Is it possible to detect a change in the value of a NI 9402 Digital Output line using a LabVIEW event structure?

Why a DO, DO will change its output based on your data, if you can intervene and check the data, you don't even need an event structure.

Thanks! I am currently polling the data, and thought that an event structure might increase response time or make the code more efficient. I know I can use value signal with an indicator, but didn't see any way to utilize the event structure to trigger directly off a DO. 🤔
