Information About 1761-NET-ENI

The Allen-Bradley 1761-NET-ENI is an Ethernet/IP communication interface. It provides connectivity for CompactLogix, MicroLogix, and SLC 500 devices, as well as other DF1 full-duplex devices to Ethernet network. The 1761-NET-ENI has a 100 Base-T Port embedded with LEDs which allow for reliable connection to an Ethernet network. It is provided with visual indicator LEDs that provide easy-to-view links and transmit/receive statuses. It is equipped with an RS-232 port which provides isolation and will auto-baud on power-up for detecting the communications of the port setting of the controller attached to it. The 1761-NET-ENI is provided with the ability to force Ethernet to 11 Mbps or 100 Mbps and half-duplex or full-duplex where the default us auto negotiable. Configuration over Ethernet can be done with a configuration security mask provision.

The 1761-NET-ENI’s most vital feature is the diagnostic page which displays the important module information and all the Ethernet connections in use. One of the best things about the 1761-NET-ENI communication interface is that it is efficient and delivers exceptional output with less power consumption. The maximum operating temperature for the 1761-NET-ENI is 0 to 70 degrees Celsius and the maximum storage temperature is -45 to 85 degrees Celsius. The most commonly used standards are IEC801-2, 3, 4, 5, and 6. Its operating humidity is 5-95% non-condensing. The 1761-NET-ENI’s regulation, approvals, and certifications include the UL, C-UL, CE, and Class 1, Division 2 certifications; this module provides Ethernet/IP connectivity to all DF1 full-duplex devices including all MicroLogix and CompactLogix controllers. This Ethernet Interface permits uploading or downloading of programs, communicate between controllers and generate emails while connected to non-Ethernet controllers.

The 1761-NET-ENI is an Allen-Bradley Advanced Interface Converter (AIC) which enables DF1 capable devices such as MicroLogix, CompactLogix, SLC 500, PLC5 and 3rd party devices to connect to an EtherNet/IP network. This converter basically allows a point-to-point device to connect to a multi-node communication network.

The 1761-NET-AIC is provided with an isolated 8-Pin Mini DIN RS232 port that supports full-duplex DF1 protocol. Through this port, the DF1 capable device connects while the ethernet network is interfaced through the provided RJ45 port. The interface converter is mounted separately from the PLC, thus, not occupying a slot of a modular PLC or an expansion module. It is energized with an input supply voltage of 24VDC.

The 1761-NET-AIC is ideal for multiplexing the embedded serial port of the connected device and allows enables an old controller to connect to a modern ethernet network without adding a ethernet communication module or replacing the entire controller. This saves engineering development manhours as well as reduces shutdown caused by commissioning when the connected device is replaced.

This interface converter supports 10/100 Mbps ethernet connection with auto-negotiation function at a maximum distance of 100 meters. If more distance is required, the ethernet cable may be converted to fiber optic to cover longer distances. This interface converter is also provided with Simple Mail Transport Protocol (SMTP) service. This is the service that enables sending email messages to destination in any point of the connected network.

Series A and B interface converters support Ethernet 10-Base-T. 1761-NET-AIC Series C and D supports 10/100 Base-T transmission speed. The converter device compatibility includes all MicroLogix, SLC, PLC-5, CompactLogix, FlexLogix, ControlLogix and any device that is capable of DF1 Full-Duplex on an RS-232 port.
