Product Overview

The ABB INNIS21 serves as the essential high-speed front end for every Cnet communication interface within the Symphony Plus and INFI 90® distributed control systems (DCS). This intelligent Network Interface Module acts as the primary link between a specific node and the broader Cnet (Infi-Net) fabric. Working in tandem with the INNPM22 processor module, the INNIS21 enables any node to communicate with any other node across the entire system. It handles the low-level communication protocols required for massive-scale industrial networking, supporting infrastructures with over 62,000 nodes.

Engineering Advantages

Unrivaled Scalability: The INNIS21 supports over 62,000 nodes globally and 250 nodes on a single network segment. This enables massive-scale industrial integration for large power grids, multi-unit generation plants, and complex petrochemical refineries.
Selectable High-Speed Throughput: The module offers three communication rates: 10 Mbaud, 2 Mbaud, and 0.5 Mbaud. This flexibility allows engineers to optimize network performance based on cable length and existing infrastructure requirements while ensuring 10Mbaud speeds for modern high-bandwidth demands.
Microprocessor-Based Intelligence: The onboard microprocessor handles complex communication tasks independently. This offloads the processing burden from the main controller, ensuring that process control strategies remain fast and deterministic even during periods of heavy network traffic.
Dedicated Expander Bus Segment: The INNIS21 communicates with the INNPM22 module via a dedicated I/O expander bus. This private data lane prevents bottlenecks and ensures high-integrity synchronization between the network interface and the command processor.
Robust EMI Shielding: Designed for the harsh electromagnetic environments found in turbine halls and motor control centers (MCC), the INNIS21 features advanced EMI shielding and surge protection. This prevents data corruption from high-frequency interference.
100% Brand New Condition: We supply only original, factory-sealed ABB units. This ensures the integrity of the 5.5W power circuitry and communication logic, avoiding the reliability risks and timing jitter often found in refurbished or "rebuilt" hardware.

FAQs

Q: Does the INNIS21 require a specific processor module to function?

A: Yes. The INNIS21 is designed to work in conjunction with the INNPM22 Network Processor Module. Together, they form the complete communication interface for a Symphony Plus or Harmony node.

Q: Can I use the INNIS21 to replace older INNIS models?

A: Absolutely. The INNIS21 offers improved communication speeds and enhanced protocol support compared to earlier versions. It maintains backward compatibility with the INFI 90® architecture while providing a path to Symphony Plus modernization.

Q: How does the module handle network redundancy?

A: The INNIS21 supports redundant Cnet configurations. In typical mission-critical applications, two modules work in parallel to ensure that a single cable or module failure does not interrupt communication between the controllers and the operator stations.

Q: What is the significance of the 10 Mbaud communication rate?

A: The 10 Mbaud rate significantly reduces the latency of process data and alarm transmission. This allows the Symphony system to handle larger volumes of SOE (Sequence of Events) data without network saturation during a major plant trip or upset.
