Hello everyone ,I am using NI 9189 chasis, along with 9205,9263,9472.
During aquring the data over the ethernet i am not getting more than 10Hz. For my applicaton I need at least 100 Hz data from the chasis with real time.
when I have tried to increse the frequency of the system. I am getting that data with a delay of 2-3 seconds.
Help me to solve this.
I am working on a close loop control system, where I need a real time data in high frequency.
Thanks in advance

Unfortunately, Ethernet communication has milliseconds of latency. (Instrument Bus Performance – Making Sense of Competing Bus Technologies for Instrument Control)
When using cDAQ-9189, the data are sent to your host PC to process.
If you want to do closed-loop control, you should use cDAQ-913x or cRIO with standalone controller.

Can you share the code ? From your description, it's difficult to make any assessment. Please share for LV 2020
