26 DataTypes for minimal error handling for devices without alarm support
26.1 ActiveErrorDataType
The ActiveErrorDataType is used for providing information about an active error in a device. It is used for minimal error handling for devices without alarm support.
| Name | Type | Description |
| ActiveErrorDataType | structure | Subtype of 0:Structure as defined in OPC UA 10000-3 |
Id | 0:String | Unique identifier defined by manufacturer |
Severity | 0:UInt16 | Severity as defined in the BaseEventType (1 = low – 1000 = high) |
Message | 0:LocalizedText | Message giving information about the error |
26.2 ClassifiedActiveErrorDataType
The ClassifiedActiveErrorDataType is a subtype of the ActiveErrorDataType and adds the elements defined in Table 140 for additional information about errors.
| Name | Type | Description |
| ClassifiedActiveErrorDataType | structure | Subtype of ActiveErrorDataType |
SourceNodes | 0:NodeId[] | NodeIds of the Nodes which cause the error. This can be a component of the machine (e.g. temperature zone) or a process parameter expressed as MonitoredParameterType (e.g. temperature) |
Classification | 0:UInt16 | Classification of the error, if a process parameter expressed as MonitoredParameterType is the cause of the error. As values (1 – 8), the same as defined in Table 127 are used. If the error is not caused by a specific process parameter (e.g. failure of an component), Classification = 0. |
