EtherNet/IP Connectivity The 1761-NET-ENI and 1761-NET-ENIW provide EtherNet/IP
connectivity for all MicroLogix controllers, CompactLogix controllers,
and other DF1 full-duplex devices. The Ethernet Network Interface,
ENI or ENIW, allows you to easily connect non-Ethernet controllers
onto new or existing Ethernet networks and upload/download
programs, communicate between controllers, and generate email
messages via SMTP (simple mail transport protocol).
EtherNet/IP is an industry standard open protocol which provides
inter-device compatibility. You can exchange information with other
Allen-Bradley Ethernet controllers (SLC, PLC, and ControlLogix) in a
peer-to-peer relationship, so you do not need any master-type device.
The ENI and ENIW also support an SMTP mail service that allows an
existing controller to send email messages to any destination
connected to the network. The email can be used to initiate the
transmission of data or status information.
