Information About 1761-NET-DNI

The 1761-NET-DNI DeviceNet Unit by Allen-Bradley is a DeviceNet interface that provides peer-to-peer messaging communication. The DeviceNet 1761-NET-DNI interface is a standalone, DIN-rail or panel mounted, intelligent DeviceNet-to-DF1 protocol-conversion device that allows existing DF1 devices to communicate on a DeviceNet network. This DF1 device receives enclosed DF1 messages from a DeviceNet unit and it also exchanges I/O data with the master device. The 1761-NET-DNI has various features. The most crucial of these are the explicit messaging features and the ability to program other machines through a DeviceNet I/O. For safety precautions, this unit needs to be mounted in an enclosure when operated. It can be mounted in a horizontal or a vertical position. The 1761-NET-DNI is flexible and needs no spacing except as necessary for DIN rail latch movement. This unit is equipped with a single DeviceNet connection point with a single RS-232 port. Both these ports are isolated from each other. The 1761-NET-DNI requires a power source of 24V DC to operate and it needs an operating temperature of 32-140 degrees Fahrenheit to function effectively. The main functions of the 1761-NET-DNI are to collect and receive the data from the connected DF1 device and then to send it to the Master unit connected to the DeviceNet network. The 1761-NET-DNI monitors the output data acquired from the master connection and it allows sending and receiving messages across the DeviceNet network.

The Allen-Bradley 1761-NET-DNI is a DeviceNet interface. This device is a stand-alone component that functions as a protocol converter. It allows DF1 enabled devices to exchange data and communicate with devices residing on a DeviceNet network. This module uses a DIN rail or panel mounting and is compatible for use with MicroLogix controllers, PLC5, SLC 5/03, and higher processors as well as Human Machine Interfaces (HMI).

The 1761-NET-DNI comes with two (2) communication interfaces, with Port 1 supporting DeviceNet network and comes with a field replaceable 3-wire terminal block. This terminal block has a replacement part-number of 1761-RPL-0000. Port 2 of this device is an 8-Pin mini-DIN circular RS-232 interface that supports DF1 full protocol.

The 1761-NET-DNI is designed to operate in peer-to-peer and DeviceNet slave mode. Specifically, it supports being configured to perform peer-to-peer messaging and DeviceNet Master/Slave I/O.

When installed in Class I, Division 2 Hazardous Environment, applicable communication cables for this communication interface are 1761-CBL-PM02 Series C (or later); 1761-CBL-HM02 Series C (or later); 1761-CBL-AM00 Series C (or later); 1761-CBL-AP00 Series C (or later); and the 1761-RPL-00 DeviceNet Connector. It supports horizontal and vertical mounting and operates when wired to an 11-25 Volt DC power supply source. It has a current draw of 250 milliamperes @ 24 Volts DC; 350 milliamperes @ 11 Volts DC and maximum inrush of 400 milliamperes for 30 milliseconds @ 24 Volts DC. It has an internal isolation rated at 500 Volts DC and operates at an ambient temperature of 0 to 60 degrees Celsius (32 to 131 degrees Fahrenheit) while the device’s storage temperature is -40° C…+85° C (-40° F…+175° F).
