CPU workload LabVIEW 8.0

[homer_dk]

Im trying to develop an Measurementapplication.

The Application has to query 23 AnalogInputs and 3 CounterInputs and the configuration of the System is:

2,66GHz Pentium 4 with 2GB RAM, 2x PCI 6229 and 1x PCI 6602.

My question.

Is it normal that the System works with an CPU-workload of 100%

Thank you very much

Hello Homer,

please post some more information about your application architecture. Are you using untimed while loops? How do you acqurie data? etc.

Generally it is not normal that the CPU usage is 100%.

Hi,

I acquire the data with 2x PCI 6229 and 1x 6602,

and the Vi is attached

Hi Homer,

as I could see the small while-loop is untimed. As all Sub-VIs are missing I was not able to test the VI but I am sure that the CPU usage will be low when you implement the timing in the small while loop.

Thanks!

implementing a Timeloop has cut the CPU-workload to 65-75%
nice

Typically, you should insert a delay (Wait) within every loop, even a value as small as 1 ms.  I normally use 10ms.
