HONEYWELL CC-PCNT01

Description

HONEYWELL CC-PCNT01 is a communication network module, specifically a Controller Network Interface Module, for Honeywell’s Experion Process Knowledge System (PKS). This module, the CC-PCNT01, provides the essential high-speed, deterministic network connectivity for C Series Process Controllers (like the C200, C300) on Honeywell’s proprietary control-level network. Detailed technical information can be found on the product page: HONEYWELL CC-PCNT01. The HONEYWELL CC-PCNT01 is a critical component for enabling reliable, real-time data exchange and controller redundancy within the Experion control system architecture.

Product Description

The HONEYWELL CC-PCNT01 is a printed circuit board assembly that installs into a dedicated slot within a Honeywell C200 or C300 Process Controller chassis. Its primary function is to interface the controller with Honeywell’s proprietary Control Network (also known as the Experion ControlNet or legacy TPN/LAN). This network is separate from the plant information network and is optimized for fast, deterministic, and highly reliable communication between controllers, I/O modules, and other control system devices. The CC-PCNT01 module handles the protocol conversion and data packaging, ensuring that process data, alarms, and control commands are transmitted with high integrity and minimal latency. It is fundamental to creating a tightly integrated and synchronized distributed control system.

Product Parameters

• Brand and Manufacturer: HONEYWELL.
• Product Series: Experion PKS C Series.
• Product Type: Controller Network Interface Module.
• Compatible Controllers: Designed for C200 and C300 Process Controllers.
• Network Type: Interfaces with Honeywell’s proprietary Control Network (a deterministic, token-passing network like a legacy TPS HiWAY or TDC 3000 Local Control Network (LCN) derivative, or a modern Experion-specific control bus).
• Function: Enables peer-to-peer communication between controllers, communication with I/O nodes, and supports controller redundancy by synchronizing the primary and backup controller over this dedicated link.
• Data Transfer Rate: High-speed data transfer suitable for real-time control (specific speed defined by the network standard).
• Physical Connection: Uses a specialized coaxial cable or twisted-pair connection with a specific Honeywell connector.
• LED Indicators: Status LEDs for power, network activity, fault, and redundancy status.
• Redundancy Support: Essential for creating redundant controller pairs; two CC-PCNT01 modules (one in each controller) communicate to keep the backup controller synchronized.

Advantages and Features

The key advantage of the HONEYWELL CC-PCNT01 is its provision of a dedicated, deterministic, and highly reliable control network isolated from the less predictable plant IT network. This separation is crucial for maintaining control system performance and security. The module enables fast peer-to-peer communication between controllers, allowing for complex control strategies that span multiple units. A critical feature is its integral role in Honeywell’s controller redundancy scheme, ensuring bumpless switchover in case of a primary controller failure. The module is designed for industrial robustness, with high noise immunity and reliability. Using the genuine HONEYWELL CC-PCNT01 ensures optimal system performance, guaranteed compatibility, and access to Honeywell’s full support services.

Application Cases in Various Fields

• Refinery Unit Control: Connecting multiple C300 controllers managing different sections of a crude distillation unit (e.g., preheat, furnace, column) on a dedicated control network for coordinated operation.
• Chemical Plant Batch Sequencing: Enabling fast communication between a main sequence controller and subordinate unit controllers for precise timing in a batch reactor process.
• Power Plant Coordinated Control: Allowing a master controller to send setpoints and receive feedback from multiple boiler and turbine control subsystems over a deterministic network.
• Controller Redundancy in Critical Processes: Forming the communication link between paired primary and backup controllers for a safety-critical process like gas compression, ensuring continuous operation.
• Large-Scale Distributed I/O Communication: Serving as the network interface for a controller to communicate with remote I/O racks located throughout a plant area.

Comparison with Competing Products

As a proprietary network interface for Honeywell’s Experion system, the CC-PCNT01 has no direct competitors. Its function is analogous to the controller network cards in other DCS platforms, such as Emerson’s DeltaV Controller Ethernet Card, Siemens’ SIMATIC PCS 7 AS-OS LAN interface, or ABB’s 800xA Controller Network Connection. However, these are not interchangeable. The CC-PCNT01 is specifically engineered for Honeywell’s control network protocol and controller hardware. The choice is inherent to the selection of the Experion PKS platform; users of that system require this module for core controller networking and redundancy.

Selection Suggestions and Precautions

1. Confirm Controller Model: Verify that your C200 or C300 controller requires the CC-PCNT01 module. Some newer controllers may have integrated network interfaces.
2. Network Topology Planning: The control network has specific rules for termination, cable length, and the number of nodes. Design the network layout according to Honeywell’s Experion installation guidelines.
3. Redundancy Pairing: For redundant controller configurations, you will need one CC-PCNT01 module for each controller in the pair. They must be configured as a redundant set in the system software.
4. Handle with ESD Precautions: The module contains static-sensitive components. Use proper ESD handling procedures during installation.
5. Software Configuration: The module must be recognized and configured within the Experion Engineering Studio software. Its network address and parameters must be set correctly.
