Description
Product Overview
The ABB PM825 3BSE010796R1 is the processor module used in ABB’s Advant Controller 80 (AC 80) automation platform. Its core hardware is based on an MC68360 microprocessor operating at 25 MHz, with dedicated memory for system and user programs. Available technical documentation specifies 1 MB of system Flash PROM, 512 KB of user application Flash PROM, and 1 MB of RAM for execution of system and user programs. The AC 80 can operate as a stand-alone controller or participate in an AF 100 (Advant Fieldbus 100) network, making the processor central to both local control and distributed system communication.
For ABB PM825 3BSE010796R1, procurement terminology can be confusing because ABB’s product database describes the catalog item as “PM825; PM825 S800 Processor,” while technical documentation identifies the hardware as the AC80 processor. ABB currently marks 3BSE010796R1 as no longer for sale and lists replacement product 42000052. This makes the original part number particularly relevant for maintaining installed legacy equipment where an exact hardware match is preferred over a broader modernization project.
The ABB PM825 3BSE010796R1 also supports the AC80’s established interface environment, including AF 100 networking and user interfaces such as DriveWindow and Modbus-based panels. A spare should therefore be evaluated against the existing AC80 application, firmware/software package, AF 100 topology, and connected equipment—not merely against the processor board itself. The module also uses a lithium battery, which is worth checking on any long-stored surplus unit.
Product Introduction
Replacing an AC80 processor is rarely just a matter of matching the catalog number. PM825 combines a 25 MHz MC68360 processor with 1 MB system Flash, 512 KB user Flash, and 1 MB RAM, while supporting the AC80’s AF 100 communication architecture.
For an ABB AC80 legacy replacement, preserve the existing application and software environment before changing the processor. ABB now lists 3BSE010796R1 as discontinued, with 42000052 shown as the replacement product.

Frequently Asked Questions
What is ABB 3BSE010796R1 used for?
The is the processor module for ABB’s controller. It executes system and user application programs and provides the processing platform for local control and AF 100 network communication.
The can operate:
- As a stand-alone controller
- As an AF 100 network node
- With drive-related interfaces
- With Modbus-based operator equipment
- Within a larger Advant control architecture
Is the same as an S800 processor?
ABB’s current product database describes 3BSE010796R1 as “; S800 Processor,” while other ABB technical information identifies as the processor.
For procurement, retain the exact / 3BSE010796R1 identification. Do not substitute another S800-family processor merely because it uses similar terminology.
What processor does use?
The processor is based on an MC68360 microprocessor running at 25 MHz. Its documented memory architecture includes 1 MB system Flash PROM, 512 KB user application Flash PROM, and 1 MB RAM.
Those figures are important when comparing the original hardware with later replacement products. A replacement number should be validated against the installed software environment.
Is ABB 3BSE010796R1 discontinued?
Yes. ABB’s current product record states that 3BSE010796R1 is no longer for sale and identifies 42000052 as its replacement.
For a plant with an established installation, the decision between an exact legacy spare and the ABB replacement should be based on software compatibility, cabinet arrangement, fieldbus architecture, and maintenance strategy.
Does support AF 100?
Yes. The can operate as part of an AF 100 network, and the provides the processing platform for that controller architecture.
When replacing a processor in an operating AF 100 system, verify:
- Node configuration.
- AF 100 connection.
- Application software.
- Controller firmware.
- Connected I/O and drive configuration.
- Operator-interface communication.
Does contain a battery?
Yes. ABB’s product information identifies a lithium battery, and the ordering information identifies 4943013-6 as the spare battery.
For a surplus processor that has been stored for years, battery age should be part of the incoming inspection. Do not assume that an unused unit has a healthy battery.
Can I replace without losing my logic?
The processor contains memory for the system and user application programs, but a replacement processor should not be assumed to contain the application’s current configuration.
Before removing the existing unit, preserve:
- application program
- System software/firmware information
- AF 100 configuration
- Drive parameters
- Modbus configuration
- Controller settings
- Battery condition
- Existing diagnostic information
The available ABB ordering information specifically notes that the is supplied without the system software program included, which is an important procurement detail.
Can I hot-swap ?
Do not assume hot-swapping is permissible.
The is the processor of the controller, so removing it can affect control execution and communications. The correct procedure depends on the cabinet, application state, redundancy or process arrangement, and approved maintenance procedure. For a live plant, place the controller/process in the required maintenance state before removing the processor.
How should a New Surplus be tested?
For this legacy processor, a visual inspection is not enough.
Recommended acceptance procedure:
- Verify / 3BSE010796R1 markings.
- Record hardware revision and serial number.
- Inspect the processor board and connectors.
- Check the lithium battery condition.
- Verify the correct power connector.
- Verify the AF 100 connector.
- Install the processor in a compatible test environment.
- Confirm normal startup diagnostics.
- Verify system software/firmware identification.
- Load a controlled test application.
- Verify application execution.
- Test AF 100 communication where applicable.
- Check DriveWindow/Modbus communication if required.
- Cycle power and confirm retained configuration.
- Record all diagnostic and communication results.
Procurement note: ABB’s own current record is clear that 3BSE010796R1 is no longer for sale and has been replaced by 42000052. For an existing plant, however, an exact spare may still be the more practical maintenance choice when minimizing architectural change is the priority.
