DataSubscriber question
« on: April 13, 2015, 04:37:12 PM »
I'm very new to VB programming, as well as being new to AdvancedHMI.  So with that said is there a way to record a value with the datasubscriber only on data change.   I don't care about poll rate just need it to record when the watched value changes.  Or might there be a better way?

Thanks so much.
Dave

You may want to use the BasicDataLogger. It records values to a text file either based on time or based on a change.
