More Information

Overview Manuals Applications Communication Programming Integration

Features:

  • Executes analog, sequential, batch and advanced control strategies in one rack processor.
  • Provides 512 kB RAM and 256 kB nonvolatile memory for the controller database.
  • Communicates with process I/O through the Expander Bus and peer controllers through Controlway.
The selected processor is the higher-memory member of the ABB multifunction-processor pair and occupies one standard INFI 90 OPEN rack slot. Its memory resources support larger control applications than the IMMFP11 variant.

The processor collects field information from connected rack I/O, executes the loaded control strategy and exchanges data with other Harmony controllers. Serial ports and the redundancy link extend its role to external devices and paired-controller arrangements.

A replacement must retain the validated configuration, node addressing and redundancy state of the installed controller. Confirm the rack power budget and each communication connection before downloading the application.

Availability is evaluated for the exact Harmony Rack processor and required system context.

  • Runs continuous analog control loops for process units using Harmony rack I/O.
  • Coordinates sequential and batch logic where local controller execution is required.
  • Supports advanced control and user functions in established INFI 90 OPEN installations.
  • The Expander Bus links the processor to local analog and digital I/O modules.
  • Controlway provides communication with other Harmony rack controllers and bridge controllers.
  • Two serial channels can be arranged as RS-232-C ports or as one RS-485 plus one RS-232-C port.
  • Control strategies may use function codes, C, Basic, Batch 90, Ladder and user-defined functions.
  • The controller database should be backed up and validated before a processor is exchanged.
  • Redundant pairs require synchronized application data and verified mate-link status before process control resumes.
  • The module occupies one slot in a standard INFI 90 OPEN mounting unit.
  • Rack power must supply +5 V DC at up to 2 A while dissipating as much as 10 W.
  • Serial termination and network node assignments must match the installed control-system design.
Description
ABB IMMFP12 is a Harmony Rack multifunction processor designed to execute multiple-loop analog, sequential, batch and advanced control strategies. Its processing architecture combines a 32-bit microprocessor with program, working and nonvolatile memory sized for demanding INFI 90 OPEN applications.

The controller exchanges process data with Harmony analog and digital I/O modules through the Expander Bus and communicates with peer rack controllers over Controlway. Serial interfaces support external devices, while the redundant communication link allows a paired processor arrangement where the system design requires it.

Engineering work should confirm the rack mounting unit, communication topology, loaded control database and termination devices before a module exchange. Because memory contents and application configuration are essential to operation, preserve the validated controller program and verify redundancy synchronization before returning the process to service.

Technical notes
ABB IMMFP12 replacement work must preserve the validated control database and nonvolatile-memory content before power removal. Confirm Expander Bus, Controlway and redundancy-link assignments so a replacement processor does not enter service with an incorrect node configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What distinguishes ABB IMMFP12 from IMMFP11 in the Harmony Rack family?
ABB documents that IMMFP12 provides twice the memory capacity of IMMFP11, with 512 kB RAM and 256 kB NVRAM for control applications.
How does ABB IMMFP12 reach process I/O in an INFI 90 OPEN rack?
It communicates with the rack analog and digital I/O modules through the Expander Bus, while Controlway carries peer-controller communication.
Which control workloads are appropriate for ABB IMMFP12?
It is designed for multiple-loop analog, sequential, batch and advanced control, including strategies implemented with function codes, C, Basic, Batch 90 or Ladder.
What data must be secured before exchanging ABB IMMFP12?
Back up the validated controller configuration and any required nonvolatile data, then document node, serial-port and redundancy assignments before removing power.
Which ABB document covers ABB IMMFP12 hardware limits?
The Manuals tab includes the official ControlIT Multifunction Processors data sheet WBPEEUD230002A1 with memory, power, communications and environmental data.
How can a buyer request a checked ABB IMMFP12 quotation?
Provide quantity, destination, rack/controller context, required condition and whether a redundant mate is installed so sourcing and compatibility checks can be included.
