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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 62633 has been processed by subcommittee 65C: Industrial networks, of IEC
technical committee 65: Industrial-process measurement, control and automation.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
65C/530/PAS 65C/534/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

communication profiles
7.1 General overview
Communication Profile Family SNpFAMILY defines profiles based on IEC/PAS 61158-3-22
through IEC/PAS 61158-6-22.
In this part of IEC 61784, the following communication profiles are specified for CPF
SNpFAMILY.
• Profile SNpFAMILY/1
This profile defines protocol and service selection for devices which utilize the
communication model real time frame line (RTFL).
• Profile SNpFAMILY/2
This profile defines protocol and service selection for devices which utilize the
communication model real time frame network (RTFN).
7.2 Profile SNpFAMILY/1
7.2.1 Physical layer
The physical layer shall be based on standard Ethernet hardware according to
ISO/IEC 8802-3.
CP SNpFAMILY/1 devices shall use a data rate of 100 Mbit/s and full-duplex transmission
mode. A combination of full-duplex and 100Base-TX with auto crossover function (wire, 2
twisted pairs) should be used.
When using cables, they shall be rated Cat5e or better, and shielded in an appropriate way
(FTP, STP or SFTP) depending upon EMC constraints.
7.2.2 Data link layer
Data link layer is described in IEC/PAS 61158-3-22 and IEC/PAS 61158-4-22. Table 1
specifies the use of the services included in this profile. Table 2 specifies the use of the
protocol included in this profile.
