First Yamaha Fieldbus chip switches digital factory automation into fast lane; Supports IEC/ISA-SP-50 field bus physical layer; Joint venture with Yokogawa.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Sept. 19, 1995--The next generation of process automation communications is introduced today by Yamaha Systems Technology Inc. with its new YTZ YTZ Toronto, Ontario, Canada (Airport Code) 420 Fieldbus standard LSI LSI: see integrated circuit. (Large Scale Integration) Between 3,000 and 100,000 transistors on a chip. See SSI, MSI, VLSI and ULSI. chip. The new digital chip will replace the previously used 4-20 mA analog system, adding bi-directional capability to field-level communications; permitting remote diagnostics Vehicle Diagnostics Vehicle diagnostics enables a mechanic to diagnose the exact mechanical condition of the vehicle and its systems and components. Remote Diagnostics enables to perform such diagnosis without requiring the vehicle to physically be present for checkup. of field equipment and lowering the cost of communication wiring. Industries using process control such as steel, chemicals, pulp and paper, pharmaceuticals and many others will benefit from this new generation of communication technology. The YTZ420 supports the specifications developed by the Fieldbus Foundation The Fieldbus Foundation is an organization dedicated to a single international, interoperable fieldbus standard. It was established in September 1994 by a merger of WorldFIP North America and the Interoperable Systems Project (ISP). for the process automation industry. These are standard protocols between field equipment on the manufacturing line and the control terminal host. The Fieldbus Foundation is a non-profit organization A non-profit organization (abbreviated "NPO", also "non-profit" or "not-for-profit") is a legally constituted organization whose primary objective is to support or to actively engage in activities of public or private interest without any commercial or monetary profit purposes. made up of manufacturers and developers of equipment designed for industry automation. Their purpose is to establish standard protocols for digital communications Transmitting text, voice and video in binary form. See communications. interfaces for process automation. "This is a clear step forward for process automation," said Bob Starr, general manager, sales and marketing, Yamaha Systems Technology, Inc. "The movement from analog to digital communications is overdue. The costs for field-level communications will go down, while at the same time increasing the capabilities." Product Features Many features make the Yamaha YTZ420 well suited to replace the conventional analog designs. The YTZ420 network controller chip supports the IEC/ISA-SP50 Fieldbus physical link layer and a portion of the data link layer. It supports H1 (31.25 kbps) and H2 (1 Mbps) buses. The H1 bus is synchronous, low speed, between digital field-level devices and the control terminal. The H2 bus is a synchronous high speed bus between the control terminal and the central controller. Using CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology, power consumption is extremely low, making it suitable for both field equipment and controller functions. It interfaces with either Motorola or Intel 8 bit CPUs. It runs on 2.7 to 5.5 volts power, has four kinds of timer and DMA (1) (Digital Media Adapter) See digital media hub. (2) (Document Management Alliance) A specification that provides a common interface for accessing and searching document databases. access support. The product is available in a standard 44 pin quad flat pack (QFP (Quad FlatPack) A square, surface mount chip package that has leads on all four sides and comes in several varieties. PQFP (Plastic QFP) may refer to all of the following QFP types. All quad flatpacks use gull-wing leads, except for the CQFP, which stick straight out. ). Yamaha/Yokogawa Teamwork This product offering is one designed and developed by Yokogawa Electric Corp. Yokogawa Vice President, Kunihiro Murai is a member of the board of Fieldbus Foundation and well experienced in the process automation industry. Yokogawa developed an early version of the YTZ420 in 1993 which it called the FIND1. The YTZ420, also known as the FIND1+ is backward compatible with the FIND1 chip. Yamaha brings its manufacturing, sales and marketing expertise to the agreement. Price and Availability Engineering samples of the YTZ420 are available now. Price for sample quantities is $50. Production quantities will be available in the first quarter of 1996. Yamaha Systems Technology Inc. was founded to manufacture and market integrated circuits, board level products and complete systems to OEMs and VARs. The division's product line includes custom and semi-custom ASICs, standard circuits for graphics, communications and audio applications and CD Recorder products. Yokogawa Electric Corp. is Japan's leading manufacturer of industrial automation equipment and test and measurement instrumentation. The company subsidiary in the U.S. is located in Newnan, Ga. Yokogawa has over 7,000 employees in Japan and more than 4,000 in offices overseas. -0- Note: Fieldbus is a trademark of the Fieldbus Foundation. CONTACT: Yamaha Systems Technology Inc.
