About OPC Alarm and Event Collector

The OPC Alarm & Event Collector collects alarm and event data from an OPC Alarm & Event compliant server (such as CIMPLICITY), and stores it alongside Historian process data. Like other collectors, the OPC Alarm & Event Collector is created when Historian is installed, based on the OPC Alarm & Event servers available.

For more information about configuring the OPC Alarm & Event Collector, refer to the topics in section.

The OPC Alarm & Event Collector does not support pre-processing raw data with Python Expression Tags during collection.
