Overview
Ethernet Powerlink expands Ethernet with a mixed polling and timeslicing mechanism. This:
- Guaranteed transfer of time-critical data in very short isochronic cycles with configurable response time
- Time-synchronisation of all nodes in the network with very high precision of sub-microseconds
- Transmission of less timecritical data in a reserved asynchronous channel
Modern implementations reach cycle-times of under 200 µs and a time-precision (jitter) of less than 1 µs.
