SERCOS International Announces Adoption of CIP Safety™
on SERCOS
SERCOS International (SI) and ODVA announced today that SI will adopt CIP Safety™
as its functional safety protocol for SERCOS. ODVA, for its part, will extend The CIP Safety
Specification to include safety profiles for SERCOS devices. SI, for its part,
will develop the SERCOS network adaptation to utilize CIP Safety. SI and ODVA,
jointly, will develop and establish conformance testing for devices implementing CIP Safety
on SERCOS to help ensure compliance with the collective body of specifications and enable interoperability of these devices
in multi-vendor systems.
This action is consistent with the desires of industry to have a single, worldwide network
protocol for safety applications. Further, the joint support of CIP Safety
by ODVA and SI will facilitate technical and market synergies for users and vendors of functional safety networks.
"SERCOS interface is the world-leading digital drive interface
with more than 20 years history and worldwide acceptance in all servo-driven motion applications," states Peter Lutz, managing
director of SERCOS International. "Using CIP Safety as the functional safety protocol on SERCOS III, SI's new generation industrial Ethernet network, opens up completely
new possibilities and leads to a greater versatility for applications with safety requirements.
This provides significant benefits not only to the SERCOS users and vendors but for the worldwide safety
community."
"CIP Safety stands alone as the world's only media-independent,
truly open network protocol for functional safety," states Katherine Voss, executive
director of ODVA. "Adoption of CIP Safety by SERCOS International will provide
users of SERCOS technology with a functional safety solution that meets industry's
growing requirement for seamless integration of safety networks with the overall
network architecture."
The responsible technical working group within SI has already started to extend and adapt
its initial "SERCOS safety" concept -- published and approved by TÜV Rheinland
in November 2005 -- to CIP Safety. SI and ODVA expect that the enhancements to
their respective specifications to encompass the adaptation of SERCOS to CIP Safety
will be published during 2007. They also expect that first device implementations will be released by the end of 2007.

About CIP Safety
CIP Safety is a network protocol for functional safety. It has been certified by TÜV Rheinland
to comply with the IEC standard for functional safety 61508 entitled "Functional safety of electrical/electronic/programmable
electronic safety-related systems," for use in applications up to Safety Integrity Level 3 (SIL3). The CIP Safety protocol
is media-independent and its functionality resides in the end nodes, allowing both standard and safety devices to operate
on the same network. It provides the user with flexibility in design of safety network architecture to utilize safety programmable
controllers or peer to peer communication between sensors and actuators. It also allows safety devices on one subnet to communicate
seamlessly to safety devices on another subnet using a standard CIP Network as a backbone.
About SERCOS III
SERCOS
III is based on the established real time mechanisms of the original SERCOS interface, still using the principle of cyclic
data transfer with deterministic timing. This hardware-based synchronization is the indispensable prerequisite for the reliable
implementation of challenging motion applications, such as packaging machines, multi-axis machine tools and electronic line
shafts in printing machines. SERCOS III has been defined such that any standard Ethernet frame (e.g., TCP/IP) can be transmitted
in a non-real time slot, in parallel to the real time processing. A SERCOS III control system is able to exchange these telegrams
with super-ordinate devices in the network. Thus, SERCOS III combines the established SERCOS real time mechanisms and standardized
parameter set with universal communications based on Industrial Ethernet.
About SERCOS International
SERCOS
International (SI) is the responsible user organization for the technical development, standardization, certification and
commercialization of the real time communication standard SERCOS interface (IEC 61491). At present, more than 1.75 million
SERCOS nodes have been implemented world-wide in over 350 thousand applications. SI offers conformance testing to help ensure
that products built to its specifications operate in multi-vendor systems. The organization with its headquarters in Germany
has presently more than 60 member companies all over the world as well as own trade associations in North America and Asia.
About
ODVA
ODVA is an international association comprised of members from the world's leading automation companies. Collectively,
ODVA and its members support network technologies based on the Common Industrial Protocol (CIP™). These currently include
the network adaptations of CIP -- DeviceNet™, EtherNet/IP™, and CompoNet™ -- along with major extensions
to CIP -- CIP Safety™, CIP Sync™ and CIP Motion™. ODVA manages the development of these open technologies,
and assists manufacturers and users of CIP technologies through tools, training and promotional activities. In addition, ODVA
offers conformance testing to help ensure that products built to its specifications operate in multi-vendor systems. ODVA
also is active in other standards development organizations and industry consortia to drive the growth of open communication
standards. For more information, visit the ODVA web site.
