FVP Fieldbus Valve Positioner

Transcription

1 FVP Fieldbus Valve Positioner Dresser Flow Control enters the new and exciting era of digital communicating valve positioning devices. This document offers information on the most advanced digital communications valve positioners currently available. Jointly developed with our partner, Yokogawa, the FVP is fully compliant, tested and registered with FOUNDATION Fieldbus. Page 1 of 6

2 The Evolution of DFC Positioners While FOUNDATION fieldbus retains many of the desirable features of the 4-20 ma analog system, such as a standardized physical interface, bus-powered devices, and intrinsic safety options, it offers a host of additional benefits to users. Device Interoperability With interoperability, one fieldbus device can be replaced by a similar device with added functionality from a different supplier on the same fieldbus network while maintaining specified operations. This permits users to "mix and match" field devices and host systems from various suppliers. Individual fieldbus devices can also transmit and receive multivariable information, and communicate directly with each other over a common fieldbus, allowing new devices to be added to the fieldbus without disrupting active control. Enhanced Process Data With FOUNDATION fieldbus, multiple variables from each device can be brought into the plant control system for archival, trend analysis, process optimization studies, and report generation. This access to accurate, high resolution data enables processes to be fine-tuned for better manufacturing throughput and reduced plant downtime. These efficiencies add up to higher plant performance and profitability. Expanded View of the Process Modern fieldbus devices, with powerful, microprocessor-based communications capabilities, permit process errors to be recognized faster, and with greater certainty. As a result, plant operators are notified of abnormal conditions or the need for preventive maintenance, and can make better production decisions. Problems that detract from operating efficiency are more quickly corrected, enabling yields to go up while raw material costs and regulatory problems decrease. Page 2 of 6

3 Improved Plant Safety Fieldbus technology will help manufacturing plants keep up with increasingly stringent safety requirements. By providing operators with earlier notification and warning of pending and current hazardous conditions, fieldbus allows for corrective action before an unplanned shutdown. Enhanced plant diagnostic capabilities also reduce the need for frequent access to hazardous areas, thus minimizing the risks to field personnel. Easier Predictive Maintenance Enhanced device diagnostics capabilities make it possible to monitor and record such conditions as valve wear and transmitter fouling. Plant personnel are able to perform predictive maintenance without waiting for a scheduled shutdown, thus avoiding or reducing downtime. Reduced Wiring & Installation Costs FOUNDATION fieldbus' use of existing wiring and multi-drop connections provides significant savings in network installation costs. This includes reductions in intrinsic safety barrier termination and cable costs, particularly in areas where wiring is already in place. Additional cost savings can be achieved through the decreased time required for construction and start-up, as well as simplified programming of control and logic functions using software control blocks built into fieldbus devices. According to current estimates, there are now FOUNDATION fieldbus systems in operation in more than 25 countries around the world. The FVP will serve as DFC's FF digital positioner platform. Offered initially in four configurations: with and without pressure sensors for advanced diagnostics, with or without PID functionality. The FVP is extremely powerful with six function blocks and 488 user selectable parameters. FVP Function Blocks Provide High Performance and Flexibility Page 3 of 6

5 ValVue FF 1.0 ValVue FF is an exciting and revolutionary Human-Machine Interface (HMI) product that significantly advances the art of dealing with field instruments. Based on the highly successful ValVue 2.0 for HART the easy to use, intuitively obvious screen structures are enhanced with set up wizards that allow the user to rapidly setup and calibrate the FVP. ValVue - FF is packaged with National Instruments NI FBUS Configurator software for soft-wiring and scheduling activities as well a PCMCIA FF Network Interface Card. This combination thereby offers the user all the tools the tools required for configuration, commissioning, startup, operation and diagnostics of valving in one complete and powerful package. ValVue - FF Provides a single, powerful overview screen with icon or menu driven access to all functions. Easy Configuration Easy to Use Calibration Simple or Advanced Tuning Screens Page 5 of 6

6 Function Block Analysis Advanced capabilities for Function Block analysis, softwiring and microprocessor scheduling are also included. Self checking diagnostics, easy to use Setup Wizard's and a nine hour storable / retrievable trend window are all designed for fast, accurate and effective management of the FVP.
