Yokogawa VI702 S1 Vnet/IP Interface Card

The Yokogawa VI702 S1 serves as the primary VI702 Vnet/IP Interface Card utilized to execute real-time control bus communication across CENTUM VP and ProSafe-RS platforms. Mounted directly into host Human Interface Stations (HIS) or Engineering Stations (ENG) via a PCI Express slot, the card establishes a 1 Gbps full-duplex deterministic network link to transport control data between field control stations and central operating interfaces.

Channel-to-Bus Galvanic Isolation & Network Determinism

The VI702 S1 hardware architecture incorporates channel-to-channel and channel-to-bus galvanic isolation barriers. These physical electrical barriers isolate internal host PCI Express system logic from external field Ethernet cabling. By severing ground loops and suppressing common-mode electrical transients present on network lines, the card maintains transmission signal integrity under industrial electrical noise conditions. Operating over the deterministic Vnet/IP protocol layer, the card delivers low-latency packet processing with response latencies under 1 ms, preventing frame drops during high-volume data exchanges between distributed controllers and operator stations.

Frequently Asked Questions

Q: Can the VI702 S1 interface card operate alongside existing VI701 cards in the same host PCI Express bus?

A: Yes, the VI702 S1 maintains full backward compatibility and coexists with VI701 interface cards on the same bus to support dual-redundant Vnet/IP network configurations.

Q: What PCI Express mechanical slots support the physical installation of the VI702 S1?

A: The module uses a standard x1 PCI Express connector and installs into full-height PCIe slots ranging from x1 up to x16 lane widths compliant with CEM 1.0a specifications.

Q: What diagnostic states do the onboard LED indicators display during operation?

A: The RDY LED illuminates green when internal power and self-diagnostics pass, while RCV and SND LEDs flash green to indicate active network frame reception and transmission.

Field Installation Guidelines

Prior to inserting the VI702 S1 card into a host workstation chassis, turn off host system power and disconnect the main supply cable. Personnel must wear a grounded wrist strap to prevent electrostatic discharge (ESD) damage to PCI Express bus components. Align the card card-edge connector with an empty PCIe slot (x1 to x16 slot size) and press firmly until fully seated in the expansion socket. Secure the full-height mounting bracket with the retention screw to ensure continuous chassis earth continuity. Connect CAT5e UTP or higher rated shielded Ethernet cabling with standard RJ45 connectors, ensuring the cable strain-relief boot is engaged and bend radius limits (minimum 40 mm) are maintained within the cable ducting.
