Hi,

I have found this link: [Remote Control Via TCP/IP - 16496](https://www.universal-robots.com/articles/ur/interface-communication/remote-control-via-tcpip/)

Where i can download details of the ‘primary interface’ for version 5.9

Is there an updated document that covers 5.11

There is a link to documentation PDF on the bottom of the page.  
There were no changes to the primary interface between 5.10 and 5.12
