execution timing

[fabio.intel]

Hi,

I'm working for a datalogging project.

I use a cRIO-9104 with a 9237, a 9215 and a 9233. I use a DMA channel for every mod C. In the RT I have four while loops. One for some operation (loop rate 200ms) and the other three to read data from DMA. I cannot find the loop rate of the last three while loops that can permit to read and save the data on three TDM files.

configuraion

DMA ch0: 16383 elements word length 24bits ; Integer word length -4bits 

DMA ch1: 16383 elements word length 24bits ; Integer word length -4bits 

DMA ch2: 16383 elements word length 20bits ; Integer word length 5bits

Hi Fabio,

I'm sorry but I cannot fully understand.

You cannot find the value of wait time of the while loops? What kind of tests have you done?

Could you post a screenshot of the DMA loop diagram?

Bye,
