 This code turns an Arduino Opta™ into an OPC UA-compatible device, enabling real-time data monitoring and control via Ethernet. It initializes an OPC UA server, reads analog/digital inputs, controls relays based on voltage thresholds, and exposes device states as OPC UA nodes for external systems. The system supports expansion modules, synchronizes time using NTP, and provides real-time feedback through LEDs and logs.

-The HMI, developed using the Ignition Plataform, is a **Voltage Level Monitor** specifically designed for real-time monitoring and management of system voltage levels. The interface categorizes voltage states into **No Voltage**, **Safe Voltage**, **Alert Voltage**, and **Critical Voltage**, using clear color-coded indicators for immediate operator recognition. A dedicated Voltage Measurement section displays precise, real-time readings, while a **System Status** indicator ensures operators are informed of the system's operational state.
