How to Synchronize DAQmx NI 9862 and NI 9239

[rayyang]

Hardware : NI 9178+9862 XNET +9239 Volt-measure.

Software: LabVIEW2015 +Win 7

How acquisition data from 9239 synchronously using a CAN signal from 9862.

I mean get a latest data from 9862 then collect the data from 9239 at the same time

Hello rayyang,

from the example finder use the Synchronize C Series CAN with DAQmx Analog Input.vi as a starting point. The synchonisation is done with the timestamps, because the messages from XNet are asynchronous to the acquisition. The 9239 has a Sigma Delta ADC and a filter delay, which also must be handelt.
