Function

Redundant communication: Supports ControlNet redundant network configuration to ensure communication reliability. Interlocking between controllers and I/O updates take precedence over message passing or program upload/download.

High-performance data exchange: Achieves high-speed and synchronous data transmission through dual channels (2 BNC ports), suitable for real-time control.

Harsh environmental adaptability: The Logix-XT design can withstand extreme temperatures (-25°C to +70°C), making it suitable for harsh industrial environments.

Flexible installation: It can be installed in any slot of the ControlLogix rack and supports seamless integration with the ControlLogix 5570/5580 controller.

Status monitoring: Provide operational status and diagnostic information through the digital display screen on the module.

USB interface: It provides a USB port for easy configuration and debugging.

Safety support: Supports sports safety functions (such as Safe Torque Off) and complies with TUV EC certification.

Application scenarios

Process control: such as in the petrochemical, oil and gas or water treatment industries, it is used in distributed control systems (DCS) to ensure redundant communication and high availability.

Manufacturing automation: In automotive manufacturing or electronic assembly lines, PLC, I/O modules and HMI are connected to achieve high-speed data exchange and synchronous control.

Motion control: Supports robots or CNC equipment, and achieves precise servo driver communication through the ControlNet network.

Heavy industry: such as the steel, mining or energy industries, providing reliable network connections in high temperature, low temperature or corrosive environments.

Redundant system: It is used in scenarios where controller redundancy is required (such as critical mission control) to ensure that the system can still operate normally in the event of a network failure.
