Yokogawa VF702

The Yokogawa VF702 is a Control Bus Interface Card designed to connect a computer (PCI Express host) to Yokogawa's proprietary V-net control bus. It enables the host to function as a node within the V-net network, and is commonly used in Yokogawa's CENTUM series distributed control systems (DCS), including CENTUM VP and CENTUM CS 3000 architectures . The card provides dual-channel redundancy with two independent BNC ports (BUS 1 and BUS 2), and is backward compatible with the older VF701 card, allowing mixed operation on the same V-net segment.
