Issue with trcv_c in dashboard server

Technical Questions Robot Communication

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. :slight_smile:
