Using Latest IT Technology

Benefiting from IT advances through introduction of general-purpose IT technology– Varied network equipment can be selected

depending on the application.• Optical transmission units for ultra-long distances,

explosion-proof adapters, etc.• Free from the limitation of YNT

– Use of commercially available network equipment can also improve cost flexibility.

– Highly flexible networks can be designed.

Page.38


Highly Reliable and Real-time Communication

Enabling communication suitable for control systems with high reliability, and real-time speed. – Realizing a communication incorporating field-proven

Vnet functions.– Redundant configuration and quick bus switching are

available.– Establishing a close connection with Vnet through Vnet

routers.

Integration of Non-CENTUM Components

Both open and control communication data can be transferred on the 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.

Note that this configuration requires a hub.

Page.40


Improved Communication Performance

Thanks to improved communication performance, the maximum number of stations can literally be connected in a single domain—no more restrictions—facilitating system expansion.– Eliminating use of master coefficients– The number of connectable HIS units are not

limited unlike with Vnet.– An increasing number of HMI units have been

connected in a single system, including some systems with more than 16 units. With Vnet/IP, connecting many HIS units does not cause domains to be divided.

Page.41


The former tokuchu SEM (Sequence of Events Manager) is now available as standard function for Vnet/IP FCS.– Features

• Achieving SOE function with 1-ms resolution through a DI module that has been developed exclusively for SOE and can be ordered as a standard module.

• Vnet/IP systems do not use dedicated Ethernet for SOE, which is required for SOE event collection in a Vnet configuration.

• Stations can synchronize their clocks with each other with an accuracy of 1 ms without an external master clock.

Detecting Detailed Network Statuses

Vnet based systems have a special network monitoring tool. But this tool is not open to customers.Vnet/IP systems, even without a tool, detailed statuses of networks can be obtained. If network trouble occurs, customers can get detailed information, greatly reducing the length of plant shutdown periods.

Vnet/IP internal

For security of communication– Effective measures

• Distinctively secured connection• Entirely wrapped conduit• Well spread processing load

To maintain deterministic– Special devices

• Very specific transport layer• Well designed dedicated ASIC

For more detail, see ISD-MASP-S05037.pdf put on ‘IA-DCS-Technical Information’ on global cyber

Page.50


Why secure? (contd.)

Distinctively secured connection– Encryption mechanism– Maintaining the individuality of each

connection

Against "Disguise" and "Falsification"

Page.51



Entirely wrapped conduit– Vnet protocol embedded on IP– Vnet protocol itself proprietary

Against "Tapping"

Page.52



Well spread processing load– Dedicated processor for communication

Against “Denial of Service”

Page.53


Why deterministic?

Very specific transport layer– Periodic time synchronization with 100 ms

cycle• Each cycle divided into 1 ms time slot• Jitter within 100 micro seconds

– Very precise scheduling

Time sharing network

Page.54


Why deterministic? (contd.)

Well designed dedicated ASIC– Prioritizing packet as per ToS (Type of

Service)– Allotting packet from PHY to FIFO directly

distance communication – Network costs of Vnet and

Vnet/IP are almost equal.(for transfer price based CENTUM components.)

Network Cost Comparison (2)

• 52 HIS/ENG + 54 FCS• 12 domains

– Network cost of Vnet/IP is 10 to 15% lower than that of Vnet. (for transfer price based CENTUM components)

Page.62


Points that Require Attention

Vnet/IP is Ethernet based, so the following points require attention: – Network engineering is required. – Max. length of UTP cable is shorter than

Vnet cable. Cascade connection of L2SW or optical fiber extension may be required.

– Network devices are resale products. Procurement work is important. Regularly check information for YHQ recommended devices.

Page.63

other manufacturers on a project basis.– Service and warranty will be provided by

manufacturers.

– CISCO 3750G : Specific models will be announced later.

– Note that as these hubs are installed at temperatures in office environments as opposed to CENTUM components, exercise care to ensure satisfactory installation conditions.

Page.65



Long-distance communication equipment– Media converters

• Used for connection with fiber optic cables for long-distance communication

• Selected models: Pending

– Note that Vnet/IP does not require arresters which are essential for protection of outdoor network wiring, as fiber optic cables are recommended for Vnet/IP’s outdoor wiring.

Page.66



Cables– General use cables

• Used for short-distance and intra-domain networks• Cable specification: CAT5e (with RJ45 connectors)• Length: 100 m

– Fiber optic cables• Used for long-distance networks• Cable specification: Single mode• Length: 5 km for single-core 1000Base-LX cables.
