Foreword
This European Standard was prepared by the Technical Committee CENELEC TC65CX, Fieldbus.
EN 50170/A3 (ControlNet) is a serial communication system for communication between devices that wish to
exchange time critical application information in a deterministic and predictable manner. These devices include
simple I/O devices, such as sensors/actuators as well as complex control devices such as robots, programmable
logic controllers, welders, process controllers, etc.
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as
amendment A3 to EN 50170:1996 on 2000-08-01.
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) 2002-11-01
- latest date by the national standards conflicting with
the EN have to be withdrawn (dow) 2003-08-01
