The BC9120 Bus Terminal Controller is a Bus Coupler with integrated PLC functionality and has a bus interface for Ethernet. It is an intelligent slave and can be used as decentralized intelligence in the Ethernet system. In conjunction with the K-bus extension, the Economy plus controller enables connection of up to 255 Bus Terminals to a controller.
The BK1120 EtherCAT Coupler is the link between the EtherCAT protocol at fieldbus level and the Bus Terminals. The coupler converts the passing telegrams from Ethernet 100BASE-TX to the internal, fieldbus-independent terminal bus.
The Economy plus version extends the existing PROFIBUS Bus Coupler series BK3xx0. The K-bus extension technology allows the connection of up to 255 spatially distributed Bus Terminals to one Bus Coupler.
