===== Detailed Function Description =====

The block is a simplified version of the [[en:mervis-ide:35-help:035-software_basic:060-libraries:060-lib-mervis:020-measurement-and-control:010-alarms:015-alarmsaggregator|Alarms Aggregator]], with the alarm inputs removed. For these, you can use one of the extender blocks.
