Constructing socket message from PLC to UR5e


i want to establish a socket communication between a PLC and UR5e, the goal here is to send datas (commands ) from PLC to UR5e, my question here is : what kind of message (Protocol ) expect the Robot, or how should the data from the PLC be built ?
for example in Port 29999 we can send commads like Play, Stop with the Sockettest 3.0, are this commads just ASCII coded , Strings or have another structure ?

Thank you

In case of port 29999 it’s just ascii string with ‘\n’ termination. I recommend you searching for “dashboard server” on forum, and support site.
For other interfaces it’s not as straight forward, so you need to get deeper in documentation.

thank you for your replay
