n Virtual IP address for control network TCP/IP communications
The control network TCP/IP protocol is used for communications such as downloading recipes
in CENTUM from HIS to FCS. It is also used for communications between SENG SCS Manager
and SCS in ProSafe-RS. Vnet/IP protocols support encapsulated control network TCP/IP
protocols or TCP/IP over V net to remain compatible with the existing V net system. For this
purpose, you have to set a virtual IP address. In normal conditions, use the following default IP
address that is automatically determined by the domain number and station number:
• IP address: 172.16.<domain number>.<station number>
• Subnet mask: 255.255.0.0

n Vnet/IP station IP address
The following table provides the Vnet/IP station IP addresses corresponding to the Vnet/
IP station types. The IP addresses for control network TCP/IP protocol communications are
recommended for CENTUM and ProSafe-RS. This table also provides the recommended IP
addresses for network interface cards that are used for information networks.
