### 4. Functionality

The W‑M1B111 functions as a remote analog input module within an RS‑485 Modbus network. It converts analog voltage signals from sensors or transducers into digital data for supervisory control systems such as PLCs, PACs, or SCADA hosts.

Operation Principle:
- Each input channel uses a dedicated front‑end circuit and A/D converter pair (two channels per ADC) for simultaneous sampling and high noise immunity.
- The module communicates with the host via Modbus/RTU commands over RS‑485.
- The host polls the module for input data; the module responds with digitized values in hexadecimal or engineering units.
- Built‑in watchdogs monitor both module operation and host communication, ensuring automatic recovery or safe‑state output on fault detection.

Typical Applications:
- Industrial process monitoring and control
- Remote data acquisition systems
- Energy management and power distribution monitoring
- Building automation and HVAC control
- Laboratory instrumentation and test systems
- Security and environmental monitoring
- Supervisory control and data acquisition (SCADA) networks

Compatibility:
- Compatible with standard Modbus/RTU masters (PLCs, HMIs, PCs).
- Integrates with Advanio’s Wolf Series digital and analog I/O modules.
- Works with Advanio RS‑232/RS‑485 or USB/RS‑485 converters and repeaters.
