IEC 62451-8:2015 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 complementary descriptions of the NodeClasses and Attributes needed for Data Access, additional Properties, and other information and behaviour. This second edition cancels and replaces…
Architecture unifiée OPC - Partie 8: Accès aux données
L'IEC 62541-8:2015 fait partie intégrante de la série de normes générales sur l'Architecture Unifiée OPC (OPC UA). Elle définit le modèle d'informations associé à l'Accès aux Données (DA). Elle comporte notamment des Types de Variables (VariableTypes) supplémentaires et des descriptions complémentaires des Classes de Noeuds (NodeClasses) et des Attributs (Attributes),…
OPC Unified Architecture - Part 9: Alarms and conditions
IEC 62541-9:2015 specifies the representation of Alarms and Conditions in the OPC Unified Architecture. Included is the Information Model representation of Alarms and Conditions in the OPC UA address space. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following changes:
- added section to describe…
Architecture unifiée OPC - Partie 9: Alarmes et conditions
L'IEC 62541-9:2015 spécifie la représentation des Alarms (alarmes) et des Conditions dans l'architecture unifiée OPC, y compris la représentation du Information Model (modèle d'informations) relative aux Alarms et Conditions dans l'espace d'adresses d'OPC UA. Cette deuxième édition annule et remplace la première édition parue en 2012. Elle constitue une révision…
Plasma display panels - Part 2-6: Measuring methods - APL dependent gamma and colour characteristics
IEC 61988-2-6:2015(E) defines the measuring methods for gamma and colour gamut characteristics as a function of the APL for a PDP module (plasma display module). Generally, the luminance level of a PDP module is dependent on the APL (average picture level) of input images. Varying the input levels causes a change of the chromaticity of RGB primary colours. This standard also defines the measuring…
Plasma display panels - Part 4-1: Environmental testing methods - Climatic and mechanical
IEC 61988-4-1:2015(E) defines the following test methods for evaluating the climatic and mechanical endurance characteristics of plasma display modules (PDP modules): temperature and humidity tests, air pressure tests and mechanical tests.
IEC 61747-20-2:2015(E) gives the details of the quality assessment procedures and provides general rules for the visual inspection of the non-active and active areas of monochrome matrix liquid crystal display modules by the human eye and, if necessary, through an optical microscope. Furthermore this standard includes the defect definitions and the method for visual defect inspection. This first…
OPC unified architecture - Part 3: Address Space Model
IEC 62541-3:2015 describes the OPC Unified Architecture (OPC UA) AddressSpace and its Objects. It is the OPC UA meta model on which OPC UA information models are based. This second edition cancels and replaces the first edition published in 2010 and constitutes a technical revision. It includes the following changes:
- Added rules for subtyping enumerations;
- Added Property EnumValues;
-…
