Several finte Analog Output and Simoultanouse repetative finite Analog Inputs

[johnylowen2004]

Hi guys,

I will appreciate if one helps me to find the correct structure design for the application below.

lets say I have five steps of test:

1.  A1 number of samples of an arbitrary waveform AO                          Collect 1sec of data from an AI at the last B1 number of samples of A1
2. A2 number of samples of another arbitrary waveform AO                   Collect 1sec of data from an AI at the last B2 number of samples of A2
3. A3 number of samples of another arbitrary waveform AO                   Collect 1sec data from an AI every B3 number of samples of A3
4. Repeat 1
5. Repeat 2

For the sequencing of AOs I put a finite analog output in a for loop and put the A1, A2, A3 in an array as the index of loop and put the error handler outside to make sure each loop is done completely (attached figuere). Now I want to start at the given conditions of second column.

I don't know the correct structuring, my devices are as below:

Chassis: cDAQ-9178

AO module: NI cDAQ 9263

AI module: NI cDAQ 9207

I know it is a basic problem as I have recently started to work with NI.

Thanks a lot.

Do not post a picture of a Block Diagram -- post the VI, instead.  We can edit a VI, inspect a VI, modify a VI, test (or run) a VI, but can only glance at a picture and then give up.
