How to measure, control and log data in the same time?

[BrainDrain]

Dear Labview experts.

I have rather basic question. How can I measure, control and log data simultaniously?

We have build an application, where we control an angle using a variable resistor. The input is simply a voltage which is scaled and compared with an reference  values. The measuremen and control of the angle

works fine. However, I would like to monitor the input port (and log the data) independently of the control loop. How can this be achieved?

Many thanks for your help!

Try use something like this:

Make few queue for sending data from measure thread to control thread and next queue to sending data from control to logging.

Many thanks for the fast response. I will try it that way.
