Ethernet Connections
The Ethernet port connects to a controller on an EtherNet/IP network by using
standard Ethernet and network connections. The port also supports application
transfers, and printing.
Ethernet Connector
The Ethernet port has an RJ45, 10/100Base-T connector for network
communication and supports MDI/MDI-X connections.
