Hardware Specifications

Honeywell Process Control & DCS Connectivity

The CC-TCF901 implements network traffic filtering to enforce security boundaries within Honeywell control systems. It utilizes channel-to-channel isolation to prevent potential electrical noise or network congestion from propagating across DCS control segments. The module supports high-speed data packet routing, maintaining timing precision required for real-time control loops. By managing the flow of industrial protocols, the module minimizes latency on critical control buses, ensuring that time-sensitive data remains synchronized across the system architecture.

Frequently Asked Questions

Q: Does the CC-TCF901 require separate power supply wiring from the I/O rack?

A: No, the module receives operating power directly from the backplane of the compatible DCS chassis. Verify the rack power supply capacity before installation to ensure sufficient current for the module.

Q: Is this module compatible with standard TCP/IP networking equipment?

A: The module is designed for Honeywell DCS network integration. While it interfaces with Ethernet-based media, the protocol filtering is specific to Honeywell communication standards. Direct connection to general-purpose office networking switches is not recommended without proper system integration guidelines.

Q: Can the firewall rules be modified on this module?

A: Security policies and firewall configurations are managed via the DCS engineering station software. The module itself acts as an execution device for these policies and does not host a local user-configurable interface for rule modification.

Field Installation Guidelines

• Ensure the host DCS rack is powered down before inserting the CC-TCF901 module into the designated slot.
• Check that all backplane connectors are free of debris to prevent poor contact and signal degradation.
• Slide the module along the guide rails until it is fully seated, then tighten the retaining screws to ensure proper grounding to the chassis.
• Use Category 6 or higher shielded twisted-pair cabling for Ethernet connections to minimize electromagnetic interference.
• Verify the network link status via the system diagnostic LEDs after power-up.
