AMENDMENT 1
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) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 1 to IEC 61918:2018 has been prepared by subcommittee 65C: Industrial networks,

of IEC technical committee 65: Industrial-process measurement, control and automation.

The text of this Amendment is based on the following documents:

4.2.3.2 Use of the described environment to produce a bill of material
Add, before Figure 7, the following sentence:

The planner, when consulting the device and cabling manufacturer, shall take into account the

guidance provided in Clause B.6 for the correct selection of the device and cabling in relation

to the environment EMI of the installation under consideration.
4.3.2.1 General
Add, at the end of the subclause, the following text:

Media types consist of optical fibre cabling, balanced cabling (4-pair, 2-pair, 1-pair), wireless,

and other CP specific media types. Wireless network installation is not within the scope of this

document. Selection of physical media technologies should partner with architectural

considerations, taking into account network topology, network characteristics, as well as data

propagation and aggregation throughout the network.

Optical fibre is generally recommended where high bandwidth is needed or a high data integrity

is required. Where powering is required or for reduced bandwidth or length compared to optical

fibre, wire cabling is recommended. 4-pair is mostly recommended for connecting control and

automation equipment. 1-pair (see Annex Q) is mostly limited to connecting control and

automation equipment with field devices.

The planner should take into account EMI performance when selecting cabling types and

spacings from types of conductors. In practice, need for EMI reduction equates to increase in

spacing, which can translate to installation cost. Failure to consider EMI performance and

mitigations can ultimately lead to areas of high disturbance at critical points in the network.

Comparative measurements (unshielded versus shielded) have shown that shielded

constructions can provide a higher level of protection against EMI when applied according to

equipment manufacturers specifications.
4.3.2.3 Network characteristics for balanced cabling based on Ethernet
Add, at the end of the subclause, the following text:
For balanced 1-pair networks, the requirements specified in Annex Q apply.
4.4.1.2.1 Balanced cables for Ethernet-based CPs
Add, after the first sentence, the following text:
For balanced 1-pair cables, the requirements specified in Annex Q apply.

Replace, in the fourth bullet, "cabling that uses mixed 2 and 4 pair cable elements in the same

channel" with "cabling that uses cable elements with a different pair count in the same channel

(e.g., 2- and 4-pair or 1- and 4-pair),"

The requirements specified in Clause 4, Clause 5 and Clause 6 fully clarify the mitigation

measures to be used for the cabling. In this Annex B, some additional clarifications are provided

in regard to the selection of the proper communication devices and cabling.

Communication devices are available with different constructions in order to serve a large range

of different applications. The most critical impact of the industrial environment EMI on the

devices is the saturation of the device physical layer interface with the cabling, which happens

when the common mode (CM) voltage tolerance of the devices is less than the impact of the

conducted disturbances.
Typically, the level of the CM voltage tolerance

8 AMENDMENT 1
10 FOREWORD

11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

12 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

13 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

14 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

15 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

16 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

17 in the subject dealt with may participate in this preparatory work. International, governmental and non-

18 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

19 with the International Organization for Standardization (ISO) in accordance with conditions determined by

20 agreement between the two organizations.

21 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

22 consensus of opinion on the relevant subjects since each technical committee has representation from all

23 interested IEC National Committees.

24 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

25 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

26 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

27 misinterpretation by any end user.

28 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

29 transparently to the maximum extent possible in their national and regional publications. Any divergence

30 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

31 the latter.

32 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

33 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

34 services carried out by independent certification bodies.

35 6) All users should ensure that they have the latest edition of this publication.

36 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

37 members of its technical committees and IEC National Committees for any personal injury, property damage or

38 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

39 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

40 Publications.

41 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

42 indispensable for the correct application of this publication.

43 9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

44 rights. IEC shall not be held responsible for identifying any or all such patent rights.

45 Amendment 1 to IEC 61918:2018 has been prepared by subcommittee 65C: Industrial

46 networks, of IEC technical committee 65: Industrial-process measurement, control and

47 automation.
48 The text of this Amendment is based on the following documents:

68 INTRODUCTION to Amendment 1

69 This Amendment 1 describes the installation in the critical environment of industrial premises

70 of balanced 1-pair networks that use cabling 1000BASE-T1 type A, which allows bidirectional

71 signal transmission at 1000 Mbit/s up to 15 m, 1000BASE-T1 type B for 1000 Mbit/s up to 40

72 m, 100BASE-T1 for 100 Mbit/s up to 15 m, 10BASE-T1S for 10 Mbit/s up to 15 m, 10BASE-

73 T1L for 10 Mbit/s up to 1000 m, where reach is influenced by cabling channel capacity

74 limitations from signal loss and electromagnetic interference.

75 These balanced 1-pair networks are the industrial versions of 1000 Mbit/s ISO/IEC/IEEE

76 8802-3:2017/AMD4, 100 Mbit/s ISO/IEC/IEEE 8802-3:2017/AMD1, and 10 Mbit/s IEEE

152 Add, before Figure 8, the following sentence:

153 The planner should consult the device and cabling manufacturer regarding correct selection of

154 the device and cabling for the environment of the installation under consideration (see B.6).

155 4.3.2.1 General
156 Add, at the end of the subclause, the following text:

157 Media types consist of optical fibre cabling, balanced cabling (4-pair, 2-pair, 1 pair), wireless,

158 and other CP specific media types. Wireless network installation is not within the scope of this

159 document. Selection of physical media technologies should partner with architectural

160 considerations, taking into account network topology, network characteristics, as well as data

161 propagation and aggregation throughout the network.

162 Optical fibre is generally recommended where high bandwidth is needed or a high data

163 integrity is required. Where powering is required or where reduced bandwidth or length

164 compared to optical fibre, wire cabling is recommended. 4-pair is mostly recommended for

165 connecting control and automation equipment. 1-pair (see Annex Q) is mostly limited to

166 connecting control and automation equipment with field devices.

167 The planner shall take into account the fact that unshielded cables need more distance from

168 power cable than any shielded cables. In practice more space means more costs because

169 bigger cable pathways or additional pathways dedicated to power or data cables are needed.

170 Worse, these additional requirements could be overlooked or ignored, which would generate

171 areas of high disturbance at critical points in the network.

172 Comparative measurements (unshielded versus shielded) confirm that shielded cables also

173 provide a much higher level of protection against EMI at high frequencies.

174 4.3.2.3 Network characteristics for balanced 1-pair networks based on Ethernet

181 different cable elements with varying pair count in the same channel (e.g., 2 and 4 pair or 1

182 and 4 pair),”
