Disconnect Channels (Disconnect Channels (Single)) (G Dataflow)

Last Modified: March 3, 2017

Breaks the path between two channels created with the niSwitch Connect Channels node or the niSwitch Set Path node. If no connection exists between the channels, NI-SWITCH returns an error.

session in

Control that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node.

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

channel 1

One of the channel names of the path to break. Pass the other channel names for the switch module.

Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp.

datatype_icon

channel 2

One of the channel names of the path to break. Pass the other channel name as channel 1.

Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp.

datatype_icon

session out

Indicator that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node and used for all subsequent NI-SWITCH calls.

error out

Error information.

The node produces this output according to standard error behavior.
