### 4. Functionality

Operating Principle:
The WiFio‑402 acts as a remote digital I/O expansion node. It receives Modbus commands from a host controller (PLC, PAC, SCADA, or PC) via Ethernet, Wi‑Fi, or RS‑485. The module interprets these commands and switches its 32 digital outputs accordingly, while simultaneously reporting the state of its 16 digital inputs.

Use Cases and Applications:
- Industrial process control and automation
- Remote data acquisition and monitoring
- Energy management and power distribution systems
- Building automation and HVAC control
- Security and access control systems
- Laboratory and test automation
- Supervisory control and data acquisition (SCADA)
- Direct digital control (DDC) and embedded control systems

Compatibility:
Fully compatible with standard Modbus‑TCP/RTU masters such as Siemens, Schneider, Allen‑Bradley, Beckhoff, and open‑source SCADA platforms (Ignition, Citect, LabVIEW, etc.).

Logic Configuration:
Each output channel can be set to normal or inverted logic, enabling seamless replacement of legacy modules with differing signal conventions.

Watchdog Functions:
- Module Watchdog (Hardware): Automatically resets the module if internal logic hangs for > 1.6 s.
- System Watchdog (Software): Monitors host communication; if polling timeout occurs, outputs revert to predefined safe states.
