MicroLogix controllers and other DF1 full duplex devices The Ethernet Network Interface ENI allows you to easily connect a MicroLogix onto new or existing Ethernet networks and upload download programs communicate between controllers and generate e mail 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 allows you to connect non Ethernet Allen Bradley programmable controllers to Ethernet networks The ENI uses EtherNet IP services to allow these controllers to intercommunicate via their native PCCC messaging The ENI allows a non Ethernet controller to initiate a message to another device over Ethernet The message can be sent to its application master or to a peer device These communications are also referred to as report on exception messaging When the ENI is connected to a programmable controller the controller can be used for data acquisition or Supervisory Control and Data Acquisition SCADA functions This SCADA ability allows the controller to function as a smart RTU over Ethernet Publication 1761 UMO06B EN P August 2002 1 2 Product Overview The ENI also supports an SMTP mail service that allows an existing controller to send e mail
