    datatype_icon

    tdms file

    A reference to a .tdms file. Use the TDMS Open node to obtain the reference.

    datatype_icon

    group name

    Channel group to analyze.

    If you do not wire group name, this node performs the operation on all channels and groups.

    datatype_icon

    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

    tdms file out

    A reference to the .tdms file.

    datatype_icon

    group names

    Names of the channel groups in the .tdms file.

    group names is not available if you wire group name.

    datatype_icon

    group name out

    Channel group on which you performed the operation.

    group name out is available only if you wire group name.

    datatype_icon

    group/channel names

    Names of the channel groups and their associated channels.

    group/channel names is not available if you wire group name.

    datatype_icon

    channel names

    Names of the channels associated with the group you specified.

    channel names is available only if you wire group name.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
