Nuremberg, Germany — November 26, 2013 — The next edition of The CIP Safety Specification will include services for safe motion applications. With the addition of these services to CIP Safety, users will be able to deploy networked motion control systems using EtherNet/IP and Sercos® III in applications requiring safe motion functions such as safe torque off and safety limited positions. 

First released in 2005 by ODVA to solve functional safety applications using devices such as safety gates and light curtains, CIP Safety™ has established itself as a key network technology in achieving the sustainability objectives of industry. In 2006, Sercos International announced that it would adopt CIP Safety as its safety protocol for Sercos. Since that time, ODVA and Sercos International have worked together on enhancements to The CIP Safety Specification and its associated conformance tests, as well as on broader industry topics such as machine integration. 

As it relates to safe motion, the recent enhancements to CIP Safety relied on IEC 61800-5-2 (Adjustable Speed Electrical Power Drive System – Part 5-2: Safety Requirements – Functional) as a framework. Initiated by ODVA and Sercos International as part of the machinery initiative, the enhancements were further developed by ODVA’s technical working group for functional safety, the Special Interest Group (SIG) for CIP Safety. The interest group is a collaboration of multiple vendors with expertise in functional safety and safe motion, including Bosch Rexroth, Rockwell Automation and Schneider Electric among others – involving technical expertise from Sercos International. The resulting CIP Safety services for safe motion include support for drives on EtherNet/IP and Sercos III. The safe motion enhancements to CIP Safety are part of ODVA’s semi-annual update of its family of specifications which, for the second publication cycle of 2013, include over 20 different enhancements.

ODVA’s offer of conformance tests for CIP Safety now extends to devices for Sercos III, EtherNet/IP and DeviceNet. Devices which succeed in meeting the requirements for ODVA’s CIP Safety conformance test and are certified by an authorized competent body for full compliance with IEC 61508 will receive a Declaration of Conformity from ODVA indicating compliance with The CIP Safety Specification. Bosch Rexroth is the first company with a device holding ODVA’s Declaration of Conformity for CIP Safety on Sercos III. These tests are currently available at ODVA’s Test Service Provider (TSP) in North America. 

“CIP Safety provides users with a proven approach to functional safety that is supported by multiple vendors and two leading consortia, ODVA and Sercos International,” stated Katherine Voss, president and executive director of ODVA. “The extension of safe motion to CIP Safety will further accelerate adoption and innovation in motion control systems using EtherNet/IP and Sercos III.” 

“The inclusion of safe motion in CIP Safety will provide machine builders with an integrated and flexible solution for functional safety,” added Peter Lutz, managing director of Sercos International. “Moreover, the availability of CIP Safety conformance testing for Sercos III will facilitate the implementation and certification of CIP Safety on Sercos III devices, and help to ensure that machine builders are able to deploy certified functional safety devices in machines using Sercos.”

Vendors seeking to prepare for the CIP Safety conformance test will also be able to purchase the ODVA Conformance Test Software for CIP Safety. This software is the same used by ODVA’s TSPs to determine compliance with The CIP Safety Specification. Enhancements to the conformance test software will be on-going, including, but not limited to, coverage for safe motion. Vendors who hold subscriptions to the conformance test software will receive software updates as they become available.

In addition to their collaboration on CIP Safety, in 2014 ODVA and Sercos International will continue their related collaboration with the OPC Foundation on machinery integration, which is currently focused on machine-to-supervisory communication and logical groupings of data such as functional safety. ODVA also expects to expand its CIP Safety conformance testing for EtherNet/IP and Sercos III to TSPs in Germany.

About ODVA
Founded in 1995, ODVA is a global association whose members are comprised of the world’s leading automation companies. ODVA’s mission is to advance open, interoperable information and communication technologies in industrial automation. ODVA recognizes its media independent network protocol, the Common Industrial Protocol or “CIP” — and the network adaptations of CIP — EtherNet/IP, DeviceNet, CompoNet and ControlNet — as its core technology and the primary common interest of its membership. For future interoperability of production systems and the integration of the production systems with other systems, ODVA embraces the adoption of commercial-off-the-shelf (COTS) and standard, unmodified Internet and Ethernet technologies as a guiding principle wherever possible. This principle is exemplified by EtherNet/IP — the world’s number one industrial Ethernet network.
