Use case 1: unidirectional communication and OA on the SafetyConsumer side – OPC Unified Architecture

B.3.2 Use case 1: unidirectional communication and OA on the SafetyConsumer side

Figure B.4 – OA in unidirectional safety communication

In the scenario shown in Figure B.4, operator acknowledgment is done on the SafetyConsumer side, operator acknowledgment on the SafetyProvider side is not possible.
