WSN Node minimum scan rate

[Gevorg]

Hi all,

I'm using a WSN-3212 non-programmable node in my application.

I read the channels of the node in my cRIO real-time application using NI 9795 c-series module.

When I first run my software, it was updating the DIO channels every 5s. After that I changed the scan interval of both WSN and Scan Engine to 100ms.

As a result the channels were updating every 3s.

Does anyone know, how to decrease the scan rate of a WSN node to 100ms?

Is there any minimum rate for WSNs?

Guys, any prompt response will be highly appreaciated.

Thanks in advance.

Hi Gevorg, 

According to page 27 of the WSN-3121 Manual the minimum sampling rate is 2s.  So you won't be able to decrease the rate any lower than this.
