuning policies to BACnet proxy points as needed based on the Bacnet Comm > Network port used (Ip Port, Ethernet Port, Mstp Port). The BACnet driver also supports virtual components that do not exist in the station. It is possible to assign the BACnet virtual components to the different tuning policies, where it requires encoding of the tuning policy as a parameter at the end of the ord in the widget binding (in the Px view). For example, ord;policy=tuningPolicyName. This is an actual ord in a widget binding: Station:|slot:/Drivers/BacnetNetwork/AHU_24/virtual|virtual:/analogValue_184/presentValue;policy=myVirtualPolicy.

Each BACnet network port has its own PollService, including three poll rates (Fast, Normal, and Slow). This varies from other driver networks that use a single PollService.
