Read Static PFI (U32) (G Dataflow)

Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Handle that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.

The returned bit value of data read from PFI channels configured for static acquisition.

The least significant bit of read data corresponds to the lowest physical channel number. For example, bit 0 corresponds to PFI0, and bit 31 corresponds to PFI31, if that channel exists on the hardware.

If read data returns a value of 0x000F, channels PFI0 to PFI3 are logic one and the remaining channels are logic zero or are not configured for static acquisition.

If read data returns a value of 0xFFF0, channels PFI4 to PFI15 are logic one and the remaining channels are logic zero or are not configured for static acquisition.
