This event type is executed when the connected variable is updated, independently of the time point of execution.
There are five usable triggers.
Scripts that are run by a trigger event can use these System Variables.
|Type of trigger||Description|
|On Change||The event is executed whenever the variable changes.|
|On Update||The event is executed for every received variable value. It is also run when the received and the current value are identical.|
|On Limit Drop/On Limit Exceed (Option "Execute subsequent events")||The event is executed when the value of the variable drops below or rises above a threshold. The threshold is set in the field "Value".|
|On specific Value (Option "Execute subsequent events")||The event is executed when the variable reaches a specific value that is specified in "Value".|
Execute subsequent events
Trigger once on repeatedly fulfilled condition: The event is executed once. The event can only be executed again after the condition was not fulfilled at least once. After it was not fulfilled, dropping below, rising above, or reaching the specified value executes the event again.
Trigger every time on repeatedly fulfilled condition: The event is executed on every variable update as long as the condition is fulfilled.
