Features
- EDD Availability—An extended device description is available for the DVC6000f digital valve controller. Using this file, any EDD compatible host can provide graphic user interface to the DVC6000f configuration, calibration, and diagnostic capabilities.
- Improved Control—Two-way digital communications give you current valve conditions. You can use this real-time information to make sound process management decisions. By analyzing valve dynamics through AMS ValveLink Software you can identify control areas needing improvement and maintain a high level of system performance.
- Valve and Actuator Data at your Fingertips—Accurate information is the key to valve diagnostics. Valve and actuator spec sheet data for diagnostic use are embedded in the DVC6000f instrument during factory mounting, providing up-to-date and accurate information.
- Enhanced Safety—You can check instrument and valve operation and keep the process running smoothly and safely from a remote location. Access is possible at a field junction box, marshalling panel, or within the safety of the control room using either a 375 Field Communicator, personal computer, or a system workstation. Your exposure to hazardous environments is minimized and you can avoid having to access hard-to-reach valve locations.
- Hardware Savings—DVC6000f Series digital valve controllers, when used in an integrated system, allow you to realize significant hardware and installation cost savings by replacing other devices in the process loop, such as positioners and limit switches, with a FIELDVUE digital valve controller.
- Travel Control-Pressure Fallback—Valve position feedback is critical to the operation of a digital valve controller. Without this feedback, the control valve assembly traditionally goes to its fail safe position. The DVC6000f Series digital valve controller can detect position feedback problems caused by a travel sensor failure or linkage failure and continue to operate in "pressure control" mode.
If a problem with the valve position feedback is detected, the instrument will automatically disable the travel sensor, send an alert, and control it's output pressure much like a fieldbus-to-pressure transducer. This allows the valve assembly to continue to operate with reduced accuracy until maintenance can be scheduled.
- Built to Survive—Field-tough DVC6000f Series digital valve controllers have fully encapsulated printed wiring boards that resist the effects of vibration, temperature, and corrosive atmospheres. A separate weather-tight field wiring terminal box isolates field-wiring connections from other areas of the instrument. Optional stainless steel, remote mount, and extreme temperature constructions provide added durability to any application need.
- Increased Uptime—With the self-diagnostic capability of DVC6000f Series digital valve controllers, you can answer questions about a valve's performance, without pulling the valve from the line. Diagnostics that evaluate the health of the valve assembly, such as instrument supply pressure droop, valve stuck, damaged feedback, friction, deadband analysis and trending, run continuously while the valve is in service and operating. You can also compare the present valve/actuator signature (bench set, seat load, friction, etc.) against previously stored signatures to discover performance changes, before they impact process control.
- Faster Commissioning—The two-way communication capability allows you to quickly commission loops by remotely identifying each instrument, verifying its calibration, reviewing stored maintenance notes, and more.
- Upgrades Made Easy—Using FIELDVUE HotLinkTM technology, firmware upgrades can be downloaded to the DVC6000f instrument over the fieldbus segment wiring, with minimal interruption to process operations. This unique capability lets you take advantage of firmware improvements and increase functionality, while making the upgrade process fast and convenient right from the control room.
- Easy Maintenance—DVC6000f Series digital valve controllers are modular in design. The single module base can be removed from the instrument housing without disconnecting the field wiring, pneumatic connections or stem linkages. This module contains the critical sub-modules so component removal is quick and simple.

- On-Line Friction and Deadband Analysis (see figure 4)
- Friction and Deadband Trending
While all diagnostics can be run while the valve is inline, Performance Diagnostics can be performed while the valve is in service and operating.
Advanced Diagnostics
Advanced Diagnostics include the following dynamic scan tests:
- Valve Signature (see figure 5)
- Dynamic Error Band
- Instrument Drive Signal
These diagnostics are run while the control valve is blocked out and not controlling the process. The diagnostic scans vary the positioner set point at a controlled rate and plot valve operation to determine valve dynamic performance. The valve signature test allows you to determine the valve/actuator friction, bench set, spring rate, and seat load. The Dynamic Error Band test is a combination of hysteresis and deadband plus "slewing." Hysteresis and deadband are static measurements. However, because the valve is moving, a dynamic error, or "slewing" error is introduced.
Dynamic scan tests give a better indication of how the valve will operate under process conditions which are dynamic, not static.
The Step Response Test checks the valve assembly's response to a changing input signal and plots travel versus time. The end results of this test allow you to evaluate the dynamic performance of the valve. The Performance Step Test provides a standardized step test with which to evaluate your valve performance. It utilizes small, medium and large changes.
Advanced Diagnostics are performed with AMS ValveLink Software. The valve must be out of service for Advanced Diagnostics to be performed.
Fieldbus Diagnostics
Fieldbus Diagnostics capabilities include the following diagnostics:
The key valve parameters allow you to monitor the total valve stem travel (travel accumulation) and the number of stem travel reversals (cycles).
- Instrument Health Parameters
The instrument health parameters alert you if there are any problems with the instrument memory, processor, or sensors. Should a problem occur, you can define how the instrument will react to the problem. You can also select which problems will cause the instrument to shutdown. These indicators may be reported as alerts. Monitoring these alerts can give you an instant indication of any problems with the instrument or the valve assembly.
PlantWeb® Alerts
The DVC6000f provides two levels of alerts; Instrument alerts and PlantWeb alerts.
Instrument alerts, when enabled, detect many operational and performance issues that may be of interest. To view these alerts, the user must open the appropriate status screen for a specific device host such as DeltaV, AMS ValveLink Software or a 375 Field Communicator.
Some instrument alerts can also be used to trigger PlantWeb alerts that will be reported in Failed, Maintenance or Advisory categories, as configured by the user (refer to figure 3). PlantWeb alerts, when enabled, are visible through the DeltaV alarm interface tools, such as the alarm banner and the alarm summary object.
When a PlantWeb alert occurs, the DVC6000f sends an event notification and waits a specified period of time for an acknowledgment to be received. This occurs even if the condition that caused the alert no longer exists. If the acknowledgment is not received within the pre-specified time-out period, the event notification is retransmitted. This reduces the possibility of alert messages getting lost.
AMSTM ValveLink® Software
AMS ValveLink Software is a Windows®-based software package that allows easy access to the information available from DVC6000f Series digital valve controllers.
Using AMS ValveLink Software, you can monitor the performance characteristics of the valve and obtain vital information without having to pull the valve from the line. Performance Diagnostic tests, including On-Line Friction, Deadband Analysis and Trending can be run while the valve is in service and operating. Valve Signature, Dynamic Error Band, and Step Response are displayed in an intuitive user-friendly environment that allows easy interpretation of data.
Diagnostic graphs can be superimposed over those previously stored to view areas of valve degradation. This allows plant personnel to concentrate efforts on equipment that needs repair, avoiding unnecessary maintenance. This diagnostic capability is readily accessible and available to you either in the control room or on the plant floor. In addition to the diagnostic features, AMS ValveLink Software contains an Audit Trail, Batch Runner for automating repetitive tasks, and Trending to view valve performance.
AMS ValveLink Software provides integration into AMS and DeltaV, with HART® and Fieldbus communications.
Model 375 Field Communicator
You can perform configuration and calibration at the valve or anywhere on the two-wire loop via a Model 375 Field Communicator (figure 6). Powerful tools such as the Setup Wizard and Auto Travel Calibration automate the tasks of commissioning DVC6000f Series digital valve controllers. These automation tools not only save time, but also provide accurate and repeatable results.
