Honeywell CC-PCF901 51405047-176 FTE Control Firewall Module

Overview

The Honeywell CC-PCF901 (51405047-176) is a 9-port Fault Tolerant Ethernet (FTE) Control Firewall Module designed for Experion PKS Series C networks. Acting as the secure communications center (CF9), it ensures critical network security inside the control cabinet by discarding non-essential Ethernet traffic and protecting the C300 controller domain from unauthorized network access or saturation failures.

Compatible Termination Assembly (IOTA)

• CF9 IOTA (Control Firewall 9-Port Assembly): The module mounts and plugs directly onto the specialized CF9 IOTA backplane to distribute power and interface the 9 Fault Tolerant Ethernet ports.

Key Security & Communication Features

• FTE Packet Filtering: Rejects and filters out all inbound standard Ethernet broadcast/multicast messages not explicitly required for process control execution.
• Traffic Prioritization: Automatically prioritizes data streams on the downlink ports over ingress traffic entering through the uplink network port if the communication fabric approaches saturation.
• C300 Domain Protection: Validates protocol signatures to ensure only C300-compliant messages pass into the operational control layer.
• FTE Distribution: Provides localized, high-efficiency distribution of Fault Tolerant Ethernet links to multiple Series C FIMs (Fieldbus Interface Modules), C300 controllers, and intra-cabinet nodes.

LED Diagnostics Indicators

• Power LED: Steady green when primary 24 V DC input power is safely applied via the IOTA rail.
• Status LED: Illuminates Red during the initial Power-On Self-Test (POST); turns Green for normal system health; blinks Green to indicate active data traffic on connected internal nodes.
• Downlink/Uplink Port LEDs: Displays Green when a reliable hardware link is present; flashes Green with ongoing packet traffic; flashes Red if too many unauthorized devices are detected on the link slot.

Installation Notes

• Plug the CC-PCF901 module straight onto its matched slots on the CF9 Input/Output Termination Assembly (IOTA) inside the Series C cabinet.
• Verify that the 8 localized downlink ports are dedicated to intra-cabinet routing (C300s, FIMs) while the single uplink port connects back toward the main switch layers.
• Ensure that your twisted-pair copper cable drops do not exceed standard industrial length limits and remain anchored away from heavy high-voltage components to maintain noise margins.
