Description

The Allen-Bradley 1756-CN2R/B is a ControlNet Communication Module designed for use with Rockwell Automation’s ControlLogix controllers. It provides a bridge between the ControlLogix controller’s backplane and ControlNet networks, enabling communication with ControlNet devices and other systems.

Key Features:

  • ControlNet Connectivity: Connects the ControlLogix controller to a ControlNet network, allowing communication with ControlNet devices and other systems that support the ControlNet protocol.
  • Dual-Port Design: Features two ControlNet BNC connectors, enabling redundant communication paths and enhancing network reliability.
  • Hot-Swappable: The module can be replaced while the ControlLogix controller is still running, minimizing downtime for maintenance or configuration changes.
  • Remote I/O Support: Supports remote I/O modules connected to the ControlNet network, expanding the controller’s I/O capabilities.
  • Class 0, Class 1, and Class 3 Messaging: Supports various ControlNet messaging classes for different communication requirements.

Applications:

The 1756-CN2R/B is commonly used in various industrial automation applications that require ControlNet connectivity, including:

  • Manufacturing Assembly Lines: Connecting ControlLogix controllers to ControlNet-based sensors, actuators, and other devices on the assembly line.
  • Process Control Systems: Enabling communication between ControlLogix controllers and ControlNet-based field devices in process control applications.
  • Building Automation Systems: Integrating ControlLogix controllers into ControlNet-based building automation systems for HVAC, lighting, and security control.
  • Transportation Systems: Connecting ControlLogix controllers to ControlNet-based devices in transportation systems like conveyor belts and automated warehouses.
  • Oil and Gas Industry: Enabling communication between ControlLogix controllers and ControlNet-based devices in oil and gas production, refining, and distribution systems.

Additional Notes:

  • The specific configuration and network settings for the 1756-CN2R/B depend on the ControlLogix controller model and the ControlNet network topology. Refer to the Rockwell Automation documentation for detailed configuration instructions.
