Technological advancements in industry have paved way for the fourth industrial revolution called Industry 4.0. One critical aspect of this revolution is the usage of digital twins in product design, production, and service. A common depiction of a digital twin consists of three parts: a physical twin, its digital twin, and the data exchanged between them. In industry, one common solution for the data exchange between the digital twin and its physical twin is OPC Unified Architecture (OPC UA) communication protocol. The protocol provides a solution to collect data from devices along an entire production line. Communication with OPC UA servers requires carefully studying the protocol specification, which can deter new developers from creatin...
