Honeywell TC-CCN014 Redundant Network Interface Module

The Honeywell TC-CCN014, also cataloged as the TC-CCN014 Network Interface Modules, operates as a dedicated hardware component for high-availability node communication and control traffic bridging within Honeywell Experion PKS platforms.

Hardware Specifications

Redundant Channel Isolation & FOUNDATION Fieldbus / Profibus PA Connectivity

The TC-CCN014 provides dual Ethernet ports and redundant Fieldbus channels to maintain uninterrupted network routing across Experion PKS DCS platforms. Designed to interface directly with FOUNDATION Fieldbus / Profibus PA connectivity, Modbus, and Ethernet/IP protocols, the module features onboard microprocessor-driven signal routing that insulates internal system logic from field-side interference. Internal channel-to-channel isolation circuits prevent circulating ground loop currents across redundant communication paths, preserving deterministic frame delivery during primary link failover events.

Frequently Asked Questions

Q: Does replacing a TC-CCN014 module interrupt field bus communications across the secondary port?

A: In a redundant configuration, the standby communication path assumes active traffic management automatically without packet loss when the primary TC-CCN014 module is unseated.

Q: How is non-volatile data preserved on the TC-CCN014 during a primary 24 VDC power interruption?

A: Onboard EEPROM and Flash storage maintain node addresses, network configuration tables, and historical log parameters without requiring external battery backup.

Q: Can the TC-CCN014 be hot-swapped while the backplane rack is energized?

A: Removal and insertion under power are permitted provided the backplane chassis supports live module replacement and local cabinet safety protocols are observed.

Field Installation Guidelines

1. Seat the TC-CCN014 module into the target chassis slot until the mechanical locking levers fully snap into position.
2. Connect dual primary and secondary Ethernet communication cables to the front panel ports to establish full network redundancy.
3. Route fieldbus communication cables away from high-voltage motor leads and AC power distribution wiring to prevent inductive noise coupling.
4. Ensure the cable shield drain wires are tied directly to the cabinet earth ground terminal block at a single point prior to energizing the 24 VDC supply line.
