Interrupt with digital input

Hello,

I am relative new to LabWindows.

I have a program that starts when I press a button. The program controls a motor. Now I press a button on the motor and the program should stop (Safty Stop). The button is connected to an digital input on my card (PCI Express 6343). Now I have the question how I can program the interrupt? I do not know how to do it in CVI (control the digital input everytime the program runs).

I hope someone can help me.

Best regards
