IEC 61753-1:2018+A1:2020 provides guidance for the drafting of performance standards for all passive fibre optic products. This document defines the tests and severities which form the performance categories or general operating service environments and identifies those tests which are considered to be product specific. Test and severity details are given in Annex A. This second edition cancels…

IEC 62443-3-2:2020 establishes requirements for:<br /> • defining a system under consideration (SUC) for an industrial automation and control system (IACS);<br /> • partitioning the SUC into zones and conduits;<br /> • assessing risk for each zone and conduit;<br /> • establishing the target security level (SL-T) for each zone and conduit; and<br /> • documenting the…

IEC 61804-3:2020 specifies the electronic device description language (EDDL) technology, which enables the integration of real product details using the tools of the engineering life cycle. This document specifies EDDL as a generic language for describing the properties of automation system components. EDDL is capable of describing • device parameters and their dependencies; • device functions…

This document defines the formatting, syntax and semantic rules for describing ? an object oriented interface for using services provided by a coordinator and ? the configuration of virtual devices and the environment for their use.

The purpose of storing IDL data on machine-readable media on the IDL is to: — increase productivity (of data and IDL use), — facilitate electronic data exchange, and — assist in authenticity and integrity validation. This document thus specifies the following: — mandatory and optional machine-readable data; — the logical data structure; — encoding rules for the machine-…

IEC 62541-11:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62541-11:2020 is part of the OPC Unified Architecture standard series and defines the information model associated…

IEC 62541-11:2020 is part of the OPC Unified Architecture standard series and defines the information model associated with Historical Access (HA). It particularly includes additional and complementary descriptions of the NodeClasses and Attributes needed for Historical Access, additional standard Properties, and other information and behaviour. The complete AddressSpace Model including all…
