Key Features

1. Network Security Firewall: Filters and secures communication between the C300 controller and field I/O, preventing unauthorized access and network attacks.

2. Deterministic Communication: Ensures real‑time, reliable data transmission for critical process control loops.

3. Redundancy Support: Works with redundant C300 controllers and I/O networks for high‑availability systems.

4. Fault Diagnostics: LED indicators for power, network status, and fault detection; supports system‑level diagnostics.

5. Industrial Hardening: Conformal coated PCB, wide temperature range, and robust construction for chemical, power, oil & gas, and pulp & paper plants.

Applications

• Process Industries: Chemical, petrochemical, power generation, oil & gas, pulp & paper, pharmaceuticals.

• System Role: Network security and communication isolation for Honeywell Experion PKS / C300 DCS.

• Typical Uses:

  • Securing communication between controllers and remote I/O.

  • Isolating control networks from plant LANs to prevent cyber threats.

  • Ensuring deterministic data flow for critical control applications.

Installation & Wiring

1. ESD Protection: Use anti‑static wristbands and ESD‑safe work surfaces.

2. Power Off: De‑energize the I/O chassis before insertion/removal.

3. Chassis Installation: Insert into a C300 I/O slot and secure with mounting screws.

4. Network Wiring:

   • Connect Ethernet cables to control network and I/O network ports.

   • Connect UCN cable to the controller’s UCN port.

   • Use shielded twisted‑pair cable for all network connections.

5. Configuration: Use Experion PKS software to set network parameters, firewall rules, and redundancy settings.

Maintenance

• Inspection: Check LED status, cable connections, and 24 VDC power supply.

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

• Troubleshooting:

  • Verify network cable integrity and connections.

  • Check for network conflicts or IP address issues.

  • Use system diagnostics to isolate communication faults.

Safety Notes

• Disconnect chassis power before installation/maintenance.

• Operate within rated temperature/humidity limits.

• Do not modify or disassemble (voids warranty).

• Comply with site ESD and safety procedures.
