Yes, you can use the PFI lines as both counter I/O and DIO lines simultaneously. There are actually several Knowledge Bases on this subject. Here's a good search on http://www.ni.com/support you might like linked
Keyword Search: (660x 6602) dio.Basically, you end up treating all of the PFI lines as one large 32-bit port. The most important thing to remember is 1) not to use the same PFI line for both counter I/O and DIO at the same time! and 2) Make sure you do all of your DIO configurations before counter configurations else the DIO config will write over your counter PFI assignment
s. Hope this helps!
