When at least one of the following start conditions is met, the D2000 Event Handler process starts or generates a request to start the event instance. Starting an event instance will cause the execution of the algorithm defined by a sequence of actions in the ESL language.
Process D2000 Event Handler generates the request to start the script instance during the occurrence of a value change of a logged (starting) object. Starting object is a part of the configuration of an object of Event type and determines a value, or a group of values (in case of structured variables) which are logged. If they are changed, process D2000 Event Handler evaluates, whether the start condition specifies the status of a value, which causes a script instance to start (for example the change of a value into the state Invalid), is met.
