Honeywell CC-TAON01 51306519-175 Migration-Ready AO Module

Overview

Honeywell CC-TAON01 51306519-175 Migration-Ready AO Module: Legacy System Migration and Compatible Upgrade

The Honeywell CC-TAON01 (part number 51306519-175) is a C300 Series analog output module designed for the Experion PKS distributed control system platform. As industrial facilities accelerate the retirement of TDC 3000, PlantScape, and early-generation Experion R100/R200 controllers, the CC-TAON01 has become a critical component in structured migration projects — providing a verified drop-in replacement path that preserves existing field wiring, terminal block layouts, and 4-20mA loop configurations without requiring panel redesign or extensive re-engineering.

This module delivers 8-channel isolated analog output at 4-20mA resolution, compatible with the C300 Controller and CIOM-A chassis backplane. During migration from legacy TDC 3000 HPM or PM I/O subsystems, engineers must verify that the existing SCADA tag database, Experion Control Builder function blocks, and HMI graphic displays are mapped correctly to the new module address. The CC-TAON01 supports standard FTE (Fault Tolerant Ethernet) communication architecture, which simplifies integration into existing Experion R400 and R500 network topologies without requiring additional protocol converters or communication bridges.

Retrofit Planning for Existing Automation Systems

A successful CC-TAON01 retrofit begins well before the physical module swap. Project engineers should first audit the existing C300 Controller (CC-PCF901) configuration to confirm available chassis slots and backplane power budget. In systems where the original CIOM-A chassis is fully populated, adding the CC-TAON01 may require installing an additional C300 I/O Link Extender or expanding to a secondary chassis — a step that must be reflected in the updated network topology diagram and FTE switch port allocation.

Field wiring continuity is the next critical checkpoint. The CC-TAON01 uses the standard Honeywell LLMUX terminal block interface, and in most TDC 3000 to Experion migrations, a CC-TAIX01 terminal assembly is used to bridge legacy marshalling panel wiring to the new module without re-pulling field cables. Engineers should verify that each 4-20mA output loop is correctly terminated, that loop power sources are isolated, and that any existing signal isolators or barriers in the marshalling cabinet remain compatible with the new output impedance characteristics.

On the software side, the Control Builder CM (Control Module) for each replaced AO point must be downloaded to the C300 Controller after the physical swap. This process requires a coordinated outage window — typically 15 to 30 minutes per controller segment — during which the affected output channels will be in a safe-state hold condition. If the facility uses a Honeywell Experion HMI Station with custom graphic displays, each AO tag reference must be verified against the updated module address to prevent display mismatches or alarm suppression errors. Where Modbus RTU or HART pass-through communication was previously configured on legacy AO modules, the CC-TAON01’s HART-capable channels should be re-commissioned using the Field Device Manager (FDM) to restore instrument diagnostics and calibration data.

Downtime Control During System Migration

Minimizing unplanned downtime is the primary operational constraint in any live-plant DCS migration. For CC-TAON01 installations, the recommended approach is a phased hot-swap strategy: replace one chassis segment at a time while keeping adjacent control loops in manual mode at the DCS operator station. Before pulling the legacy module, operators should confirm that all affected AO channels are set to manual output at their last known process value, preventing sudden valve or actuator movement during the swap interval.

Program logic preservation is equally important. The existing Control Builder CM backup — including all PID tuning parameters, output scaling factors, and interlock logic — must be archived before any hardware change. After the CC-TAON01 is seated and the CM is downloaded, a point-by-point output verification test should be performed: drive each channel to 4mA, 12mA, and 20mA in sequence and confirm the corresponding field instrument response at the marshalling panel. This functional test, combined with a 30-minute steady-state observation period, provides confidence that the replacement module is performing within specification before returning the loops to automatic control.

For facilities with redundant C300 Controllers, the migration can be executed with zero process interruption by performing the module swap on the standby controller first, verifying operation, then executing a controlled switchover before repeating the process on the primary controller. This approach is strongly recommended for critical process units where continuous output is a safety or production requirement.

Retrofit Support FAQ

Q1: Is the CC-TAON01 51306519-175 a direct replacement for TDC 3000 HPM analog output modules?
A: The CC-TAON01 is the Experion PKS C300 platform equivalent for legacy TDC 3000 HPM AO functions. It is not a plug-and-play physical replacement — a terminal block adapter (CC-TAIX01 or equivalent) and a Control Builder CM download are required. However, existing field wiring and 4-20mA loop configurations can typically be reused without modification.

Q2: What firmware version is required on the C300 Controller before installing the CC-TAON01?
A: Honeywell recommends Experion PKS R400.2 or later for full CC-TAON01 feature support, including HART pass-through and advanced diagnostics. Controllers running R300.x or earlier should be upgraded prior to module commissioning to avoid compatibility issues with the FTE communication stack.

Q3: Does the CC-TAON01 ship pre-tested, and what does the support terms confirmed by quotation cover?
A: Yes. Each CC-TAON01 unit is functionally tested prior to shipment, including channel-by-channel output verification and backplane communication checks. The support terms confirmed by quotation cover manufacturing defects and DOA (dead-on-arrival) failures from the date of shipment. Support terms service includes priority replacement dispatch to minimize site downtime.

Q4: What is the typical lead time and stock availability for the CC-TAON01 51306519-175?
A: Stock is maintained for immediate dispatch. Standard orders ship within 1-3 business days. For urgent migration projects or bulk retrofit orders, expedited shipping and dedicated inventory reservation are available — contact our team directly to confirm current stock levels and delivery commitments.
