Option Description
History size

Contains the number of iterations of the loop to delay the packet of data. The default is 1.

Inputs/Outputs

  • cexpdynwdt.png Signals —

    Contains the input signal or signals.

  • cbool.png Enable —

    Enables or disables the Express VI. The default is ON or TRUE.

  • cerrcodeclst.png error in (no error) —

    Describes error conditions that occur before this node runs.

  • iexpdynwdt.png Delayed Signals —

    Returns the delayed signal(s).

  • ierrcodeclst.png error out —

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

    • The value you wire to History Size determines the number of times the loop iterates before the Express VI returns data. For example, if you enter 1 in History size, the Express VI does not return the data wired to the Signals input after the first iteration of the loop. The second time the loop iterates, the Express VI returns the value from the first iteration of the loop. The third time the loop iterates, the Express VI returns the value from the second iteration of the loop.
