3. Built-In Diagnostics: LED status indicators and BIST functionality simplify troubleshooting, allowing maintenance teams to quickly identify communication faults or power issues with HONEYWELL 51304362-350.
4. Dual LCN Ring Support: Compatibility with redundant LCN rings provides fault tolerance, minimizing downtime if a single LCN cable or port fails.
5. Robust Industrial Design: HONEYWELL 51304362-350 is engineered for harsh industrial environments, with resistance to vibration, temperature fluctuations, and electrical interference—ideal for refineries and chemical plants.

4. Application Fields & Cases

4.1 Application Fields

• Oil & Gas: Refinery TDC 3000 system communication, offshore platform legacy DCS data transfer, pipeline control system interface
• Petrochemical: Chemical plant batch process monitoring, polymerization reactor control system communication, storage terminal TDC 3000 integration
• Power Generation: Coal-fired power plant boiler control system interface, turbine monitoring data transmission, legacy DCS alarm management

4.2 Typical Cases

1. Refinery TDC 3000 System Upgrade: A major U.S. refinery replaced aging CIM modules with HONEYWELL 51304362-350 to restore LCN communication between PM controllers and Universal Stations. The module’s compatibility with existing TDC 3000 hardware avoided a costly full DCS upgrade, saving $1.2M while maintaining reliable process control.
2. Chemical Plant Batch Process Control: A European petrochemical facility used HONEYWELL 51304362-350 to synchronize batch recipe data between TDC 3000 PM controllers and operator workstations. The module’s low latency ensured real-time recipe adjustments, reducing batch cycle time by 5% and improving product consistency.
3. Power Plant Boiler Control: An Asian coal-fired power plant deployed HONEYWELL 51304362-350 to relay boiler pressure/temperature data from TDC 3000 controllers to the central monitoring station. The dual LCN ring support prevented a communication outage during a cable fault, avoiding unplanned downtime and $500,000 in lost generation.

6. Selection Suggestions & Precautions

6.1 Selection Suggestions

1. Legacy DCS Requirements: Choose HONEYWELL 51304362-350 for Honeywell TDC 3000/PM systems requiring LCN communication between controllers and workstations; generic CIM modules may lack full compatibility and diagnostic features.
2. Redundancy Needs: Opt for HONEYWELL 51304362-350 if operating dual LCN rings for fault tolerance; non-redundant CIMs increase downtime risk in critical applications.
3. Maintenance & Support: Select HONEYWELL 51304362-350 for access to Honeywell’s legacy DCS support and replacement parts; third-party modules may have limited availability.

6.2 Precautions

1. Installation Guidelines:
   • Install HONEYWELL 51304362-350 in TDC 3000 PM racks only; use certified LCN coaxial cables (maximum distance 1.2km per segment) and terminate LCN rings with 75Ω resistors at both ends.
   • Ensure proper grounding (≤4Ω) for the module and LCN cables to minimize electrical interference and maintain communication reliability.
2. Configuration Notes:
   • Configure LCN node addresses via the TDC 3000 Universal Station to avoid conflicts (each CIM requires a unique LCN address).
   • Enable alarm logging and diagnostic alerts to monitor HONEYWELL 51304362-350 health and detect communication faults early.
3. Troubleshooting:
   • For LCN communication failures: Check cable termination, verify node addresses, and use the maintenance RS-232 port to run diagnostic tests via the LCN Configuration Utility.
   • For power faults: Inspect the PM rack power supply and module connections; replace the module if the power LED remains off after verifying input power.
4. Maintenance:
   • Inspect LCN cable connectors and module ports annually for corrosion or damage; clean with isopropyl alcohol to remove dust and debris.
   • Stock spare HONEYWELL 51304362-350 modules—legacy DCS components have limited production runs, and lead times may exceed 12 weeks.
   • Coordinate with Honeywell’s legacy DCS support team for firmware updates and compatibility checks before system modifications.
