So when you are writing LabVIEW code, you really want to make sure you don't have race conditions. A race condition is where one piece of code 'races' with another to see which executes first. To prevent that, you can use the Error in/out. This way, it has to use an order and you know absolutely how things are going to run. It is also helpful to put an indicator somewhere connecting to an error out in case something is erroring out. It is just another debugging tool.

I haven't used the safety VIs yet in my code, but they are used inside other of the WPI VIs
