Beckhoff Introduces New Ethernet TCP/IP I/O Bus Coupler and Controller
Integrated switch reduces wiring effort, BC9100 model features programmable PLCMINNEAPOLIS, June 30, 2005 The new Ethernet TCP/IP BC9100 Bus Terminal Controller and BK9100 Bus Coupler for the Bus Terminal I/O system add to the already wide range of Ethernet products available from Beckhoff. These two Bus Coupler variants feature an integrated 2-port switch, simplifying the cabling between Ethernet stations and greatly reducing overall wiring effort.The new Ethernet Bus Couplers are based on the BC9000 and BK9000 models, which have been used for years in numerous applications. The BK9100 Bus Coupler connects the Ethernet TCP/IP bus system with over 180 different Beckhoff I/O terminals. The BC9100 controller version adds an IEC 61131-3 programmable PLC and can be used as a low-cost local controller.These new versions also feature an RJ 45 port with integrated 2-channel switch. The I/O stations can be configured with a line topology, instead of the classic star topology via switch or hub. This significantly reduces the wiring effort and the cabling costs in many applications. The maximum distance between two bus stations can be up to 100 m. It is possible to cascade up to 20 BK9100 Bus Couplers or BC9100 Bus Terminal Controllers.Beckhoff Ethernet components speak several "languages." In addition to ADS TwinCAT system communication, the Ethernet devices also support Modbus TCP. With the TwinCAT System Manager as a driver, the BK9100 Bus Coupler can be set up with real-time Ethernet, offering cycle times of up to 1 ms. The Ethernet Couplers support 10 Mbaud and 100 Mbaud Ethernet with automatic transfer rate detection. The IP address can be set via DIP switches, via the associated DHCP server (in networks with DHCP), or via the BootP server available from Beckhoff.Beckhoff Automation provides advanced, open automation products based upon proven technologies so that customers can implement high performance control systems faster and at a lower overall cost than traditional PLC and motion control systems.
