The interconnection between sensors, controllers and instruments through a communication network plays a vital role in the performance and effectiveness of a control system. Since its inception in the 90s, the Object Linking and Embedding for Process Control (OPC) protocol has provided open connectivity for monitoring and automation systems. It has been widely used in several environments such as industrial facilities, building and energy automation, engineering education and many others. This paper presents a novel OPC-based architecture to implement automation systems devoted to R&D and educational activities. The proposal is a novel conceptual framework, structured into four functional layers where the diverse components are categorized aiming to foster the systematic design and implementation of automation systems involving OPC communication. Due to the benefits of OPC, the proposed architecture provides features like open connectivity, reliability, scalability, and flexibility. Furthermore, four successful experimental applications of such an architecture, developed at the University of Extremadura (UEX), are reported. These cases are a proof of concept of the ability of this architecture to support interoperability for different domains. Namely, the automation of energy systems like a smart microgrid and photobioreactor facilities, the implementation of a network-accessible industrial laboratory and the development of an educational hardware-in-the-loop platform are described. All cases include a Programmable Logic Controller (PLC) to automate and control the plant behavior, which exchanges operative data (measurements and signals) with a multiplicity of sensors, instruments and supervisory systems under the structure of the novel OPC architecture. Finally, the main conclusions and open research directions are highlighted.

Programmable logic controller (PLC) is always set as a professional course of automation-related majors in Chinese universities and colleges. Abundant experiments are required to ensure that the students are sufficiently trained to get qualified practical skills and engineering abilities. The evaluation of abundant PLC experiments is a heavy and time-consuming task, and it is hard to grade an experiment result precisely and fairly. In this paper, a cloud-based automatic evaluation system for PLC experiments is accordingly proposed to deal with the above problems. Aliyun is employed to build the system platform. During experiments, client threads on the cloud will be scheduled to accesses the on-site S7-1500 PLCs through OLE for process control (OPC) UA protocol. Further, an innovative sectionbased experiment management method is proposed to make the system open, configurable, and thus extendable. The system relieves the hard work of the teachers on experiment evaluation and provides accurate evaluation conclusions. In contrast, the students can get more comprehensive feedback information and advice from the system to better understand the experiments and the behind principles. The cloud-based framework, the standard protocol as OPC UA, and the configurability of the system can be good references for other relevant systems.

“…Many technological developments, and especially the rapid growth of the internet, provide great opportunities in the fields of education and research. 1,2 The Internet, providing a supportive learning environment and the spreading of information to broad masses without typical time and space constraints in distance education, also leads to improvements in engineering education which includes laboratory experiments. [2][3][4][5] Since outdated tools and instruments are generally used in laboratories of engineering departments in universities due to budgetary constraints, 2 virtual, web-based and remotely accessible laboratories are integrated with science and technology education to provide more opportunities for individuals to learn or collaborative learning of groups.…”

Thanks to the development of education and internet technologies, two-dimensional educational environments such as internet pages in distance education are starting to leave their places to three-dimensional virtual worlds with more communication and interaction tools, that offer with–without instructor, synchronous–asynchronous and individual–collaborative learning environments. In this study, a new basic programmable logic controllers laboratory was designed, simulated and virtually implemented on Second Life, a 3D virtual world with powerful features such as object construction and programming language. Then, this virtual programmable logic controllers laboratory was introduced to the students of Electricity and Energy Department of Usak University who had previously taken the programmable logic controllers course theoretically, and a survey about this laboratory was administered. One-hundred percent of the students who participated in the survey found this lab to be helpful, and 95.45% found it to be useful. Based on this lab design and evaluations, the specific and general conclusions including the pros and cons are discussed.
