Whether you're modernizing legacy TDC 3000 systems or building greenfield automation infrastructure, this controller provides the computational foundation for reliable, scalable process control.

With SIL 2 certification, cybersecurity-ready architecture, and support for up to 4,000 I/O points in redundant configurations, the CC-PCNT02 transforms raw sensor data into optimized process performance—delivering measurable improvements in yield, quality, and operational efficiency.

Core Capabilities & Technical Advantages

→ Deterministic Execution Engine: 32-bit RISC processor with 64MB SDRAM ensures control loops execute within guaranteed time windows, eliminating jitter and maintaining process stability even under peak computational loads.

→ Fault-Tolerant Redundancy: Dual controller configurations provide bumpless failover in under 50ms, synchronizing control states in real-time to eliminate single points of failure in critical process loops.

→ Massive I/O Scalability: Single controller manages 2,000 I/O points; redundant pairs handle 4,000 points with automatic load distribution, reducing hardware footprint and simplifying system architecture.

→ Advanced Algorithm Library: Native support for PID, cascade, ratio, feedforward, and model predictive control (MPC) enables sophisticated multi-variable optimization without external computing resources.

→ Integrated Diagnostics & Predictive Maintenance: Continuous health monitoring tracks processor load, memory utilization, communication integrity, and I/O status—triggering alerts before degradation impacts production.

→ Cybersecurity Foundation: Role-based access control, encrypted Ethernet communications, and comprehensive audit logging meet IEC 62443 industrial cybersecurity standards for connected operations.

Industry Applications & Process Solutions

✓ Refinery & Petrochemical Operations: Coordinate distillation column control, reactor temperature management, and product blending across multi-unit complexes. The CC-PCNT02's high-speed processing handles the rapid dynamics of exothermic reactions while maintaining safety interlocks and emissions compliance.

✓ Chemical Batch Manufacturing: Execute ISA-88 batch recipes with precise phase transitions and material tracking. Electronic batch records with 21 CFR Part 11 compliance support pharmaceutical and specialty chemical production where regulatory traceability is mandatory.

✓ Power Plant Automation: Manage boiler-turbine coordination, combustion optimization, and auxiliary systems in combined-cycle and cogeneration facilities. Deterministic control maintains grid synchronization during load following and frequency regulation.

✓ Pulp & Paper Process Control: Regulate digester chemistry, bleaching sequences, and paper machine moisture profiles. The controller's analog control precision reduces quality variations and minimizes off-spec production.

✓ Water & Wastewater Treatment: Automate clarification, filtration, and disinfection processes with adaptive control that responds to influent variability. Real-time optimization balances treatment effectiveness against energy consumption.

Technical Specifications & Selection Guide

Selection Criteria: Choose the CC-PCNT02 when your application requires high-availability process control with deterministic performance. For applications with less than 1,000 I/O points and non-critical processes, consider C200 controllers. For safety instrumented systems requiring SIL 3, evaluate Safety Manager integration options.

Extended Integration & Connectivity Options

The CC-PCNT02 operates as the computational hub within Experion PKS architectures, communicating with field I/O modules via high-speed Control Network and interfacing with operator stations through redundant Ethernet backbones. The controller supports hot-swappable installation in standard DIN rail or rack-mount configurations, enabling maintenance without system shutdown.

Backward Compatibility: Seamlessly integrates with legacy TDC 3000 systems, allowing phased migration strategies that protect existing infrastructure investments while introducing modern control capabilities.

Third-Party Integration: OPC UA server functionality enables data exchange with MES, SCADA, and historian systems from vendors including Rockwell, Siemens, and Schneider Electric.

Cloud Connectivity: When paired with Honeywell Forge industrial IoT gateways, the CC-PCNT02 streams real-time process data to cloud analytics platforms for machine learning-based optimization and remote expert support.

Frequently Asked Questions

Q: What is the maximum distance between redundant controllers?
A: Redundant CC-PCNT02 controllers can be separated by up to 100 meters when connected via standard Ethernet cabling. For greater distances, use fiber optic media converters to extend redundancy links up to 2 kilometers.

Q: Can I upgrade from C200 to C300 controllers without replacing I/O modules?
A: Yes, C300 controllers are backward compatible with existing C200 I/O modules and carrier assemblies. The upgrade path requires only controller replacement and configuration migration via Control Builder software.

Q: How does the controller handle network communication failures?
A: The CC-PCNT02 includes configurable timeout and retry parameters for all communication interfaces. In the event of network loss, the controller continues executing local control strategies using last-known-good values or predefined safe states.

Q: What programming languages does the controller support?
A: The CC-PCNT02 is programmed using Honeywell's Control Builder IDE, which supports IEC 61131-3 languages including Function Block Diagram (FBD), Structured Text (ST), and Sequential Function Chart (SFC). Legacy TDC 3000 CL language is also supported for migration projects.

Q: Is the controller suitable for hazardous area installation?
A: The CC-PCNT02 carries Class I Division 2 certification for installation in non-incendive locations. For Zone 1/Division 1 hazardous areas, the controller must be installed in purged enclosures or safe-area control rooms with remote I/O in the field.

Q: What cybersecurity features protect against unauthorized access?
A: The controller implements multi-layer security including user authentication, role-based permissions, encrypted Ethernet communications (TLS 1.2), and comprehensive audit logging. Integration with Active Directory and RADIUS servers enables centralized access management.
