Information model for the digital transformation of manufacturing systems in small and medium enterprises

This article proposes the development of an information model that allows starting the digital transformation of a small or medium-sized company (SME) using the OPC UA protocol. The model is made up of a hardware component made up of the process plant and the control equipment, as well as a software component where the information model is implemented.As an application case, the proposed information model is developed in a unit process plant, a filtration plant. The process carried out in this plant is through a filter to remove the solid particles present in the water used in the manufacturing process of a beverage. This plant can be integrated into a beverage and/or soft drink manufacturing system in a small company.The information model is integrated into an OPC UA server, a programmable controller, mapping the process variables such as level, temperature flow, and energy consumption. The information of the technological elements that make up the filtration plant are: serial, manufacturer, and calibration dates: OPC UA clients request information from the OPC UA server and then they are sent through procedures (methods) defined in the server and consumed by the server. client, all this integrates the information model.The foregoing shows the viability of the proposed
