Control Network Vnet/IP
New control network, Vnet/IP
Use the Latest Information Technology
| Benefit from advances in IT by using the latest general-purpose equipment. |
| |
- |
A variety of network devices can be selected depending on the application. |
| |
|
|
- |
Optical transmission units for ultra-long distances, explosion-proof adapters, etc. |
| |
|
|
- |
Free from the limitation of using Yokogawa's own bus repeater |
| |
- |
The use of commercially available network devices reduces costs. |
| |
- |
Highly flexible networks can be designed. |
 |
Highly Reliable Real-time Communications
| Enabling communication suitable for control systems with high reliability, and real-time speed. |
| |
- |
Communication incorporating field-proven V net functions |
| |
- |
Redundant configuration and quick bus switching
|
| |
- |
Close connection with V net via V net routers |
 |
Integration of Non-CENTUM Components
| Both open and control communication data can be transferred via Vnet/IP, enabling the configuration of a platform that facilitates a future integration of the open and control communications.
|
| |
- |
Enabling non-CENTUM components to be connected. |
 |
Improved Communication Performance
| Thanks to improved communication performance, there is no restriction as to the maximum number of stations that can be connected in a single domain, facilitating system expansion. |
| |
- |
The use of master coefficients has been eliminated. |
| |
- |
Unlike V net, there is no limit to the number of HIS units that can be connected. |
| |
- |
The number of HMI units that are being connected in systems is on the increase, with some systems now reporting 16 units or more. With Vnet/IP, the connection of large numbers of HIS units does not cause domains to be divided. |
Detecting Detailed Network Statuses
| - |
With Vnet/IP systems, detailed network status information can be obtained even without the use of special tools. If a network failure occurs, customers can get detailed information and greatly reduce the length of a plant shutdown. |
Station Status Window
| - |
Displays change depending on the network configuration |
| - |
Failure location detection is easier than with V net |
| |
 |
Domain Status Window
| - |
Displays status information on communications between domains |
