### 4. Functionality
The W‑M2B401 operates as a remote digital output node in an RS‑485 Modbus network. A host controller (PLC, PAC, or PC) sends Modbus commands to set or reset output channels. Each output can drive external devices such as relays, solenoids, lamps, or alarms.
Typical Use Cases:
- Industrial process control and automation
- Building and energy management systems
- Machine control and equipment monitoring
- Security and access control systems
- Laboratory and test automation
Operation Principle:
- The host transmits Modbus function codes to the module.
- The module updates its output states accordingly.
- Programmable power‑on and safety values ensure deterministic behavior during startup or communication loss.
- The system watchdog monitors host communication; if a timeout occurs, outputs revert to predefined safe states.
Compatibility:
- Works with any Modbus/RTU master device.
- Integrates with SCADA, HMI, and PLC systems supporting Modbus.
- Compatible with Advanio’s RS‑232/RS‑485 and USB/RS‑485 converters and repeaters.
