Note: Some aftermarket sources describe PM665 as an AC800M communication module, but distributor and supplier listings identify 3BDS005799R1 as an Advant OCS / Advant Controller processor module. Because public datasheet information is limited, always confirm the nameplate, rack type, and firmware compatibility before replacement.
Product Introduction
The ABB PM665 (3BDS005799R1) is a processor module for the ABB Advant OCS platform, commonly associated with the Advant Controller 110 / 160 family. It functions as a central processing unit within Advant OCS stations, executing control logic, managing I/O communication, and supporting fieldbus integration for process automation applications.
The module is built around a PowerPC-based processor and includes features such as an integrated redundancy voter, high-speed communication links, and speed input capability. It supports industrial communication protocols including Profibus DP and Modbus, allowing integration into existing Advant OCS networks and connection with external devices.
For MRO buyers and system integrators maintaining legacy ABB DCS installations, PM665 is typically replaced when an Advant Controller station experiences CPU faults, communication loss, redundancy errors, or when spare coverage is required for aging Advant OCS infrastructure. Because Advant OCS is a legacy platform, correct identification is essential. The order code 3BDS005799R1 should be matched exactly, and compatibility with the existing rack, I/O modules, and system software must be verified before commissioning.
QA & Testing SOP
- Nameplate verification — Confirm PM665 and full order code 3BDS005799R1.
- Visual inspection — Check the module housing, connectors, PCB, and status indicators for damage or corrosion.
- Connector inspection — Verify backplane and front connectors are clean and undamaged.
- Power-on test — Install into a compatible Advant Controller rack and verify normal LED status.
- Communication check — Confirm communication with the engineering workstation and connected fieldbus nodes.
- Application verification — Verify existing program download, online monitoring, and fault-free operation.
- Redundancy check — If configured for redundancy, verify switchover behavior per system design.
All units ship in anti-static packaging. A test log can be provided on request when rack testing is available.
Installation Pitfalls & Guide
Confirm Advant OCS platform. PM665 3BDS005799R1 belongs to the Advant Controller family within Advant OCS. It is not an AC800M CPU, AC500 PLC, or System 800xA controller.
Verify the exact order code. Some listings may describe PM665 generically. Always confirm 3BDS005799R1 against the existing module nameplate.
Check system software compatibility. This module is associated with System Software Base SW 2.2 3BDS005572R7. Firmware and software version mismatches may prevent program download or cause communication faults.
Do not substitute with other PM modules. PM665 is not interchangeable with PM510, PM511, PM645, PM810, or AC800M processors without a full compatibility review.
Back up before replacement. Save the existing control application, configuration, and parameter set before removing the faulty module.
Handle as ESD-sensitive equipment. Use anti-static packaging and avoid touching connectors or PCB components.
Replacement steps:
- Back up the control application and record current alarms.
- Power down the rack if required by site procedure.
- Remove the faulty PM665 and label all connections.
- Install the replacement module and verify seating.
- Power up and check status LEDs.
- Verify communication, load the application, and confirm stable operation.
Technical FAQ
Is PM665 3BDS005799R1 an AC800M module? Some aftermarket descriptions list it as AC800M-related, but distributor references identify it as an Advant OCS / Advant Controller processor module. Confirm against the nameplate and rack type before use.
Which controller family does it belong to? It is associated with the Advant Controller 110 / 160 family within the Advant OCS platform.
Does it support redundancy? Yes. The module includes an integrated redundancy voter and supports hardware redundancy configurations.
What communication protocols does it support? It supports Profibus DP and Modbus communication, with rates from 9.6 kbps to 12 Mbps.
Is this product still in production? Advant OCS is a legacy platform. Availability is typically through surplus, refurbished, or remaining OEM stock. Confirm condition and warranty before purchase.
Do you stock single units? Yes. Single units are available for MRO replacement; multi-unit spares and project support can be quoted on request.
