Or Array Elements Function

Returns FALSE if all the elements in Boolean array are FALSE or if Boolean array is empty. Otherwise, the function returns TRUE. This function accepts an array of any size but returns only a single value based on all values in Boolean array.

The connector pane displays the default data types for this polymorphic function.

Inputs/Outputs

  • c1dbool.png Boolean array —

    Boolean array can have any number of dimensions.

  • ibool.png logical OR —

    logical OR indicates if all of the elements in Boolean array are false.

    • FPGA Module Details

    The following details apply when you use this object in an FPGA VI.

    Note The following details are subject to change with each version of the LabVIEW FPGA Module.
    Single-Cycle Timed Loop Supported.
    Usage For maximum time and resource efficiency, use Boolean functions inside a single-cycle Timed Loop.
    Timing

    Inside single-cycle Timed Loop--When you use Boolean functions inside a single-cycle Timed Loop, each Boolean operation adds slightly to the combinatorial logic delay of the single-cycle Timed Loop.

    Outside single-cycle Timed Loop--When you use Boolean functions outside a single-cycle Timed Loop, each Boolean operation requires one clock cycle.
    Resources Boolean functions consume significant FPGA resources only when you wire a large array to the input. Consider limiting arrays to conserve FPGA resources.
