ABB IMMPI01 is a Harmony Rack Multifunction Processor Interface Module that handles the I/O interface between a host computer and an INICT03A Computer Transfer Module. Despite its name, it is a communication interface, not the IMMFP process controller.
- Function: Host-computer I/O interface for INICT03A
- Ports: Two RS-232-C; one SCSI
- RS-232-C mode: DCE or DTE, determined by exact configuration
- Power: +5 VDC at 415 mA; approximately 2.1 W
The module passes host-computer data to and from INICT03A so the computer-transfer interface can exchange system information with the installed Harmony/Cnet architecture. For RS-232-C operation it can be configured as DCE or DTE. ABB documents two RS-232-C ports and one SCSI port, +5 VDC at 415 mA (about 2.1 W), and a ribbon-cable connection to INICT03A. RS-232-C field connection uses NTMP01, while the SCSI connector is on the module faceplate and does not use a termination unit. IMMPI01 is used in Cnet-to-computer interfaces, operator/information-system connections, maintenance workstations, and legacy INFI 90/Harmony computer-transfer installations. Exact host software, cable, handshake jumpers, DCE/DTE mode, firmware and cybersecurity controls must be verified.
Important Notice: Do not describe IMMPI01 as an IMMFP controller; it is a communications interface used with INICT03A.

Confirm the physical nameplate, current ABB documents, and host-system requirements before installation or replacement.
Cnet-to-computer interfaceProvides the host-side I/O path for an INICT03A computer-transfer interface.
Operator/information-system connectionMoves system data to supported host applications through RS-232-C or SCSI.
Legacy host modernizationPreserves exact cable and port mapping during workstation replacement.
Communication diagnosticsSupports verified testing of host, INICT03A and system data paths.
Read and follow the exact ABB documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1Update product ID 774765 in place and preserve the current public canonical.
2Verify IMMPI01 rather than an IMMFP controller or INICT transfer module.
3Back up host configuration, point mapping, drivers and interface settings.
4Confirm INICT03A revision, ribbon cable, NTMP01, DCE/DTE mode and handshake jumpers.
5Power down and follow ABB/site ESD and module insertion/removal procedures.
6Do not hot-connect legacy SCSI or RS-232-C interfaces unless the exact ABB procedure permits it.
7Test host communication, data direction, point mapping, alarms and system diagnostics before release.
8Do not publish origin, HS code, dimensions, weight or present lifecycle without exact ABB evidence.
