Product Overview

The ABB Bailey IMMPC01 is an INFI 90 Multiprocessing Module used within Bailey distributed control system architectures where multiple processing functions need to operate as part of the same control-system environment. It supports multiprocessing tasks within the INFI 90 architecture and works alongside other controller, communication, and I/O modules.

In a typical INFI 90 installation, different processing functions may need to exchange data while maintaining coordinated operation across the control network. The IMMPC01 provides additional processing capability within this architecture, making it suitable for control systems with distributed processing requirements and established Bailey system hardware.

The module is intended to operate as part of the INFI 90 system rather than as a standalone PLC. Its application depends on the surrounding controller configuration, system communication structure, and the processing functions assigned to the module.

Technical Specifications

Product Features

• Provides multiprocessing capability within the ABB Bailey INFI 90 architecture.
• Supports distributed processing functions in an established control-system environment.
• Works with compatible INFI 90 controller, communication, and I/O infrastructure.
• Suitable for systems requiring additional or distributed processing resources.
• Intended for integration into existing Bailey control-system architectures.
• Can be used for maintenance or replacement of compatible INFI 90 multiprocessing hardware.

Working Principle

The IMMPC01 operates as a processing resource within the INFI 90 control architecture. Instead of handling field signals directly, it works with system-level processing tasks assigned through the surrounding Bailey control-system configuration.

Data generated by connected I/O and controller components can be exchanged through the INFI 90 communication architecture. The IMMPC01 processes the information associated with its assigned functions and exchanges the resulting data with other system components. This distributed approach allows processing tasks to be shared across the control-system architecture rather than concentrated in a single processing location.

During maintenance or replacement, the module must be matched with the appropriate INFI 90 system configuration. Hardware compatibility, module addressing, communication paths, and application configuration should be verified before returning the module to service.

Industrial Applications

Installation and Maintenance

1. System Compatibility — Confirm that the IMMPC01 matches the existing INFI 90 system architecture and assigned processing function.
2. Module Identification — Verify the module designation before removing an existing unit or installing a replacement.
3. Power Isolation — Follow the plant’s approved shutdown and electrical isolation procedure before accessing the control-system hardware.
4. Backplane Connection — Inspect the module position and backplane interface for contamination, damage, or poor contact.
5. Configuration Backup — Preserve relevant system configuration information before replacing the multiprocessing module.
6. Module Addressing — Verify the required module or node addressing against the existing INFI 90 system configuration.
7. Communication Checks — Inspect the associated communication paths and connectors for secure connections and physical damage.
8. Module Seating — Install the IMMPC01 fully into its assigned position and ensure that the module is mechanically secured.
9. Status Monitoring — Check module status indications during startup and compare them with normal system conditions.
10. Diagnostic Review — Use available INFI 90 diagnostic information to identify configuration, communication, or processing faults.
11. Functional Testing — Verify data exchange and assigned processing functions after installation before returning the affected control loop to normal operation.
12. Maintenance Records — Record the replacement module model and relevant configuration information to support future troubleshooting.

Technical FAQs

What is the primary function of the ABB Bailey IMMPC01?

The IMMPC01 is an INFI 90 Multiprocessing Module used to provide processing resources for assigned functions within the Bailey distributed control architecture.

Does the IMMPC01 directly connect to field sensors and actuators?

The IMMPC01 is a multiprocessing module rather than a conventional field I/O module. Field signal acquisition and output functions are normally handled by the appropriate INFI 90 I/O hardware, while the IMMPC01 performs assigned processing functions within the system.

What should be checked when replacing an IMMPC01?

The replacement should be checked against the existing system configuration, module designation, addressing, communication arrangement, and application requirements. Preserving the original configuration before replacement is also important for restoring normal operation.

What can cause an IMMPC01 to fail to operate correctly after replacement?

Incorrect system configuration, addressing problems, poor backplane contact, communication issues, or incompatibility with the existing INFI 90 architecture can prevent normal operation. Module status indications and available system diagnostics should be checked during commissioning.
