Hi its me again

Early in the morning we have started our robot but he only gave us the following error:

Application Taf.exe encountered a serious error and must shut down.

What causes this error and how can we fix it?

Thanks for the help 🙂

Many greetings

Tami

Hi Tami,  
It seems as some application on the FlexPendant doesn’t works correct. Restore the system from backup, hopefully will that solve the problem.

Hey,

it was only a loose connection in the cable 🙂

We changed it and now it works.
