BACnet driver

BACnet/IP runs in the commission container (network_mode: host). The bridge exposes commissioning UI and REST routes.

Configuration

• workspace/bacnet/commissioning/commission.env — NIC, BBMD, device filters (OPENFDD_BACNET_SERVER_ENABLED=0 on commission)
• docker/compose.edge.rust.yml — bridge vs commission server flags split (bridge 1, commission 0)
• OPENFDD_BACNET_MODE — live for field buses

Compose split: bridge runs the local diagnostic device (599999). Commission runs field Who-Is — never enable the local BACnet server on the commission container.
