Beckhoff BK9000 – Overview
The Beckhoff BK9000 is a compact bus coupler that connects a modular terminal block system to a standard Ethernet TCP/IP network. It supports data rates of 10 Mbit/s and 100 Mbit/s, and handles automatic process-image mapping for up to 64 bus terminals, expandable to 255 using the K-bus extension.
This module simplifies the integration of I/O modules into Ethernet-based automation systems.
