Product Overview

The Honeywell CC-TCF901, part number 51308301-175, is a mission-critical security and communication arbitration module designed for the Experion PKS Series C architecture. This Control Firewall acts as a specialized bridge between the FTE (Fault Tolerant Ethernet) network and the Series C C300 controllers, shielding the control level from broadcast storms and unauthorized network traffic. By providing a hardware-based security perimeter, the CC-TCF901 ensures that safety-critical data reaches the logic solver without latency or interference. It is an essential component for maintaining the integrity of the Pepperlink communication interface, ensuring that the control system operates within a deterministic and secure environment.

Strategic Industrial Security Deployments

This Control Firewall module is indispensable for facilities that prioritize cybersecurity and network stability as part of their functional safety strategy.

• Refining and Volatile Processing: Protecting the communication backbone of Emergency Shutdown Systems (ESD) from external network disruptions or data congestion.

• Large-Scale Power Utilities: Ensuring stable data synchronization between distributed turbine controllers and the central DCS in electrically noisy environments.

• Chemical Plant Safety Loops: Maintaining clean, high-speed data paths for Safety Instrumented Systems (SIS) where deterministic response times are required.

• Offshore Asset Protection: Providing a ruggedized security interface for remote drilling platforms where localized network stability is critical for operational uptime.

• System Expansion Security: Acting as the primary security gateway when integrating new C300 controller nodes into an existing industrial Ethernet backbone.
