NX-Series Modular I/O System Connecting to Open Industrial Network Standards Choice of functionality and performance. Integration of Standard I/O and Safety Intuitive and efcient safety programming with PLCopen functions2 Choice of networks The NX-series Communication Coupler Units support global open networks. Select the network that best suits your needs. Lineup of Communication Coupler Units EtherNet/IP Communication Coupler Unit EtherNet/IP uses the Common Industrial NX-EIC202 Protocol (CIP TM) over a standard Ethernet infrastructure. The EtherNet/IP Coupler has a built-in Ethernet switch and two RJ45 ports, to daisy-chain I/O stations without additional hardware. Data exchange over EtherNet/IP uses data links with configurable update cycles, allowing a trade-off between performance and data capacity for each individual link. For details on EtherNet/IP, refer to the EtherNet/IP Catalog (R150). EtherCAT Communication Coupler Unit EtherCAT uses Ethernet as a dedicated NX-ECC202 control network. With a pure Master- Slave architecture and on-the-fly data exchange, it offers unparalleled commu- > P4 nication efficiency.
