Honeywell CC-PCF901 Experion Series C Control Firewall Module

The Honeywell CC-PCF901, also cataloged as the CC-PCF901 Control Firewall Module, operates as a dedicated hardware component for network traffic filtering and security segmentation within Honeywell Experion Series C I/O Mark II networks.

Hardware Specifications

Process Network Isolation & Access Control Filtering

The CC-PCF901 firewall module establishes hardware-level network segmentation between critical control nodes and supervisory networks within the Experion Series C environment. Designed to maintain signal throughput for process instruments operating over 4-20 mA HART loop protocol interfaces and upper-level DCS backplanes, the unit inspects real-time Ethernet traffic. Its internal filtering architecture enforces strict access control policies, preventing unauthorized network queries from interfering with deterministic real-time control communications.

Frequently Asked Questions

Q: Can the CC-PCF901 module be hot-swapped within the Experion Series C rack during live operation?

A: Removal or replacement of the module must follow Series C redundant system procedures; swapping an active firewall in a non-redundant configuration disrupts upstream network communications to connected controllers.

Q: How does the CC-PCF901 handle unexpected broadcast storms on field network ports?

A: The internal firewall logic applies rate-limiting and real-time traffic monitoring across its 8 Ethernet access ports to block broadcast storms from impacting the central processing uplink.

Q: Is external configuration software required to establish filtering rules on the CC-PCF901?

A: Security policies and access control lists are defined and loaded directly through the Experion PKS system engineering environment.

Field Installation Guidelines

1. Mount the CC-PCF901 securely onto the standard DIN rail or panel surface within the control enclosure.
2. Connect a dedicated protective grounding wire from the module ground terminal to the main cabinet earth bar to ensure transient voltage dissipation.
3. Insert RJ45 Ethernet network cables into the 8 access ports and single uplink port, ensuring cable bend radiuses do not exceed cable manufacturer limits.
4. Verify link status LEDs on each connected port prior to commissioning network traffic filtering rules in the control system software.
