INNIS21 ABB Infi-Net to Node Comm Interface

INNIS21 ABB Infi-Net to Node Comm Interface

INNIS21  Quick Details:

• Model:  INNIS21R
• Brand: ABB
• Product role: Network interface module in ABB Symphony system
• Main function: As a communication bridge, establish connections and data transmission channels between Cnet (factory network) and controllers
• Core technology: Supports 10 Mbps data transmission rate, usually paired with INNPM22 module to complete complete complete communication
• Key feature: Supports redundant configuration and enables uninterrupted system switching
• Physical specifications: In the form of a board, it needs to be installed in the slot of the module installation unit

Core functions and working principles:

• The core function of the INNIS21 module is to process different types of network information, ensuring reliable exchange of factory production data and control instructions. The basic working principle is:
• Network side connection: The module side is connected to the factory level high-speed Cnet network, allowing the controller unit to participate in data exchange throughout the factory.
• Controller side connection: The other side is connected to the control channel through its pairing module (such as INNPM22), making the controller an independent network node.

Important application features:

• Redundant configuration: In order to meet the extremely high reliability requirements of industrial sites, INNIS21 can be used in pairs to form primary and backup redundancy. When a module in operation fails, the backup module can take over the work in a very short time, ensuring the continuous operation of the system.
• Error handling mechanism: The module has built-in retransmission logic, which will perform multiple retries when data transmission fails, while continuously
• monitoring and updating the status of each node in the network.

Application field:

• This module is designed specifically for critical industrial processes that require high reliability. The main application areas mentioned in the search results include:
• Energy industry: Distributed Control Systems (DCS) for chemical, petroleum, natural gas, power, and water treatment plants
  Large scale infrastructure, such as monitoring systems for rail transit.
