Product Overview

The ABB INNIS01 serves as a high-performance Network Interface Slave (NIS) Module for the ABB INFI 90 OPEN distributed control system (DCS) platform. This communication card establishes the primary network bridge between independent Process Control Units (PCU) and the high-speed Infinet plant loop.

The module offloads low-level network protocol tasks from the main controller, freeing up process hardware to execute critical control logic without communication lag. By managing deterministic data exchange across the plant network, this module maintains tight synchronicity and prevents data collisions across large-scale industrial architectures.

We supply this product exclusively as 100% brand new, original, and factory-sealed to ensure your plant network operates with zero downtime and full manufacturer compliance.

Engineering Advantages

• High-Speed Deterministic Networking: The onboard processing architecture supports selectable data rates up to 10 Mbaud. This high throughput ensures instantaneous delivery of critical alarm states and process variables across the global network loop.
• Massive Scalability Configuration: The communication engine handles up to 250 nodes per local loop and scales up to 62500 total nodes in a global system architecture. This capacity allows plants to expand infrastructure indefinitely without replacing the core network interface.
• Onboard Traffic Buffering: The card allocates 208 kB of dedicated RAM exclusively for local message buffering and data routing tables. This prevents data packet loss and maintains absolute system stability during high-volume plant network traffic bursts.
• Simplified Hardware Installation: The module fits directly into one standard slot of an INFI 90 OPEN Module Mounting Unit (MMU). The plug-and-play backplane connection eliminates individual wiring sequences, protecting the card from manual termination faults during hot-swaps or system upgrades.

FAQs

• Does this ABB INNIS01 module arrive in brand new condition?
• Yes. We only provide this module as 100% brand new, original equipment. It ships in its original factory-sealed packaging with intact factory seals to ensure it meets your plant's quality control standards.
• Can the INNIS01 handle variable network speeds on older systems?
• Yes. The module provides selectable communication rates of either 2 Mbaud or 10 Mbaud. This feature allows the board to sync seamlessly with older legacy plant loops or upgrade instantly to modern high-speed INFI 90 OPEN systems.
• What specific host interfaces work with this module?
• The INNIS01 integrates directly with major INFI 90 sub-systems. It links Process Control Units (PCU), Management Command Systems (MCS), Operator Interface Stations (OIS), and Infi-Net Computer Interfaces (ICI).
• How does the onboard memory protect against network congestion?
• The 208 kB RAM buffer isolates local process logic from global network surges. If the plant loop experiences a traffic spike, the INNIS01 buffers incoming and outgoing messages locally, keeping the process controller focused entirely on plant safety loops.
