waveform generation

I am trying to generate a waveform for 4 relays. I have the for loop. I am not sure how I can start the next sequense. I need the timing to overlap for the second, third and fourth wave. I am trying to balance a pressure line for testing.

 

 

I am currentlt using a 6215 DAQ. I am using the digital output. I have 4 lines that I am using. I just can't get the waves to overlap.

Is this all you need?

Thanks for the feedback. I was able to generate the same logic with signal express. But I was not succesfull in the intersection of the turn OFF and the turn ON for the next wave.

Are you developing this with LabVIEW or with LabVIEW Signal Express?  Also, what level of synchronization are you looking for between your channels... is it necessary to have the rise and fall times overlap?  A little more information regarding the timing of these signals would be helpful.

 

Thanks!

I decided to purchase a DAQ card with hardware controller I/O lines. I was unable to get precise timing. I have other events happenibg at the same time.

 

Thank You,
