      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • VI702 S1 links a compatible CENTUM workstation to a Vnet/IP control network through a PCI Express host interface.
      Network role: CENTUM Vnet/IP workstation interface
      Host connection: PCI Express x1
      Service focus: Preserve station and switch mapping
      The VI702 provides a workstation connection to the Yokogawa Vnet/IP control network. Its PCI Express x1 host interface exchanges data with the communication functions used by the installed control-system software.

      The documented physical network is 1000BASE-T at 1 Gbit/s full duplex through an RJ45 connection. Category 5e UTP cabling is specified for the card-to-L2-switch link, with a 100 m maximum in the referenced installation. Network design still depends on the approved Vnet/IP topology and switch configuration.

      The Style S1 card uses a 3.3 V PCIe supply with a maximum 2.5 A requirement. Installation must match the workstation slot, supported operating environment and required redundancy or network separation. Verify the complete VI702 S1 marking and record the original interface configuration before replacement.
      Controller platform reference: Yokogawa CENTUM FIO / Vnet/IP. Match the installed configuration and interfaces.
      Technical downloads for Yokogawa VI702 S1: a product technical reference and an installation verification guide.
      These Apter Power documents consolidate the verified product facts and practical checks for the complete offered marking. Confirm the installed system configuration before service.
      Application context: A compatible CENTUM workstation uses VI702 S1 to join the engineered Vnet/IP control network for operator and engineering station communication.

      Compatibility scope: Confirm the approved workstation, PCIe host interface, Vnet/IP topology and switch-port assignment before installing the Style S1 card.
      Installation and commissioning checks for Yokogawa VI702 S1.
      Confirm workstation support

      Check the approved host model, PCIe slot and installed CENTUM release.

      Preserve network mapping

      Record Vnet/IP port assignment, switch connection and station settings.

      Check cable path

      Use the specified Cat 5e link and stay within the documented 100 m card-to-switch length.

      Protect the card

      Remove power and use ESD controls before handling the PCIe interface.

      Keep network separation

      Maintain the project network topology and any required redundant paths.

      Verify the station

      Check interface recognition, link state and communication after commissioning.

      Alternative Names

      VI702-S1, VI702 S1 Vnet/IP interface card, Yokogawa VI702 Style S1

      Technical notes

      Technical basis: Yokogawa GS 33J50C10-01EN, Vnet/IP Interface Card VI702, Style S1.

      Applicability: VI702 Style S1 information applies to the offered VI702 S1 marking.

      Integration focus: Workstation support, Vnet/IP path assignment and switch topology are installation-specific and should be matched to the existing control system.

      FAQ View All FAQ

      • What should be checked if a workstation does not recognize VI702 S1 after installation?
        Confirm the approved host platform, PCIe seating, installed control-system software and station diagnostics before replacing the interface card.
      • How should Vnet/IP path assignment be preserved when changing VI702 S1?
        Record the original port-to-switch mapping and host network settings; restore them under the system configuration procedure.
      • What does an absent link indication on VI702 S1 suggest?
        Check the RJ45 seating, cable, connected switch port, workstation recognition and network configuration before attributing the problem to the card.
      • Can VI702 S1 be inserted into a generic Ethernet network instead of Vnet/IP?
        The card is specified for Yokogawa Vnet/IP. A standard RJ45 connector alone does not establish support for an unrelated Ethernet application.
      • How should intermittent Vnet/IP traffic be diagnosed with VI702 S1?
        Compare the card and switch link indications, cable condition, port assignment and network diagnostics against the approved Vnet/IP topology.
      • Why can VI702 S1 lose communication while the workstation remains powered?
        Check card recognition, PCIe seating, the host slot supply, network cable and connected switch port to isolate the fault before attributing it to the card.
      • What should be checked after moving VI702 S1 to a replacement workstation?
        Verify card recognition, Vnet/IP link state, network mapping and communication with the configured control system.
      • Why must network topology be reviewed before fitting VI702 S1?
        The card participates in a defined control network; switch placement and any required redundancy belong to the approved system design.
