SCTL & NI9401: Basic Questions

Hy,

i got some questions about the execution time of the SCTL with I/O of the 9401 Module.

E.g.: I got an quad encoder, to read in the signals i use a sctl with a 40Mhz clock.

The sctl will execute the code inside within one tick (25ns), but now i saw in the spec. sheet that the I/O Input of the 9401 Module got an latency of 100ns.

What does that mean regarding to my sctl and the input states of my modul?

Thanks a lot.

Greetings,

Ben
