CIP Safety standard to include safe motion applications
The next edition of The CIP Safety Specification by ODVA 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.
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 enhancements.
