Hello Community  
I am new to UR an I am going to utilize RTDE Communication protocol for a project , I pull the python project from [GitHub - UniversalRobots/RTDE\_Python\_Client\_Library: RTDE client library and examples](https://github.com/UniversalRobots/RTDE_Python_Client_Library) and follow great tutorials on youtube by simpleStudent [https://www.youtube.com/watch?v=N2nh3iG7kvo](https://www.youtube.com/watch?v=N2nh3iG7kvo) . The question I have faced is the rtde\_control\_loop.urp which I should have it in teach pendant , due to the fact that I have PolyScopeX on control Box ,so .urp version is not recognizable . Is there any way to convert .urp to .urpx for this case?

I think there is currently no direct conversion from .upr to .urpx supported. I think you can do it indirectly by opening the rtde\_control\_loop.urp program in URsim, seeing what the commands are and rewriting the program in polyscopeX

Currently, there is no official tool to directly convert urp-files to .urpx files. As far as I understand it UR rebuilt the whole way the robot-programm is built on maschine level. Hence it is also not possible to convert URcaps.

Beside the manual recration already meantioned you could try following:  
Each `.urp` program generates a corresponding `.script` file. You can extract the `.script` file from the old controller or USB. As far as I remember there is also a tutorial-section targeting that. Then use a use a Script node in PolyScopeX to load and execute the script file.

word of caution: some variables or functions may need adjustment due to differences in environment and syntax of PolyScopeX
