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.

This output is available only if you do not wire group name.

datatype_icon

group name out

Channel group on which you performed the operation.

This output is available only if you wire group name.

If you do not specify a group name, this output returns Untitled.

datatype_icon

group/channel names

Names of the channel groups and their associated channels.

This output is available only if you do not wire group name.

datatype_icon

channel names

Names of the channels associated with the group you specified.

This output is available only if you wire group name.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
