Introduction
The purpose of this document is to ensure that users who use a Vnet/IP control bus understand
the Vnet/IP system conguration, necessary precautions to set up the system, and the settings
required to create a control network system before they set up a Vnet/IP system.
Chapter 1 describes Vnet/IP. Chapters 2 and 3 provide the information required to congure a
Vnet/IP system. Ensure that you read Chapter 1 rst if you are not familiar with the background of
Vnet/IP.
Chapter 1 provides an overview of the Vnet/IP system conguration when it is used as a control
network, and the devices required for the system.
Chapter 2 describes the Vnet/IP network settings based on system conguration examples.
It provides examples of the basic system conguration, multiple domain conguration, and
connection with existing systems. These examples describe the required devices, settings, and
information when setting up the network. We recommend that you evaluate the general Vnet/IP
system conguration by following these examples. You must read Chapter 1 rst to understand
Chapter 2.
Chapter 3 describes the Vnet/IP network settings in a system conguration that does not use
information network but uses Vnet/IP to perform communication that is normally done on an
information network. It provides examples of the basic system conguration and multiple domain
conguration. These examples also describe the required devices, settings, and information
when setting up the network. To set up a system without using information network, you have to
fully understand the conditions described in Chapter 1.6 of this document, and then congure
and run the system appropriately. You must read Chapter 1 rst to understand Chapter 3.
Chapter 4 describes the layer 2 switches, layer 3 switches, cable for Vnet/IP, time
synchronization in the Vnet/IP system, and necessary precautions when installing network
devices. Time synchronization is important for the electronic records; electronic signatures (21
CFR Part 11) compliant system of Food and Drug Administration (FDA) or for the Sequence of
Event (SOE) system.
This document addresses the Vnet/IP network conguration as a control network. When Vnet/
IP is connected to an external network, it is necessary to take security issues into consideration.
Therefore, this document does not provide complete information on the required network
conguration or settings. When connecting to an external network, contact the network
administrator to determine the appropriate network conguration.
With the release of CENTUM VP R5.01 and ProSafe-RS R3.01, the guidelines are changed so
that Vnet/IP is used as a network for control communications, and other communications are
performed on an information network other than Vnet/IP. This document is customized to address
this change. Refer to “TI 30A10A10-01 Vnet/IP Network Construction Guide (Legacy Edition)” for
the legacy guide.
