Function Features

Data collection and transfer: Allen Bradley 1756-DNB acts as a bridge communication between DeviceNet and the ControlLogix system. Collecting data from DeviceNet module and delivering it to the controller.

Flexible communication modes: It uses strobe, polling, change of state, and cyclic messages to efficiently retrieve data from and supply data to every device. Allen Bradley 1756-DNB sends collected data to the controller as input data and from the controller to individual devices as output. Diagnostic and monitoring capabilities：Allen Bradley 1756-DNB has easy-access diagnostic outputs, diagnostic table inputs, and outputs that allow users to find out the operational status of devices connected to the DeviceNet network. Quickly diagnose problems or failure states in the system and follow through with corrective actions.

Configuration and programming：Allen Bradley 1756-DNB can download configuration data into DeviceNet devices, enabling users to customize how connected devices will operate and which settings will govern them. The module integrates with Logix 5550 controller and other Allen Bradley ControlLogix components. It works with RSNetWorks for easier configuration and put onsite use within an existing industrial automaton infrastructure. Allen Bradley 1756-DNB supports communication with a wide array of DeviceNet devices for interfacing between differing sensors, actuators, and industrial equipment, and hence is largely being used over a range of broad industrial applications.

Advanced Diagnostic and Troubleshooting: Detailed diagnostic information provided by it aids in quick localization of problems in the DeviceNet network or a connected device. This considerably reduces downtime and maintenance costs and provides for efficient troubleshooting and repair.
