Overview
The example is to demonstrate how to generate a finite ram signal with a user-defined parameters

Description:
With a defined Analog Output from the user, a ramp signal would be generated with the help of the DAQmx in the waveform
and set by the user with the inquired parameters from the front panel of the VI

Steps to Implement or Execute Code::
To implement this example:

  1. Define the Output Physical Channel
  2. Set the value of the parameters as needed
  3. Run the VI
  4. (Optional) Turn on the Highlight Execution to see the flow of the VI

To execute this example:

  1. Install the required software.
  2. Connect the DAQ hardware that supports the AO features
  3. Confirm the connection with the MAX with TestPanel
  4. Open the VI and refer the Implement Steps

Hello, maybe is too late to send my question to this post but i will make it anyway. Maybe someone can help me.

 

Why the Voltage go up when the ramp is finish? 

It can be evitable? i mean, if i put Initial voltage of 2V, and final voltage of 0, why can stay on 0? 

 

Thanks for your help

Look at the "built array" node where the initial voltage is appended to the voltage ramp. If you remove that part and only wire the ramp to the Y terminal, it will stay at the last value.

Hi, can this code be used for the myRio and if yes how should I set the physical channel.
