Fieldbus Redundancy
On January 22, 2001, Yokogawa released the world's first redundant H1 FONDATION fieldbus™ I/O card. Redundant cards are mounted side by side in a chassis, and provide ongoing operation in the event that one card fails. Redundancy or single loop integrity is often specified in operations of many highly critical processes, including the oil & gas and power generation industries. Having redundant I/O cards instead of enforcing single loop integrity will reduce costs and contribute to simplify the system configuration.
4-Channel Fieldbus I/O Cards
On January 22, 2001, Yokogawa released a new FOUNDATION™ I/O card for the CENTUM CS3000 system which has four distinct FOUNDATION fieldbus™ segments. This card reduces rack room space and provides a lower purchase price, especially for large FOUNDATION fieldbus™ systems, while ensuring secure operation by above mentioned redundancy.

Earlier last year, the Fieldbus Foundation™ launched its Host System Interoperability Test Project. The purpose of this project is to improve interoperability between FOUNDATION fieldbus™ instruments and host systems. Recognizing the importance of this testing, Yokogawa offered its CENTUM CS/CS1000/CS3000 systems.
On September 14, 2000, Yokogawa become the first vendor to successfully test against the procedures. This test was conducted in the company's Houston office under the supervision of officials of the Fieldbus Foundation. Yokogawa CENTUM systems are therefore officially recognized by the Fieldbus Foundation as host systems supporting FOUNDATION fieldbus™ technologies in an interoperable manner. |

Yokogawa host systems have communicated with many types of field devices from other manufactures. Up until now, Yokogawa has conducted its own internal procedures and tests items to determine the level of interoperability with each device. The Fieldbus Foundation, early this year, determined to establish a common approach for testing interoperability between hosts and devices, and launched the Host System Interoperability Test (HSIT) project.
Yokogawa recognizes the importance of the HSIT as a key component for total interoperability. Therefore ,Yokogawa fully endorses the HSIT project and has participated extensively in the specification/procedure development.
The HSIT procedure document, as prepared by the HSIT project, is the preliminary specification and is the basis for testing. The procedure specifies how the system supports FOUNDATION™ technologies and determines if it is able to handle Fieldbus devices in an interoperable way. Yokogawa believes this step is very important in achieving the goal of host interoperability.
Thus, Yokogawa reorganized its test procedure according to this document, and has conducted trials using this procedure upon its CENTUM CS/CS1000/CS3000 systems. These trials were to examine whether the project output was useful to improve the interoperability and avoid any interoperability problems in the field.
The second step of the HSIT project is to test various combinations of devices and the hosts. Yokogawa is installing test sites for this purpose and encourages device vendors to join this great FOUNDATION fieldbus™ project. |

Let us help you to learn more about FOUNDATION fieldbus™. Materials on Fieldbus Tutorials are available for your investigation. Links to major fieldbus sites are now available. |
| June 19, 2000 |
Yokogawa has completed ITK 4.0 registration of the first Fieldbus device group with the Fieldbus Foundation. This attests to Yokogawa's commitment to interoperability.
Registered devices are EJA pressure transmitter, YEWFLO vortex flowmeter, ADMAG magnetic flowmeter, YTA temperature transmitter and YVP valve positioner. PID function blocks are available for all of them. |
| April 2000 |
The Fieldbus Foundation is actively improving its interoperability program by completing the specifications for the Communication Profiles and Common File Format (August 1999) and by developing a new R4 Interoperability Test System (April 2000).
Yokogawa is participating in this Interoperability Improvement Project (IIP). Its enhanced EJA and YVP with Link Active Scheduler (LAS) as well as its PID function block have become the first to pass this test.
The Fieldbus Foundation encourages device manufacturers to have their devices retested by this new test system to ensure interoperability.

| April 2000 |
The Yokogawa Fieldbus stack passed the Conformance Test at the Frounhofer Institute in Germany in April 2000.
This new stack has a Link Active Scheduler (LAS) function in addition to the basic field device functions. Yokogawa plans to use it in all coming Yokogawa field devices. |
