Creating virtual datapoints

In Profile Studio, create formulas using datapoints as inputs. These are called virtual datapoints.

NOTE: This feature is only available for an EPAS system.

To create virtual datapoints

SPS2DPS is a DPS type created from an SPS.

  1. Select a location in the Navigation pane below the root node.

  2. In the Virtual datapoints tab, right-click and choose one of the following from the context menu:

    • SPS

    • SPC

    • DPS

    • DPC

    • MPS

    • MV

    • SPS2DPS

      The virtual datapoint appears in the Virtual datapoints tab.

To define virtual datapoint inputs and formulas

  1. Select your virtual datapoint.

  2. In the Configuration pane Virtual datapoints tab, click the Edit inputs button.

  3. In the Information dialog, click OK.

  4. In the Datapoints tab, select a datapoint with an associated profile (in black).

  5. Click the button. The datapoint is associated with the virtual datapoint you created.

  6. Click the Edit formula button.

  7. In the Virtual datapoint editor, define a formula to calculate the virtual datapoint's value from the associated datapoint.

  8. On the Signal quality drop-down list, select one of the following:

    • AlwaysValid: The formula is always valid.

    • ValidIfAllSignalsAreValid: The formula is valid when all signals (input) are valid.

    • ValidIfOneSignalIsValid: The formula is valid when one of the signals (input) is valid.

  9. Click OK.
