Hello, I’m communicating a UR3 with a PLC using a dashboard server (port 29999). The sending part of commands with tsend works perfectly, but when it comes to receiving the responses to those commands, I only get “Connected. Universal Robots Dashboard Server$L” in the char array. It doesn’t matter how many commands I execute, the trcv never updates, and it always stays in “busy”.
Does anyone know exactly what’s happening and how I can fix it?
Thanks for reading, greetings from Spain.

Kadams has uploaded some good screenshots.
You have to stop the TRCV and start it again, when you start the TSEND.
