shared variable sampling rate

Hi, I would want to read some shared variable on the network at 1KHz on SignalExpress but I'm actually limited at 200Hz on it.

 

Is there any possibility or not?

 

Thanks.

Hi pattegain,

 

I'm not sure reading shared variables published on the network at 1kHz is possible. 

 

I suggest you to read this :

 

Buffered Network-Published Shared Variables: Components and Architecture

 

http://zone.ni.com/reference/en-XX/help/371268P-01/expresswb/read_shared_variable_se/

 

However, I tried the Shared Variable Examples (Reader and Writer) and I have been able to run the Reader with 0,002 sec (500Hz) as Sample Period parameter. Did you test those examples?

Re : shared variable sampling rate

Thank you!

 

I've already test to reduce the sampling period to 0.002s but there is an alert in SE saying "Sampling period too low" but it's work.

 

So I understand that the minimum accptable sample in SE is 200Hz. 

 

 

Many thanks!!

 

Regards.
