CC-TCF901 | Honeywell | FTE Network Control Firewall

Product Overview

The Honeywell CC-TCF901 functions as the primary security and connectivity hub for the Experion PKS Series C architecture. This 9-Port Control Firewall IOTA (I/O Termination Assembly) provides the physical interface for the Fault Tolerant Ethernet (FTE) bridge, shielding the C300 controller and associated Series C Fieldbus Interface Modules (CFIMs) from network-borne traffic congestion. By regulating data flow between the supervisory network and the local control level, the CC-TCF901 maintains the deterministic performance required for high-speed process automation. We offer this unit as 100% Brand New original equipment to ensure maximum system authoritativeness and protection.

Engineering Advantages

• Deterministic Network Traffic: The CC-TCF901 hardware-limits broadcast and multicast traffic. This prevents "broadcast storms" on the plant network from impacting the execution of critical control loops within the C300 processor.

• Integrated Power Distribution: This IOTA distributes 24 VDC power directly to the mounted control modules, eliminating redundant wiring and simplifying the internal cabinet layout.

• Seamless FTE Integration: The 9th port acts as a dedicated uplink to the FTE supervisory network, ensuring the controller remains visible to the Global User Station (GUS) while isolated from non-essential traffic.

• Media Flexibility: Through the use of optional Ca-FSMx01 or Ca-FMMx01 modules, engineers can extend the FTE network over long distances using fiber optics, bypassing the distance limitations of standard copper RJ-45 cabling in large-scale refinery or offshore applications.

FAQs

• Can the CC-TCF901 be used as a standard Ethernet switch?No. The CC-TCF901 is a specialized Control Firewall designed specifically for Honeywell's proprietary FTE protocol. It uses embedded logic to prioritize control data, which a standard commercial switch cannot replicate.

• Does the IOTA require a separate power supply for the firewall module?The IOTA receives 24 VDC and distributes it to the firewall module and local controller. Ensure your power system meets the 0.30mA supply rating to maintain stable network links.

• How does this module handle redundancy?In a standard Experion PKS setup, you install two CC-TCF901 IOTAs (Yellow and Green networks) to provide a fully Fault Tolerant Ethernet environment, ensuring no single point of network failure.
