Description

The Honeywell 8C-PCNT05 (Part Number 51454363-275) is a Series 8 C300v5 Controller Module engineered for continuous control strategy execution, complex process loops, and high-throughput field communication within the Honeywell Experion PKS system architecture. Built on dual-core processing hardware, this fifth-generation C300 controller significantly expands execution resources and communication throughput compared to legacy C300v3 hardware.

Operating within the Honeywell Control Execution Environment (CEE), the Honeywell 8C-PCNT05 51454363-275 provides 32 MB of CEE user memory and 9000 execution units for intensive process logic, loop execution, and system-wide peer-to-peer data distribution. The module features factory conformal coating (coated 5, 6) to protect internal circuit assemblies against aggressive atmospheric conditions, chemical gases, and moisture encountered in demanding process control environments.

The unit connects directly to standard Series 8 mounting carriers, interfacing seamlessly across Fault Tolerant Ethernet (FTE) control networks. Supported on Experion PKS software releases R520.2 and onwards, the controller pairs with the dedicated 50182539-001 RAM charger module to ensure non-volatile retention of control configurations during main power supply interruptions.

Features

• Dual-Core Processing Hardware: Built with a dual-core architecture delivering 9000 processing execution units for high-demand control algorithms and communications.
• Expanded CEE Memory Capacity: Features 32 MB of dedicated CEE user memory for large-scale control strategy storage, function blocks, and sequential operations.
• Enhanced Peer Communication: Supports up to 8 Peer Gateway Module (PGM) connections per C300 node for scalable network architecture expansion.
• High Data Access Rate: Achieves an overall display data access response rate of 4000 PPS and a peer communication rate of 2000 PPS.
• Peer Initiator and Target Capacity: Delivers up to 2000 PPS incoming initiator pull/get subscribe rates and 2000 PPS outgoing target publish rates.
• High-Density Update Rates: Handles up to 200 peer capacity at 100 ms, 400 at 200 ms, 1000 at 500 ms, and 2000 at 1 sec update choices.
• Dedicated Power Backup: Designed to pair with the 50182539-001 RAM charger module to protect runtime data during power interruptions.
• Conformal Coated Protection: Factory conformal coating (coated 5, 6) safeguards electronic components in corrosive and harsh industrial atmospheres.

Applications

• Experion PKS Process Control: Central control processing engine executing continuous loops, complex interlocks, and batch recipes.
• Large-Scale Plant Automation: Distributed control operations across chemical, refining, petrochemical, and power generation facilities requiring high tag counts.
• High-Speed Controller Networking: Peer-to-peer real-time data exchange across multiple C300 controller nodes via Fault Tolerant Ethernet (FTE).
• Process Subsystem Integration: Managing high-density Series 8 I/O modules, smart transmitters, and fieldbus interfaces.

Installation Guidelines

1. Inspect the 8C-PCNT05 module and carrier assembly to ensure slot contacts are clean and free of debris.
2. Isolate power to the Series 8 mounting carrier before physically installing or replacing controller hardware.
3. Align the module's edge connectors with the designated C300 slot on the Series 8 carrier.
4. Push the unit firmly into the carrier until the mechanical retaining latch fully engages.
5. Connect the 50182539-001 RAM charger unit to the dedicated backup terminal on the controller.
6. Verify redundant Fault Tolerant Ethernet (FTE) cabling connections to qualified Cisco 9200 switch ports.
7. Apply system power and monitor diagnostic LEDs during system initialization and boot sequence.

Configuration / Commissioning / Replacement Guidelines

Configuration Guidelines

• Program and configure control strategies using Honeywell Control Builder on Experion PKS release R520.2 or higher.
• Assign unique FTE node addresses and verify subnet settings prior to performing initial strategy downloads.

Commissioning Recommendations

• Monitor CEE user memory consumption within Control Builder to optimize block assignments within the 32 MB limit.
• Verify peer-to-peer publication rates and PGM connection paths across configured controller nodes.
• Check charging voltage status for the connected 50182539-001 RAM charger to ensure battery health.

Replacement Recommendations

• Cross-Generational Redundancy Constraint: The 8C-PCNT05 (C300v5) module cannot be paired in a redundant set with an 8C-PCNT03 (C300v3) module, as different hardware generations will not synchronize redundancy states.
• Perform a full system database and parameter backup in Control Builder before removing an existing controller module.
• Always ensure the replacement 8C-PCNT05 unit is installed with the correct 50182539-001 RAM charger model rather than legacy charger units.
