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.

• PFI for Isolated Devices—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
