Abstract
A building automation system and method is provided for isolating device communications in a BACnet/IP building automation network. The system may comprise at least one processor in a BACnet device configured via executable instructions included in at least one memory to communicate UDP messages for field devices onto an Ethernet network for receipt by at least one other BACnet device on the Ethernet network. The at least one processor may be configured to receive and store in a memory a configurable local subnet, a BACnet/IP UDP port, and a local UDP port. The at least one processor may also be configured to determine a UDP message that is to be broadcast only on the local subnet. In addition, the at least one processor may be responsive to the determination, to broadcast the UDP message to BACnet devices on the same local subnet using the local UDP port stored in the memory.
