Constrained Application Protocol (CoAP) is an application protocol proposed for constrained nodes and constrained networks. Industrial Internet of Things (IIoT) is an attractive scenario for CoAP. OPC Unified Architecture (OPC UA) defines a semantic-based information model and a service-oriented architecture for IIoT, which can satisfy the requirements of Industry 4.0. This document analyses requirements for transmitting OPC UA over CoAP.
