IEC 62541-7:2020 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 62541-7:2020 defines the OPC Unified Architecture (OPC UA) Profiles. The Profiles in this document are used to segregate features with regard to testing of OPC UA products and the nature of the testing (tool based or lab based). This includes the testing performed by the OPC Foundation provided OPC UA CTT (a self-test tool) and by the OPC Foundation provided Independent certification test labs. This could equally as well refer to test tools provided by another organization or a test lab provided by another organization. What is important is the concept of automated tool-based testing versus lab-based testing. The scope of this standard includes defining functionality that can only be tested in a lab and defining the grouping of functionality that is to be used when testing OPC UA products either in a lab or using automated tools. The definition of actual TestCases is not within the scope of this document, but the general categories of TestCases are within the scope of this document. Most OPC UA applications will conform to several, but not all, of the Profiles. This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new functional Profiles: - profiles for global discovery and global certificate management; - profiles for global KeyCredential management and global access token management; - facet for durable subscriptions; - standard UA Client Profile; - profiles for administration of user roles and permissions. b) new transport Profiles: - HTTPS with JSON encoding; - secure WebSockets (WSS) with binary or JSON encoding; - reverse connectivity. c) new security Profiles: - transportSecurity - TLS 1.2 with PFS (with perfect forward secrecy); - securityPolicy [A] - Aes128-Sha256-RsaOaep (replaces Base128Rsa15); - securityPolicy - Aes256-Sha256-RsaPss adds perfect forward secrecy for UA TCP); - user Token JWT (Jason Web Token). d) deprecated Security Profiles (due to broken algorithms): - securityPolicy - Basic128Rsa15 (broken algorithm Sha1); - securityPolicy - Basic256 (broken algorithm Sha1); - transportSecurity - TLS 1.0 (broken algorithm RC4); - transportSecurity - TLS 1.1 (broken algorithm RC4). e) deprecated Transport (missing support on most platforms): - SOAP/HTTP with WS-SecureConversation (all encodings).

Specifies process requirements for the secure development of products used in industry automation and control systems. It defines a secure development life-cycle (SDL) including security requirements definition, secure design, secure implementation (including coding guidelines), verification and validation, defect management, patch management and product end-of-life. These requirements can be applied to new or existing processes for developing, maintaining and retiring hardware, software or firmware for new or existing products. These requirements apply to the developer and maintainer of the product, but not to the user of the product.

IEC/TR 62837:2013(E) provides to the technical committees a framework for the development and adaptation of documents in order to improve energy efficiency in manufacturing, process control and industrial facility management.

IEC 61406-1:2022 specifies minimum requirements for a globally unique identification of physical objects which also constitutes a link to its related digital information. This identification is designated hereinafter as "Identification Link" (IL), with the encoded data designated as IL string. The IL string has the data-format of a link (URL). The IL is machine-readable and is attached to the physical object in a 2D symbol or NFC tag. The requirements in this standard apply to physical objects: - that are provided by the manufacturer as an individual unit, - and that have already been given a unique identity by the manufacturer. This document does not specify any requirements on the content and the layout of nameplates/typeplates (e.g. spatial arrangement, content of the plain texts, approval symbols etc.).

IEC 61406-2 complements IEC 61406-1 with specific rules for encoding characteristics of marked physical objects when relevant. This includes cases where the uniqueness of the Identification Link string is not limited to relating only to an individual item but may alternatively relate to a product type, lot or batch. 

This part 3 of the IEC 63278 series aims at the secure and interoperable exchange of information between stakeholders in value chains. This includes how integrity, authenticity, and confidentiality are realized within the AAS information model. It refines AAS security requirements from IEC 63278-1 affecting the structure of the information model as defined in IEC 63278-2 NP and defines the respective security information model complementary to IEC 63278-2.

This document describes a framework of trust for the processing of multi-sourced data that includes data use obligations and controls, data provenance, chain of custody, security and immutable proof of compliance as elements of the framework.
