Safety over EtherCAT Specification

In the interest of realizing safe data communication over EtherCAT, the Safety over EtherCAT protocol (Fail Safe over EtherCAT, FSoE) has been disclosed within the EtherCAT Technology Group. EtherCAT is used as a single-channel communication system for transferring safe and non-safe information. The transport medium is regarded as a "black channel" and not included in safety considerations. A safety frame containing the safe process data and the required data backup is included in the EtherCAT process data. This "container" is safely analyzed in the devices at the application level. Communication remains single-channel. This corresponds to Model A from the Annex of pre-IEC 61784-3.

The Safety over EtherCAT protocol has been assessed by German Technical Inspection Agency (TÜV). It is certified as a protocol for transferring process data between Safety over EtherCAT devices up to SIL 3 according to IEC 61508. The implementation of the Safety over EtherCAT protocol in a device must meet the requirements of the safety target. The associated product-specific requirements must be taken into account.
