10 AMENDMENT 1
12 FOREWORD
13 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
14 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
15 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
16 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
17 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
18 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
19 in the subject dealt with may participate in this preparatory work. International, governmental and non-
20 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
21 with the International Organization for Standardization (ISO) in accordance with conditions determined by
22 agreement between the two organizations.
23 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
24 consensus of opinion on the relevant subjects since each technical committee has representation from all
25 interested IEC National Committees.
26 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
27 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
28 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
29 misinterpretation by any end user.
30 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
31 transparently to the maximum extent possible in their national and regional publications. Any divergence
32 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
33 the latter.
34 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
35 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
36 services carried out by independent certification bodies.
37 6) All users should ensure that they have the latest edition of this publication.
38 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
39 members of its technical committees and IEC National Committees for any personal injury, property damage or
40 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
41 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
42 Publications.
43 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
44 indispensable for the correct application of this publication.
45 9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
46 rights. IEC shall not be held responsible for identifying any or all such patent rights.
47 Amendment 1 to IEC 61784-5-2:2018 has been prepared by subcommittee 65C: Industrial
48 networks, of IEC technical committee 65: Industrial-process measurement, control and
49 automation.
50 The text of this Amendment is based on the following documents:

112 Replace “ANSI/TIA-568-C.1” with “ANSI/TIA-568.2-D” (no change to title).
113 B.4.2.2 Security
114 Replace the last paragraph with the following new paragraph:
115 CP 2/2 has provisions for supporting secure system designs aligned with IEC 62443.
116 IEC 62443 breaks down the design of security within a system to security levels based on risk
117 level. For each level there are different measures such as identification and authentication,
118 data access control, tamper detection, data access restriction, data confidentiality, response
119 time, and resource availability. Aspects of the system may need mitigations depending on the
120 level of security risk identified.
121 NOTE See [45] for more information on securing the installation of CP 2/2 systems. See ANSI/TIA 5017 [46] for
122 more information for deterrence or restricted access measures that may be taken for securing the physical
123 infrastructure of zones where it is deemed necessary or appropriate.
124 B.4.3.1.4 Combination of basic topologies
125 Replace “Not applicable” with the following new text and figure:
126 Replacement:
127 Through IEEE 802.1 bridging, CP 2/2 provides for routing of data through active topologies
128 and allows interfacing of all equipment through a hierarchical star topology. This is typically
129 facilitated through a network zone approach where an individual node on a network can be
130 replaced with an entire subnetwork configured in an independent topology such as a ring,
131 active linear bus, redundant active linear bus, or an additional active star. This concept is
132 shown in Figure B.18.
