We experience occasionally that the UR has the “NO CONTROLLER” error when pressing play on a program in the teach pendant. The program contains an event from our own URCap. This has happened on two different robots around twice a month, when they are used every day for development.
I can provide a support file if it can help.
Steps to reproduce:
This is an occasional bug that we cannot reproduce on purpose.
When pressing the play button, that the program starts as usual.
When pressing the play button, the UR goes to “NO CONTROLLER” state without any visible error message.
Robot Serial Number:
Polyscove version 18.104.22.1680533
UR robot: UR16e
