ABB IMMFP03 is a distinct INFI 90 / Symphony Harmony multifunction processor used as a controller-class processing module. ABB identifies it separately from IMMFP02, IMMFP03B and IMMFP12, so the existing page must be corrected without collapsing revisions.
- Product type: Multi-Function Processor
- Verified system family: Symphony Harmony / INFI 90 installed base
- GPI compatibility: MFP03 firmware revision G8 for ABB GPI 4.0
- GPI data-point capacity: Up to 4,000 for that application
Its verified role is to host control and interface applications in the installed Harmony architecture. For ABB's General Purpose Interface 4.0 application, an MFP03 at firmware revision G8 transfers configured analog and digital data between supported foreign devices and the Symphony operator or information-system environment. ABB documents up to 4,000 GPI data points, a foreign-device network of up to 50 PLCs, and function-code, UDF and Batch coexistence for the GPI application. These are software-application limits, not proof of the existing ApterPower page's memory, port, power, performance, origin or weight values. IMMFP03 is used in legacy process-control units in power, pulp and paper, water, chemical and heavy-industry installations. Exact CPU, memory, communication ports, I/O buses, dimensions, environment and redundancy must come from the matching ABB revision manual or physical nameplate.
Important Notice: Update existing ApterPower ID 774924 and preserve /Infi-90/immfp03; do not create a duplicate.

Confirm the physical nameplate, current ABB documents, and host-system requirements before installation or replacement.
Legacy controller executionHosts the installed process-control strategy in a verified INFI 90/Harmony rack.
Foreign-device data integrationRuns ABB GPI to exchange configured analog and digital data with supported PLCs.
Operator-system integrationExposes verified GPI data through the Symphony operator or information interface.
Migration baselinePreserves the exact legacy database, firmware and revision evidence for controller evolution.
Read and follow the exact ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1Update ApterPower ID 774924 in place and preserve its public canonical.
2Remove or HOLD unsourced existing origin, HS, weight, memory and performance claims.
3Verify exact IMMFP03 rather than IMMFP03B, IMMFP02 or IMMFP12.
4Treat GPI point and PLC limits as application-specific, not universal hardware ratings.
5Back up controller logic, UDF/Batch code, GPI configuration, firmware and licenses.
6Confirm rack, I/O, communication, termination, addressing and redundancy from approved drawings.
7Follow ABB/site ESD, isolation, outage, rollback and commissioning procedures.
8Test control outputs, peer data, GPI data, alarms and redundancy before release.
