Data acquisition with time stamp

Question

Hi I'm using NI DAQ 6211 to acquire acceration, strain and temperature from a VI. I have made several modifications and my last two vis are attached. I need to get 1000 data points from a encoder and sampling the period is by far the best way to get acceleration considering my hardware. 
Is there a way to ensure that all three variables are synchronised within a timestamp without the vi slowing down?
Sincerely
Ahmad

Answer 1

The problem lies in synchronising the acceleration with the load and temperature. For acceleration I'm getting a period from a counter with Implicit values (i.e. without specifying timing). I have set the number of samples to acquire to 1000 points and this task does not require sample timing. Post processing the period data in matlab gives me the acceleration.
Now my vi uses a Sample Clock with set number of samples being acquired for the load and temperature. This means that a set number of samples for load and temperature can be acquired and this time may not be enough to acquire the acceleration points; hence they cannot be mapped in time.
The period is implicit and I can't find a way to synchronise with the load and temperature that are acquired at a fixed sample rate. The bottle neck in this problem is to get the acceleration (period recorded) in sync with the load and temperature. If this can be done without any compromise to the speed of the vi then this problem is resolved.
I have attached the vis which will show the development to overcome this problem.
