Outputs - National Instruments NI 660 Series User Manual

Outputs

PFI <0..7> are used for DIO only. PFI <32..39> are used for counters and
motion encoders only. You can use PFI <8..31> as either of the three
choices. When used as an output, you can individually configure each PFI
line as a DIO line or a counter line (you need not distinguish between
counter/encoder or DIO applications when you use a PFI line as an input).
Furthermore, the PFI lines associated with gates and sources can be used as
outputs associated with the counter. When used as such, these PFI lines
drive the selected GATE or SOURCE associated with these lines. For
example, if PFI 39 is configured as an output, it will drive the selected
SOURCE of counter 0.
Table 3-3 summarizes what you can drive onto the different PFI lines when
they are used as outputs.
