Model: 1756-N2

Detailed Explanation of Allen-Bradley 1756-N2


The Allen-Bradley 1756-N2 is a communication bridge module designed to facilitate seamless communication and integration within ControlLogix control systems. It serves as a critical component for connecting ControlLogix controllers with devices and systems operating on different communication protocols or network architectures.

Key Features:

  • Communication Protocol Support:
    • Ethernet/IP: The 1756-N2 supports Ethernet/IP, a widely used industrial protocol that enables real-time communication between devices and systems over Ethernet networks. It allows ControlLogix controllers to exchange data with Ethernet/IP compatible devices such as HMIs, SCADA systems, and other PLCs.
    • ControlNet: This module also supports ControlNet, a deterministic network protocol primarily used for high-speed control and data acquisition in industrial automation. It enables integration with ControlNet devices and networks, extending the reach of ControlLogix systems in larger and complex applications.
    • DeviceNet: DeviceNet support allows the 1756-N2 to interface with devices operating on the DeviceNet protocol, which is commonly used for connecting industrial devices like sensors, actuators, and drives to control systems. It facilitates efficient data exchange and control in distributed automation environments.
  • Bridge Functionality:
    • The 1756-N2 acts as a bridge or gateway between these different communication networks. It translates and routes data packets between ControlLogix controllers and devices connected to Ethernet/IP, ControlNet, or DeviceNet networks.
    • This bridging capability is essential for ensuring interoperability and communication continuity across diverse network infrastructures within industrial automation systems.
  • Configuration and Integration:
    • Configuration of the 1756-N2 module is typically performed using Rockwell Automation’s Studio 5000 software (formerly RSLogix 5000). Engineers and system integrators use this software to define network parameters, set up communication paths, and configure data exchange mechanisms.
    • Integration with ControlLogix systems involves installing the module into the ControlLogix chassis and configuring it to establish communication links with connected devices. This integration process ensures seamless operation and compatibility within the overall control system architecture.
  • Application and Use Cases:
    • The 1756-N2 module finds application in a wide range of industrial automation scenarios where there’s a need to integrate ControlLogix controllers with devices and systems operating on different communication protocols.
    • Common use cases include manufacturing automation, process control, material handling systems, and utility management, where diverse networks and protocols coexist and need to communicate effectively.


  • Enhanced Connectivity: Facilitates seamless connectivity between ControlLogix controllers and devices on Ethernet/IP, ControlNet, and DeviceNet networks, enhancing overall system flexibility and functionality.
  • Improved Efficiency: Optimizes data exchange processes, ensuring timely and accurate transmission of control data and status information across integrated networks.
  • Scalability and Adaptability: Supports scalable deployment options and enables easy expansion of control systems to accommodate evolving operational requirements and network expansions.


The Allen-Bradley 1756-N2 communication bridge module plays a crucial role in enabling interoperability and communication flexibility within ControlLogix control systems.
