Industrial communication protocols are important for interconnecting systems and machines in industrial environments. In this study, we evaluated the performance and complexity of OPC-UA, Modbus, and Ethernet/IP protocols when used with machine tools. Our results show that Modbus has the best latency figures, and the complexity of communication varies depending on the protocol used.
Industrial communication protocols are protocols used to interconnect systems, interfaces, and machines in industrial environments. With the advent of hyper-connected factories, the role of these protocols is gaining relevance, as they enable the real-time acquisition of machine monitoring data, which can fuel real-time data analysis platforms that conduct tasks such as predictive maintenance. However, the effectiveness of these protocols is largely unknown and there is a lack of empirical evaluation which compares their performance. In this work, we evaluate OPC-UA, Modbus, and Ethernet/IP with three machine tools to assess their performance and their complexity of use from a software perspective. Our results show that Modbus provides the best latency figures and communication has different complexities depending on the used protocol, from the software perspective.
