OPC 10000-15: UA Part 15: Safety

This specification has its origin in a joint working group between the OPC Foundation and the Profibus Nutzerorganisation e.V. (PNO) which was established in November 2017. The experts of this joint working group initially elaborated a safety concept for controller-to-controller communication using the black channel approach according to IEC 61784-3 "Functional safety fieldbuses" based on the OPC UA Client/Server communication model. The launch of the Field Level Communication Initiative in November 2018 has resulted in an extension of the safety concept to also support controller-to-device communication and the Pub/Sub communication including transport via Ethernet and Ethernet TSN.
