Functions

Data Broadcasting: Facilitates high-speed data transfer (5 Mbps) between ControlLogix chassis via SynchLink fiber-optic cables, enabling coordinated drive and motion control.

Time Synchronization: Synchronizes system time across multiple ControlLogix chassis, ensuring precise coordination for distributed control systems.

Motion Axis Data Sharing: Allows motion axis data to be consumed by controllers in different chassis, supporting distributed motion applications.

High-Speed Communication: Provides synchronous communication with a 50 μs frame speed for real-time control.

Flexible Installation: Can be installed in any slot of a ControlLogix chassis, supporting both standard and redundant power supplies.

Diagnostics: Features status LEDs for monitoring module operation and communication status.

Robust Design: Operates reliably in clean, dry industrial environments, with fiber-optic communication reducing electromagnetic interference.

Application Scenarios

Motion Control Systems: Synchronizes multi-axis motion in robotics, CNC machines, or automated assembly lines for precise coordination.

Drive Control: Coordinates ControlLogix controllers with PowerFlex 700S drives in applications like packaging or material handling.

Distributed Control Systems: Enables time synchronization and data sharing across multiple chassis in industries such as automotive, aerospace, or semiconductor manufacturing.

Manufacturing Automation: Supports high-speed data exchange in production lines for real-time control of conveyors, pick-and-place systems, or palletizers.

Process Control: Used in industries like oil and gas or chemical processing to ensure synchronized operation of distributed equipment.
