Evaluation of OPC UA technology in order to minimize systems unavailability by improving M2M connectivity

Eventually the industrial automation engineer is challenged to optimize a M2M communication process. For this, it is essential to observe the infrastructure offered by the company and the resources available in legacy equipment. Developing a simple, economically viable solution that makes use of open communication standards is highly recommended. Alternatives that do not require large investments gain a significant dimension; another important factor in this decision is that the chosen solution should be able to operate harmoniously with existing legacy systems. By doing so, the company will be in a position to gradually pursue the Industry 4.0 concept and to preserve the most investments already made. This paper aims to describe OPC UA technology, test it in a controlled environment in order to meet a real production demand and justify how and why its differentiated characteristics are recommended for Industry 4.0 applications. http://dx.doi.org/10.18226/23185279.v7iss2p40
