The EtherNet/IP Client/Server Network Interface Module allows SLC processors to interface with EtherNet/IP protocol (Explicit Messaging) compatible devices and hosts. The SLC 5/05 with the MVI46-DFNT module provides a second EtherNet/IP port to a separate subnet for communicating with a HMI or SCADA host. For other SLC processors the module provides a serial pass-thru channel 0 service for remote Ethernet programming and troubleshooting.
