Control Solutions’ Babel Buster BB2-2011-NB is a Modbus master/slave used to connect LonWorks devices to a Modbus network without binding or LonWorks network management outside of the gateway’s own capabilities. A large number of data objects gives you flexibility in mapping Modbus registers to scalar or structured LonWorks network variables. Multiple registers may be mapped a single structured LonWorks network variable. Modbus holding registers, input registers, discrete inputs, and coils are supported.

The LonWorks network variables will be polled periodically to read LonWorks data, or updated upon change in value (or periodically if chosen) to write LonWorks data. Data read from LonWorks will be placed into Modbus registers. Data written to Modbus registers will be written to LonWorks network variables.

The BB2-2011-NB is most often used as a Modbus slave, providing LonWorks data to a Modbus master such as a control system PLC. The BB2-2011-NB can also be configured as a Modbus master, automatically reading and writing Modbus registers in other Modbus slaves to share LonWorks data.

The BB2-2011-NB provides poll 400 data objects which may be accessed as any of the standard Modbus register types. These 400 registers may be mapped to as many as 300 LonWorks network variables, with multiple Modbus registers often mapped to a single LonWorks network variable.
