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…
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;
-…
IEC 62541-4:2015 defines the OPC Unified Architecture (OPC UA) Services. The Services described are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. This second edition cancels and replaces the first edition published in 2011. It constitutes a technical revision. It includes the following changes:
- Update for 6.4…
