### 4. Functionality

Operating Principle:
The ND‑6060 acts as a remote digital I/O node on an RS‑485 network. A host computer or controller issues ASCII commands to read input states or set relay outputs. The module’s microprocessor interprets these commands, updates internal registers, and drives the relays or reports input status accordingly.

Use Cases & Applications:
- Industrial automation and process control
- Building management and HVAC systems
- Remote equipment switching and monitoring
- Alarm and safety interlock systems
- Energy management and lighting control
- Laboratory instrumentation and test stands

Compatibility:
- Fully compatible with other NuDAM‑6000 modules (analog, digital, counter/frequency).
- Communicates via standard RS‑485 converters (e.g., ND‑6520, ND‑6530, ND‑6531).
- Supported by ADLINK’s NuDAM Administration Utility and third‑party SCADA or PLC software capable of serial ASCII communication.
