Emerson completes major refinery automation project

A digital automation project recently completed by Emerson Process Management has increased substantially the reliability and performance of the Motiva Enterprises LLC refinery in Norco, LA. Motiva Norco, which processes 225,000 barrels a day of crude oil, is among the largest refineries in the world. Its daily production includes about 10 million gallons of gasoline and about 7 million gallons of jet fuel.

As Main Automation Contractor for the project, Emerson performed engineering, project management, and installation of its PlantWeb digital architecture. At the Motiva refinery, PlantWeb uses FOUNDATION fieldbus to network Emerson's DeltaV digital systems; Rosemount flow, level, pressure, and temperature instruments; and Fisher valves with Fisher Fieldvue digital valve controllers. Predictive diagnostics information is collected by AMS Suite: Intelligent Device Manager, which delivers alarms and data to operations and maintenance personnel.

The project has already yielded results for the facility. These include the company's best-ever reliability utilization year on record, and increased output without adding new units or making the huge investment in money and lead time that would otherwise have been required.

Yokogawa to deliver Fieldbus controls to Shell facility

Two Yokogawa Electric Corp. subsidiaries—Yokogawa System Center Europe and Yokogawa Engineering Asia—are fulfilling an order from Shell Eastern Petroleum (Pte) Ltd. (SEPL) to supply a FOUNDATION fieldbus control system for the Shell Eastern Petrochemicals Complex (SEPC) in Singapore.

SEPL is constructing a new petrochemical plant at SEPC on Singapore's Jurong and Bukom islands. The facility will produce 800 thousand tons of ethylene and 750 thousand tons of mono-ethylene glycol annually. SEPL is also upgrading an existing petroleum refinery with a refining capacity of 500,000 bpd. The new plant will be fully integrated with the existing refinery. The integrated complex is scheduled to start operating in 2009 or 2010.

Yokogawa plans to deliver the control systems, using the latest FOUNDATION technology, by December 2008. These will include the Centum CS 3000 R3 Integrated Production Control System, ProSafe-RS Safety Instrumented System, and Exaquantum Plant Information Management System (PIMS). The company will also deliver DPharp EJX pressure transmitters / differential pressure transmitters.

Teruyoshi Minaki, executive vice president of Yokogawa's International Business Headquarters, said, "We were awarded as Main Automation Contractor because we have the ability to improve the operability and safety of large-scale plants by integrating their production control and safety instrumented systems."

MTL enclosures enhance fieldbus barrier range

MTL's fieldbus barriers provide a reliable and effective means of connecting intrinsically safe fieldbus instruments to H1 networks in Zone 1 and Division 1 hazardous areas. For heavily loaded segments requiring multiple barrier modules, a range of custom field enclosures that suit end-user requirements is available. Optional features include Ex-protected isolating switches that allow individual barrier modules to be removed and replaced without interrupting the operation of other devices on the segment; additional DIN-rail field-wiring terminals; and fixed or switchable terminators. Surge protection may also be specified for the trunk and spurs using MTL's high-performance arrestors, which are designed to operate in fieldbus networks.

A selection of glass-reinforced plastic or stainless steel housings, and a choice of cable glands and blanking plugs in a range of materials, satisfy a variety of environmental conditions. Enclosures accommodating between four and 16 intrinsically safe spurs can be designed and assembled to meet the demanding timescales of today's fieldbus projects.

More information is available by emailing Phil Saward or contacting your local MTL representative.



NI-FBUS now supports Vista fieldbus applications

The NI-FBUS Communications Manager (CM) from National Instruments (NI), which implements a high-level application programming interface (API) to facilitate communication with the NI's FOUNDATION fieldbus communication stack and hardware, now supports Microsoft Windows Vista x 86 in addition to Windows 2000/XP. NI-FBUS CM handles communication between the stack and user applications. It also manages the details of interfacing with the Fieldbus Messaging Specification and with lower layers of the communication stack.

Suppliers can use the NI-FBUS CM API to develop host applications, including, for example, function block tuning software packages and applications for monitoring a function block, diagnosing a network, and developing interfaces to human machine interface (HMI) packages. The NI-FBUS CM API and library support Microsoft Visual C++, Visual Basic, Visual C#, and Visual Basic .Net. NI-FBUS also provides functions and controls for NI LabView palettes.

P+F power hub makes redundancy affordable

FieldConnex High Density (HiD) power hub from Pepperl+Fuchs is a compact 360 mA complement to the company's existing 500 mA FieldConnex device. The HiD offering is a high-performance platform of motherboards and power supplies that uses 25 V to supply up to a 360 mA load output. It is suited for large fieldbus applications requiring redundancy.

The compact HiD power module provides very low heat dissipation of less than 2 W and can be mounted in any direction to give users maximum mounting flexibility and the highest packing density of any competitive product available today. High packing density leads to fewer required cabinets and smaller space requirements in the plant. Standardizing on this new modular solution eliminates additional planning, installation, and commissioning efforts. Passive impedance generation and well-balanced electric circuit design contribute to strong signal quality, smooth and reliable operation, and industry-leading service life.

A choice of motherboards exists to fit any control system, and may be pre-installed using connectors with retaining screws, or tailor-made with system plugs of the DCS. Two power supply modules are load sharing, and can be plugged into the motherboard sockets while the system is energized.

The HiD Power Hub is compatible with Pepperl+Fuchs' Advanced Diagnostic Module (ADM), which provides simplicity and thorough analysis of the fieldbus physical layer. The ADM makes commissioning easy and bridges the gap between manual troubleshooting and automatic diagnosis for easy evaluation of FOUNDATION fieldbus and Profibus installations.

Softing offers new H1 fieldbus device protocol stack

Softing is introducing a new version of its industry-hardened field device protocol stack. Version 2.20 contains a critical mass of new and intriguing features intended to persuade many manufacturers of existing field devices to upgrade their current implementations.

Its main new features include:

  • MultiVariable Container technology that allows the device application to combine multiple variables into a single, logical data-structure (container) and to embed the entire container into a single frame that is transmitted over the fieldbus.
  • Multi-bit Alarms that support applications that require a fine granularity to present alarms with different characteristics or levels by making it possible to generate multi-bit alarms. Softing's protocol stack is designed to be consistent with the official alarm nomenclature defined by NAMUR's Working Group 2.6-Fieldbus NE107, which is also of particular interest for asset management systems.
  • Multi-LAS sub-schedule technology which significantly improves the time management on any give H1 segment by supporting a hierarchical partitioning of the macro-cycle and the individual control of each sub-cycle. This new technology helps to reduce significantly the bus-load for individual field devices by supporting the definition of optimized communication cycles.
  • Improved function block shell interface which allows any vendor to develop and integrate his own function block library easily.

Version 2.20 will be released in the beginning of Q4 2007 and will be available free to any licensee with a maintenance agreement.

R. Stahl introduces 8-spur Ex i fieldbus barrier

R. Stahl's new Ex i field device coupler connects eight, instead of the usual four, intrinsically safe FISCO devices to a fieldbus. The new solution extends R. Stahl's ISbus product range, which consists of components and systems for FOUNDATION technology.

The new 8-spur variants are the same size as previous models. Two 8-spur couplers are sufficient to design fieldbus segments with up to 16 devices. They require half the space and save approximately 20% in costs compared to four conventional 4-spur couplers. The new models retain all the features of R. Stahl's couplers and allow users to choose from such grounding and shielding concepts as single point, multiple point, and capacitive grounding. The units feature an integrated, switchable terminator. They come with unique power management that reduces starting currents in the trunk and, in case of short-circuits in several spurs, minimizes fault currents in the bus. Signal and error status are signalized via LEDs.

The new field device couplers are suitable for use in Zone 1, Zone 2 and U.S. Div. 2. They are available with plastic or stainless steel housings, which can be tailored to customer requirements.

TopWorx valve controllers cut installation costs

Because TopWorx understands that the cost of a FOUNDATION fieldbus installation is driven by segment requirements, the company has designed valve controllers that reduce the number of needed segments. TopWorx valve controllers require only one function block, while traditional devices need at least three to handle two switch inputs and a solenoid output.

By requiring fewer function blocks, the TopWorx valve controllers create a domino effect that leads to significant cost savings throughout the entire installation. For example:

1. Fewer blocks mean quicker device execution time per segment;
2. Quicker device execution time means more devices per segment;
3. More devices per segment mean fewer segments;
4. Fewer segments lead to reduced hardware and software licensing costs; and
5. Reduced costs mean real savings.

Users that choose TopWorx can expect a reduction in the amount of H1 cards, power supplies, and power conditioners, and in their annual software support costs. TopWorx, a recognized leader in on/off valve control for FOUNDATION fieldbus, offers free re-configured module templates and faceplates. The company reports it was the first supplier to introduce an on/off valve controller for FOUNDATION fieldbus and has eight years experience implementing these products in process environments.
