SEMANTIC CONTEXTUALIZATION IN A PROGRAMMABLE LOGIC CONTROLLER

摘要

A method of contextualizing automation system data in an intelligent programmable logic controller includes the intelligent programmable logic controller collecting automation system data and creating a structured representation of the automation system data. The intelligent programmable logic controller selects a semantic context model from a plurality of available semantic context models based on relevance to the structured representation of the automation system data and creates semantically contextualized data using the semantic context model and the structured representation of the automation system data. The semantically contextualized data is stored by the intelligent programmable logic controller on a non-volatile computer-readable storage medium operably coupled to the intelligent programmable logic controller.
