6. Control Bus Interface Card
In a ProSafe-RS system, a safety engineering PC (SENG) is connected to safety control sta-
tions (SCSs) via the control bus interface card installed in the SENG. A control bus interface
card is a communication card that is installed in PC/A
T-compatible PCs.
• For V net, use a control bus interface card (Model: VF702/VF701) that supports connec-
tions to V net. The VF701 is supported in a PCI bus and the VF702 is supported in a PCI
Express. The VF701 and the VF702 have the same functions so the following explanation
is based on the VF702. The VF702 has two ports to support V net dual-redundancy. To
perform engineering and maintenance tasks for SCSs from a SENG via V net, install a
VF702 in the slot of a PC installed with SENG software, and connect V net cables (Mod-
el: YCB141) to the VF702.
• For Vnet/IP, use a Vnet/IP interface card (Model: VI702/VI701) that supports connections
to Vnet/IP. The VI701 is supported in a PCI bus and the VI702 is supported in a PCI Ex-
press. The VI701 and the VI702 have the same functions so the following explanation is
based on the VI702. The VI702 has two ports to support Vnet/IP dual-redundancy. To per-
form engineering and maintenance tasks for SCSs from a SENG via Vnet/IP, install a
VI702 in the slot of a PC installed with SENG software, and connect cables to the VI702.
