Synchronization three actuator with three sensors

[aranS]

Hi Khalid,

Could you post your vi which you are having issues with so I can get a better idea of what the issue might be please?

Hi arans, 

I have attached the VI However, the problem that i am trying to solve is  about the Daq max.read does not acquire data and also does not generate  the data. I have add the PID control system to tune the resonant frequency with changing the DC voltage. 

Thank you

Hi there,

I think if you essentially want to synchronize your AO and AI tasks (which appears to be where the issues are occuring?) it should be possible to modify this example to your application:

Synchronize Continuous Analog Input/Ouput with DAQmx Base - https://decibel.ni.com/content/docs/DOC-3882

It's written for DAQmx Base; however the triggering concept should still be applicable if you set up this triggering structure in your code using DAQmx VI's and the same trigger references.
