• Full Model Number: IMMFP03
• Lifecycle Status: Legacy / mature INFI 90 component

• Top 3 Technical Specs: 32-bit CPU; 32 MHz; 2 MB SRAM
• Stock & Condition: New Surplus / Tested Refurbished; physical stock confirmed before shipment

Module 3: Supply Chain & Technical Deep Dive

When an older INFI 90 control system loses its MFP processor, finding the exact board can become the real outage constraint. ABB Bailey IMMFP03 is a Multi-Function Processor Module for the INFI 90 system. It can execute analog, sequential, batch, and other process-control applications while communicating with I/O modules through the INFI 90 architecture. The original documentation states that one MFP can communicate with up to 64 I/O modules, depending on the system configuration.

For inventory planning, this is an insurance spare rather than a routine consumption item. The documented hardware uses a 32-bit processor at 32 MHz, with 2 MB total SRAM, 512 KB NVRAM, and 512 KB ROM. Power input is +5 VDC at 2 A, with typical dissipation of 10 W. A single tested spare can therefore reduce the exposure created by long sourcing cycles for legacy control hardware. Before purchase, confirm whether the installed system specifically requires IMMFP03 or the higher-memory IMMFP03B variant.

Module 4: Migration, Compatibility & Field Traps

Replacement Matrix

⚠️ Field Trap 1 — IMMFP03 vs IMMFP03B

Do not confuse the two variants.

The original provides 2 MB SRAM, while IMMFP03B provides 8 MB SRAM. Their NVRAM capacities also differ: 512 KB for versus 2 MB for IMMFP03B.

If the plant BOM calls for , match the exact hardware requirement rather than assuming the larger-memory variant is automatically acceptable.

⚠️ Field Trap 2 — Redundant MFP Configuration

The INFI 90 architecture supports redundant MFP operation. A backup processor can remain in standby while the primary controls the process.

Before replacing a redundant unit, record the primary/backup configuration and firmware revision. The replacement should be configured to the same system requirements before failover is tested.

Module 5: Quality Assurance & Testing SOP

Legacy processor boards need a stricter receiving process. A clean faceplate is not enough.

1. OEM Identification Inspection

• Verify ABB Bailey identification.
• Confirm marking.
• Record serial number and hardware revision.
• Inspect the PCB for corrosion.
• Check edge connectors and mounting points.
• Look for cracked components, discoloration, or repair traces.
• Compare the board against an approved reference unit.

2. Power-On Self-Test

Using a compatible INFI 90 test environment:

• Apply the specified +5 VDC supply.
• Check startup behavior.
• Monitor module status LEDs.
• Verify processor operation.
• Check for machine-fault indications.
• Record abnormal current consumption.
• Observe operating temperature during the test.

The manufacturer documentation specifies +5 VDC at 2 A and approximately 10 W typical power dissipation.

3. Communication Test

Where the test configuration supports it:

• Verify module-bus communication.
• Check the I/O expander bus.
• Test the redundancy link.
• Verify communication with configured I/O modules.
• Confirm the processor is recognized by the INFI 90 system.

The can use an optional IMMPI01 Multi-Function Processor Interface Module for serial communications and station-link functions.

4. Control Function Test

Load an approved test configuration and verify:

• Function-block execution
• Control logic operation
• I/O data exchange
• Processor diagnostics
• Redundancy behavior where configured
• Application stability during extended operation

5. Final QC

• Part number recorded
• Serial number recorded
• Hardware revision recorded
• Memory configuration verified
• Power-on test completed
• Communication test completed
• ESD bag sealed
• Protective packaging installed
• QC report archived
• Shipment photographs retained

Module 6: Procurement-Driven FAQ

1. Is ABB physically in stock, and when can it ship?

Physical inventory should be confirmed against the actual board before a delivery commitment is made. For an emergency INFI 90 replacement, confirm quantity, condition, test status, and carrier cutoff at the time of quotation.

2. How do you verify an obsolete surplus unit?

The inspection should begin with the OEM label and serial number, followed by PCB and connector inspection. A compatible test rack should then be used for power-up, diagnostics, communication, and application testing.

For a tested unit, request the actual test report and product photographs.

3. What warranty applies to a tested surplus processor?

The warranty period and return procedure should be stated in the commercial quotation. Confirm the coverage period, failure documentation required, return authorization process, and replacement or refund terms before purchasing.

4. Can replace IMMFP03B?

Do not assume that it can. The two variants have different memory capacities: has 2 MB SRAM and 512 KB NVRAM, while IMMFP03B has 8 MB SRAM and 2 MB NVRAM.

Check the application memory requirement and installed system configuration before approving a substitution.

5. What should engineers check before installing the replacement?

Record the existing processor’s hardware revision, firmware information, application configuration, redundancy arrangement, and connected I/O architecture. Back up the control application before removing the board.

For critical INFI 90 assets, keep 1 verified spare on site. That buffer stock is usually easier to justify than an extended process outage caused by a hard-to-source legacy processor.
