Can Connect Channels (G Dataflow)
Verifies that a path can be created between two channels.
If a path is possible in the switch module, the availability of that path is returned given the existing connections. If the path is possible but in use, an Implicit Connection Exists warning is returned.
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.
Default: No error
channel 1
One of the channel names of the desired path. Pass the other channel name as channel 2.
Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp.
channel 2
One of the channel names of the desired path. Pass the other channel name as channel 1.
Examples of valid channel names are ch0, com0, ab0, r1, c2, and cjtemp.
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.

path capability
Value that indicates whether a path is valid.
| Name | Description |
|---|---|
| Path Available |
The path is possible and available. |
| Path Exists |
The path is possible, but already exists. |
| Path Unsupported |
The path is not possible in the specified switch module and topology. |
| Resource In Use |
The path is possible, but elements of the path are in use by another existing path. You must destroy the other path before creating this one. |
| Source Conflict |
The path is possible, but connecting the channels will connect two sources. |
| Channel Not Available |
The channel 1 and channel 2 inputs are configuration channels and are thus unavailable for external connections. |
