SERCOS III – universal communication for all applications
The vision of a real-time, non-proprietary communication solution permeates the world of industrial automation.
Different types of automation devices have to be network-enabled in an easy and consistent way.
SERCOS III, the open, IEC-compliant universal bus for Ethernet-based real-time communication, already delivers the functionality you need.
What is new?
- Industrial Ethernet is used as the physical layer and protocol
- Faster due to higher bandwidth and shorter cycle times
- More precise due to an innovative synchronization procedure
- More universal due to new communication and device profiles
- New, innovative communication functions, e.g. direct cross communication and hot-plugging
- Higher machine availability due to communication redundancy
What has been retained?
- Proven features such as topology, profiles, message structures and synchronization have been retained
- Existing drivers and applications can be simply transferred to SERCOS III
