The Fieldbus Center at Lee College (Baytown, TX) is preparing for the final acceptance test (FAT) for the hybrid batch demonstration at the BP chemical plant in Lima, OH. More than 15 member companies are participating in this demo, which is intended to illustrate a multiple-vendor solution.
The BP Lima, OH, processing plant is the first comprehensive, world-class implementation of Flexible Function Blocks (FFBs) in a hybrid batch chemical processing plant. At an event scheduled for May 19, industry trade press representatives, Fieldbus Foundation Board of Directors and Executive Committee members, End User Council team leaders, and engineering personnel will see a working demonstration of the plant. Table top displays showcasing FOUNDATION fieldbus products will emulate the demonstration.
The BP demonstration applies a high-speed plant backbone implementation over H1 and HSE level fieldbus devices with FFBs to create a high performance plant interface. The implementation provides a comprehensive solution setting the stage for 2005 and beyond with future process control integration.

ABB has been awarded a project worth over $4.7 million to provide the entire automation and instrumentation suite for Petro-Canada's De Ruyter oil and gas production platform. The project is the first new-build offshore platform to use FOUNDATION fieldbus. It will also use ABB's new System 800xA high integrity safety controller (SIS).
De Ruyter production platform is to be built in the North Sea some 60 km offshore from The Hague. ABB will deliver the automation and instrumentation systems in August 2005; the platform is scheduled to come on-stream in mid 2006. Awarded against a competitive tender, ABB won the contract for its ability to produce the whole system as a single package. The company and Petro-Canada will work closely on the design as an integrated team.
The installation is based on the 800xA extended automation system and includes a control and safety system based on the ABB AC800M and AC800HI safety controllers (SIS), FOUNDATION fieldbus for process control, and HART for other control and safety I/O. ABB will also supply all field instrumentation, including pressure and temperature transmitters, flow elements, level transmitters, and magnetic flow meters, many of which will be the company's own FOUNDATION fieldbus and HART-compliant devices.
ABB began work on the project immediately after receiving the award. Key requirements are guaranteed performance and the ability to control design changes.

Emerson Process Management has won a $3.1 million contract for the digital automation and control of minerals processing at the BHP Billiton nickel/cobalt mine and treatment facility under construction in Ravensthorpe, Australia. The new open-pit mine and minerals processing plant is part of a $1.1 billion project that will annually produce up to 50,000 tons of nickel and 1,400 tons of cobalt.
Emerson will install its PlantWeb® digital architecture with FOUNDATION fieldbus technology to deliver significantly more process and equipment information than traditional analog systems. The system will let BHP Billiton operate a safer, more reliable, and better performing mine and plant.
The DeltaV digital automation system with AMS Suite predictive maintenance software, key components of PlantWeb, are at the core of the innovative digital approach that will include more than 2,000 smart digital field devices. Emerson reports that the project is the largest FOUNDATION fieldbus installation in Australia, and the largest for mineral processing in the world.
PlantWeb enables manufacturers to avoid costly, unexpected process interruptions and optimize performance of production equipment by establishing a predictive maintenance environment that is anchored by digital monitoring of instrumentation and equipment condition using data from smart field devices.

TrunkGuard device couplers are now available in intrinsically safe forms (TG100 Series) with versions suitable for direct drive using Hawke's RM100 I.S. power supply or anyone else's FISCO power supply. Hawke calls the RM100 the class leader for I.S. applications, providing 350 mA capacity per segment, power supply redundancy, built-in surge protection, and IIC devices. FISCO systems are available capable of 115mA in IIC and 250mA in IIB, but with surge protection and power supply redundancy only as external options.
Hawke's TrunkGuard technology protects fieldbus segments from spur short-circuits. It "switches off" faulty spurs with automatic resetting on fault removal; other designs simply limit current per fault, but at levels which often force segments into overload shutdown or cause internal damage unless spur problems are immediately addressed.
TG200 is intended for general purpose and non-incendive systems (Zone2/Div2), and TG300 is the solution for Zone1, allowing Exd devices to be individually disconnected while the rest of the segment remains under power with no interruption to other measurement and control points, and no need for local gas detection on field maintenance.
For fieldbus segment power and device protection with any preferred protection techniqueHawke Fieldbus provides the best solution.

MTL-Relcom has introduced a range of intrinsically safe fieldbus barriers, adding to its extensive portfolio of fieldbus power supplies and wiring components. Together with MTL-Relcom's FISCO power supplies, the new units allow MTL to provide the best technical solution and lowest cost for every IS fieldbus application.
Each Zone-1-mounted barrier unit supports four intrinsically safe spurs, for connection to "Entity" or FISCO-certified fieldbus instruments in IIB or IIC, Zone 0 hazardous areas. Multiple fieldbus barriers may be connected on the fieldbus trunk, which is installed as increased safety (Ex e) wiring. The barrier units are compatible with the MTL-Relcom FPS range of redundant power supplies, including integrated power systems for all major fieldbus control system vendors.
Available in glass reinforced polyester or stainless steel enclosure options, the 9301-FB and 9302-FB have excellent chemical and moisture resistance, and are suitable for installation in a wide range of corrosive environments. The 9302-FB unit may be powered from a locally available ac or dc supply, reducing the current drawn from the trunk and increasing the trunk cable length and number of devices supported per trunk to full FOUNDATION fieldbus limits.

StoneL has compiled a new wall poster that illustrates FOUNDATION fieldbus H1 wiring practices using explosion proof, nonincendive, and intrinsically safe protection concepts. NEC 500 code practices are illustrated, along with a broad array of StoneL wiring components and field instruments for assembling a complete FF H1 network in division 1 and 2 hazardous environments.
At-a-glance wall poster is an excellent reference tool when designing a FOUNDATION fieldbus H1 network.

Yokogawa's H1 interface card is helping mitigate the "macro-cycle factor" that limits the number of devices on a segment by supporting sub-schedules within the macro-cycle. By providing up to four sub-schedules, fast acting loops can now exist on the same segment as a slow-acting loop, increasing the number of devices supported per segment.
The physical layer of FOUNDATION fieldbus is designed for up to 32 devices per H1 segment. Practically, however, the H1 interface card in most systems limits the actual number of devices supported per segment. The increasing capability of richer, more capable fieldbus devices may limit the number of devices per segment due to macro-cycle execution time.
In current implementations, all function blocks in a segment must execute at the basic scan of the macro-cycle. Fast scan and slow scan function blocks cannot execute on the same segment, limiting the functionality of the fieldbus implementation and segment layout.
The H1 interface card provides the solution. A requirement of one fast executing loop of 250 ms with several slow executing loops running one second, and additional monitoring devices running at 2 to 5 seconds, is easily accomplished with the implementation of four sub-schedules. In addition, the four sub-schedule system provides a friendly environment that enhances the types and number of function blocks, along with the number of devices and their mix.
