### 4. Functionality

Operating Principle:
The WiFio‑201 functions as a remote analog output module within a distributed control or monitoring system. It receives digital commands from a host controller (PLC, PAC, SCADA, or PC) via Modbus‑TCP over Wi‑Fi/LAN or Modbus‑RTU over serial lines. The module converts these digital commands into precise analog voltage or current outputs to drive actuators, valves, transducers, or other field devices.

Typical Use Cases:
- Process control and automation (flow, pressure, temperature regulation)
- Building management systems (HVAC, lighting control)
- Energy management and power distribution monitoring
- Laboratory instrumentation and test automation
- Remote analog signal generation in distributed I/O networks
- Integration with wireless SCADA or cloud‑based IoT platforms

Compatibility:
- Fully interoperable with Modbus‑compliant controllers and software (e.g., Siemens, Schneider, Allen‑Bradley, Beckhoff, and open‑source SCADA systems).
- Supports Advanio’s Wolf series configuration utilities and ARIO software for Windows.
- Backward compatible with RS‑485 Wolf modules for hybrid wired/wireless networks.
