Event Capture

[olsonj112]

In my application I am monitoring a series of sensors that are binary on or off. I need to somehow capture the event where one sensor goes from on to off. Any advice on how this can be done? I'm running LabVIEW 7.1 and windows 2000

Thanks,

J

hi,
You must be using some D I/O card to monitor these sensors,so all you have to do is use the read D I/O vi and get the status of the sensor and use a simple case loop for any action to be taken when the sensors go High or Low.
Hope this helps
cheers

Just do a AND operation between the previous value of the sensor ant NOT the new value. See the attached example.
