IEC PAS 62953:2015

Industrial communication networks - Fieldbus specifications - ADS-net

IEC PAS 62953:2015(E) provides common elements for basic time-critical messaging communications between devices in an automation environment. It defines the services provided to the Type 25 fieldbus: application layer at the boundary between the application and datalink layers of the fieldbus reference model; systems management at the boundary between the data-link layer and systems management of the fieldbus reference model.

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 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 62953 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/787/PAS 65C/799/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 period up to a maximum of
3 years, at the end of which it shall be published as another type of normative document, or
shall be withdrawn.

INTRODUCTION
This PAS contains the ADS-net fieldbus specifications and profiles (Communication profile CP

20/1 ADS-net/μΣNETWORK-1000, CP 20/2 ADS-net/NX) for inclusion in the IEC 61158 series

as well as IEC 61784-2.
The intention is to make this technical content available immediately, while a corresponding
new work item proposal (NP) has been launched. If the NP is accepted, this contents will be

included in the next editions of the IEC 61158 series and of IEC 61784-2.

This PAS contains the relevant ADS-net (Type 25) elements for the DL and AL services and

protocols and information with references to:

– IEC 61158-1:2014
– IEC 61158-2:2014
– IEC 61784-2:2014
The present IEC PAS is structured in the same way as the IEC 61158 series and IEC
61784-2:
– IEC PAS 62953-3-25 is intended to become a future IEC 61158-3-25;
– IEC PAS 62953-4-25 is intended to become a future IEC 61158-4-25;
– IEC PAS 62953-5-25 is intended to become a future IEC 61158-5-25;
– IEC PAS 62953-6-25 is intended to become a future IEC 61158-6-25;
– IEC PAS 62953-2 is intended to be merged into a revised version of IEC 61784-2:2014.
