Yokogawa VF702 Control Bus Interface Card for V net Communication and CENTUM Systems

Reliable control network communication is essential for maintaining stable data exchange between engineering stations, operator stations, and distributed control systems. The Yokogawa VF702 is a Control Bus Interface Card designed to connect a PC to the V net control network used in Yokogawa CENTUM systems. As the PCI Express version of Yokogawa's V net interface cards, VF702 provides a dedicated hardware connection between compatible PCs and the control bus, supporting reliable communication in engineering and supervisory applications. Its dedicated V net interface helps integrate PC-based stations into the existing control-system network without replacing the underlying control architecture.

The VF702 is commonly used in Yokogawa CENTUM engineering or supervisory PC stations where a computer needs to communicate with the existing V net control network. Its primary function is to provide the PC with a dedicated V net interface through a PCI Express slot, allowing control-system data to be exchanged with the connected CENTUM environment. When replacing a VF702, verify the PC slot type and existing V net cabling, as VF702 uses PCI Express and BNC/10BASE-2 communication rather than a standard Ethernet interface.
