Abstract
Today, Industrial Internet of Things (IIoT) devices are very often used to collect manufacturing process data. The integration of industrial data is increasingly being promoted by the Open Platform Communications United Architecture (OPC UA). However, available IIoT devices are limited by the features they provide; therefore, we decided to design an IIoT device taking advantage of the benefits arising from OPC UA. The design procedure was based on the creation of sequences of steps resulting in a workflow that was transformed into a finite state machine (FSM) model. The FSM model was transformed into an OPC UA object, which was implemented in the proposed IIoT. The OPC UA object makes it possible to monitor events and provide important information based on a client’s criteria. The result was the design and implementation of an IIoT device that provides improved monitoring and data acquisition, enabling improved control of the manufacturing process.
Highlights
The compatibility of the solution and integration of Industrial Internet of Things (IIoT) devices is suitably based on the properties of Open Platform Communications United Architecture (OPC unifiedarchitecture architecture (UA)) standards, which enable multilevel integration, monitoring of time-dependent data, and, where the historization of data generated during the production process is ensured [57,58]
The block not correspond to the protocols and ports that will be used in the final connection. In this diagram shows the structure of the proposed IIoT device. It consists of methods and events way, it is possible to replace some parts, and to create a functional prototype, which of OPC UA object, methods of application RESTful API client, methods of SPI API, and a can be used as a test solution that can reveal potential problematic parts of the design
The result of the notation is a format representing the to OPC UA, it is possible to provide an internal functionality of an IIoT device in the form application logic, and so it is possible to access both software and hardware of a state machine
Summary
IoT device integration is possibly based on the supported protocols. If the protocol is not supported, it is necessary to provide data transformation [12]. IoT devices do not provide event streaming data They are characterized by the fact that they generate large volumes of heterogeneous sensor data [26]. Such cases are handled by previous successful reads, and the process appears to have taken place without direct impact on the production line These features could be included in the design of the IIoT device, if necessary, if the solution used as a digital twin is taken in to consideration [30,31,32]. This model is oriented to provide more data, and it is able to generate or trigger events This is a major change in the understanding of an IoT device and its function in the production line. Such designthis of an supports bigare data, and the acquired be used is that in industry is IIoT well device known, and there technologies wheredata.
