Error - How to Resolve the RTDE Error Message When Using Copilot

Disable a specific Copilot function to fix RTDE errors caused by Ethernet/IP incompatibility

Context
When using Robotiq Copilot on Universal Robots, users may sometimes encounter an “RTDE Error Message” during operation. This issue often results from a conflict between Copilot and an active Ethernet/IP connection. This article explains how to resolve the issue using a setting available in Copilot’s URCap.

Information

  • The RTDE (Real-Time Data Exchange) error usually occurs when Ethernet/IP is active while using Copilot.

 

  • A setting was introduced in a previous Copilot URCap release to help mitigate this issue.

Steps to Fix the RTDE Error

  1. Open the Installation tab on the robot.

  2. Navigate to:
    URCaps > Copilot > Configuration

  3. Find the setting:
    “Use Copilot to manage a soft speed transition when resuming from a Safeguard Stop.”

  4. Disable this setting by unchecking the box.

Conclusion
Disabling the soft speed transition setting in Copilot helps avoid RTDE errors caused by Ethernet/IP conflicts. This fix is effective in most cases where the error appears during robot resume operations.
