Product Overview

The ABB INNIS11 serves as the high-capacity communication backbone for the INFI 90® and Symphony Harmony distributed control systems (DCS). As a Network Interface Slave Module, it manages complex data traffic between Harmony Control Units (HCU), operator stations, and external supervisory networks. The INNIS11 excels in large-scale deployments, processing up to 1,500 points from Sequence of Events (SOE) I/O modules across a network of up to 1,000 HCUs. Its advanced logic engine handles massive trigger arrays, ensuring that critical alarms and process transitions transmit instantly across the Infi-Net fabric without data collisions.

Engineering Advantages

Massive Event Handling: The INNIS11 manages 1,500 SOE points simultaneously. This ensures that even during a total plant trip, the module timestamps and transmits every digital state change with millisecond precision for accurate root-cause analysis.
Complex Trigger Logic: With support for 256 complex triggers (each featuring 16 operands) and 3,000 simple triggers, this module offloads intensive communication logic from the primary controller. It allows for sophisticated "event-driven" reporting, reducing unnecessary network traffic while prioritizing critical data.
Large-Scale Network Integration: A single INNIS11 facilitates communication across up to 1,000 Harmony Control Units. This scalability makes it the ideal choice for geographically dispersed facilities, such as large-scale petrochemical complexes and multi-unit power generation plants.
Advanced EMI Shielding: Designed for the electrically noisy environments of turbine halls, the module incorporates multi-layer EMI shielding. This prevents signal corruption from high-voltage switchgear, maintaining stable communication during peak electromagnetic interference events.
Hot-Swappable Reliability: The module supports live-insertion into the Harmony rack. Technicians replace units without powering down the cabinet, ensuring that adjacent modules and critical control loops continue to function during network hardware maintenance.
100% Brand New Assurance: We deliver only original, factory-sealed ABB INNIS11 modules. This guarantees that the internal processing chips and 5 VDC power regulators meet original factory MTBF (Mean Time Between Failures) ratings, securing the long-term uptime of your DCS backbone.

FAQs

Q: What is the primary difference between the INNIS11 and standard network modules?

A: The INNIS11 is specifically optimized for high-density SOE (Sequence of Events) point management and large-scale HCU networking. It offers significantly higher trigger capacity (3,000 simple triggers) than entry-level interface modules.

Q: Does the INNIS11 require a companion module to function?

A: Typically, the INNIS11 works in conjunction with a Network Interface Master or a Transfer Module (such as the INICT series) to complete the bridge between the Infi-Net control bus and the supervisory computer network.

Q: Can the INNIS11 be used in older Bailey INFI 90 racks?

A: Yes. The INNIS11 maintains full backward compatibility with legacy INFI 90 rack architectures while providing the enhanced processing power required for Symphony Harmony and Symphony Plus modernizations.

Q: How do the complex triggers benefit system performance?

A: Complex triggers allow the module to "decide" when to send data based on multiple conditions (operands). This prevents the network from being flooded with redundant data, ensuring that only significant process changes consume bandwidth.
