The emerging concept of Digital Transformation refers to the potential fourth industrial revolution. It took place within the Industrie 4.0 project through an economic development strategy proposed by the German government in 2011. Since then, the topic has been a matter of discussion in universities and large companies around the globe, becoming the center of business strategies to maintain competitiveness in the market. Cyber-physical systems are the backbone of the application of Industry 4.0, enabling collaborative, efficient, and sustainable production and integrating what were previously grouped by "functional silos". This happens due to its potential for integration between different technologies, enabling innovation in many domains, whether technological or economic sectors. Also, it represents process control for smart factories through cyber-physical integration and the use of ontologies in the semantic layer. Therefore, communication architectures used in Industry 4.0 that is currently evolving were revisited and an ontology was built for the integration of the semantic layer of information for a classical batch reactor control scheme. Orchestration and choreography architectures were designed to make it possible to offer control as a service to the process. For that, it starts with the control of an old batch reactor case of use, whose control application in the ladder diagram is from 1979, before the IEC 61512 and IEC 61131 standards. Also, the control structure was redesigned from the ontology for Industry 4.0, using OWL in its best-known form in Chemical Engineering, which is OntoCAPE. Thus, it demonstrates the ability of an ontology to generate control structures on the virtual side of CPS (Cyber-Physical System) with flexibility; and ready for interoperability, if necessary.
