Assign Dynamic Channels (G Dataflow)

Version:
Last Modified: September 27, 2017

Configures channels for dynamic acquisition (if session in is an acquisition session) or dynamic generation (if session in is a generation session).

Note  

A channel cannot simultaneously be assigned to static generation and dynamic generation.

session in

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

channel list

The channels reserved for dynamic operation.

Examples of valid syntax for this control are 0:31 or 0-15,16-31 or 0-30,31. The order of these channels specifies the order when using the waveform data type instances of the niHSDIO Read Waveform and niHSDIO Write Named Waveform nodes.

Leave channel list blank to specify all channels. Use none to unassign all channels.

error in

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

datatype_icon

session out

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.

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
