Implementation of C# Program in Manufacturing Execution System Using Programmable Logic Controller for Education of Smart Factory

In this study, C# codes were implemented in a manufacturing execution system using a programmable logic controller for education of a smart factory. In the existing environment of an aviation campus, when MES education for a smart factory was conducted, HMI or SCADA programs were used as PLC-only software, and the trainees were limited to PLC specialized skills; therefore, MES specialists were nurtured. However, when implementing an OPC server and MS-SQL in PLC equipment by strengthening a smart factory system environment, notably, the control/monitoring function of an MES could be implemented using C# programs without using HMI or SCADA programs as PLC dedicated SW. It is expected that it will be of great help in finding employment by nurturing the MES manpower required in the industrial field, not limited to PLC specialized skills, as it provides trainees with a basic and functional understanding of the MES and C# program education.
