This interface card provides dedicated Vnet/IP network connectivity for Yokogawa CENTUM control systems. It enables high-speed data exchange between field control units and operator stations. We designed the Yokogawa VI702 S1 specifically for the CENTUM VP and CENTUM CS platforms. This card handles all network communication tasks with minimal CPU intervention. It ensures reliable, real-time data transmission across your distributed control infrastructure. Therefore, your operations gain seamless visibility into plant-wide process conditions.
Physical Configuration and Hardware Layout
The Yokogawa VI702 S1 features a compact PCI-based form factor for system integration. Its dimensions measure 160.0 mm in length and 100.0 mm in height. The card weighs approximately 0.35 kilograms for straightforward handling procedures. This unit installs directly into the dedicated network slot of the CENTUM station. It connects to the Vnet/IP network via dual copper Ethernet ports. The card incorporates an onboard processor for protocol management tasks.
Network Capabilities and Transmission Performance
This interface card delivers Vnet/IP communication at 1 Gbps bandwidth. It supports both dual-redundant and single network configurations for application flexibility. The Yokogawa VI702 S1 handles data packets with exceptionally low latency. It maintains synchronization with system clocks for time-stamped event data. The card supports up to 64 connections simultaneously for comprehensive network coverage. It includes diagnostic LEDs for link status and data activity monitoring. Consequently, this allows quick identification of network connectivity issues.
