Descripción

The BK1120 Bus Coupler connects EtherCAT with the K-bus components (KLxxxx) from the proven Beckhoff Bus Terminals range. One station consists of a BK1120 Bus Coupler, any number of terminals (up to 64; up to 255 with K-bus extension) and a bus end terminal. The Bus Coupler recognises the connected terminals and automatically allocates them into the EtherCAT process image. The Bus Coupler is connected to the network via the upper Ethernet interface. The lower RJ45 socket may be used to connect further EtherCAT devices in the same strand. In the EtherCAT network, the BK1120 Bus Coupler can be installed anywhere in the Ethernet signal transfer section (100BASE-TX) – except directly at the switch. The coupler BK9000 (for K-bus components) is suitable for installation at the switch. The BK1120 Bus Coupler connects EtherCAT, the real-time Ethernet system, with the modular, extendable electronic terminal blocks. A unit consists of a Bus Coupler, any number (between 1 and 64) of terminals (255 with K-bus extension) and one end terminal.
