Safety over EtherCAT license

Safety over EtherCAT license

In the interest of realising safe data communication for EtherCAT, the Safety over EtherCAT protocol has been disclosed. The protocol meets the requirements of IEC 61508 up to Safety Integrity Level (SIL) 3 and of IEC 61784-3, as approved by the TÜV.

EtherCAT is used as a single-channel communication system. The transport medium is regarded as a “black channel” and not included in the safety considerations. Thus, the protocol can also be transmitted by other communication systems, backplanes, WLAN. The cyclic exchange of safe data between a Safety over EtherCAT master and a Safety over EtherCAT slave is referred to as a connection that is monitored via a watchdog timer.

The license for implementation of the Safety over EtherCAT master and slave technology in a device is free of charge.
