Honeywell CC-PCNT01, 1st Generation C300 Controller Module for Experion PKS Series C

Description

Honeywell CC-PCNT01, 1st Generation C300 Controller Module for Experion PKS Series C

Core Product Overview

CC-PCNT01 is the first-generation C300 DCS controller processor card for Honeywell Experion PKS Series C platform, OEM drawing PN: 51405046-175. It runs Honeywell deterministic CEE (Control Execution Environment), responsible for continuous PID regulation, sequence logic, batch control and I/O scanning. It must be matched with dedicated IOTA termination base CC-TCNT01, which provides 24VDC power, dual FTE ports and I/O Link bus terminals. It supports dual redundant hot-standby pairing for bumpless switchover. Successor model is CC-PCNT02, and the newer high-performance version is CC-PCNT05. Widely used in petrochemical, refinery, gas and power plant Experion PKS DCS cabinets. This is DCS process controller, not SIS safety controller (not FC-QPP-0001).

Professional Quality Control & Testing Standard Operating Procedures

All surplus and refurbished Honeywell CC-PCNT01 modules follow this inspection workflow:

1. Visual Inspection: Inspect PCB, gold edge fingers, front LED indicators, capacitors and soldering; verify Honeywell part label and revision.
2. IOTA Base Power Bench Test: Install on CC-TCNT01, apply 24VDC, confirm stable power rails, no overcurrent or cycling.
3. Boot & Firmware Validation: Complete power-on self-test, read firmware revision, confirm no permanent hardware fault codes.
4. CEE Control Strategy Test: Download Experion control strategy, verify deterministic scan, PID and sequence execution.
5. FTE & I/O Link Test: Test dual FTE links and I/O Link bus; verify communication with local and remote I/O modules.
6. Redundancy Switchover Test: Pair two CC- controllers, validate bumpless primary/secondary failover.
7. Thermal Soak Test: Run module at upper ambient temperature to expose intermittent memory, timing or connector faults.
8. Final Cleaning & Packaging: Clean edge contacts, reset configuration, ESD packaging with printed test certificate.

New / Refurbished Module Installation Guidelines

1. Pre-Installation Safety: Execute lockout-tagout; isolate rack 24V supply and FTE network to avoid process control interruption.
2. Rack & IOTA Check: Confirm CC-TCNT01 IOTA base is correctly mounted on Series C carrier, protective earth and cabinet ventilation.
3. Mechanical Insertion: Align CC- edge connector with CC-, insert smoothly and lock the module latch.
4. Network & I/O Wiring: Connect dual FTE cables and I/O Link cables to IOTA terminals; use Honeywell specified shielded cables.
5. System Configuration: Download control strategy and redundancy settings via Experion PKS engineering tools.
6. Offline Functional Test: Power rack offline; verify Run/Fault LEDs, FTE link status and I/O data refresh.
7. Commissioning & Acceptance: Test redundant switchover under fault conditions, confirm control strategy remains stable, archive project and test records.

Application Scenarios & Product Features

Typical Application Scenarios

• Experion PKS Series C DCS continuous process control
• Petrochemical, refinery, natural gas and power plant control cabinets
• Batch control, regulatory PID, interlock and advanced control applications
• Retrofit and spare replacement for legacy DCS installations

Core Product Features

• First-generation DCS controller for Experion PKS
• Deterministic CEE control engine for predictable control scan
• Dual FTE fault-tolerant Ethernet for communication with Experion servers and HMI
• Dual I/O Link bus to connect local and remote Series C I/O racks
• Supports dual redundant hot standby for high process availability
• Conformal coated PCB suitable for industrial cabinet environments
• Hot-swap capable; replacement requires process bypass and site work permit procedures
• Not a SIL safety SIS controller, cannot replace Safety Manager FC-QPP-0001

Frequently Asked Questions (FAQ)

A1: No. CC- is the mandatory IOTA base, providing power, FTE and I/O Link termination.

A2: CC- is the original first-gen . CC-PCNT02 is the revised second generation with enhanced firmware and diagnostics. They are not fully drop-in compatible without checking Experion software revision.

A3: No, it is standard DCS process controller. Honeywell SIL3 SIS uses Safety Manager FC-QPP-0001.

Q4: Is it hot-swappable? A4: Hardware supports hot swap, but removing the primary controller triggers redundancy switchover. Implement process bypass and work permit before replacement.

Q5: What are common failure modes? A5: Edge connector oxidation, FTE RJ45 port ESD damage, ageing capacitors, firmware corruption from voltage transients, memory faults.
