### 4. Functionality
Operation Principle:
The module acts as a Modbus/TCP server on an Ethernet network. A host controller or SCADA client issues Modbus function codes (01–06, 15, 16) to read or write coil/register data corresponding to the DI/DO channels. The built‑in microcontroller handles I/O scanning, isolation, and communication.

Use Cases / Applications
- Industrial automation and process control
- Building management and HVAC systems
- Remote equipment monitoring and alarm signaling
- Energy management and smart‑grid I/O nodes
- Laboratory or test‑bench data acquisition

Compatibility
- Works with any Modbus/TCP‑capable PLC, HMI, or SCADA software.
- Supported by ExpertDAQ Utility, Modbus OPC Server, and custom applications via DLL or ActiveX interfaces.
- Web browser access through built‑in HTTP server.
