RTDE protective Stop

Hello everyone,

I’m currently working on an UR-5 robot.
I have connected the robot to a screen via a display port in order to turn it into a Teach (I consider this to be the robot’s monitor).

The robot is also connected to my pc via an Ethernet cable.

I use my pc to make the robot run a program (written in python). This program is sent via the Windows command prompt.

However, I regularly get a message on the robot’s monitor:
“RTDE modbus protective stop”.

I’ve checked the code and the connections, and I can’t see where the problem lies.

If you have a clue or a solution, I’d love to hear from you.
