Product Performance

Dual Ethernet ports support network ring topology construction for communication redundancy. Port data transmission rate auto-adapts to 10/100 Mbps, with throughput up to 200Mbps in full-duplex mode and data transmission delay ≤1ms, meeting real-time control requirements. The multi-protocol compatible design can simultaneously access PROFINET remote I/O, Modbus TCP intelligent instruments and Ethernet/IP devices, enabling seamless cross-brand system integration.

Built-in web server supports direct browser access to the configuration interface, allowing real-time viewing of port status, communication statistics and error logs. SNMP protocol supports access to industrial network management systems, realizing unified monitoring of IT and OT networks. The diagnostic system can real-time monitor port faults, protocol anomalies and bus communication interruptions, with fault information uploaded to the controller within 100ms and diagnostic coverage ≥99%.

Supports NTP time synchronization, with deviation from network clock ≤50ms, ensuring time consistency of cross-device event records. Industrial-grade hardware design can withstand low-temperature startup at -25°C and high-temperature operation at 70°C, with Mean Time Between Failures (MTBF) ≥500,000 hours, adapting to 24/7 continuous production scenarios.
