CC-TPOX01 51306528-175 PROFIBUS DP Gateway Module | Honeywell

The Honeywell CC-TPOX01 51306528-175, also cataloged as the CC-TPOX01 PROFIBUS Gateway Module, operates as a dedicated hardware component for protocol translation and field bus data acquisition within Honeywell Experion DCS networks. It translates PROFIBUS DP device profiles and cyclic process variables directly into the internal control backplane structure.

Hardware Specifications

PROFIBUS DP Fieldbus Integration & Network Determinism

The Honeywell CC-TPOX01 gateway module maintains high-speed master-slave protocol conversion between field-level PROFIBUS DP network segments and the Honeywell Experion DCS backplane. The internal communication processor manages cyclic I/O data exchanges while isolating physical RS-485 transceiver lines from logic power rails. Galvanic channel-to-system isolation minimizes common-mode voltage disruptions across extended fieldbus cable runs, preserving signal integrity when interfacing smart actuators, drives, and distributed I/O nodes.

Frequently Asked Questions

Q: Can the CC-TPOX01 gateway module be hot-swapped during active system operation?

A: Yes, live insertion and removal are supported on the Series 8 baseplate platform without interrupting power or data traffic to neighboring gateway or controller slots.

Q: How is PROFIBUS DP bus termination handled at the gateway module terminals?

A: Fieldbus line termination must be applied at both physical ends of the RS-485 segment using active PROFIBUS DP termination networks or switchable DB9/screw terminal connectors.

Q: What mechanisms prevent ground potential differences from affecting the internal backplane logic?

A: Integrated galvanic isolation barriers electrically separate the field-side PROFIBUS DP transceiver hardware from the internal system processing circuitry.

Field Installation Guidelines

1. Mount the CC-TPOX01 module firmly on the standard 35 mm DIN rail or panel surface within the enclosure.
2. Verify that the shield drain wire of the PROFIBUS DP cable is connected to a low-impedance ground bus bar near the cabinet entry point.
3. Plug the PROFIBUS connector securely into the interface port and tighten the retaining screws to ensure continuous shielding contact.
4. Set the correct RS-485 line termination switches to ON only if the module represents the physical end node of the PROFIBUS segment.
5. Maintain strict physical separation between PROFIBUS communication cables and high-voltage AC power wiring inside wire ducts.
