OPC-10000-15 – OPC Unified Architecture - Part 15: Safety1 ScopeScope This document describes a safety communication layer (services and a protocol) for the exchange of SafetyData using OPC UA mechanisms. It identifies the principles for functional safety communications defined ... that are relevant for this safety communication layer . This safety communication layer is intended for implementation in safety devices only. NOTE 1 This document targets controller-to-controller communication. However

OPC-10000-81 – OPC Unified Architecture - Part 81: UAFX Connecting Devices and Information ModelUsage of OPC UA safety Variables in Connections OPC UA Safety provides an application protocol using safety Variables , which is implemented by the SafetyProvider / SafetyConsumer . The communication layer is completely ... unaware that safety data is being transported. Any logical connection could reference any number of safety and non-safety Variables , even from different SafetyProviders or SafetyConsumers . There is nothing special
