Modbus to BACnet IP Gateway BB3-7101

Babel Buster BB3-7101 Modbus to BACnet IP Gateway

The Babel Buster BB3-7101 Modbus to BACnet IP gateway allows Modbus devices to communicate with BACnet IP devices. BACnet objects may be read as Modbus registers, and Modbus registers may be read as BACnet objects. The Modbus to BACnet IP gateway acts as a translator between the two protocols.

The Modbus to BACnet IP gateway may be both Modbus TCP client and server at the same time, and can be configured to also be a Modbus RTU master or slave that runs independently of Modbus TCP. The BB3-7101 will continuously poll Modbus registers in TCP or RTU devices and make that data accessible as BACnet objects. Configured to go the other way, the BB3-7101 will continuously poll objects in other BACnet devices and make that data accessible as Modbus registers for other Modbus masters polling the BB3-7101.

Babel Buster BB2-7030 BACnet Router can also operate as a BACnet gateway, reading and writing other BACnet devices and retaining a copy of object values in its own set of BACnet objects. The BB2-7030 also provides a Modbus TCP client and server, or SNMP client and server, for additional gateway flexibility.
