Beckhoff Automation LLC BK9000 | Ethernet TCP/IP Bus Coupler

The BK9000 Compact Bus Coupler with compact housing connects Ethernet with the modular, extendable electronic terminal blocks. One unit consists of one Bus Coupler, any number from 1 to 64 terminals and one end terminal. With the K-bus extension, up to 255 Bus Terminals can be connected. The Bus Coupler recognizes the terminals to which they are connected, and performs the assignment of the inputs and outputs to the words of the process image automatically. The BK9000 supports 10 Mbit/s and 100 Mbit/s Ethernet. Connection is through normal RJ45 connectors. The IP address is set on the DIP switch (offset to a freely selectable start address). In networks with DHCP (a service for the allocation of the logical IP address to the physical node address [MAC-ID]) the Bus Coupler obtains its IP address from the DHCP server. The Bus Coupler supports ADS TwinCAT system communication. TwinCAT I/O makes available configuration tools and Windows NT/2000/XP drivers for programs in any desired high-level language (DLLs) and for Visual Basic applications (ActiveX). Applications with OPC interfaces can access ADS (and therefore the BK9000) via an OPC server. In addition to ADS the Bus Coupler supports Open Modbus (Modbus TCP), a simple, widespread master/slave protocol based on TCP/IP.
