Abstract

This study addresses the growing need for reliable and uninterrupted electrical power systems in educational automation laboratories, where power disturbances can disrupt experiments, damage sensitive equipment, and reduce operational efficiency. The research aims to design, implement, and evaluate a Supervisory Control and Data Acquisition (SCADA) system for monitoring power source transfer status in an Automatic Transfer Switch (ATS) at the Automation Laboratory of the Electrical Engineering Department, Politeknik Negeri Manado. The study employed an experimental and engineering-based research method involving system design, hardware integration, software programming, and performance testing. The system utilized a Siemens S7-1200 Programmable Logic Controller (PLC), Modbus TCP/IP communication, and WinCC Flexible SCADA software for real-time monitoring and control. Data were collected through functional testing, communication latency measurements, and reliability evaluations over 50 transfer cycles using a 3 kW load simulation. The results showed that the SCADA-ATS system successfully monitored transfer operations with a data update latency below 200 ms and an average transfer switching time of 2.31 seconds, fully complying with IEC 60947-6-1 standards. Furthermore, the system achieved a 100% transfer success rate and accurate voltage and frequency monitoring. In conclusion, the implemented SCADA system effectively improves operational reliability, monitoring transparency, and educational learning quality in laboratory power management systems.

Abstract

This study addresses the growing need for reliable thermal monitoring systems in industrial milling machines, particularly for spindle motors and bearings that are highly vulnerable to overheating during continuous machining operations. Excessive temperature can reduce component lifespan, increase maintenance costs, and cause unexpected production downtime. Therefore, this research aims to design and evaluate a PLC-SCADA-based temperature monitoring system capable of providing real-time monitoring, automatic alarm response, and historical data logging for milling machine operation. The research employed an experimental engineering approach using a Siemens S7-1200 PLC integrated with PT100 RTD temperature sensors, Modbus TCP/IP communication, and SIMATIC WinCC Flexible SCADA software. Four PT100 sensors were installed on the spindle motor and bearing housings to acquire thermal data continuously during idle, medium-load, and full-load machining conditions. The results demonstrated that the system successfully monitored temperature in real time with a SCADA update latency below 200 ms and communication latency averaging 3.6 ms. The maximum spindle motor temperature reached 98.4°C during full-load operation, while the implemented warning and automatic cooling system successfully prevented critical overheating conditions. Temperature measurement accuracy achieved a mean absolute error of 0.41°C compared with the reference instrument. In conclusion, the proposed PLC-SCADA monitoring system effectively improves machine reliability, operational safety, and predictive maintenance capability in industrial milling machine applications.
