ABB INNPM12 Network Processor Module

Description

ABB INNPM12 Network Processor Module

The ABB INNPM12 (Symphony Harmony Network Processing Module) is a high-performance network interface card for the ABB Symphony Enterprise Management and Control System (Symphony / Harmony / INFI 90) architecture.

Product Detailed Description

The INNPM12 serves as the primary communication gateway within the Symphony/Harmony rack system. It acts as the interface bridge connecting the local processing units (such as Harmony Area Controllers, BRC100/200/300 controllers, or HRU modules) to the Cnet (Control Network)—ABB’s redundant, high-speed, plant-wide communication backbone. It offloads network protocol processing from main control modules, ensuring high-speed data transfer across the entire DCS network without degrading loop control performance.

Technical Parameters

Product Advantages

• Offloaded Network Processing: Manages Cnet protocol communications independently, freeing up host controller processing cycles for critical control loops and logic execution.
• Seamless Redundancy Support: Configurable in dual-redundant pairs to ensure zero-loss transfer during module failure or cable damage on Cnet.
• High Reliability: Engineered for continuous 24/7 industrial service with onboard diagnostic LEDs for immediate status reporting and fault isolation.
• Backward Compatibility: Drops directly into existing INFI 90 and Symphony Harmony racks, simplifying migration and maintenance without necessitating complete system replacements.

Important Considerations & Precautions

• Electrostatic Discharge (ESD): The exposed PCB circuitry is highly ESD-sensitive. Wear a grounded wrist strap when removing or inserting the card into the MMU.
• Do Not Hot-Swap Without Verification: While Symphony Harmony supports online module servicing, ensure redundant network paths are established before removing an active INNPM12 to prevent communication dropouts on connected controllers.
• Firmware Revision Alignment: Always verify that the INNPM12 hardware and firmware revisions match the host controller (e.g., BRC100, BRC200, BRC300) and software requirements of your operational environment.
• Backplane Terminations: Ensure corresponding termination modules (such as NTMP01) and Cnet coaxial or fiber-optic cables are securely fastened and properly grounded.

Product Applications

• Power Generation: Used in thermal, nuclear, and combined-cycle plant distributed control systems (DCS) for linking turbine controls, boiler controls, and auxiliary systems.
• Oil, Gas & Petrochemical: Managing network communication across wide-area refinery control networks and offsite tank farms.
• Pulp & Paper Operations: Interfacing continuous process control units across large mill installations over redundant Cnet links.
• Water & Wastewater Treatment: Coordinating centralized supervisory control between distributed pumping stations and treatment facilities.
