Hi, First post here, seems like a simple one, but I haven't found a good answer yet, so here goes. I'm writing a vi to control a vacuum system with about 20 valves and 10 gauges, and I've been trying to figure out a somewhat neat way to check valve states, user input and open/close the valves without having little case structures for every valve. It's the same basic command for every valve, just with different address information. I'd also like to figure out how to send commands to the valve only when it's state needs to change. To this end I've been playing with event structures, but it seems like I'll need a case for every valve transition. No need to code anything up, just some hints or directions to look into would be really helpful. TIA, -Brett
