4.1 General ToC Previous Next

This standard defines an Information Model for Conditions, Dialog Conditions, and Alarms including acknowledgement capabilities. It is built upon and extends base Event handling which is defined in OPC 10000-3, OPC 10000-4 and OPC 10000-5. This Information Model can also be extended to support the additional needs of specific domains. The details of what aspects of the Information Model are supported are defined via Profiles (see OPC 10000-7 for Profile definitions). Some systems may expose historical Events and Conditions via the standard Historical Access framework (see OPC 10000-11 for Historical Event definitions).
