Hello oferA,

Your PCI-6601 does not support change detection. The exercise that you are trying to run does not support that card. If you are using the NI Example Finder you will noticed in the lower right hand corner there is a window that is labelled "Requirements" and that tells you which devices are able to run the example.

Refer to the following link for devices that support change detection:

Which NI DIO Devices Support Change Detection?
