Unable to complete the External Control program node on the teach pendant.

[urfeex]

Hello,

I’m trying to use the URCaps external-control to operate a UR7e from an application developed in RoboDK. The Polyscope X version running on the robot is 10.10.0.

The issue is that after I insert the external-control function into the program on the robot pendant, the node remains highlighted in yellow and I cannot start the program (the Play button is disabled).

I have already configured the IP address and port correctly, and even after refreshing/updating the node, it stays yellow. Because of this, I’m unable to run the program and establish the connection with RoboDK.

Could you please advise on how to resolve this issue? Any guidance would be greatly appreciated.

@Automaverso I moved your comment to its own issue, since it was not really related to the one you posted it in.

In order to complete the yellow program node, there has to be a program running at the configured PC on the configured port, in your case 192.168.1.100 in port 50002. That could for example be the ROS driver. Below is a short screencast that shows the behavior as you are probably experiencing it. Then, the reverse_interface_example from the ur_client_library is started on the configured port and the Update program button is pressed again. That fetches the script code from the script sender instance and hereby completes the program node.

If that doesn't work for you, that could for example indicate that

• You don't have an instance of a script sender running on the remote machine
• The script sender on the remote machine doesn't run on port 50002
• There is a firewall on the remote machine preventing the robot to establish a connection to 50002
• The robot cannot reach the machine with the IP address 192.168.1.100
