SERCOS Bus

General

SERCOS (SErial Real time COmmunication System) interface is a worldwide standardized digital interface  for the communication between controls and drives (IEC 61491 and EN 61491).

As a transmission medium for sercos^® I and II a Fibre Optic ring is used. sercos^® III communicates on the physical medium of Ethernet, but later a Fibre Optic variant will be developed.

Features

• collision free transmission with the help of a time slot procedure
• very efficient communications protocol
• regulation of for example 40 axes with a cycle time from 1 ms and a jitter smaller than 1 µs.

sercos^® interface is supported by sercos^® International e.V. (SI).
