External Control node stays yellow in PolyScope X (ROS2 connected, RViz working)

Technical Questions

Hi everyone,

I’m trying to use External Control with a UR7e on PolyScope X, but I’m stuck with the node always staying yellow and cannot press “Play”.

Here is my setup:

  • Robot: UR7e

  • PolyScope X

  • External Control URCap installed（1.1.0）

  • ROS2 driver running on my PC

What I have confirmed:

  • Robot and PC can ping each other

  • ROS2 driver is running

  • Port 50002 is listening (0.0.0.0:50002)

  • RViz can visualize the robot and follows real robot motion

  • External Control IP is set to my PC IP (192.168.56.1:50002)

Issue:

  • External Control node stays yellow

  • “Play” button is disabled

Has anyone encountered this issue with PolyScope X?
Could this be a URCap compatibility problem?

Thanks!

Hi, did you try pressing the “Update program” button? That’s what makes the program node fetch the Script code from the ROS machine. After that, the node should become valid and you should be able to play your program.
