December 28, 2007 - Santa Rosa Beach, FL - The S/IP (SERCOS/Internet Protocol) specification has been released by SERCOS International. The protocol allows standard Ethernet IP communication with a SERCOS III network both during cyclic real-time network operation and during non-real time operation. During real-time operation, the S/IP telegrams are transmitted via a non-real-time channel, without any negative effect on the real-time network behaviour. Unlike some competitive Ethernet motion networks, a SERCOS master need not be operational for IP communication to function. With the new S/IP protocol, the vertical integration of devices into a production system is improved. Any Ethernet device, such as a notebook computer, can be plugged into any unused SERCOS III port for upload/download of parameters and status information for set-up, reporting and remote maintenance and diagnostics over an intranet or the Internet. In addition to reading and writing the parameters of a device, S/IP supports the possibility of combining several tasks and sending them to the final device for processing. Manufacturer-specific services can also be added to the fixed, preset, standardized protocol services, which makes SERCOS III particularly flexible for users and developers. About SERCOS SErial Realtime COmmunications System (SERCOS) is among the leading digital interfaces for communications between controls, intelligent drives and decentralized peripheral devices, such as sensors and I/O. SERCOS has been used in modern production machines for over 20 years, with over 2 million real-time nodes implemented. With its open manufacturer-independent Ethernet-based architecture, SERCOS III is a universal bus for all automation solutions.
