This condition is to be used when you want to detect when the state of a value changes. You can use this with the If, Then, Otherwise actions to make actions happen when your value changes to different states.
When using this condition, you define a value that you want to check when it changes, and anytime it does change, the behaviour will trigger.
Example: If your value is a Digital Output, your behaviour will trigger when the output channel changes from On to Off, or from Off to On. If your value is an RFID Reader, your behaviour will trigger when it changes from “Tag 1” to “None” (when a tag is removed), or from “None” to “Tag 2”. If your value is a Number Variable, it will trigger when it changes from 1 to 2, 2 to 3, or 3 to 0.
