Programmable Function
Interfaces (PFI)
Refer to one of the following sections, depending on your device:
•
PFI for Non-Isolated Devices
—NI 6124 devices have 16 PFI pins in
addition to eight lines of bidirectional DIO signals.
•
—NI 6154 devices have 10 equivalent
directional PFI pins that can be independently configured as an input
or output.
PFI for Non-Isolated Devices
(NI 6124 Only)
Non-isolated S Series devices have 16 Programmable
Function Interface (PFI) signals. In addition, these devices have eight lines
of bidirectional DIO signals.
Each PFI can be individually configured as the following:
•
A static digital input
•
A static digital output
•
A timing input signal for AI, AO, DI, DO, or counter/timer functions
•
A timing output signal from AI, AO, DI, DO, or counter/timer
functions
