Can any one help me on this socket communication?  
now I have programmed the movement in UR Polyscope, as next step I want to connect all movement together with Visual code in Python (main program); does any one know how to call these .urp program via socket communication?

Thank you in advance.

Hi,  
Why not use a socket and connect to the universal dashboard on port 29999.  
Then call “load \<yourprogram.urp\>”

Also in your program : where is s.bind ?

```auto
You should something like : 
s.bind((HOST1, PORT1))

hi, thanks a lot, this problem well solved.  
the correct one is : s.send((“load program.urp”+“\n”).encode())
