Sercos
Sercos, short for Serial Real-Time Communication System, is a family of open, vendor-neutral standards for real-time communication in automation and motion control. It enables controllers, servo drives, and I/O devices to exchange cyclic process data with deterministic timing, supporting synchronized operation across complex production lines.
Developed in the 1990s by a consortium of European automation providers led by Siemens and Robert Bosch,
Key features include cyclic data transfer of process data, non-cyclic service data, time synchronization with a
Historically dominant in CNC machines, machine tools, robotics, and other automated equipment in Europe, SERCOS is
