Beckhoff BK2000 / BK 2000

The BK2000 Bus Coupler connects the Lightbus system to the electronic terminal blocks, which can be expanded in a modular fashion. One unit consists of one Bus Coupler, any number of up to 64 terminals, and one end terminal.

The Bus Coupler recognizes the connected terminals and automatically generates the affiliations of the inputs/outputs to the bytes of the process image. The first input/output signal is inserted in the first bit of one byte (LSB), beginning from the left. The Bus Coupler inserts further signals in this byte. Inputs and outputs are clearly separated. The Bus Coupler automatically begins a further byte if the number of inputs or outputs exceeds 8 bits.
