Returns a string that identifies the explicit path created with SLSC Switch.lvlib:Connect Channels. Pass this string to SLSC Switch.lvlib:Set Path to establish the exact same path in future connections.

In some cases, multiple paths are available between two channels. When you call SLSC Switch.lvlib:Connect Channels, SLSC Switch selects an available path; however, the driver may not always select the same path through the switch module.

This VI only returns those paths explicitly created by SLSC Switch.lvlib:Connect Channels or SLSC Switch.lvlib:Set Path. For example, if you connect channels CH1 and CH3,and then channels CH2 and CH3, an explicit path between channels CH1 and CH2 does not exist, and an error is returned.

Inputs/Outputs

  • cgenclassrn.png session in —

    session in identifies a particular SLSC Switch session established with SLSC Switch.lvlib:Initialize with Topology and used for this NI-SLSC Switch call.

  • cstr.png channel 1 —

    channel 1 specifies one of the channel names of the desired path. Pass the other channel name as channel 2 .

  • cstr.png channel 2 —

    channel 2 specifies one of the channel names of the desired path. Pass the other channel name as channel 1 .

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrn.png session out —

    session out identifies a particular SLSC Switch session established with SLSC Switch.lvlib:Initialize with Topology and used for this NI-SLSC Switch call.

  • istr.png path —

    path is a string composed of comma-separated paths between channel 1 and channel 2 . The first and last names in the path are the path endpoints. All other channels in the path are configuration channels .

    Examples of returned paths:

    ch0->com0, com0->ab0.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
