Compact series bus couplers from Beckhoff have been supplemented with the new BK9055 for EtherNet/IP. The BK9055 couples EtherNet/IP with the modular Beckhoff bus terminal system, which offers over 400 different signal types. The series is characterised by slim housings and cost-optimised design.
The new bus coupler allows the inexpensive connection of the Beckhoff I/O system to EtherNet/IP networks. The BK9055 is software-compatible to the BK9105 EtherNet/IP coupler from Beckhoff, which unlike the compact version, has a second RJ 45 port (2-channel switch). Therefore, the I/O stations can be configured in a line topology, instead of the classic star topology.
For use in industrial Ethernet systems, the compact series are also available for Profinet (BK9053) and Ethernet (BK9050). In addition to Ethernet TCP/IP, the BK9050 also supports Modbus TCP as well as cyclic data exchange in accordance with the EtherCAT Automation Protocol (EAP).
EtherCAT interoperability removes industrial networking barriers
Fieldbus & Industrial Networking
Selecting the right communication technology is one of the most important decisions engineers make, and interoperability helps with that decision. Key development tools and standards ensure interoperability among many EtherCAT devices and manufacturers.

The purpose of this particular article is to try and give those unfortunate enough to have to use SWAG (scientific wild ass guess) tuning a bit of an idea of how to go about it, and even more importantly some understanding of a couple of basic principles.
