analogue input output

[stagger lee]

building a vi to output a waveform (ramp) to provide control for a loadframe. at the same time time i need to acquire data generated from various transducers. i'm using two synchronised loops, one for output and the other for input. i get my ramped output o.k, but no acquired signal on the input channel. i've attached my code to try and help see what i'm doing, rightly or wrongly? any pointers much appreciated.
thanks in advance.

Can you post the code that is acquiring data from transducers?  What you posted only does the ramp generation.

Stagger,

Have you tried to placing your data acquisition code within the Voltage ramp loop?

ah, sorry, uploades the wrong code. i've attached the code with apparent acquisition added. i'm going about it with two synchronised loops.
i will try adding the acquisition code inot the ramp generation loop too.

thanks in advance.

o.k, i placed my acquisition code into the timed loop of the ramp generator, i also changed the specification of the daqmx read, and i now have somehting that works that i can build on.
thanks again for ideas/pointers.
