Application taf.exe

dhyan

Dear All
        I have system with IRB 2400 - Conveyor Tracking and has been working verywell for about one year.
        Someday, when I switched on the controller, there was error "Application taf.exe encountered a serious error and must shut down". 
        And I had no choice, except I must shut down the controller. When I switched on one more time, sometimes It worked (there was no error) but sometimes I encountered the same error.
        May be someone has faced this problem too, please share to me. Thank you very much

Best Regard

Dhyan
