BK9105 bus coupler makes a comprehensive bus terminal I/O system of more than 200 different signal types fully available to Ethernet/IP users. The coupler is ODVA-certified and follows the producer and consumer model for I/O data. It features twelve different LEDs that offer users diagnostic information without requiring additional tools. The device acts as an Ethernet/IP slave and uses standard RJ45 connectors and auto-negotiates either a 10-Mbit/s or 100-Mbit/s Ethernet connection. It has an integrated dual port Ethernet switch which allows flexible topology configurations, and I/O nodes that can be configured in a line topology.
