This part of the IEC 61784-3 series explains some common principles that can be used in the
transmission of safety-relevant messages among participants within a distributed network
which use fieldbus technology in accordance with the requirements of IEC 61508 (all parts) 1
for functional safety. These principles are based on the black channel approach. They can be
used in various industrial applications such as process control, manufacturing automation and
machinery.
This part and the IEC 61784-3-x parts specify several functional safety communication
profiles based on the communication profiles and protocol layers of the fieldbus technologies
in IEC 61784-1, IEC 61784-2 and IEC 61158 (all parts). These functional safety
communication profiles use the black channel approach, as defined in IEC 61508. These
functional safety communication profiles are intended for implementation in safety devices
exclusively.
NOTE 1 Other safety-related communication systems meeting the requirements of IEC 61508 (all parts) can exist
that are not included in IEC 61784-3 (all parts).
NOTE 2 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such
as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.
All systems are exposed to unauthorized access at some point of their life cycle. Additional
measures need to be considered in any safety-related application to protect fieldbus systems
against unauthorized access. IEC 62443 (all parts) will address many of these issues; the
relationship with IEC 62443 (all parts) is detailed in a dedicated subclause of this document.
NOTE 3 Implementation of a functional safety communication profile according to this document in a device is not
sufficient to qualify it as a safety device, as defined in IEC 61508 (all parts).
NOTE 4 The resulting SIL claim of a system depends on the implementation of the selected functional safety
communication profile within this system.
NOTE 5 Annex C explains the numbering scheme used for the technology-specific parts (IEC 61784-3-x) as well
as their common general structure.
NOTE 6 Annex D provides a guideline for the assessment and test of safety communication profiles as well as
safety-related devices using these profiles.

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 document defines a set of protocol specific communication profiles based primarily on the IEC 61158 series, to be used in the design of devices involved in communications in factory manufacturing and process control. Each profile selects specifications for the communications protocol stack at a device. It contains a minimal set of required services at the application layer and specification of options in intermediate layers defined through references. If no application layer is included, then a minimal set of required services at the Data-link layer is specified. The appropriate references to the protocol specific types are given in each communication profile family or associated profiles.

IEC 62872-1:2019(E) defines the interface, in terms of information flow, between industrial facilities and the “smart grid”. It identifies, profiles and extends where required, the standards needed to allow the exchange of the information needed to support the planning, management and control of electric energy flow between the industrial facility and the smart grid.
The scope of this document specifically excludes the protocols needed for the direct control of energy resources within a facility where the control and ultimate liability for such control is delegated by the industrial facility to the external entity (e.g. distributed energy resource (DER) control by the electrical grid operator).

This document, as a basis for the other parts of the ISO 15118 series, specifies terms and definitions,
general requirements and use cases for conductive and wireless HLC between the EVCC and the SECC.
This document is applicable to HLC involved in conductive and wireless power transfer technologies in
the context of manual or automatic connection devices.
This document is also applicable to energy transfer either from EV supply equipment to charge the EV
battery or from EV battery to EV supply equipment in order to supply energy to home, to loads or to
the grid.
This document provides a general overview and a common understanding of aspects influencing
identification, association, charge or discharge control and optimisation, payment, load levelling,
cybersecurity and privacy. It offers an interoperable EV-EV supply equipment interface to all e-mobility
actors beyond SECC.
The ISO 15118 series does not specify the vehicle internal communication between battery and other
internal equipment (beside some dedicated message elements related to the energy transfer).
NOTE 1 Electric road vehicles specifically are vehicles in categories M (used for carriage of passengers) and
N (used for carriage of goods) (compare ECE/TR ANS/WP.29/78 ev.2). This does not prevent vehicles in other
categories from adopting the ISO 15118 series as well.
NOTE 2 This document is destined to orientate the message set of ISO 15118-2 and ISO 15118-201). The
absence of any particular use case in this document does not imply that it will not be put into practice, with the
required messages.
NOTE 3 This document, ISO 15118-2 and ISO 15118-20 are designed to work independent of data transfer
medium used. However, the ISO 15118 series is made for fitting the specified data link layers in the corresponding
documents in this series.

This part of IEC 62443 specifies a comprehensive set of requirements for security capabilities for IACS service providers that they can offer to the asset owner during integration and maintenance activities of an Automation Solution. Because not all requirements apply to all industry groups and organizations, Subclause 4.1.4 provides for the development of Profiles that allow for the subsetting of these requirements. Profiles are used to adapt this document to specific environments, including environments not based on an IACS. NOTE 1 The term “Automation Solution” is used as a proper noun (and therefore capitalized) in this part of IEC 62443 to prevent confusion with other uses of this term. Collectively, the security capabilities offered by an IACS service provider are referred to as its Security Program. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner. NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related. Figure 2 illustrates how the integration and maintenance capabilities relate to the IACS and the control system product that is integrated into the Automation Solution. Some of these capabilities reference security measures defined in IEC 62443-3-3 that the service provider must ensure are supported in the Automation Solution (either included in the control system product or separately added to the Automation Solution).
