EtherNet/IP Bus Coupler for Beckhoff I/O system

Open Ethernet technology for fieldbus and industrial networking

Beckhoff maintains a long-standing tradition of open control technology and giving customers the flexibility to choose from all leading Ethernet protocols. The BK9105 Bus Coupler makes the comprehensive Beckhoff Bus Terminal I/O system of over 200 different signal types fully available to EtherNet/IP users.

The BK9105 Bus Coupler is an EtherNet/IP slave and uses standard RJ45 connectors and auto-negotiates either a 10 Mbit/s or 100 Mbit/s Ethernet connection. The coupler has an integrated dual port Ethernet switch which allows for extremely flexible topology configurations. I/O nodes can be configured in a line topology as an alternative to the traditional star topology. In many applications the line topology and use of RJ45 connectors significantly reduces the required wiring effort and cabling cost. The BK9105 is ODVA certified and follows the producer and consumer model for I/O data.

The BK9105 can be given an IP address via several different mechanisms. For example, the BK9105 can be auto-addressed via a BootP or DHCP server, BK9105 and the server assigned IP address can be stored permanently. The BK9105 can also be addressed manually or via DIP switches.

Twelve different LEDs offer users a wealth of diagnostic information without additional tools, including: simple voltage displays, Ethernet port status and a wide range of information regarding established connections or EtherNet/IP communication status.

Open Ethernet solution supports numerous protocols

In addition to the ultra high-speed, deterministic EtherCAT system, Beckhoff supports almost every major "Ethernet fieldbus", complementing traditional fieldbus systems. The Beckhoff Bus Terminal system supports 17 bus systems and 7 different Ethernet protocols:
– BK9000, BK9100: ModbusTCP, ADS/TCP, ADS/UDP, real-time
Ethernet
– BK9103: PROFINET (in preparation)
– BK9105: EtherNet/IP
– BK1120: EtherCAT

A separate Beckhoff I/O Bus Terminal system is also available for EtherCAT. In contrast to Bus Terminals, where the fieldbus signal is contained within the Bus Coupler and translated into a “fieldbus-neutral” terminal bus, the EtherCAT protocol remains fully intact as it passes through each individual I/O terminal. EtherCAT can replace the Ethernet star topology with a simple line structure containing any number of nodes or with flexible tree topologies.
