Product Performance
Communication compatibility is strong: It covers mainstream industrial Ethernet and serial protocols, and can directly connect to PLCs, DCS and terminal devices from different manufacturers. No additional protocol conversion modules are required, enabling seamless interconnection between VME systems and industrial networks.
Redundancy reliability is outstanding: Ethernet link aggregation and hot-standby redundancy design ensure uninterrupted communication; switching time ＜10ms meets the real-time requirements of industrial control, avoiding system shutdown caused by single-point faults.
Data transmission is efficient: Gigabit Ethernet ports combined with 8MB buffer allow a single module to carry over 1000 concurrent connections; data transmission delay ≤1ms (in local area network), meeting the needs of large-scale I/O data acquisition and control command issuance.
System integration is convenient: The standard VMEbus interface can be directly embedded into GE Fanuc VME series industrial computers, supporting real-time operating systems such as VxWorks and Linux. Protocol parameters and communication logic can be quickly configured through the configuration tools provided by the manufacturer.
Environmental adaptability is excellent: The wide temperature range of -40℃ to +85℃ covers extreme industrial scenarios; anti-vibration and anti-electromagnetic interference design ensures stable operation in high-interference environments such as power and metallurgy industries, without communication packet loss or protocol anomalies.
