Resumen

The Fourth Industrial Revolution (also known as Industry 4.0) has the Industrial Internet of Things (IIoT) as one of its principal trends. It offers connectivity and access to information for industrial devices. However, the heterogeneity of communication protocols set by different vendors and the lack of TCP/IP readiness prevent several devices from implementing IIoT. The OPC UA standard can offer a solution due to its client-server communication model and its information architecture, which are-platform independent. By implementing it in industrial devices, the standard can bridge the gap between protocols and help achieve IIoT. The main potential benefits are monitoring and control for industrial processes and remote access to laboratories for education. The goal of the current work is to use OPC UA to connect a Programmable Logic Controller (PLC) and a Virtual Instrument (VI) running as a Web Services application. It uses a SCADA system as a case study; it consists of a bottle production line simulated in FluidSIM. S7-PLCSIM is used to simulate the PLC that controls the system, and LabVIEW to create a VI and export it as an application. NI OPC Servers software is then employed to run an OPC UA server and define the PLC as its client. The results show a successful connection and demonstrate that the OPC UA standard can be used for implementing IIoT by connecting a simulated PLC to a VI for bidirectional information exchange in monitoring and control tasks.

Keywords: Industrial Internet of Things (IIoT), OPC UA, Programmable Logic Controller (PLC), Virtual Instrument (VI).
