Hi, I would like to ask about how to capture data from real time loop.

Hi,

Here is some overvier of my project:

I have done real time control using labview 9.0. I used PID controller.

In order to optimise this controller, I need to capture data from my sensor(input) and actuator (output).

1. For example while real time control is running. I need to capture 1000 sample data (sensor(input) and actuator (output)).

Then I will used these data for PID optimisation on the other loop without intefere my real time loop.

2. When PID optimisation is completed, I will sent its PID parameter to real time control loop.

3. These operation is done in parallel.

Anybody can help me to solve these. Your idea may solve my problem.

TQ

Typically you will have to use RT FIFO or Queue communication to avoid any impact to your time critical loop.

Best regards
