BK2010  | Lightbus Bus Coupler

The BK2000 and BK2010 bus couplers connect the TRS-Lightbus system to the electronic terminal blocks, which can be expanded in modular fashion. One unit consists of one bus coupler, any number of up to 64 terminals and one end terminal. The BK2010 economy variant permits particularly economical creation of peripheral interfacing connections. Up to 64 digital input/output terminals can be connected.

The bus coupler recognises 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 output are clearly separated. The bus coupler automatically begins a further byte if the number of inputs or outputs exceeds 8 bits.

The TRS-Lightbus System is a rapid and safe serial field bus system. The TRS-Lightbus has a ring structure, and up to 254 stations can be operated in a ring. Easy-to-operate standard fiber-optic technology is used for data transmission, which represents excellent value. Thanks to an optimised, efficient telegram structure, the Lightbus achieves a very high user data transmission rate. For the exchange of 32 bit user information 25 m s transmission time is required.
