Get Channel Name From String

Returns a comma-separated list of channel names from a string index list.

Inputs/Outputs

datatype_icon

session in

Handle that identifies the NI-SCOPE instrument session as previously allocated by Initialize With Options .

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

Default value: No error

datatype_icon

index

Index list for the channels in the session. Valid values are from zero to the total number of channels in the session minus one. The index string can be one of the following formats:

  • A comma-separated list—for example, "0,2,3,1"
  • A range using a hyphen—for example, "0-3"
  • A range using a colon—for example, "0:3 "

You can combine comma-separated lists and ranges that use a hyphen or colon. Both out-of-order and repeated indices are supported ("2,3,0," "1,2,2,3"). White space characters, including spaces, tabs, feeds, and carriage returns, are allowed between characters. Ranges can be incrementing or decrementing.

datatype_icon

session out

Reference to the NI-SCOPE instrument session to pass to the next node in the program.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

datatype_icon

channel name

Returns a string of the channel name(s).

Programming Patterns

Use this node to identify the fully qualified names of channels. Fully qualified channel names are required to access channels in multi-instrument sessions.
