VF702 Advantages
Yokogawa VF702 provides stable dual-redundant Vnet coaxial bus communication solutions for Yokogawa Centum VP human-machine stations. Stable operating performance. Dual independent BNC coaxial channels support seamless automatic redundant switching without HMI screen freezing, 10BASE-2 coaxial transmission reaches maximum 185m communication distance, low-latency dedicated communication chip ensures real-time synchronization of millisecond-level process data, built-in bus segment fault isolation function cuts off abnormal equipment to protect the whole Vnet network, fully meeting long-term uninterrupted large-scale plant centralized monitoring and operation demands. Strong environmental adaptability. Reinforced industrial PCB substrate and built-in multi-stage isolation circuits support 24-hour continuous operation under humid, dusty, high-temperature and strong electromagnetic interference central control room scenarios. Excellent anti-interference capability. Complete channel-to-channel galvanic isolation structure blocks power grid surge and cable crosstalk interference, coaxial transmission fundamentally avoids electromagnetic noise interference from frequency converters and large motors, effectively eliminates data jitter, screen stalling and intermittent network disconnection. Perfect system compatibility. Standard PCIe x1 host interface fully matches all mainstream Centum VP series supporting hardware including FCS CPU boards, AIP series optical transceivers, various I/O modules and Vnet bus couplers, realizing seamless bidirectional process data interaction between operator stations and all field control stations. Convenient maintenance design. Compact PCIe plug-in structure equipped with RDY running, RCV receiving and SND sending status indicator lights on the panel, supports dual redundant online replacement without workstation shutdown, simplifies on-site YCB146 coaxial cable wiring inspection, bus communication troubleshooting and rapid spare parts replacement. Industrial durable reliability. Manufactured strictly in accordance with Yokogawa industrial DCS communication card production standards, built-in full-time bus link self-diagnosis function, fully satisfying long-term stable Vnet control bus communication operation demands of field Centum VP control systems.
