Abstract
A building management system includes a communications bus, and devices coupled to the communications bus. The devices are coupled to the communications bus and configured to communicate on the communications bus using a master-slave token passing protocol. A first one of the devices has an active node table stored therein. The active node table includes multiple nodes. Each node represents one of the devices participating in a token passing ring used to exchange information among the devices via the communications bus using the master-slave token passing protocol. The first device is configured to monitor the active node table for new nodes and to identify a new device communicating on the communications bus in response to a determination that the active node table includes a new node.
