Product Description

The 1788-CN2DN acts as a gateway that enables a scanner on ControlNet (like a ControlLogix controller) to control and configure devices on a DeviceNet network. This is particularly useful for integrating distributed I/O and motor starters into a centralized ControlNet architecture.

Product Parameters

Product Advantages

• Seamless Integration: Allows legacy DeviceNet systems to be easily upgraded to ControlNet without replacing all field devices.

• Simplified Architecture: Reduces the need for multiple scanners in a chassis by using a single linking device as a bridge.

• Diagnostics: Equipped with comprehensive LED status indicators for quick troubleshooting of network health and power issues.

• Flexibility: Supports both explicit messaging (configuration) and implicit messaging (I/O control) across the bridge.

Key Applications

• Factory Automation: Connecting distributed motor control centers (MCCs) on DeviceNet to a central PLC on ControlNet.

• Process Control: Linking specialized sensors and actuators in harsh environments to high-speed backbone networks.

• Network Extension: Expanding the reach of a ControlNet system to include low-level bit-level devices found on DeviceNet.

Precautions & Installation

Warning: Ensure that the DeviceNet power supply is properly sized. The 1788-CN2DN draws power directly from the DeviceNet network for its communication circuitry.

1. Termination: Ensure both ends of the DeviceNet and ControlNet segments are properly terminated with the correct resistors (121 ohms for DeviceNet) to prevent signal reflection.

2. Addressing: Each linking device must have a unique node address on both networks. Use the hardware switches or software tools (RSNetWorx) to set these correctly.

3. Firmware Compatibility: Verify that your RSLogix/Studio 5000 version supports the specific firmware revision of your 1788-CN2DN module.

4. Grounding: Ensure the DIN rail or mounting panel is properly grounded to minimize electrical noise interference.
