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

77 802.3cg networks.

146 Add, after the first sentence of the third paragraph, the following text:

147 The industrial cabling may include an edge distributor to accommodate active equipment to

148 allow transition from balanced 4-pair cabling to balanced 1-pair cabling.
149 4.1.3 The planning process
150 Replace, in the first bullet, “IEC 60950-1” with “IEC 61010-2-203”.
151 4.2.3.2 Use of the described environment to produce a bill of material
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

175 Add, at the end of the subclause, the following text:
176 For balanced 1-pair networks the requirements specified in Annex Q apply.
177 4.4.1.2.1 Balanced cables for Ethernet-based CPs
178 Add, after the first sentence, the following text:
179 For balanced 1-pair cables the requirements specified in Annex Q apply.

180 Replace, in the fourth bullet, “cabling that uses mixed 2 and 4 pair” with “cabling that uses

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

182 and 4 pair),”

188 Add, at the end of the first sentence of paragraph 5, the following text:
189 for 4-pair cabling. For 1-pair cabling see Annex Q.

190 Replace, at the end of the second sentence of paragraph 5, “are limited to 4. If the planning

191 requires more than 4 connections,” with “have a limited number of connections (e.g., 4 for 4

192 pair and 10 for 1 pair). If the planning requires more connections than the corresponding

193 reference implementation”
194 4.4.3.2.1 Common description
195 Change title of bullet a) to: “a) 4-pair basic reference implementation”
196 Change title of bullet b) to: “b) 4-pair enhanced reference implementation”

198 d) Balanced 1-pair cabling

199 For balanced 1-pair cabling connections the requirements specified in Annex Q apply.

200 4.4.7.1.4 Selection of the earthing and bonding systems

202 4.4.7.3.1 Equipotential
203 Replace the title of the subclause with “Mesh”.
204 Replace, in the title of Figure 17, “equipotential” with “mesh”.
205 5 Installation implementation
206 5.1.1 Common description
207 Add, at the end of the subclause, the following text:

208 The requirements specified in this Clause 5 for the CPs also apply for the installation

209 implementation of balanced 1-pair networks specified in Annex Q.

210 If additional requirements are needed, they will be added in Annex Q and here the

211 following text will be added to the above sentence.
212 Additional requirements are specified in clause Q.3.
