Description
Product Overview
The ABB PM665 3BDS005799R1 is a PowerPC-based processor module for ABB Advant automation systems. It is designed for controller configurations where processing redundancy and high-speed system communication are important.
ABB identifies the PM665 as a processor module with an integrated redundancy voter, high-speed link, and rotational speed input. It is used with the Advant Controller 160 platform and can participate in dual- or triple-redundant processor configurations.
The redundancy capability makes the PM665 particularly useful in control applications where a processor failure should not immediately interrupt the process. In a dual-redundant arrangement, an additional PM665 is required; triple redundancy uses additional processor modules in the appropriate controller stations.

ABB’s product identification describes the PM665 specifically as a PowerPC-based processor with redundancy voter, high-speed link and speed input. It should not be confused with visually similar ABB processor modules having different hardware functions.
Processor and Redundancy Function
The PM665 acts as the central processing element of the controller. It executes the configured control application and coordinates data exchange with the controller’s communication interfaces and I/O architecture.
For redundancy, the voter function is important. The controller can compare processor operation and manage the transition between redundant processor units according to the configured architecture.
A typical redundant arrangement can be represented as:
PM665 Primary → Redundancy Voter → Controller Processing
PM665 Secondary → Redundancy Voter → Standby / Redundant Processing
For higher availability, the Advant Controller 160 architecture also supports triple-redundant configurations using additional processor modules.
Advant Controller 160 Compatibility
The PM665 belongs to the Advant Controller 160 processor family. ABB documentation lists PM640, PM644, PM645, PM646 and PM665 as processor options for the platform, with the PM665 providing redundancy capability and a rotational-speed input.
When replacing a processor, check:
- Existing processor model
- Complete ABB order number
- Controller 160 subrack configuration
- Redundancy arrangement
- Communication interface modules
- Application software/configuration
- Firmware compatibility
- Speed-input requirements
A PM665 should not be substituted solely because another ABB processor has the same physical form factor.
Installation & Replacement Guide
Before installation, shut down or isolate the relevant equipment according to the plant’s approved maintenance procedure.
- Record the complete part number and revision.
- Photograph the installed PM665 and surrounding modules.
- Record the processor’s slot position.
- Confirm whether the controller uses single, dual, or triple redundancy.
- Verify the associated communication interface configuration.
- Remove the existing module using the approved extraction procedure.
- Inspect the backplane connector for bent or contaminated contacts.
- Install the replacement PM665 carefully.
- Confirm that the module is properly seated.
- Restore the controller according to the system startup procedure.
- Check processor status and redundancy diagnostics.
- Confirm communication with the controller and connected I/O stations.
ABB documentation for the Advant Controller 160 states that modules can be replaced while the system is operating, but this should only be performed when the complete system configuration and maintenance procedure explicitly permit live replacement.
Inspection Before Installation
For a replacement or surplus PM665, inspect:
- ABB identification label
- 3BDS005799R1 order number
- Revision information
- Front-panel condition
- Connector pins
- PCB condition
- Mounting mechanism
- Signs of oxidation or corrosion
- Evidence of overheating
- Foreign material or contamination
For long-term spare storage, use ESD protection and keep the module in a clean, dry, temperature-controlled environment.
Troubleshooting
Processor Does Not Start
Check the controller power supply, module seating, backplane connection and processor status indicators. If the hardware is correct but the controller remains unavailable, check the system configuration and processor compatibility.
Redundancy Fault
Verify that the two processor modules have the correct model and compatible configuration. Check the redundancy link and controller diagnostics.
Speed Input Problem
Because PM665 includes a rotational speed input, inspect the associated speed signal wiring and configuration when the controller reports a speed-input fault. Confirm that the field signal matches the original system design.
Communication Failure
Check the associated communication interface modules and controller configuration. The PM665 should be evaluated as part of the complete Advant Controller 160 station rather than as an isolated processor.
Maintenance Recommendations
For critical ABB Advant installations:
- Keep at least one tested processor spare available.
- Record the complete ABB order number and revision.
- Maintain a backup of the controller configuration.
- Check redundancy status during scheduled maintenance.
- Inspect backplane connectors during planned shutdowns.
- Keep spare modules in ESD-safe packaging.
- Record processor replacement history.
For obsolete or long-running Advant installations, maintaining a verified spare can be particularly useful because processor availability and system lifecycle become procurement concerns.
Application Scenarios
The PM665 can be used in:
- Process automation
- Industrial control systems
- ABB Advant Controller 160 installations
- Redundant controller architectures
- Turbine-related control applications
- Continuous production processes
- Power and utility automation
- Legacy DCS maintenance
- Critical control-system spare inventories
The integrated speed input also makes the PM665 suitable for controller configurations where rotational-speed information forms part of the control application.
FAQ
Q: What is ABB PM665 3BDS005799R1?
A: It is a PowerPC-based ABB processor module for the Advant Controller 160 system, with an integrated redundancy voter, high-speed link and rotational speed input.
Q: Does PM665 support processor redundancy?
A: Yes. ABB documentation describes PM665 as supporting dual- or triple-redundant processing when the appropriate additional processor modules and system configuration are used.
