Industrial communications subsystem based on ISO 11898 (CAN)
for controller-device interfaces
Part 3: Smart Distributed System (SDS)
This European Standard was approved by CENELEC on 2000-04-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this
European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists only in English. A version in any other language made by translation
under the responsibility of a CENELEC member into its own language and notified to the Central
Secretariat has the same status as the official version.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 65CX, Fieldbus.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 50325-3 on 2000-04-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2001-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2003-04-01
EN 50325 is divided into three parts:
Part 1 General requirements
Part 2 DeviceNet
Part 3 Smart Distributed System (SDS)
The specifications for DeviceNet and SDS are based on ISO 11898 Controller area network (CAN) for
high-speed communication, a broadcast-oriented communications protocol. However, ISO 11898 specifies
only part of a complete communication system, and additional specifications are needed for other layers to
ensure precise data exchange functionality and support of inter-operating devices. The DeviceNet and
SDS specifications build on ISO 11898 to describe a complete industrial communication system.
