Abort Time Delay

[ajcooke]

Hello,

I have encountered an issue I was hoping I could recieve some input on. In my VI that I am creating, we have a series of valve opening and closing followed by time delays to allow for a reaction to occur. However, in terms of saftey while these reactions are going on there is a risk of pressure build up. I want to be able to abort the time delay early when the high pressure alarm is triggered. From here the program would ideally enter a "shutdown" mode to diffuse the pressure build up.

Thanks

Use short delays and continuously check for your shutdown criteria.  The Elapsed Time VI will help a lot here.  This is pretty simple to do with a good state machine.
