Babel Buster BB2-3060 BACnet MS/TP to Modbus TCP Gateway
Babel Buster BB2-3060 is a BACnet MS/TP to Modbus TCP gateway. The BB2-3060 is a TCP client making Modbus TCP devices accessible on a BACnet network. BB2-3060 can also be a BACnet client making BACnet devices accessible from a Modbus TCP network.

Control Solutions’ Babel Buster® BB2-3060 is a BACnet MS/TP client/server device that functions as a Modbus TCP master/slave. A large number of BACnet objects gives you flexibility in mapping Modbus registers to any combination of BACnet objects. Packed Modbus registers may be parsed to multiple BACnet objects when reading. Multiple BACnet objects may be packed into a single Modbus register when writing. All standard Modbus register types are supported.

Input objects will poll their assigned Modbus register at the interval you specify, and provide the Modbus data as the Present Value when read. Commandable Output objects are used to write Modbus registers, and will update the Modbus device each time BACnet is updated. The BB2-3060 supports up to 300 non-commandable objects, or up to 135 commandable objects, or a mix in between.

Value objects will poll their assigned Modbus register at the interval you specify. The content of the Modbus register will be given as the Present Value of the BACnet object when read. The Modbus register is written each time the BACnet Value object is written. The Value object corresponds to the Modbus Holding register.

The BB2-3060 is most often used as a Modbus master, but it can operate as a slave while MS/TP operates as a client (master). This makes it possible to put MS/TP devices on a Modbus network (but does still require an understanding of BACnet). MS/TP data in remote devices is queried and saved locally. The local data may then be accessed by another Modbus master.
