Core Functions

1. Peripheral Expansion: Connects TDC 3000 to 6 external devices (printers, scanners, serial devices).

2. I/O Signal Processing: Handles digital input/output, signal conditioning, and isolation.

3. Protocol Conversion: Translates LCN protocols to RS-485/Modbus for peripheral communication.

4. Data Buffering: Caches data between system and peripherals to prevent loss.

5. Fault Diagnosis: Detects port errors, device disconnections, and signal anomalies; reports alarms.

6. System Expansion: Extends DCS I/O capacity for complex process control.
