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.
