SERCOS interface

In the field of Industrial Control Systems, the interfacing of various control components must provide means to coordinate the signals and commands sent between control modules. While tight coordination is desirable for discrete inputs and outputs, it is especially important in motion controls, where directing the movement of individual axes of motion must be precisely coordinated so that the motion of the entire system follows a desired path. Types of equipment requiring such coordination include metal cutting machine tools, metal forming equipment, assembly machinery, packaging machinery, robotics, printing machinery and material handling equipment. The Sercos (serial real-time communication system) interface is a globally standardized open digital interface for the communication between industrial controls, motion devices (drives) and input output devices (I/O). Sercos I and II are standardized in IEC 61491 and EN 61491. Sercos III is specified in standards IEC 61800-7; IEC 61784-1, -2, -3 and IEC 61158. Sercos is designed to provide hard real-time, high performance communications between industrial motion controls and digital servo drives.

Sercos International e.V. supports a Conformance Laboratory at the University of Stuttgart's Institute for Control Engineering of Machine Tools and Manufacturing Units (ISW). Products successfully passing conformance testing may display a mark indicating they are conformance tested. Conformance-tested Sercos I and II products are publicized in an index of certified products, Sercos I and II. Conformance-tested Sercos III products are publicized in an index of certified products, Sercos III. ==References==
