A building automation system (BAS) comprising a plurality of end devices, at least one communication network, and a server engine comprising a communication state manager for actively managing the state of various devices in building automation system and an associated reconnect manager to reestablish communication with off-line devices. The communication manager and the reconnect manager coordinate the interaction between the server engine and the devices in order to minimizing the load on the communication network, while also working to establish the working state of any of the end devices and to transition off-line to an on-line state.

Active device management for use in a building automation system

A building automation system (BAS) network manager supporting a plurality of device protocols coupled to at least one communication network, and a plurality of logical connections to individual BAS networks to multiple end devices of a BAS. The BAS network manager can communicate with each of the end devices regardless of the protocol or protocol version of the BAS network by implementing a protocol stack above the link layer for each protocol or protocol version, providing an integrated multi-BAS network interface, and maintaining a device identifier for each BAS network the network manager is coupled to in the protocol stack.
