Part 1: Terms, definitions and fundamentals

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for
standardization comprising all national electrotechnical committees (IEC National Committees).
The object of IEC is to promote international co-operation on all questions concerning
standardization in the electrical and electronic fields. To this end and in addition to other
activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National
Committee interested in the subject dealt with may participate in this preparatory work.
International, governmental and non-governmental organizations liaising with the IEC also
participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as
possible, an international consensus of opinion on the relevant subjects since each technical
committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted
by IEC National Committees in that sense. While all reasonable efforts are made to ensure that
the technical content of IEC Publications is accurate, IEC cannot be held responsible for the
way in which they are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC
Publications transparently to the maximum extent possible in their national and regional
publications. Any divergence between any IEC Publication and the corresponding national or
regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies
provide conformity assessment services and, in some areas, access to IEC marks of conformity.
IEC is not responsible for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including
individual experts and members of its technical committees and IEC National Committees for
any personal injury, property damage or other damage of any nature whatsoever, whether direct
or indirect, or for costs (including legal fees) and expenses arising out of the publication, use
of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
publications is indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve
the use of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability
of any claimed patent rights in respect thereof. As of the date of publication of this document,

INTRODUCTION
A production system uses an industrial automation and control system (3.1.32) (IACS). The
local automation functions can be performed by a control system (3.1.20) . These can be for
example a distributed control systems (DCS), typically used in industrial automation solution
(3.1.34) of process control applications, programmable logic controller (PLC), typically used in
factory automation solutions, etc. in combination with for example sensors, actors (e.g. drives.
valves). A production system uses an industrial automation application (3.1.33). The industrial
automation application (3.1.33) consists of industrial automation system (3.1.31) with default
values of parameters. A industrial automation solution (3.1.34) has specific parameters
assigned to a device instances.
The overall market for wireless communication solutions spans a range of diverse applications,
with differing performance and functional requirements. Within this overall market, the industrial
automation domain can include:
– process automation, covering for example the following industry branches:
• oil and gas, refining,
• chemical,
• pharmaceutical,
• mining,
• pulp & paper,
• water & wastewater,
• steel,
– electric power such as:
• power generation (for example wind turbine),
• power transmission and distribution (grid),
– factory automation, covering for example the following industry branches:
• food and beverage,
• automotive,
• machinery,
• semiconductor.
Application communication requirements for industrial wireless communication systems are
different from those of, for example, the telecommunications, commercial and consumer
markets. These industrial application requirements are identified and provided in 5G-ACIA white
papers that are referenced by the IEC 63595 [2] series.
The IEC 63595 [2] series provides general requirements for industrial automation and spectrum
considerations that are the basis for industrial communication solutions.
Industrial premises can contain a variety of wireless communication technologies and other
sources of radio emissions.
In industrial automation, many different wireless communication solutions can operate in the
same premises. Different to wired fieldbuses, wireless communication devices can interfere
with others on the same premises or environment, disturbing each other.
The IEC 63595 [2] series is intended to provide considerations on cellular wireless
communication systems according to the specifications of the terrestrial radio interfaces of
International Mobile Telecommunications-2020 (IMT-2020) for being applicable in wireless
communication system of industrial automation plants (see ITU-R M.2150-1: 02/2022 [3]).
IEC CDV 63595-1 © IEC 2026
In Figure 1 a UML class diagram is used to categorize the term "Industrial 5G", along with other
examples of standards for industrial wireless communications. Accordingly, Industrial 5G refers
to a set of functions for wireless data transmission using 5G in industrial automation
applications. In this context, only the 3rd Generation Partnership Project (3GPP) 5G radio
interface technologies (RIT) according to the detailed specifications of the terrestrial radio
interfaces of International Mobile Telecommunications-2020 (IMT-2020) are considered.
The 3GPP is a collaborative project that brings together standardization organizations from
around the world to create globally acceptable specifications for mobile networks. As its name
implies, it was first created to establish such specifications for the third generation (3G) of
mobile systems. It has continued its work for subsequent generations, including the one
considered here, the fifth generation (5G).
As an application of cellular networks in industrial automation, the class "Industrial 5G" inherits
from both class "3GPP5G - RIT" and class "wireless industrial communication".

1 Scope
This Part 1 of the IEC 63595 series [1] provides fundamentals for the specification of wireless
communication systems based on 5G and beyond technologies applicable for industrial process
measurement, control and automation. The basic architecture of a 5G system is presented,
which forms the basis of industrial 5G systems. Essential 5G terms are listed with references
to 3GPP documents. Additional definitions of industrial applications terms are provided. These
definitions are used in the IEC 63595 series [1].
The context of an industrial 5G system is described, from which the requirements for such a
system can be derived. Based on that this document provides a description of the conceptual
model of industrial 5G in the context of industrial production (process and manufacturing)
including interfaces of an industrial 5G communication system to automation systems
(reference interface, configuration interface, monitoring interface) and its parameters.

3.1 Terms and definitions
NOTE The given terms and definitions are not all used in this document; these apply also to other parts of the IEC
63595 [2] series.
3.1.1
5G device
user equipment that is part of a 5G system
3.1.2
5G functions
set of functions standardized by 3GPP for 5G communication and implemented in 5G devices
or 5G network devices
3.1.3
5G network
part of a 5G system that implements radio access network functions and core network functions
3.1.4
5G network device
device that either implements radio access network functions or core network functions or both
IEC CDV 63595-1 © IEC 2026
3.1.5
5G system
cellular network system of the 5th generation and beyond
3.1.6
application adaptation unit
set of functions that manage 5G QoS parameters
Note 1 to entry: Obtain QoS parameters of the application, compare them with QoS parameters of the 5G system,
negotiate QoS parameters between application and 5G system and adjust QoS parameters.
3.1.7
application communication requirements
quantitative requirements specifying the required conditions and the required characteristics of
communication solutions at the reference interface that is met in order to achieve the purpose
of the automation application
[SOURCE: IEC 62657-2 [71] ED3, modified - The term communication interface has been
changed by reference interface and the term wireless deleted.]
3.1.8
availability
ability to be in a state to perform as required under given conditions
Note 1 to entry: Availability considers two states, the up state (available) and the down state (unavailable). All time
intervals, such as administrative delay, are defined either as belonging to one of these two states or are excluded.
(It is to be noted that the definition of dependability (3.1.22) does not refer to “states” as it has a much broader
meaning. See 192-01-22 for further clarification).
Note 2 to entry: Availability depends upon the combined attributes of the reliability (192-01-24), maintainability
(192-01-27), supportability (192-01-31) and the maintenance and support provided.
Note 3 to entry: Availability can also be affected by delays before any maintenance and support action is
recognised. For example, delays due to fault detection time and administrative delay.
Note 4 to entry: Given conditions include aspects that affect availability, such as: mode of operation, stress levels
(see 192-01-37 for examples), environmental conditions, and maintenance defined in the life profile.
Note 5 to entry: Availability may be quantified using measures defined in 192-08, Availability related measures.
