Scope

IEC 62541-5.2015 defines the Information Model of the OPC Unified Architecture. The Information Model describes standardised Nodes of a Server's AddressSpace. These Nodes are standardised types as well as standardised instances used for diagnostics or as entry points to server-specific Nodes. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. This edition includes the following changes:

- Defined ProgressEventType;

- Defined DataType called BitFieldMaskDataType;

- Delete Property SamplingRateCount in ServerDiagnosticSummaryDataType;

- Added the Property "EffectiveTransitionTime" to TransitionVariableType;

- Introduced VariableType OptionSetType;

- Added a new EventType called SystemStatusChangeEventType;

- Added properties to ServerCapabilitiesType. Added an object for operation limits. Added type OperationLimitsType containing that information;

- Added SecureChannelId to AuditActivateSessionEventType;

- Added normative Annex C defining FileType and Methods;

- Added a Method GetMonitoredItems on ServerType;

- Removed the concept of ModelParent. Added meta data for namespaces in ServerType and created types for managing that. Added representations for ModellingRules OptionalPlaceholder and MandatoryPlaceholder;

- Added new types NonTransparentNetworkRedundancyType, NetworkGroupDataType and EndpointUrlListDataType.
