Raspberry Pi based SCADA system using Codesys for workshop facilities

Abstract This study aims to create a prototype of the SCADA system used control lighting source facilities and fan-based Raspberry Pi in workshop Electrical Engineering Study Program Politeknik Enjinering Indorama. consists Model B, UL 2803 Driver, switch module, relay lamp, fan. as controller or mini PLC programmed using CodeSys software with ladder logic diagram programming. The System process can also be done through HMI display (Human Machine Interface), is designed Codesys Web Visualization feature so controlled PC mobile web browser while connected campus intranet network. results showed that was built able sources for fans both locally remotely real-time an average time 200 ms.
