 +**Note:** Since release 7.1, there is a [[time event]] block which should be used for events that are time-related.
  
 Discrete events are used by various blocks in order to trig an action. The [[Snapshot|snapshot]] block uses a discrete event in order to trigger the snapshot, the [[Transfer|transfer]] block can specify a discrete transfer by referencing a discrete event. Discrete events are used by various blocks in order to trig an action.

 During the simulation an event is triggered when the //sign// of the //difference// of the left hand side expression and the right hand side expression changes between two time points. In other words; for every time step taken, ''%%sign(leftexpression-rightexpression)%%'' will be checked. As explained in the introduction, when the sign changes the solver will backtrace to a time point when the two sides are equal. During the simulation an event is triggered when the //sign// of the //difference// of the left hand side expression and the right hand side expression changes between two time points.
