May 1, 2012 - Sercos International (SI) announces the development of a Safe Motion Profile for CIP Safety. Sercos International 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 way.
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 takes place in close coordination with manufacturers and users and is planned to be available by April 2013.
About CIP Safety
CIP Safety is a network protocol for functional safety. It has been certified by TÜV Rheinland for use in applications up to Safety Integrity Level 3 (SIL3) and complies with IEC standard 61508 for functional safety (“Functional safety of electrical/electronic/programmable electronic safety-related systems”). The functions of the media-independent CIP Safety protocol are performed by the end units, allowing standard and safety devices to operate in the same network. This makes it possible for users to flexibly configure the safety network architecture for implementation of safety programmable controllers or peer-to-peer transmission of data between sensors and actuators.
In addition, use of a standard CIP network as a backbone network enables seamless communication between safety devices in different sub-networks.
About Sercos
The SErial Realtime COmmunication System, or sercos, is one of the world’s leading digital interfaces for communication between controls, drives, and decentral peripheral devices. Sercos has been used in machine engineering for more than 20 years and is implemented in over 3 million real time nodes. With its open, manufacturer-independent architecture on an Ethernet base, sercos III offers a universal bus for all automation solutions.
