When at least one of the following start conditions is met, process D2000 Event Handler 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 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 specifying
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.
