Read-Only

This Tag returns events already received and stored by this Driver. When received, these events are stored internally by this Driver in a FIFO-type (First In, First Out) queue, so that subsequent readings return events received up to that moment, as they are received.

As mentioned earlier, each reading operation triggers a succession of OnRead events in this Tag, allowing to process events stored in this Driver individually, thus emptying the internal queue. For more information about the usage of this Tag, please check topic Tags Reported by Events. The Elements of this Block Tag are the following:

•Element 1: Identifier of a panel (U16)

•Element 2: Qualifier of an event (String)

•Element 3: Code of an event (U16)

•Element 4: Partition (U8)

•Element 5: Port number (U16)

The TimeStamp property of this Block Tag indicates the moment this Driver received an event.
