Performance
SERCOS III has a substantial increase in transmission
speed, compared to the first two SERCOS implementations.
It uses proven hardware synchronization with a sub-microsecond
jitter, for precise real-time control. Some typical
values are:
| Size of Cyclic Data |
Cycle

No of Drives |
Type

number of drives in a ring |
This table shows the performance of drives on a single
ring. It's possible to combine multiple rings to create
a distributed network in order to increase the overall
performance of a system. Hundreds to thousands of
drives can be linked using peer-to-peer communications.
