Creates a path between channel 1 and channel 2. NI-SLSC Switch calculates and uses the shortest path between the two channels. Refer to Setting Source and Configuration Channels for information about channel usage types.

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.

  • ierrcodeclst.png error out —

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

    • Details

    Note Paths are bidirectional. For example, if a path exists between CH1 and CH2, then the path also exists between CH2 and CH1.

    If a path is unavailable between the two channels, SLSC Switch returns the following errors:

    Error Description
    Explicit Connection Exists The channels have already been explicitly connected by calling either this VI or the SLSC Switch.lvlib:Set Path.
    Is Configuration Channel One of the channels is a configuration channel. Error elaboration contains information about which of the two channels is a configuration channel.
    Attempt To Connect Sources Both channels are connected to a source. Error elaboration contains information about the sources connected to channel 1 and channel 2.
    Cannot Connect To Itself Channel 1 and channel 2 are identical.
    Path Not Found No paths between channel 1 and channel 2 are available.
    Resource In Use Channel 1 and/or channel 2 is in use. This error often occurs when one of the channels is set as a configuration channel and is in use or if one of the channels is a common multiplexer channel in use.
