3. Key Features
3.1 Redundant & Reliable Communication
Equipped with dual redundant Gigabit Ethernet ports and backup RS-485 interface, the module eliminates single points of failure in communication links. Automatic failover (≤100 ms) ensures uninterrupted data transmission, critical for safety-related applications like emergency shutdown systems in petrochemical plants.
3.2 Multi-Protocol Compatibility
Support for EtherNet/IP, Modbus TCP/IP, and Yokogawa’s proprietary Vnet/IP enables seamless integration with Yokogawa DCS and third-party automation devices (e.g., Rockwell PLCs, Emerson transmitters). This multi-protocol capability simplifies system expansion and retrofitting in mixed-brand industrial environments.
3.3 Deterministic & Low-Latency Transmission
With a data transfer rate of 1 Gbps and latency ≤2 ms, the module ensures real-time transmission of process control signals. The deterministic communication mechanism guarantees consistent data delays, avoiding unpredictable responses in time-sensitive applications like batch processing in pharmaceutical facilities.
3.4 Robust Environmental Adaptability
The module operates reliably over a wide temperature range (-10°C–60°C) and features IP40-rated housing, making it suitable for both control room and field-mounted applications. Enhanced EMC performance (compliant with IEC 61000-4) resists interference from industrial electrical noise, ensuring stable operation in refineries and power plants.
