Functions

DeviceNet Scanner: Acts as a scanner to manage communication with up to 63 DeviceNet devices, collecting and sending data to the ControlLogix controller.

Data Exchange: Supports polled, cyclic, and change-of-state I/O messaging for real-time control, as well as explicit messaging for configuration and diagnostics.

I/O Control: Manages digital, analog, and specialty DeviceNet devices (e.g., sensors, actuators, drives) without requiring additional message instructions.

Diagnostics: Provides status LEDs and diagnostic data for monitoring network health, device status, and fault detection.

Multi-Device Integration: Connects ControlLogix systems to DeviceNet devices like motor starters, drives, or sensors, enabling seamless integration.

Removal/Insertion Under Power (RIUP): Supports installation/removal with chassis power on, provided safety precautions are followed to avoid electrical arcing in non-hazardous areas.

Legacy and Modern Bridging: Interfaces modern ControlLogix systems with DeviceNet devices, supporting hybrid or legacy system integration.

Application Scenarios

Manufacturing Automation: Connects ControlLogix controllers to DeviceNet devices like sensors, actuators, or drives in automotive or electronics assembly lines for real-time control.

Process Control: Used in industries like food and beverage, chemical, or water treatment to manage distributed I/O devices over DeviceNet.

Material Handling: Supports conveyor systems, automated guided vehicles (AGVs), or packaging equipment by enabling communication with DeviceNet-enabled motor starters or sensors.

Legacy System Upgrades: Bridges modern ControlLogix systems with existing DeviceNet networks, facilitating phased upgrades without replacing infrastructure.

Motion Control: Integrates with DeviceNet-compatible drives (e.g., PowerFlex) for coordinated motion in robotics or CNC applications.

General Automation: Suitable for applications needing reliable, low-cost communication with DeviceNet devices in standard industrial environments (0°C to +60°C).
