Product Features
ABB INNIS21 features a dedicated communication processor that supports three communication rates, 10Mbps, 2Mbps, and 0.5Mbps, enabling real-time processing of high-frequency data interactions in industrial environments. Through the Profit Loop algorithm, system stability is improved by 30% compared to traditional PID control, making it particularly suitable for scenarios with extremely high control precision requirements, such as chemical and power industries.
ABB INNIS21 supports hot-swappable modules, enabling maintenance without downtime, significantly reducing the risk of production interruptions. It also provides redundant communication interfaces to ensure uninterrupted data transmission even in the event of a single-link failure.
ABB INNIS21 is equipped with Ethernet, RS485, and Profibus DP interfaces, natively supporting mainstream protocols such as Modbus, Profibus, and DeviceNet, enabling seamless integration with third-party devices.
ABB INNIS21 supports various types of expansion modules, including
Digital I/O modules: High-density input/output nodes suitable for discrete device control.
Analog I/O modules: 12-bit resolution, supporting the acquisition of continuous variables such as temperature and pressure.
Special-function modules: Such as counters and pulse output modules, meeting motion control requirements.
Product Using Principle
ABB INNIS21 serves as the front-end interface for the Cnet network, connecting to the Cnet bus via a microprocessor communication circuit and collaborating with the IN NPM 22 module through a dedicated I/O expansion bus. Its core function is to convert field device protocols into a format recognizable by the Cnet network, enabling cross-device data interaction.
ABB INNIS21 receives sensor signals, performs analog-to-digital conversion, and parses protocols, achieves real-time mapping of Modbus/Profibus to Cnet protocols via its built-in processor, control commands are sent to actuators via expansion modules to form a closed-loop control system.
