Standardized categories of asset specific information on health status – OPC Unified Architecture

9.5 Standardized categories of asset specific information on health status

9.5.1 Overview

Although the alarming mechanism of OPC UA is used to indicate asset specific information on the health status, there are common indications of alarms across assets. To standardize the common indications, and leave options for extensibility by companion specifications and vendors, this specification uses the mechanism of the ConditionClassId defined for conditions in OPC 10000-9. In the following, specific subtypes of BaseConditionClassType are defined that should be used as ConditionClassId for specific alarms. Other companion specifications and vendors might add additional subtypes of BaseConditionClassType and might inherit from the types defined in this specification.

9.5.2 ConnectionFailureConditionClassType

The ConnectionFailureConditionClassType is used to classify conditions related to connection failures. It is formally defined in Table 20.
