3.8 Connecting Bus Cable
There are three types of control network bus named as Vnet/IP, and Vnet/IP-Upstream for
the ProSafe-RS system.
Vnet/IP or Vnet/IP-Upstream is used for SSC60S/SSC60D, SSC50S/SSC50D and SSC57S/
SSC57D. Vnet/IP-Upstream is the same connection as Vnet/IP.
This section describes each control network bus cabling and ESB bus cabling related to
the control network bus.
3.8.1 Vnet/IP network
Information on Vnet/IP interface connection and an example of SENG and SCS connection are
shown below:
 Vnet/IP Interface
