Main Functions

1. High-Density Network Port Expansion

    

   Adds 14 gigabit copper ports to Stratix 5800 switch chassis, connecting large numbers of PLCs, HMIs, servo drives, remote I/O blocks, sensors and industrial cameras without deploying extra standalone switches, saving cabinet space and wiring cost.
2. Fiber Backbone Redundant Uplink

    

   Two SFP slots support fiber transceivers to create long-distance, noise-immune plant backbone connections. Fiber links eliminate electromagnetic interference from high-power inverters and servo motors, and enable redundant ring/star network topologies for system fault tolerance.
3. Real-Time Motion & Time Synchronization

    

   CIP Sync and IEEE 1588 PTP deliver microsecond-level time alignment across all network nodes, critical for multi-axis coordinated motion (electronic cam, flying shear, gantry synchronization) on packaging, automotive and CNC machinery.
4. Hot-Swap Maintenance Without Line Shutdown

    

   Modular plug-in design allows replacement of faulty expansion modules while the main switch chassis and production network remain online, drastically cutting unplanned equipment downtime during troubleshooting and upgrades.
5. Industrial Network Fault Diagnostics & Alarm Output

    

   Built-in alarm relay triggers external light/horn alarms for port failure, link loss or module hardware faults. All port, traffic and error logs are stored for remote troubleshooting via Studio 5000 or network management software.
6. IT/OT Network Segmentation & Traffic QoS

    

   Configurable VLANs separate production control (OT) traffic from office IT networks; QoS prioritization ensures EtherNet/IP motion and safety data transmit first, avoiding communication lag or machine safety trips caused by background data congestion.

Key Advantages

• Gigabit full-speed ports eliminate bandwidth bottlenecks for high-speed multi-servo motion control systems
• Wide -25°C cold-start rating fits cold storage, outdoor cabinet and northern workshop environments
• DLR ring redundancy ensures <3ms network recovery after single cable break, preventing full production halt
• Unified Rockwell automation ecosystem, fully compatible with all Logix controllers and Kinetix motion drives
• Hot-swap capability removes the need for full network power-off during module replacement
• Dual SFP fiber slots provide flexible long-distance plant backbone layout and redundant uplink paths
• Hazardous location certification for chemical, oil & gas, water treatment and mining process facilities
• Centralized switch configuration backup via SD card for fast system restoration after hardware replacement
