Event Counter (BOOL)

[coolhandLV7]

Hello, I am trying to count the number of times a signal goes from 0 to 1 from a digital input (cDAQ 9375).  Seems like an event structure is perfect for this, but once I started experimenting with the concept using (value signaling) property node, it doesn't work.  I've attached what I have so far as a first attempt, if anyone has a better idea or can explain the best way to count state changes from a DOUT IO card I'd appreciate it.

Events are for user interactions and having a value change event that fires with each iteration is pointless (signaling properties fire even if the value does not change!).

Since you are polling a DI, you don't need any event structures at all. Just use a feedback node that increments whenever the boolean goes from false to true.

A counter should be blue, not orange. Why is there a timeout event if you are not using it?

See if this can give you some ideas...
