Product Overview

The Honeywell CC-TCF901 serves as a high-performance 9-Port Control Firewall Input Output Termination Assembly (IOTA) within the Experion PKS architecture. This 100% brand-new, original hardware provides a secure communication interface for in-cabinet controllers and Series C Field Interface Modules (CFIMs). By isolating control traffic and managing Fault Tolerant Ethernet (FTE) connections, the CC-TCF901 ensures deterministic signal flow and prevents unauthorized network interference from compromising critical process loops.

Technical Specifications

The CC-TCF901 combines Ethernet switching capability with integrated power distribution to streamline cabinet wiring.

Engineering Advantages

The Honeywell CC-TCF901 delivers specialized networking and security benefits for DCS engineers:

• FTE Network Integrity: The module provides eight dedicated ports for FTE cables, while the ninth port acts as a high-priority uplink to the supervisory network. This architecture ensures that local control traffic remains separated from broader plant network traffic, maintaining high system availability.

• Integrated Power Management: The IOTA distributes 24V DC power directly to the control components through the mounting base. Consequently, this design reduces the need for auxiliary terminal blocks and simplifies the overall power distribution scheme within the Series C cabinet.

• Flexible Media Conversion: While the base unit features RJ-45 connections, the architecture supports optional Single-Mode (Ca-FSMx01) or Multi-Mode (Ca-FMMx01) fiber modules. This allows engineers to extend control networks over long distances without risking electromagnetic interference.

• Cybersecurity Hardening: By functioning as a hardware-level firewall, the CC-TCF901 restricts traffic to authorized Experion protocols. It actively protects the controller from network storms and unwanted data packets that could lead to CPU saturation or unexpected process trips.

FAQs

• Can I use the CC-TCF901 with fiber optic cables?

  Yes. While the standard board features RJ-45 ports, you can install the Ca-FSMx01 Single-Mode or Ca-FMMx01 Multi-Mode fiber modules to facilitate long-range FTE communication and eliminate electrical noise risks.

• What is the function of the 9th port?

  The 9th port serves specifically as the uplink to the Fault Tolerant Ethernet (FTE) supervisory network. It aggregates data from the eight local device ports and transmits it to the higher-level DCS architecture.

• Does this unit require a separate power supply for the connected controllers?

  The CC-TCF901 facilitates 24V DC distribution to the control modules attached to it. However, you must still provide a stable 24V DC source to the IOTA board itself to enable this distribution functionality.

• Is the CC-TCF901 compatible with CC-TUIO31 modules?

  The CC-TCF901 is the termination assembly (IOTA) used to provide the network and power infrastructure. It often works in conjunction with various Series C modules like the CC-TUIO31 to ensure they have the necessary network access and power to function within the Experion PKS system.
