sercos III - the automation bus
Various field devices (drives, I/Os, controls,...) can communicate over the same standardized real-time communication interface.
sercos III is powerful
Cycle times between 31,25 µs and 65 ms
Synchronization accuracy < 20 ns
Simultaneity < 100 ns
Slaves can directly exchange real-time data among each other within one communication cycle.
sercos III is universal
Any Ethernet protocol (TCP/IP, UDP/IP, ...) can run simultaneously to the real-time data transmission - tunneling is not necessary.
sercos III is safe
Safety functions up to SIL3 over „CIP Safety on sercos“.
sercos III is highly available
Thanks to the ring redundancy feature communication can continue free of distortion even at cable break. The re-configuration time is less than 25 µs.
sercos III is flexible
central or decentral - ring or line - hot-plugging and hot-swapping - hierarchical, synchronous network structures
sercos III is simple
Standardized communication and device profiles, exact diagnosis down to IO channel level, simple cabling by exchangeability of the two ports.
sercos III is cost-effective
No infrastructure costs for hubs, switches etc. - cost-effective implementation based on flexible FPGA technology.
sercos III is an international standard
IEC 61158 - IEC 61784 - IEC 61800-7
sercos III is proven
More than 2 million SERCOS devices in over 400.000 applications world-wide.
