Overview Specifications Features Applications Lifecycle FAQ Recommended Models

Overview

TC-CCN014 is a core control network interface module designed by Honeywell Process Solutions for TDC 3000 and Experion PKS systems. It acts as the bridge between the Local Control Network (LCN) and the Universal Control Network (UCN), functioning as a Network Interface Module (NIM) and as a communication processor in the Global User Station (GUS) for high‑speed data routing and protocol conversion.

The module supports dual‑redundant A/B side configurations with sub‑second seamless switching, making it ideal for continuous process industries such as refining, power generation, and metallurgy. It is fully compatible with legacy TDC 3000 systems and modern Experion PKS migration architectures, protecting existing capital investments.

Features

Redundancy & reliability

  • Dual redundant design — primary and backup modules synchronise via fast heartbeats; sub‑second failover transparent to operator stations and controllers.
  • Redundant ControlNet media — dual BNC ports monitor both A and B networks, eliminating single points of failure.
  • Hot‑swap capable — replace a standby module online without interrupting the process.

Performance & compatibility

  • Protocol conversion bridge — efficient protocol stack for LCN/UCN and ControlNet, ensuring low‑latency data throughput.
  • Broad compatibility — works seamlessly with legacy TDC 3000 and supports smooth migration to Experion PKS.
  • Industrial grade — overvoltage/overcurrent protection, EMI immunity, and conformal‑coated PCB for harsh environments.

Applications

TC-CCN014 is deployed in mission‑critical infrastructure where deterministic communication and high availability are essential.

Refining & petrochemical
Power generation (thermal/nuclear)
Metallurgy & mining
Water & wastewater
Chemical continuous processes
Experion PKS migration projects
Remote RTU data acquisition
DCS redundant network backbone
Common pairings: used with C300 controllers, 8C‑PCNT02, 8C‑TAIDA1 and other modules to form the Experion PKS control link.

Lifecycle & Replacement

Discontinued manufacturer has officially stopped production

End‑of‑Life (EOL) date: According to Honeywell bulletins, TC‑CCN014 has been listed as a legacy product for several years. Only stock, tested used/refurbished units are currently available through third‑party channels.

Migration & replacement considerations:

Suggested alternative models: Honeywell recommends migrating to the Experion PKS platform. Potential replacements include TC‑CCN012 (non‑redundant) or newer C300‑compatible communication modules such as 8C‑PCNT02. Direct drop‑in replacement is not guaranteed — the following must be evaluated:
  • Firmware versions must match the existing system, otherwise redundancy synchronisation may fail.
  • For third‑party or refurbished units, carefully test the ControlNet physical layer (75Ω impedance, terminators).
  • System configuration (Control Builder) will require node address and network parameter re‑assignment.
  • Perform full failover tests to verify seamless switchover logic.
Related or similar models: TC‑CCN012, TC‑CCR012, 8C‑PCNT02, 8C‑PAOHA1

Recommendation: For systems still running TC‑CCN014, we advise planning a migration to the new Experion PKS architecture and stocking qualified spares to ensure continuity during the transition.

FAQ – Frequently Asked Questions

Q1: What is the main function of the TC‑CCN014?

It is a redundant network interface module for Honeywell DCS systems. Its primary role is to bridge the LCN and UCN networks, or to serve as a ControlNet communication interface for C300 controllers, ensuring high‑speed, redundant data exchange between controllers, operator stations, and I/O subsystems.

Q2: Does the module support online hot‑swapping?

Yes. In a redundant A/B configuration, the standby module can be replaced while the system is running without interrupting control. Always verify that the active module is healthy and follow proper ESD procedures.

Q3: Is TC‑CCN014 compatible with standard Ethernet?

No. It uses the ControlNet protocol with RG‑6 coax cabling and BNC connectors, requiring 75Ω terminators. It cannot be directly connected to standard Ethernet switches.

Q4: What should I do if the LED shows a synchronisation error?

This is usually caused by mismatched firmware versions or a duplicate node address. Use Control Builder to verify that both modules have the same firmware, check the node address, and inspect the coax cabling and terminators for faults.

Q5: The module is discontinued — what are my options?

Honeywell officially recommends migrating to the Experion PKS architecture. Consider TC‑CCN012 (non‑redundant) or newer C300‑based communications modules. However, these are not “plug‑and‑play”; they require careful evaluation of firmware compatibility, system re‑configuration, and physical layer adjustments. Professional engineering support is strongly advised.
