### 4. Functionality

Operating Principle:
The WiFio‑111 functions as a remote analog‑input acquisition node within a Modbus network. It converts analog voltage or current signals from sensors into digital data and transmits them via Modbus‑TCP (over Wi‑Fi/LAN) or Modbus‑RTU (over RS‑485). The host controller—PLC, PAC, or SCADA system—polls the module for data and can configure channel parameters through standard Modbus registers.

Use Cases and Applications:

- Industrial process monitoring and control
- Energy‑management systems and power‑distribution monitoring
- Building automation and HVAC control
- Laboratory instrumentation and data logging
- Security and environmental monitoring
- Remote telemetry and supervisory control (SCADA)
- Automatic test and measurement systems

Compatibility:
Fully compatible with Modbus‑compliant controllers, HMIs, and SCADA software. Supports integration with Advanio’s Wolf‑series wired modules and computing platforms. Configuration and diagnostics can be performed via Advanio ARIO Utility software (Windows) or mobile Advanio App (Android/iOS).
