controlling solenoids with USB-6525

[NJGW]

Hi, I am new to Labview and am trying to use a USB-6525 to control six indepedent solenoid valves.  They will be switching on and off at different frequencies to control a cell perfusion system.  I have designed a block diagram that allows me to set the times that the SSR is closed and open.  The routine is inside a While loop to repeat until a given time has elapsed.  I can duplicate this six times to allow each valve to be operated independently.  But I would like to trigger all tasks at the same time.  How can I synchronize the loops so they all start at the same time?  Will it suffice to put all loops inside a conditional loop, or will this run the tasks sequentially?

Thanks

your can synchronizeyour while loops using notifiers, please see the attachment.
