DAQmx Switch Find Path
Returns information about the path between switch channel 1 and switch channel 2. If the channels are connected, this VI returns the connection path. If the channels are not connected, the VI returns the shortest available connection path if a path is available.

switch channel 1 is the first channel in the connection. A DAQmx switch name constant lists all switch channels available on devices installed in the system. | ||||||||||||
|
switch channel 2 is the second channel in the connection. A DAQmx switch name constant lists all switch channels available on devices installed in the system. | ||||||||||||

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

path is the existing path or an available path between switch channel 1 and switch channel 2. This path uses the same syntax as a connection or disconnection list, and you can wire it directly to the DAQmx Switch Connect VI or the DAQmx Switch Disconnect VI. | ||||||||||||
 |
path status is the status of the requested path.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
