(2021) The productivity impact of the digitally connected 5 - layer stack in manufacturing enterprises. Procedia CIRP, Volume 104, pp. 342-350. 54th CIRP Conference on Manufacturing Systems 2021 (CIRP CMS 2021), 22-24 September 2021, Virtual Event2212-8271https://doi.org/10.1016/j.procir.2021.11.058https://dspace.lib.cranfield.ac.uk/handle/1826/17304This paper investigates the application of modern industrial internet protocols and network architecture in manufacturing companies, from the perspectives of productivity and sustainability, framed in the fourth industrial revolution paradigm. This is achieved by delving into the existing information systems and devices, their inter-operability and interconnections using industrial internet of things protocols. The paper details a study generating a standard model of data architecture to better unify the different layers of the information systems that typify most manufacturing companies, leveraging their existing digital infrastructure to establish a solid base for further digitalization.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Industry 4.0Industrial Internet of Things (IIoT)MQTTManufacturing Execution System (MES)SCADAEnterprise Scalable Data Architecture (ESDA)Overall Equipment Efficiency (OEE)Self-Cleaning-DataConference paper
