Inputs/Outputs

  • cdbl.png x

    x specifies the input value.

    This input accepts the following data types:

    • Number
    • Timestamp
    • Analog Waveform

    This input also accepts an array or an array of clusters of the listed data types.

  • idbl.png x+1

    x+1 is the result of x+1. If the input is a time stamp value, this function increments the time by one second. If the input is an enumerated type value, this function increments the last enumerated value to the first.

    Note You can manually configure this function to output data of a type you want. To specify the output data type, right-click the function and select Properties to display the Object Properties dialog box. On the Output Configuration page, click the Representation icon and select the data type you want. A blue coercion dot appears on the output terminal of the function to indicate that you have configured the output data type.
  • 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 If you use this function with the single-precision floating-point data type, refer to the Using the Single-Precision Floating-Point Data Type and Deciding Which Data Type to Use in FPGA Designs topics for resource use, latency, and single-cycle Timed Loop support implications.
    Timing

    Inside single-cycle Timed Loop--When you use this function inside a single-cycle Timed Loop, the combinatorial logic delay is proportional to the number of bits in x.

    Outside single-cycle Timed Loop--When you use this function outside a single-cycle Timed Loop, it takes one clock cycle and uses one register.

    If you use this function with the fixed-point data type, the overflow and rounding modes might impact timing.

    Resources This function requires FPGA resources proportional to the number of bits in x. If you use this function with the fixed-point data type, the overflow and rounding modes might impact resources.
