This example demonstrates how to use the RCP Inverse Modulus VI. For a detailed description of this VI and how it operates, please refer to the RCP Inverse Modulus help page.

System Requirements

Please refer to the Rapid Control Prototyping (RCP) Toolkit System Requirements to run this example. This example does not require any other hardware.

Configuring the Example

There is no configuration required to run this VI on a Windows PC. Once the RCP Inverse Modulus Example.lvproj is open, click the RCP Inverse Modulus Example.vi under My Computer and you are ready to execute the example.

Running the Example

Click on the VI Run button or select Run from the Operator menu to start the VI.

In this example, a potentiometer outputs a voltage in the range 5V to 0V for each revolution of the potentiometer shaft, with a voltage discontinuity at each turn. Such discontinuities are a problem for control algorithms. In the Position Signal Chart, examine how the Inverse Modulus VI accumulated output signal (in red) is computed from the wrapping potentiometer signal (in blue) in order to provide a continuous position signal, which is directly usable in feedback control systems.

Click on the Front Panel Stop button to stop the VI.
