myrio dataacquisition and stepper control

[smurfburf]

Hi, 

I am planning to use myRIO both as a data-acqusition device from sensors (to measure wind speed, rotor rpm) and as a control device for stepper motor (which is driven on the basis of the measured values of sensors using pi control). Do I have to use FPGA functionality of myRIO to achieve the dual purpose, or can I do it normally as well?

Hi smurf,

you can use the FPGA, but you can also use it "normally"…

Hi GerdW,

So if I use the 'normal' RT processor to do this, won't my data measurements be delayed while my stepper motor is moved?

Also are there any specific advantages of using one over other?

Thanks,

Which sample rates are you looking for?

You may use several loops to handle DAQ/AI and the stepper motor in parallel…

Also are there any specific advantages of using one over other?

The FPGA runs more deterministic…
