1771 SDN PLC Devicenet Scanner Module

The 1771-SDN PLC DeviceNet Scanner Module is a component in the Allen-Bradley PLC (Programmable Logic Controller) system, specifically designed for integrating a PLC with a DeviceNet network. DeviceNet is a digital, multi-drop network that connects and serves as a communication network between industrial control systems and field-level I/O devices. Here’s an overview of the 1771-SDN Scanner Module:

Key Features:

  1. DeviceNet Integration: The primary function of the 1771-SDN is to act as an interface between the PLC and DeviceNet network, allowing the PLC to communicate with and control devices on the DeviceNet network.
  2. I/O Messaging: The module handles I/O messaging and control for devices connected to the DeviceNet network, such as sensors, actuators, motor controllers, and other industrial components.
  3. Data Collection and Monitoring: It facilitates data collection from and monitoring of devices on the DeviceNet network, enabling centralized control and data analysis.
  4. Network Configuration and Diagnostics: The 1771-SDN provides tools for configuring the DeviceNet network, as well as diagnostic capabilities to help identify and troubleshoot network issues.


  1. Manufacturing Automation: Commonly used in automated manufacturing processes for controlling and monitoring various field devices.
  2. Material Handling Systems: Suitable for conveyor systems, sorting machines, and other material handling equipment requiring coordinated control.
  3. Process Control: Utilized in process control environments in industries like chemical, pharmaceutical, and food and beverage.
  4. Machine Control: Often employed in machine control applications where multiple devices need to be networked and controlled efficiently.

Technical Considerations:

  1. Compatibility: The 1771-SDN is designed to work with specific Allen-Bradley PLC models, so ensuring compatibility with your PLC system is crucial.
  2. Installation and Configuration: Proper installation in the PLC chassis and configuration through appropriate software tools is necessary for effective operation.
  3. Firmware Updates: Keeping the module’s firmware updated ensures optimal performance and compatibility with newer devices and technologies.
  4. Network Design: A well-planned DeviceNet network layout is essential for effective communication and to avoid potential data collisions and network bottlenecks.


The 1771-SDN PLC DeviceNet Scanner Module is a critical component for integrating Allen-Bradley PLCs with a DeviceNet network, enabling efficient communication and control of networked field devices. Its role in streamlining operations and enhancing system capabilities makes it a valuable addition to various industrial automation applications. However, proper installation, configuration, and maintenance are key to leveraging its full potential.
