control and simulation loop: Timing Parameters

[keshavsew]

Hello,

Is there any way of accessing a time source greater than 1KHz in timing parameters, Control and Simulation loop, without using Real Time targets? For example using cpu timing.

I am using NI myDAQ for data aquisition, and i need a timing source of approximately 100KHz.

Thank you very much.

Regards,

Keshav

No. When running on a PC class computer you are working with a set of standard hardware (with its 1 kHz clock) and a non deterministic OS, and there is nothing you can do about it.This is why the NI acquisition boards are all smart devices with their own processors, memory and clocks.

Thank you very much for you reply mike.

I will try to use GPIB instead. 🙂

What??

Where did GPIB come into the mix? How will going to GPIB address clocks?

Hello,

Actually i need to perform a hysteresis current control on a single phase grid tied inverter. I was trying to perform the acquisition of current and generate pwm through myDAQ. But unfortunately myDAQ is not able to track my current. Because myRIO in GBIP offers real time target, can it be used to perform the task instead?

Thank you 🙂
