Features:
- PCI Express interface for a PC/AT-compatible CENTUM system engineering station.
- Two coaxial V net ports maintain the control bus's redundant path arrangement.
- On-card switches assign the required domain and station identity.
VF702 S1 bridges the engineering computer and V net without merging the host-side PCI Express connection with the field-side coaxial network.
Both V net channels of VF702 S1 are presented as separate BNC connections, preserving the paired network topology used by the control bus.
Front-panel receive and send indicators make VF702 S1 traffic activity visible at the interface card, while the S1 style identifies the marine-standard configuration.
The YOKOGAWA VF702 S1 V net Control Bus Interface Card is available for purchase and support from Apter Power.

V net and host-side links
- Computer bus: The host connection uses a PCI Express slot in the system engineering station.
- Control network: Two independent interfaces attach the card to the redundant V net.
- Physical media: Each V net route uses coaxial cable and a BNC T connector.
- Bus continuation: The T connection accepts the preceding and following network segments or an end terminator.
Domain and station identity
- Domain setting: A dedicated switch bank selects the V net domain number.
- Station setting: A separate switch bank defines the system engineering station number.
- Pre-start setup: Address switches are set before the station enters normal network operation.
- Identity boundary: The configured domain and station pair distinguishes the host on V net.
Card and network placement
- Host format: The card fits a PC/AT-compatible SENG equipped with PCI Express.
- Network pairing: Both redundant V net cables are connected to their corresponding interfaces.
- Activity check: RCV and SND indicators provide a local view of receive and transmit traffic.
- Segment endpoint: A terminator is installed on the open side of the T connector when the card occupies a bus end.
S1 compliance distinction
- Style code: S1 identifies a defined hardware style within the VF702 card family.
- Marine conformity: The S1 configuration is the VF702 style specified to meet marine standards.
- Model control: The complete VF702 S1 designation is required when confirming this compliance variant.
- Interface basis: Compliance applies to the PCI Express V net interface configuration represented by the S1 code.
