Honeywell CC-PCF901 51405047-176 Control Firewall Module

»Product Info«

Product description: The Honeywell CC-PCF901 (part number 51405047-176) is a dedicated Control Firewall 

Module engineered for seamless integration with the Experion PKS C300 Distributed Control System (DCS), functioning as a critical cybersecurity component in industrial automation setups. It delivers robust network 

isolation between segments of varying security levels (e.g., control-level I/O networks and plant-wide monitoring 

networks) to block unauthorized access, mitigate cyber threats, and prevent disruptive unintended data flows 

that could compromise critical process control operations. The module enforces strict access control policies, 

supports industrial communication protocols like Modbus TCP and OPC UA with protocol-specific filtering, and 

includes abnormal activity detection to identify potential network anomalies. Compliant with industrial 

cybersecurity standards such as IEC 62443, it offers optional redundancy for high-availability needs, integrates 

smoothly with Honeywell’s Experion PKS software for centralized configuration and monitoring, and is widely 

deployed in sectors like petrochemicals, power generation, and water treatment to safeguard control system 

integrity while enabling secure data exchange between authorized network segments.

»Function«

The Honeywell CC-PCF901 (Part Number: 51405047-176) is a process control firewall and industrial communication interface module within Honeywell’s C Series I/O portfolio, specifically designed to enable secure, reliable data exchange between the Experion PKS Distributed Control System (DCS) (e.g., C300 Controllers) and field devices or external systems in industrial automation environments. Its core function is to act as a secure communication bridge: it supports multiple industrial protocols (such as Modbus RTU/TCP, HART, and EtherNet/IP) to facilitate real-time transmission of process data (e.g., pressure, temperature, flow readings) and control commands between the central control layer and field equipment (e.g., transmitters, actuators, or third-party monitoring tools). As a process control firewall, it also implements robust security measures—including access control policies, data packet filtering, and unauthorized connection blocking—to prevent cyber threats or unintended access to the critical control network, safeguarding the integrity and availability of the DCS. Additionally, it provides built-in diagnostics (e.g., communication fault detection, protocol mismatch alerts) to monitor link health and trigger real-time notifications for proactive maintenance, while its rugged design (with electromagnetic interference shielding and wide operating temperature range) ensures stable performance in harsh industrial settings like oil & gas refineries, chemical plants, and power generation facilities.
