Description

The Honeywell 8C-PCNT03 (Part Number 51454363-375) is a C300 Controller Processor Module designed for real-time control strategy execution, batch processing, and process field management within the Honeywell Experion PKS Series 8 DCS architecture. Operating on the C300v3 hardware platform, this single-core controller unit executes deterministic control logic via Honeywell Control Execution Environment (CEE) software.

Built for heavy-duty industrial process environments, the Honeywell 8C-PCNT03 51454363-375 features conformal coating on its circuit assembly to prevent corrosion from airborne contaminants, high humidity, and chemical exposure. The unit provides dedicated processing resources and high-capacity communication handling across standard Fault Tolerant Ethernet (FTE) control networks.

The controller module hosts 18 MB of CEE user memory and supports up to 4 Peer Gateway Module (PGM) network connections. It integrates directly into standard Series 8 carrier assemblies, interfacing with local I/O modules and peer controllers across distributed process networks.

Features

• Control Execution Resource: Delivers 5500 processing execution units (Us) available for CPU consumption in loop execution and logic processing.
• Dedicated CEE Memory: Equipped with 18 MB of CEE user memory dedicated to strategy configuration, continuous control blocks, and sequential operations.
• Single-Core Architecture: Utilizes a single-core processor engine optimized for deterministic cycle execution.
• System Release Compatibility: Supported across Experion PKS software releases R110, R120, R500, R510, and R520.
• Memory Backup Architecture: Interfaces with the 51454475-100 RAM charger module to ensure non-volatile program retention during main power failure events.
• PGM Network Expansion: Supports up to 4 Peer Gateway Module (PGM) connections per C300 controller node.
• Data Access Throughput: Provides a conventional overall data access response rate of 2500 PPS.
• Subscribed Parameter Capacity: Handles up to 4000 total subscribed parameters for display data access.
• Peer-to-Peer Publishing: Supports peer-to-peer initiator pull/get and target publish rates up to 1000 PPS.
• Conformal Coating Protection: Features factory conformal coating (coated 1, 3, 4) to withstand harsh ambient atmospheric environments.

Applications

• Distributed Process Control: Primary processing engine for continuous process loops in chemical, refining, and energy production plants.
• Experion PKS Automation: Control engine executing CEE control strategies, function blocks, and process interlocks.
• Batch Automation: Sequence execution and recipe execution in pharmaceutical and specialty chemical manufacturing.
• Subsystem Interface Control: Orchestration of field I/O modules, serial interfaces, and peer controller data exchanges over FTE.

Installation Guidelines

1. Inspect the 8C-PCNT03 module and carrier base for physical cleanliness prior to mounting.
2. Ensure system power supplies to the target Series 8 mounting carrier are isolated or properly configured according to plant safety practices.
3. Align the rear edge connectors of the 8C-PCNT03 module with the dedicated controller slot on the Series 8 carrier assembly.
4. Press the module firmly into place until the locking mechanism engages securely with the carrier.
5. Connect the 51454475-100 RAM charger module to its designated backup terminal on the controller assembly.
6. Confirm properly grounded carrier shielding and verify FTE Ethernet cabling connection to network switches.
7. Apply power and verify system LED status indicators proceed through initial boot diagnostic routines.

Configuration / Commissioning / Replacement Guidelines

Configuration Guidelines

• Use Honeywell Control Builder within a compatible Experion PKS release (R110, R120, R500, R510, or R520) to define CEE control execution strategies.
• Assign proper FTE node addressing and controller memory allocations prior to downloading parameter files.

Commissioning Guidelines

• Verify communication throughput to connected I/O channels and peer controllers.
• Monitor memory consumption metrics to ensure strategy size fits within the 18 MB CEE user memory limit.
• Confirm RAM charger module charging voltage and backup functionality.

Replacement Recommendations

• Cross-Generational Redundancy Constraint: The 8C-PCNT03 (C300v3) module cannot be paired with an 8C-PCNT05 (C300v5) module in a redundant set, as cross-generational hardware will not synchronize redundancy states.
• When replacing an existing 8C-PCNT03 module, upload and back up current controller databases and parameter settings in Control Builder prior to removing the hardware unit.
• Verify that replacement units retain the 51454475-100 RAM charger module specification to prevent memory loss during power cycles.
