The frequent absence of well described assets and the poorly structured and non-available live data is considered as one of the main roadblocks towards this future. This paper addresses the issues by creating an ontology for MTConnect standard. MTConnect provides the basis to describe machines , their device structure including sensors and their measurement values. The ontology is tested using live data and we further provided multiple queries to execute certain machine health tests.enindustry 4.0MTConnect standardindustrial control systemOntologysemantic technology005006629conference paper
