Applying CoAP protocol in the Industrial Internet of Things (IIoT) is a very attractive scenarios. OPC Unified Architecture (OPC UA) defines a semantic-based information model and a service-oriented architecture for industrial control system that can satisfy the requirements of Industry 4.0, which is based on semantic information exchange.
