Centum VP consists of four components which are operation and monitoring functions, engineering functions, control functions and a network communication system.
Human Interface Station (HIS)
Field Control Station (FCS)
Centum VP System (HIS, FCS and Vnet/IP Network)
Components of Centum VP
Human Interface Station (HIS)/Engineering Workstation (EWS)
This station is used mainly for operating and monitoring plant functions. With optional engineering software, system builder functions can be defined.
The FCS provides control of the plant functions through instruments in its database. Process information is placed on the Vnet for monitoring or control by an HIS.
A process automation control network that is based on gigabit Ethernet.
Connects the devices that make up the CENTUM and ProSafe-RS systems.
Network devices such as Layer 2 Switch (L2SW) or Layer 3 Switch (L3SW), and transmission media such as UTP cables or optical fiber cables can be used to set up Vnet/IP.
Reference: TI 30A10A05-01E (Vnet/IP Network Construction Guide) p. 1-2
Ethernet Ethernet communication link between HIS units used to download files from the engineering environment.
Vnet/IP Domain Vnet/IP domain consists of two independent subnets of bus 1 and bus 2. CENTUM VP Domains can have up to 64 stations; the domain address range 1-16. A maximum of 256 stations are allowed per CENTUM VP system.
Example of CENTUM VP System with two (2) domains
In large installations using multi-domains, there is a distinction between the used switches.
Layer 2 Switch (L2SW)
Used for connecting the devices within one (1) Vnet/IP Domain.
Layer 2 switches with 1 Gbps communication speed are used for Vnet/IP.
Level 3 Switch (L3SW)
Used for communications among Vnet/IP domains.
A network switch that has router functions.
If a Vnet/IP consists of multiple domains, the communications are relayed by the layer 3 switches.
Layer 3 switches with 1 Gbps communication speed are used for Vnet/IP.
Reference: IM33J20A10-01EN (Vnet/IP) p. 1-2
As system evolve, it is possible to integrate new systems in the existing installed base.

Example on a plant extension with Vnet and VnetIP Network
Vnet Router The Vnet Router is the hardware dedicated to connect a Vnet/IP domain and a Vnet or a VLnet domain. It can also connect the Vnet domain of the Centum CS. It performs frame conversion and filtering between Vnet/IP and Vnet or between Vnet/IP and VLnet.
Reference: IM33J20A10-01EN (Vnet/IP) p. 1-3
The HIS is a station used mainly for operating and monitoring the process. Although they have the same functionality, their look and feel is quite different. Below you find different examples.

CENTUM VP is licenses driven. Depending on the functional requirement, licenses have to be added. Some examples of package types are shown below:
HIS Package Type
HIS Package name
Standard Operation and Monitoring Function
Multiple-Monitor Support Package
Long-term Data Archive Package
Screen Layout (For Full Screen Mode)
The HIS facilitates the operator monitoring the process. A number of setting are available to optimize the display for the operator. Some settings are:
Number of Frames: Maximum 5 per monitor
Number of Pop-up Window: Maximum 4 per HIS
Maximum 8 per HIS if Multiple-Monitor Support Package is installed
Reference: GS 33J05D10-01EN (VP6H1100) p. 1 and 2
Network Interface Card
For communicating of this operator station in the Vnet/IP a dedicated network card is required.
Example of Vnet/IP card (Model: VI702)
The FCS performs regulatory and sequence control and manages communications with subsystems.
Reference: GS 33J62E10-01EN (A2FV50D) p. 1 and GS 33J15C15-01EN (VP6F1800) p. 6
Parts of Field Control Unit (FCU)
Below you’ll find the layout of the FCU. This unit contains the processor unit.
External Interface Unit
Slots for I/O Modules
Parts of Field Control Station (FCS)
Field Control Unit
Max. Length: 10m
Transmission Speed: 128Mbps
Cable: Cat5e / Single mode fiber optic
Max. Length: 100m (Cat5e)
50km (fiber optic)
Direct Connection (no switch required)
192Mbps (fiber optic)
Node Interface Unit (NIU)
Only for communication modules (ALR111, ALR121, ALF111, etc.)
Cable: twisted pair
N-IO I/O Unit
Reference: GS 33J62E10-01EN (A2FV50D) p. 1 and GS 33J62A10-01EN (N-IO System Overview) p. 4 and 6
Daisy Chain Connection Method
The daisy chain or linear topology is just a number of nodes in series.
N-ESB Bus Coupler Module
16 NIU can be connected per N-ESB Bus Coupler Module and a maximum of 32 NIU per FCS.
Reference: GS 33J62A10-01EN (N-IO System Overview)
Star Connection Method
The star topology is where all nodes connect back to a central node.
Up to 16 NIU (4 modules times 4 ports).
Connection Using Optical ESB Bus
The FCS offers also Optical ESB repeater. This could be used to make a connection between two locations that requires longer length of cable.
Optical ESB Bus Repeater Module
ESB Bus Coupler Module to Optical ESB Bus Repeater Module is connected by ESB bus cable.
For connection using Optical ESB Bus, maximum of 2 NIU per FCU can be configured.
Vnet/IP uses bus 1 for the control communication path. It does not use bus 1and bus 2 alternately. When a problem occurs in bus 1, the communication path switches to bus 2.
However, after bus 1 recovers, the communication path reverts to bus 1. The switching of buses is performed on the respective communication paths that lead to destination.
Reference: TI 30A10A05-01E (Vnet/IP Network Construction Guide) p. 1-9
Vnet/IP Interface for FCS
Addresses for the FCS are set on the back side of the processor module for domain and station. If redundant processors are used, both modules must have the same address.
Vnet/IP Interface for HIS
Because the operator station uses commercial off-the-shelf (COTS) computers, a dedicated network card has to be used in order to connect to the Vnet/IP network. Switches on the card are used to set the domain and station addresses.
The DIP switches for domain number and station number are set here.
Vnet/IP DIP Switch Setting for FCS and HIS
Set the domain/station number by adding the decimal equivalent of the switches turned ON.
Turn ON the Odd Parity Bit (Switch 1) if the number of switches turned ON is even.
Vnet/IP IP Addressing Summary
For Vnet/IP with separate Information Network the following IP addresses are used:
CPU1 – Left CPU
CPU2 – Right CPU
Reference: TI30A10A05-01E (Vnet/IP Network Construction Guide) p. 2-4
Vnet/IP Network Configuration
Below a typical CENTUM VP control network is shown:

Typical configuration that integrates control & safety functionality and asset management
ProSafe-RS (Safety System)
ProSafe-RS is Yokogawa’s process safety system. The ProSafe-RS is connected to the Vnet/IP and its tags and alarms are displayed on the HIS along with all process alarms. The HIS Process Alarm window has filter capabilities specifically designed for safety alarms.
ProSafe-RS is Safety Integrity Level (SIL 3) rated with a single input module, single output module and a single processor. Adding redundant modules does not increase the SIL rating; it increases the hardware “availability”.
Plant Resource Manager (PRM)
PRM is Yokogawa’s “Asset Management” software package. Asset refers to the field devices but specifically the “intelligent” devices such as those with HART, Foundation Fieldbus or Profibus communication.
PRM allows the user to maximize the diagnostic capabilities of the intelligent devices more than a standard control system can do. Maintenance personnel use this tool to see the health of the field devices. It constantly monitors all of the devices on a periodic basis which is user defined.
Field device vendors can create “plug-ins” that are specific to their devices that work with PRM. A valve “plug-in” is calibration software which allows the custom set up of the individual valve. This allows the software to calibrate the valve around the specific dynamics and responses of the valve.
PRM also allows saving of instrument internal configuration which aids in replacement of the device.
I/O Module and Software Address
Example of a process connection to a function block
Example configuration of I/O in the IOM Builder
N-IO I/O Module
The N-IO I/O module converts process input signals into internal data of the FCU and also converts internal data of the FCU into process output signals and sends them to field devices. The N-IO I/O module has analog and digital I/O functions and operates according to the signal type that is defined for each channel.
The available N-IO I/O module is the analog digital I/O module (Model: A2MMM843), which can be mounted on a base plate for adaptor or a base plate for barrier.
