Key Features

1. LCN Network Master Control: Manages LCN data routing, node addressing, and communication scheduling.

2. Redundant Communication: Dual LCN‑A/B ports enable automatic failover for high network reliability.

3. High‑Performance Processing: LCNP‑4 processor ensures low‑latency real‑time data handling and control execution.

4. System‑Level Diagnostics: LED indicators and TDC3000 system tools support fault detection and troubleshooting.

5. Standard Chassis Integration: Fits in standard 5/10‑slot TDC3000 I/O chassis for easy installation and replacement.

6. EMI/RFI Protection: Rugged design with multi‑layer circuit shielding for industrial environment durability.

Applications

• Industries: Power generation, petrochemical, oil & gas, pulp & paper, metallurgy, pharmaceuticals.

• System Role: Core LCN communication and control processor for TDC3000/TPS DCS.

• Use Cases:

  • Real‑time data exchange between LCN nodes (controllers, workstations, I/O modules).

  • Coordination of redundant LCN networks for uninterrupted operation.

  • Execution of network management and diagnostic functions.

Installation & Wiring

1. Power Off: De‑energize the I/O chassis before inserting or removing the board.

2. Chassis Installation: Insert into an available slot and secure with mounting screws.

3. LCN Wiring: Connect LCN‑A/B cables to the redundant ports; use shielded twisted‑pair cables.

4. Configuration: Use TPS/TDC3000 engineering tools to set network parameters and redundancy options.

5. ESD Precautions: Wear anti‑static wristbands and use ESD‑safe surfaces during handling.

Maintenance

• Periodic Inspection: Check for loose connections, damaged cables, or LED fault indications.

• Cleaning: Remove dust with a dry, soft cloth; avoid liquid cleaners.

• Replacement: Use only original or Honeywell‑authorized replacement parts.

• Fault Handling:

  • Verify LCN cable integrity and redundant port status.

  • Check backplane power supply (5 VDC).

  • Use TDC3000 diagnostics to identify board or network faults.

Safety Notes

• Perform all wiring and maintenance with chassis power disconnected.

• Do not exceed rated temperature and humidity limits.

• Unauthorized modification or disassembly is prohibited.

• Comply with site safety rules and ESD procedures.
