Changing states based on time elapsed

[AbeLinkkin]

Hello everyone. I am new to Labview and am having a problem figuring out how to set up my VI to change states based on a time delay. The system should work like so.

 I have a case structure with that goes into 1 of the following 4 states based on how much time has elapsed since the cycle started.

between 0 and 4 seconds motor one needs to be running  

between 4 and 6 seconds motor one and two need to be running

between 6 and 15 seconds only motor two is running

between 15 and 30 seconds both motors are off

after 30 seconds have passed the cycle starts over and the process repeats.

I tried using the Elapsed Time VI but cant seem to get it to work.

Any suggestions are greatly appreciated.

I am using Labview version 8.2

Thanks

It is difficult to help you figure out why your VI doesn't work if you don't post the VI.

Hi Abe,

I have attached a small vi that will do what you ask. It is very simple, if you plan on adding extra functionality to this project then i would suggest starting with a different architecture. Look at Producer/Consumer architectures, especially if you are going to be adding any user interface actions. As i said the vi i have attached will do what you have asked but no more.

Hope this helps.

Rgs,
