Babel Buster BB2-2011 LonWorks  to Modbus RTU Gateway (RS-232)
Babel Buster BB2-2011 is a universal LonWorks to Modbus RTU gateway used to make a single Modbus RTU RS-232 device accessible on a LonWorks network. BB2-2010 can be RTU master or slave, and can be bound to multiple LonWorks devices.

Control Solutions’ Babel Buster® BB2-2011 is a bindable LonWorks® node that functions as a Modbus RTU RS-232 master/slave. A large number of data objects gives you flexibility in mapping Modbus registers to scalar or structured LonWorks network variables. Packed Modbus registers may be parsed to multiple network variables when reading. Multiple data objects may be packed into a single Modbus register when writing. All standard Modbus register types are supported.

Data objects associated with Network Variable Outputs will poll their assigned Modbus register at the interval you specify, and provide the Modbus data to the LonWorks network as an NV update.

Data objects associated with Network Variable Inputs will receive their data from the LonWorks network as an NV update. The received data will be written to the assigned Modbus registers periodically or upon NV update (user selected).

The BB2-2011 is most often used as a Modbus master, but it can operate as a slave. This makes it possible to put LonWorks devices on a Modbus network (but does still require binding and network commissioning with LonMaker or equivalent).

The Babel Buster BB2-2011 is the upgraded replacement for the legacy Babel Buster 232. The BB2-2011 provides four times the network variable capacity, faster processing speed, and requires no installation credits for installation in an LNS based network.
