At the recent Hannover Fair, the Sercos user organizations announced the development of a Safe Motion Profile for CIP Safety on Sercos. Safety of humans and machines is playing an increasingly vital role in the world of automation – machines and systems are becoming more complex while functional safety requirements are constantly on the rise.

Sercos relies on CIP Safety as the functional safety protocol for Sercos networks. To ensure the interoperability and compatibility of safety-related peripheral devices, such as controls, drives, and I/Os in cross-manufacturer systems, Sercos International and ODVA agreed to jointly develop a Safe Motion Profile based on CIP Safety.

The Safe Motion Profile guarantees that the safety-related functions of the peripheral devices are available across the entire network in a uniform and manufacturer-independent manner.
The profile includes the safety functions defined in IEC 61800-5-2, such as safe torque off, safe stop 1 and 2, and safely limited speed, mapping them to CIP Safety objects.

The specification of the Safe Motion Profile will be developed in close coordination with manufacturers and users and is planned to be available by April 2013.
