Conveyor Delay

[Nickargo]

I am new to VisiLogic, and trying to navigate through what I thought was a simple task on a V430 HMI PLC.  I have a conveyor with a sensor on one end and a sprayer in the middle.  I simply need to shift or delay my sensor on signal so that the sprayer sprays when it is under the sprayer.  I was able to accomplish this through a complicated mess of timers and bits.  The problem is if another item passes the sensor while the timers are running, it ignores the part.  I would normally use a shift register on other plc platforms, but can't for the life of me seem to find the right information on doing this or getting anything to work.  I am sure that there is a simple solution to this but my inexperience with the differences in VisiLogic are holding me back.  Please help.

My standard solution (thanks to Joe Tauser)...

You can place to MI905 distance to gun in pulse.

Then symply check last bit (MI(1000+DIST TO GUN)) in FIFO STACK.  If this bit =1 then  Gun =  Enable.

Thank you, I believe this is the ticket.  I knew there must be an easier way then what I was doing.    I will try it out and see how it goes.
