IEC 62541-5:2011 defines the Information Model of the OPC Unified Architecture (OPC UA). 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. Thus, the Information Model defines the AddressSpace of an empty OPC UA server. However, it…

IEC 62541-6:2011 specifies the OPC Unified Architecture (OPC UA) mapping between the security model described in IEC 62541-2, the abstract service definitions, described in IEC 62541-4, the data structures defined in IEC 62541-5 and the physical network protocols that can be used to implement the OPC UA specification.

IEC 62541-8:2011 is part of the overall OPC Unified Architecture (OPC UA) standard series and defines the information model associated with Data Access (DA). It particularly includes additional VariableTypes and complemental descriptions of the NodeClasses and Attributes needed for Data Access, additional Properties and other information and behaviour.

ISO 8625-4:2011 defines general terms relating to control/actuation systems in the field of aerospace fluid systems and components.

ISO/IEC 24791-2:2011 defines the interface(s) that provide operations on radio frequency identification (RFID) tag data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification within the Software System Infrastructure (SSI). Specifically, the interface(s) defined by ISO/IEC 24791-2:2011 provide the following features: full…

ISO 15889:2011 defines the Enhanced Ada SubseT (EAST) language used to create descriptions of data called Data Description Records (DDRs). Such DDRs ensure a complete and exact understanding of the data and allow it to be interpreted in an automated fashion. This means that a software tool is able to analyse a DDR and interpret the format of the associated data. This allows the software to…

ISO/IEC 24791-2:2011 defines the interface(s) that provide operations on radio frequency identification (RFID) tag data including, but not limited to, reading, writing, collection, filtering, grouping, and event subscription and notification within the Software System Infrastructure (SSI). Specifically, the interface(s) defined by ISO/IEC 24791-2:2011 provide the following features: full…

IEC 62442-1:2011 defines a measurement and calculation method of the total input power for controlgear - lamp circuits when operating with their associated fluorescent lamp(s). The calculation method for the efficiency of the lamp controlgear is also defined. This International Standard applies to electrical controlgear lamp circuits consisting only of the controlgear and the lamp(s). It is…

IEC 60534-8-2:2011 includes the method for measuring the sound pressure level due to liquid flow through a control valve and the method for determining the characteristic increase of noise due to the onset of cavitation. It also defines the equipment, methods and procedures for the laboratory measurement of the airborne sound needed to determine these characteristics. Two methods are provided for…

ISO 15765-1:2011 gives an overview of the structure and the partitioning of ISO 15765, and shows the relationships between the different parts. It also defines the diagnostic network architecture. The terminology defined in this part is common for all diagnostic networks and is used throughout all parts of ISO 15765. The diagnostic communication over controller area network (DoCAN) protocol…
