SERCOS is based on the first international standard for digital realtime communication in drive applications. It uses a standardized protocol and standardized communication and device
profiles. SERCOS III devices are fully compatible with each other without the need for special drivers or configuration files.

SERCOS III communication is based on standardized parameter
sets to control device functions. There are no hardware or manufacturer dependencies. When the network is initialized, the parameters which make up the realtime data set on the device channel are defined in the configuration.
SERCOS III is a universal bus which offers communication channels
and device profiles for all standard automation applications:
Real-time communication channel:
- M/S (master/slave): exchange of functional data between master and slave in an M/S data channel
- CC (cross communication): direct peer-to-peer communication
between devices on a CC device channel, either between
controllers (C2C) or between drives and peripheral slaves (CC)
- SVC (service-channel): service data exchange on an SVC channel
- SERCOS safety: exchange of safety-related data on an M/S or CC device channel, e.g. shut down or enable signals
NRT communication channel:
- standard Ethernet: connectivity to any non-real-time Ethernet device such as a notebook PC or I/O device
- other Ethernet protocols: routing of special Ethernet protocols on a NRT channel, e.g. third-party real-time protocols
Device profiles:
- motion profile: motion and PLC functions for controllers based on SERCOS motion control parameters with additional enhancements and better performance
- Drive profile: drive control functions
- I/O profile: functions to control I/O devices
Communication channels and device profiles can be combined for nearly all combinations of applications, e.g. for packaging profile (OMAC-standard for drives in packaging machines.
