IOT SCADA Security

Completed 2025 • Factory I/O simulation with Modbus server and Python Modbus TCP client for supervision/control

A SCADA training project using Factory I/O to simulate a sorting and packaging line, controlled via both Control I/O and a Python Modbus TCP client. The system maps sensors, actuators, counters, and setpoints to Modbus coils/registers, enabling supervision and control (start/stop, emergency stop, routing by color, speed/setpoints, counters, alarms). The lab emphasizes industrial protocol handling, safety states, and supervision logic for SCADA security scenarios.
