### 4. Functionality

Operating Principle:
The WiFio‑108 functions as a remote data‑acquisition and monitoring module. Each thermocouple channel converts analog temperature signals into digital data via a 16‑bit ADC. The embedded controller processes and transmits these readings through Modbus‑TCP (Ethernet/Wi‑Fi) or Modbus‑RTU (serial) to supervisory systems such as PLCs, SCADA, or industrial PCs.

Use Cases and Applications:
- Industrial process temperature monitoring and control
- Energy management and environmental data logging
- Building automation and HVAC systems
- Laboratory and test‑bench instrumentation
- Security and safety monitoring (fire/explosion prevention)
- Remote supervisory control and data acquisition (SCADA)
- Smart‑factory and Industry 4.0 IoT integration

Compatibility:
Fully compatible with standard Modbus‑TCP/RTU masters, including PLCs, PACs, DCS, and SCADA software. Supports integration with Advanio’s Wolf‑series modules and ARIO configuration utility.
