Staff -- Control Engineering, 1/1/2008
The International Electrotechnical Commission (IEC) unanimously approved SERCOS III, the real-time Ethernet version of the SErial Realtime COmmunication System (SERCOS) interface, as part of international standard IEC 61784-2 (Digital data communications in control technology) and IEC 61158 (Field bus for industrial control systems), according to organizations involved. SERCOS III is the third generation of the SERCOS interface, and integrates the open Ethernet protocol with high-speed data transfer at 100 MBit per second, according to information provided by SERCOS North America and Germany-based SERCOS International e.V. Additional innovations include improved safety, the construction of efficient networks with minimum cabling due to a redundant ring and/or line structure, and specific cross communication traffic between control systems.
