Adding a Calculated Channel

Last Modified: June 15, 2020

Produce a new value based on calculations performed on other channels in the system using the Mapping Diagram.

You can also use System Explorer to add a calculated channel.
  1. Open VeriStand.
  2. In the VeriStand Editor, click Project Files.
  3. Right-click your system definition file (.nivsdf) and select Mapping Diagram.
  4. On the Mapping Diagram, click the Software palette and drag a calculated channel onto the diagram.
    Calculated channel Description
    Formula Calculates the result of the formula you specify.
    Maximum Compares two values and returns the larger value.
    Minimum Compares two values and returns the smaller value.
    Lowpass Filter Applies a lowpass Butterworth filter to the input channel.
    Peak and Valley Calculates the peak, valley, and offset of a cyclical waveform produced by the input channel. This calculation is performed by running the incoming value through a lowpass Butterworth filter and comparing the filtered value to previous maximum and minimum values.
    Acceleration Calculates the acceleration and velocity of the input channel.
    Average Calculates the average value of the input channel.
    Conditional Compares X with Y based on the configured condition. This channel outputs W for true and Z for false.
  5. Use the Configuration pane to configure the calculated channel.
  6. Save the system definition file.
