The FIELDVUE DVC6200f Digital Valve Controller is a core component of the PlantWeb™ digital
plant architecture. The digital valve controller powers PlantWeb by capturing and delivering valve
diagnostic data. Coupled with ValveLink™ software, the DVC6200 provides users with an accurate
picture of valve performance, including actual stem position, instrument input signal, and
pneumatic pressure to the actuator. Using this information, the digital valve controller diagnoses
not only itself, but also the valve and actuator to which it is mounted.

Instrument Blocks
The digital valve controller is a block‐based device. For detailed information on the blocks within the digital valve
controller, see the Detailed Setup section of this manual.
The DVC6200f digital valve controller includes the resource and transducer block:
Resource Block—The resource block contains the hardware specific characteristics associated with a device; it has
no input or output parameters. The resource block monitors and controls the general operation of other blocks
within the device. For example, when the mode of the resource block is Out of Service, it impacts all function
blocks.
Transducer Block—The transducer block connects the analog output function block to the I/P converter, relay, and
travel sensor hardware within the digital valve controller.
Function Blocks
In addition to the resource and transducer block, the digital valve controller may contain the following function blocks.
For additional information on function blocks, refer to Appendix D, F
OUNDATION fieldbus Communication.
Analog Output (AO) Function Block—The analog output function block accepts the output from another function
block (such as a PID block) and transfers it as an actuator control signal to the transducer block. If the DO block is
selected, the AO block is not functional.
Proportional‐Integral‐Derivative (PID) Function Block—The PID function block performs
Input Selector (ISEL) Function Block—The input selector function block selects from up to four inputs and may
provide the selected signal as input to the PID block. The input selection can be configured to select the first good
input signal; a maximum, minimum or average value; or a hot spare.
Output Splitter (OS) Function Block—The output splitter function block accepts the output from another function
block (such as a PID block) and creates two outputs that are scaled or split, according to the user configuration. This
block is typically used for split ranging of two control valves.
Analog Input (AI) Function Block—The analog input function block monitors the signal from a DVC6200f sensor or
internal measurement and provides it to another block.
Multiple Analog Input (MAI) Function Block—The Multiple Analog Input (MAI) function block has the ability to
process up to eight DVC6200f measurements and make them available to other function blocks.
Discrete Output (DO) Function Block—The discrete output function block processes a discrete set point and sends it
to a specified output channel, which can be transferred to the transducer block for actuator control. In the digital
valve controller, the discrete output block provides both normal open/closed control and the ability to position the
valve in 5% increments for course throttling applications. If the AO block is selected, the DO block is not functional.
Discrete Input (DI) Function Block—The discrete input function block processes a single discrete input from a
DVC6200f and makes it available to other function blocks. In the digital valve controller, the discrete input function
block can provide limit switch functionality and valve position proximity detection.

WARNING
Personal injury or property damage caused by fire or explosion may occur if this connection is attempted in a potentially
explosive atmosphere or in an area that has been classified as hazardous. Confirm that area classification and atmosphere
conditions permit the safe removal of the terminal box cap before proceeding.
Install a jumper across the SIMULATE ENABLE terminals to enable the instrument to accept a simulate command.
(These terminals are marked AUX on the terminal board, see figure 2‐2). With the jumper in place and the simulate
parameter in the AO or DO block set to enabled, the transducer block ignores the output of the AO or DO block. The
simulate value and status become the readback value and status to the AO or DO block and the transducer block is
ignored. For more information on running simulations, see the Detailed Setup section of this manual, the
fieldbus specifications, and the host documentation.
WARNING
Removing the jumper will disable the simulate, which may cause the valve to move. To avoid personal injury and property
damage caused by the release of pressure or process fluid, provide some temporary means of control for the process.

WARNING
Changes to the instrument setup may cause changes in the output pressure or valve travel. Depending on the application,
these changes may upset process control, which may result in personal injury or property damage.
When the DVC6200f digital valve controller is ordered as part of a control valve assembly, the factory mounts the
digital valve controller and sets up the instrument as specified on the order. When mounting to a valve in the field, the
instrument needs to be setup to match the instrument to the valve and actuator.
Before beginning basic setup, be sure the instrument is correctly mounted as described in the Installation section.
Basic Setup includes the following procedures:
Device Setup
Auto Travel Calibrate
Performance Tuner (Optional)
Note
The DVC6200f may keep the Transducer Block Mode Out‐of‐Service if the instrument is not properly mounted.
To setup and calibrate the instrument, the Transducer Block Mode must be Manual, and the Protection must be None.
When using DD methods the method will request that you change the mode, but make changes in Protection automatically. If you
have a host system that overrides transducer block parameters ensure that the Protection setting is not
result in transducer block parameters being overwritten.
To setup and calibrate the instrument, the transducer block mode must be in Manual. For more information about
transducer block mode, refer to page 38.

Instruction Manual
D103412X012
Typically Device Setup determines the required setup information based upon the actuator manufacturer and model
specified. However, if you enter OTHER for the actuator manufacturer or the actuator model, then you will be
prompted for setup parameters such as:
Actuator Style—Select spring & diaphragm, piston double‐acting without spring, piston single‐acting with spring,
piston double‐acting with spring.
Valve Style—Select the valve style, rotary or sliding‐stem.
Zero Power Condition—this identifies whether the valve is fully open or fully closed when the input is 0%. If you are
unsure how to set this parameter, disconnect the instrument from the segment. (With double‐acting and
single‐acting direct digital valve controllers, disconnecting the instrument from the segment is the same as setting
the output A pressure to zero. For single‐acting reverse digital valve controllers, disconnecting the instrument from
the segment is the same as setting the output B pressure to supply.)
WARNING
If you answer YES to the prompt for permission to move the valve when setting the Travel Sensor Motion, the instrument
will move the valve through its full travel range. To avoid personal injury and property damage caused by the release of
pressure or process fluid, isolate the valve from the process and equalize pressure on both sides of the valve or bleed off the
process fluid.
Travel Sensor Motion—Device Setup asks if it can move the valve to determine travel sensor motion. If you answer
Yes, the instrument will stroke the valve the full travel span to determine travel sensor motion. If you answer No,
then you must specify the direction of travel movement. For quarter‐turn actuators determine rotation by viewing
the rotation of the magnet assembly from the back of the instrument.
Note
Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be
referred to as a magnetic array in user interface tools.
For instruments with relay A or C If increasing air pressure at output A causes the magnet assembly to move up, or
the actuator shaft to rotate counterclockwise, enter “Towards Top of Instrument/CCW.” If it causes the magnet
assembly to move down, or the actuator shaft to rotate clockwise, enter “Away From Top of Instrument/CW.” For
instruments with relay B.
For instruments with relay B If decreasing air pressure at output B causes the magnet assembly to move up, or the
actuator shaft to rotate counterclockwise, enter “Towards Top of Instrument/CCW.” If it causes the magnet
assembly to move down, or the actuator shaft to rotate clockwise, enter “Away From Top of Instrument/CW.”
Note
Relay A adjustment may be required before Device Setup can determine travel sensor motion. Follow the prompts on the Field
Communicator display if relay adjustment is necessary.
Table 3‐2 lists the required Travel Sensor Motion selections for Fisher and Baumann actuators.

Tuning Set—There are twelve tuning sets to choose from. Each tuning set provides a preselected value for the digital
valve controller gain settings. Tuning set C provides the slowest response and M provides the fastest response. For
smaller actuators use tuning set C or D. For larger actuators using tuning set F or G. Table 3‐3 lists the values for
preselected tuning sets.

WARNING
Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury or property damage
caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.
In addition, you can select Expert, which allows you to individually set the proportional gain, velocity gain, and minor
loop feedback gain for travel tuning and pressure proportional gain, pressure integrator gain, and pressure minor loop
feedback gain for pressure tuning. Refer to page 39 for additional information on travel tuning and page 41 for
pressure tuning.
Note
Use Expert tuning only if standard tuning has not achieved the desired results.
Stabilize/Optimize or Performance Tuner may be used to achieve the desired results more rapidly than expert tuning.
Table 3‐2 provides tuning set selection guidelines for Fisher and Baumann actuators. These tuning sets are only
recommended starting points. After you finish setting up and calibrating the instrument, use Stabilize/Optimize to
adjust the tuning set to get the desired response.

Instruction Manual
D103412X012
When Device Setup is complete you are asked if you wish to run Auto Calibration now. Select yes to automatically
calibrate instrument travel at this time. Follow the prompts on the Field Communicator display. The calibration
procedure uses the valve and actuator stops as the 0% and 100% calibration points. For additional information, refer to
Auto Calibration in the Calibration section.
Note
Single‐acting relay B and C are not user‐adjustable. However, it is recommended that you check the relay adjustment for
double‐acting relay A in new installations before proceeding with travel calibration.
Refer to page 191 for relay adjustment instructions.
If after completing setup and calibration the valve cycles or overshoots (unstable), or is unresponsive (sluggish), you
can improve operation by running Performance Tuner or Stabilize/Optimize.
Performance Tuner
Field CommunicatorTB > Configure/Setup > Basic Setup > Performance Tuner
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.
The Performance Tuner is used to determine digital valve controller tuning. It will move the valve slightly and monitor
the effects of small tuning changes until an optimum control response is achieved. Because the Performance Tuner
can detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning
more effectively than manual tuning. Typically, the Performance Tuner takes 3 to 5 minutes to tune an instrument,
although tuning instruments mounted on larger actuators may take longer.

Section 4 Detailed Setup4-4-
Resource Block
Overview
The resource block contains the hardware specific characteristics associated with a device; it has no input or output
parameters. The resource block monitors and controls the general operation of other blocks within the device. Most of
the resource block parameters are operational parameters that provide information about the instrument such as
identification, hardware information, available options, etc. and are read only. Configuration of the resource block
involves selecting features from those that are available, setting the mode, setting write lock, and setting up alert
reporting details.
The following procedures address only the key resource block parameters; however, all resource block parameters are
listed in table 4‐3.
Configure/Setup
Setup
Resource Block Mode
Field CommunicatorRB > Configure/Setup > Setup > Resource Block Mode
Modes
The resource block can be in one of two modes (MODE_BLK [5]):
Automatic (Auto)—This is the operational mode for this block. When the resource block is in the Auto mode, all
other function blocks are allowed to function normally.
Out of Service (OOS)—Placing the resource block in Out of Service mode stops all function block execution, by
setting their modes to Out of Service as well. The actual mode of the function blocks is changed to Out of Service, but
the function block target modes are retained. Placing the resource block in the Out of Service mode does not affect
the mode of the transducer block.
Write Lock
Field CommunicatorRB > Configure/Setup > Write Lock
Write Lock
Write Lock (WRITE_LOCK [34]) determines if writes are permissible to other device parameters. The Firmware Write
Lock feature must be selected to be able to use Write Lock (see Features). When Write Lock is set to Locked, no writes
are permitted to any parameters within the device except to set Write Lock to Not Locked. When locked, the device
functions normally, updating inputs and outputs and executing algorithms. When Write Lock is set to Not Locked, the
Write Alarm (WRITE_ALM [40]) alert is active.

January 2015
Instruction Manual
D103412X012
Write Priority
Write Priority (WRITE_PRI [39]) sets the priority for Write Alarm. The lowest priority is 0. The highest is 15.
Communication Time Out
Field CommunicatorRB > Configure/Setup > Communication Time Out
Shed Remote Cascade
Note
Typically this parameter does not need to be changed. The unit will be operational using the default values assigned by the factory.
Perform this procedure only if a remote computer is sending setpoints from your “advanced” control.
Default value for RCas Timeout is 20 seconds.
Shed Remote Cascade (SHED_RCAS [26]) determines how long function blocks in the DVC6200f should wait before
giving up on remote computer writes to RCas parameters. When the timeout is exceeded, the block sheds to the next
mode as defined by the block shed options. If Shed Remote Cascade is set to 0, the block will not shed from RCas.
Enter a positive value in the Shed Remote Cascade field. Time duration is in 1/32 milliseconds (640000
= 20 secs).
Shed Remote Out
Note
Typically this parameter does not need to be changed. The unit will be operational using the default values assigned by the factory.
Perform this procedure only if a remote computer is sending setpoints from your “advanced” control.
Default value for Shed Remote Out is 20 seconds.
Shed Remote Out (SHED_ROUT [27]) determine how long function blocks in the DVC6200f should wait before giving
up on computer writes to ROut parameters. When the timeout is exceeded, the block sheds to the next mode as
defined by the block shed options. If Shed Remote Out is set to 0, the block will not shed from ROut. Enter a positive
value in the Shed Remote Out field. Time duration is in 1/32 milliseconds (640000
= 20 secs).

for this resource.
Data Type: Unsigned32
Time duration of the shortest cycle interval (in
1/32 millisecond) of which the resource is
capable. In the digital valve controller this value
is fixed at 3200 (100 milliseconds).
Date Type: Unsigned16
Memory, in kilobytes, available for additional
function blocks. Because no additional function
blocks may be added to DVC6200f instruments,
this parameter value is fixed at 45.
Date Type: Unsigned32
This parameter identifies the minimum time
interval (in 1/32 milliseconds) between copies of
NV class data to NV memory. NV memory is
updated only if there has been a change in the
dynamic value. The last value saved in NV
memory will be available for the restart
procedure or a power cycle. A non‐zero value
regulates the frequency of writes, thus
protecting the life span of the device. If the value
is zero, data will never be automatically copied.
Changes made by other than publishing to NV
parameters will be copied to non‐volatile
memory immediately. For DVC6200f
instruments, this parameter value is fixed at
576,000 (18 seconds).
Data Type: Float
Percent of memory available for additional
function blocks (see also MEMORY_SIZE).
Because no additional function blocks may be
added to DVC6200f instruments, this parameter
value is fixed at 0.
Data Type: Float
Percent of block processing time that is free to
process additional blocks. Because no additional
function blocks may be added to DVC6200f
instruments, this parameter value is fixed at 0.
Date Type: Unsigned32
Time duration (in 1/32 millisecond) at which to
give up on computer writes to function block
RCAS parameters. If this time is exceeded then
the function block will change to a mode other
than RCAS based on the SHED_OPT parameter
setting. Shed from RCAS mode never happens
when SHED_RCAS is set to zero.
Data Type: Unsigned32
Time duration (in 1/32 millisecond) at which to
give up on computer writes to function block
ROUT parameters. If this time is exceeded then
the function block will change to a mode other
than ROUT based on the SHED_OPT parameter
setting. Shed from ROUT mode never happens
when SHED_ROUT is set to zero.
Data Type: Unsigned8
Forces output function blocks that are not Out
of Service to the fault state condition. While this
parameter is active the output function blocks
will go to an actual mode of Local Override (LO)
and will perform their fault state actions (see
Action On Fault Detection for the output blocks
on pages 94 and 170 of this section). This
parameter is used to test the fault state behavior
that normally occurs when there is a
communication problem between devices. This
parameter is changed by the SET_FSTATE and
CLR_FSTATE parameters so long as the feature
Fault State is selected (see Feature Selection
[index number 18] in this table).
Data Type: Unsigned8
Selecting Set changes the parameter
FAULT_STATE to Active. This is essentially a
“write only” parameter as it will always read OFF
because it is defined as momentary. Writing a
value of OFF has no affect. To use this parameter
the feature Fault State must be selected (see
Features Selected on page 23).
Data Type: Unsigned8
Selecting Clear changes the parameter
FAULT_STATE to Clear and clears the output
function blocks of the FAULT_STATE if the field
condition, if any, has cleared. This is essentially a
“write only” parameter as it will always read OFF
because it is defined as momentary. Writing a
value of OFF has no affect. To use this parameter
the feature Fault State must be selected (see
Features Selected on page 23.
Data Type: Unsigned8
The maximum number of alert reports that this
device can send without getting a confirmation.
To control alert flooding, the number can be set
lower by adjusting the LIM_NOTIFY parameter
value. For DVC6200f instruments, this value is
fixed at 3.
Data Type: Unsigned8
The number of alert reports that this device can
send without getting a confirmation up to the
maximum permitted in the parameter
MAX_NOTIFY. If set to zero, then no alerts are
reported.
Data Type: Unsigned32
The time (in 1/32 millisecond) the device waits
for confirmation of receipt of an alert report
before trying again.

View Lists
View lists allow the values of a set of parameters to be accessed at the same time. Views 1 and 2 contain operating
parameters and are defined by the Fieldbus Foundation. View 3 contains dynamic parameters and View 4 contains
static parameters with configuration and maintenance information. Views 3 and 4 are defined by the manufacturer.
The transducer block accepts a signal from an output block as a set point to position a valve using a pneumatic
actuator. Input to the transducer block is in percent. Closed is 0%, and open is 100%. The transducer block contains
setup and calibration information and can be tuned to closely match the actuator. Input characterization permits
modifying the overall characteristic of the instrument‐actuator‐valve combination in order to modify the installed gain
characteristic of the loop. The transducer block can also be used to perform instrument and valve diagnostics and
trigger performance alerts.
The following procedures address only the key transducer block parameters; however, all transducer block parameters
are listed in table 4‐14.
Detailed Setup
Note
To setup and calibrate the instrument, the transducer block Mode must be Manual and the Protection must be None.
The transducer block can be in one of three modes (MODE_BLK [5]):
Automatic (Auto)— This is the normal mode for this block. When the transducer block is in the auto mode, it accepts
the output from the AO or DO block as a set point and outputs a drive signal to the I/P converter based upon this set
point.
Out of Service (OOS)— Placing the transducer block in Out of Service mode changes the output to the zero power
(no I/P drive) condition.
Field Communicator
Manual (MAN)— Placing the transducer block in Manual will hold the value at the current setpoint (FINAL_VALUE
[13]). The transducer block will not accept changes from the AO or DO blocks. This mode is required to change some
parameters and to run some diagnostics.
Protection
Field CommunicatorTB > Configure/Setup > Detailed Setup > Protection
To configure any parameters in the digital valve controller Write Lock (WRITE_LOCK [34]), in the resource block, must
be set to Unlocked (refer to page 21). In addition, protection is provided for various transducer block parameters, as

indicated in the Protect Category column of table 4‐14, to prevent inadvertently overwriting key data by the host
system or user.
All— will protect all transducer block Parameters.
Setup and Calibration— will protect only Setup and Calibration transducer block parameters.
Calibration— will protect only Calibration transducer block parameters.
None— will not protect any transducer block parameters.
Note
The Device Setup Auto Travel and Manual Travel methods automatically change transducer block protection for the user.
See table 4‐14 for individual parameter details.

Travel Tuning
Field CommunicatorTB > Configure/Setup > Detailed Setup > Response Control > Travel Tuning
WARNING
Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury or property damage
caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.
Travel Tuning Set—There are eleven Travel Tuning Sets (TVL_TUNING_SET [42.10]) to choose from. Each tuning set
provides a preselected value for the digital valve controller gain settings.
Tuning set C provides the slowest response and M provides the fastest response. Table 4‐8 lists the proportional gain,
velocity gain and minor loop feedback gain values for preselected tuning sets.
In addition, you can specify Expert tuning and individually set the proportional gain, velocity gain, and minor loop
feedback gain. Individually setting or changing any tuning parameter or running the Performance Tuner or
Stabilize/Optimize will automatically change the tuning set to X (expert).

Instruction Manual
D103412X012
Table 3‐2 provides tuning set selection guidelines for Fisher and Baumann actuators. These tuning sets are
recommended starting points. After you finish setting up and calibrating the instrument, you may have to select either
a higher or lower tuning set to get the desired response.
For an actuator not listed in table 3‐2, you can estimate a starting tuning set by calculating the casing or cylinder
volume. Then, find an actuator in table 3‐2 with the closest equivalent volume and use the tuning set suggested for
that actuator.
Travel Proportional Gain—Travel Proportional Gain (SERVO_GAIN [18]) is the proportional gain for the travel control
tuning set. Changing this parameter will also change the tuning set to Expert.
Travel Velocity Gain—Travel Velocity Gain (SERVO_RATE [20]) is the velocity gain for the travel control tuning set.
Changing this parameter will also change the tuning set to Expert.
Travel MLFB Gain—Travel MLFB Gain (TVL_MLFB_GAIN [44.5]) is the minor loop feedback gain for the travel control
tuning set. Changing this parameter will also change the tuning set to Expert.
Travel Integral Enable—Travel Integral Enable (TVL_INTEG_ENABLE [44.1]) is used to enable the integral setting to
improve static performance by correcting for error that exists between the travel target and actual travel.
Travel Integral Gain—Travel Integral Gain (SERVO_RESET [19]) (also called reset) is the ratio of the change in output
to the change in input, based on the control action in which the output is proportional to the time integral of the
input.
Travel Integral Dead Zone—Travel Integral Dead Zone (TVL_INTEG_DEADZ [44.4]) is a window around the Primary
Setpoint in which the integral action is disabled. The dead band is configurable from 0 to 2%.
Travel Integral Limit Hi—Travel Integral Limit Hi (TVL_INTEG_LIM_HI [44.2]) provides an upper limit to the integrator
output. The high limit is configurable from 0 to 100% of the I/P drive signal.
Travel Integral Limit Lo—The Travel Integral Limit Lo (TVL_INTEG_LIM_LO [44.3]) provides a lower limit to the
integrator output. The low limit is configurable from -100 to 0% of the I/P drive signal.
Performance Tuner
WARNING
During performance tuning the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.
Performance Tuner is used to determine digital valve controller tuning. It will move the valve slightly and monitor the
effects of small tuning changes until an optimum control response is achieved. Because the Performance Tuner can
detect internal instabilities before they become apparent in the travel response, it can generally optimize tuning more
effectively than manual tuning.
Stabilize/Optimize
WARNING
During Stabilize/Optimize the valve may move, causing process fluid or pressure to be released. To avoid personal injury
and property damage caused by the release of process fluid or pressure, isolate the valve from the process and equalize
pressure on both sides of the valve or bleed off the process fluid.

D103412X012
Detailed Setup—Transducer Block
January 2015
If after completing initial setup and calibration the valve cycles or overshoots, or is sluggish, you can improve
operation by running Stabilize/Optimize.
Stabilize/Optimize is included with the device description (DD) firmware. Stabilize/Optimize is accessible from the
transducer block and permits changing the transducer block set point a small amount to see if the valve is unstable or
unresponsive. If valve response is unsatisfactory, the method permits adjusting the digital valve controller tuning to
improve response.
If the valve is unstable, select Decrease Response to stabilize valve operation. This selects the next lower tuning set
(e.g., F to E). If the valve response is sluggish, select Increase Response to make the valve more responsive. This selects
the next higher tuning set (e.g., F to G).
If after selecting Decrease Response or Increase Response the valve travel overshoot is excessive, Increase Damping or
Decrease Damping can be used to select a damping value not represented in a predefined tuning set. Select Decrease
Damping to select a damping value that allows more overshoot. Select Increase Damping to select a damping value that
will decrease the overshoot.
When valve operation is satisfactory, select Exit. Before exiting, you are asked if you want to return the transducer
block mode to Auto. Select Yes to change the transducer block mode to Auto. Select No to leave the transducer block
in its current mode.
Pressure Tuning
Field CommunicatorTB > Configure/Setup > Detailed Setup > Response Control > Pressure Tuning
WARNING
Changes to the tuning set may cause the valve/actuator assembly to stroke. To avoid personal injury or property damage
caused by moving parts, keep hands, tools, and other objects away from the valve/actuator assembly.
Pressure Tuning Set
There are twelve Pressure Tuning Sets (PRESS_TUNING_SET [42.11]) to choose from. Each tuning set provides a
preselected value for the digital valve controller gain settings.
Tuning set C provides the slowest response and M provides the fastest response. Tuning set B is appropriate for
controlling a pneumatic positioner. Table 4‐9 lists the proportional gain, pressure integrator gain and minor loop
feedback gain values for preselected tuning sets.
In addition, you can specify Expert tuning and individually set the pressure proportional gain, pressure integrator gain,
and pressure minor loop feedback gain. Individually setting or changing any tuning parameter will automatically
change the tuning set to X (expert).

necessary to enable the Travel Sensor Alert for Pressure Fallback to occur.
Travel Deviation Pressure Fallback—Travel Deviation Pressure Fallback occurs when the instrument detects that the
travel sensor is outside of its normal range of operation or that a gross deviation exists between set point and actual
travel. It switches to Pressure Control and no longer uses the travel sensor to position the valve.
Travel Cutoff Hi—Travel Cutoff Hi (FINAL_VALUE_CUTOFF_HI [15]) defines the high cutoff point for the travel in
percent (%) of pre‐characterized setpoint. Above this cutoff, the travel target is set to 123.0% of the ranged travel.
Travel Cutoff Hi is deactivated by setting it to 125.0%.
Travel Cutoff Lo—Travel Cutoff Lo (FINAL_VALUE_CUTOFF_LO [16]) defines the low cutoff point for the travel in
percent (%) of pre‐characterized setpoint. Below this cutoff, the travel target is set to -23%. A Travel Cutoff Lo of
0.5% is recommended to help ensure maximum shutoff seat loading. Travel Cutoff Lo is deactivated by setting it to
-25.0%
Pressure Cutoff Open—Pressure Cutoff Open (PRESS_CUTOFF_HI [47.1]) defines the high cutoff point for the
pressure in percent (%) of pre‐characterized setpoint. Above this cutoff, the pressure target is set to 123.0%. A
Pressure Cutoff Open of 99.5% is recommended to ensure valve goes fully open. Pressure Cutoff Hi is deactivated by
setting it 125%.
Pressure Cutoff Closed—Pressure Cutoff Closed (PRESS_CUTOFF_LO [47.2]) defines the low cutoff point for the
pressure in percent (%) of pre‐characterized setpoint. Below this cutoff, the pressure target is set to -23%. A Pressure
Cutoff Closed of 0.5% is recommended to help ensure maximum shutoff seat loading. Pressure Cutoff Closed is
deactivated by setting it to -25.0%
Pressure Range Hi—Pressure Range Hi (PRESS_RANGE_HI [42.7]) is the high end of output pressure range. Enter the
pressure that corresponds with 100% valve travel when Zero Power Condition is closed, or 0% valve travel when
Zero Power Condition is open. This pressure must be greater than the Pressure Range Lo.
Pressure Range Lo—Pressure Range Lo (PRESS_RANGE_LO [42.8]) is the low end of the output pressure range. Enter
the pressure that corresponds to 0% valve travel when Zero Power Condition is closed, or 100% valve travel when
Zero Power Condition is open. The pressure must be less than the Pressure Range Hi.

Alerts
The DVC6200f provides two levels of alerts; Instrument alerts and PlantWeb alerts.
Instrument Alert Conditions
Instrument Alert Conditions, 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 on a host such as DeltaV, ValveLink software or
a Field Communicator.
PlantWeb Alerts
Some instrument alert conditions can also be used to trigger PlantWeb alerts that will be reported in Failed,
Maintenance or Advisory categories, as configured by the user. PlantWeb alerts, when enabled, can participate in the
DeltaV alarm interface tools such as the alarm banner, alarm list and alarm summary.
When a PlantWeb alert occurs, the DVC6200f 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.
PlantWeb alerts are mode‐based. Refer to table C‐1 for details.
Note
Additional details on setting up and using PlantWeb Alerts can be found in Appendix C of this manual.

matches the actuator travel range.
Note
As a general rule, do not use less than 60% of the magnet assembly travel range for full travel measurement. Performance will
decrease as the assembly is increasingly subranged.
The linear magnet assemblies have a valid travel range indicated by arrows molded into the piece. This means that the hall sensor
(on the back of the DVC6200f housing) has to remain within this range throughout the entire valve travel. The linear magnet
assemblies are symmetrical. Either end may be up.

Travel Sensor Motion (TRAVEL_SEN_MOTION [42.3]) establishes the proper valve travel sensor (feedback)
rotation/movement. For quarter‐turn actuators determine rotation by viewing the rotation of the magnet assembly
from the back of the instrument.
Note
Travel Sensor Motion in this instance refers to the motion of the magnet assembly. Note that the magnet assembly may be
referred to as a magnetic array in user interface tools.
For instruments with relay A or C If increasing air pressure at output A causes the magnet assembly to move up, or the
actuator shaft to rotate counterclockwise, enter “Towards Top of Instrument/CCW.” If it causes the magnet assembly
to move down, or the actuator shaft to rotate clockwise, enter “Away From Top of Instrument/CW.” For instruments
with relay B.

View Lists
View lists allow the values of a set of parameters to be accessed at the same time. Views 1 and 2 contain operating
parameters and are defined by the Fieldbus Foundation. View 3 contains dynamic parameters and View 4 contains
static parameters with configuration and maintenance information. Views 3 and 4 are defined by the manufacturer.
The Analog Output (AO) function block (figure 4‐6) assigns an output value to a field device through a specified I/O
channel. The block supports mode control, signal status calculation, and simulation. Figure 4‐7 illustrates the internal
components of the AO function block, and table 4‐25 lists the definitions of the block parameters. The digital valve
controller measures and uses actual valve position for READBACK [16].

Modes
The Analog Output function block supports the following modes:
Manual (Man)—You can manually set the output to the I/O channel through the OUT [9] attribute. This mode is used
primarily for maintenance, calibration and diagnostics.
Automatic (Auto)—The block output (OUT [9]) reflects the target operating point specified by the setpoint (SP [8])
attribute. Typically the setpoint is set by the user.
Cascade (Cas)—The SP [8] attribute is set by another function block through a connection to CAS_IN [17]. The SP [8]
value is used to set the OUT [9] attribute automatically. This is the most frequently used mode in the digital valve
controller.
Note
The transducer block must be in Auto for the mode to go to AUTO, CAS, MAN, or RCAS.
RemoteCascade (RCas)—The SP [8] is set by a host computer by writing to the RCAS_IN [28] parameter. The SP [8]
value is used to set the OUT [9] attribute automatically.
90
Page 93
Instruction Manual
D103412X012
Out of Service (OOS)—The block is not processed. The output channel is maintained at the last value and the status
of OUT [9] is set to Bad: Out of Service. The BLOCK_ERR [6] attribute shows Out of Service.
Initialization Manual (Iman)—The path to the output hardware is broken and the AO block output will remain at the
last position. This means the transducer block mode is Out of Service or Manual or configured to respond to the DO
block.
Local Override (LO)—The output of the block is not responding to inputs because the fault state action is active. OUT
[9] freezes or goes to value per IO_OPTS [14].
The target mode of the block may be restricted to one or more of the following modes: Man, Auto, Cas, RCas, or OOS.

Mode Handling
Shed Options—RCAS Mode Only
Automatically changing through the permitted modes when starting from a remote mode, fall from (or shed) or climb
to a remote mode is determined by the parameter SHED_OPT [27]. A block climbs and sheds through the same path.
For example, if SHED_OPT [27] specifies that a block should shed to Auto, then, if the block target mode is set to RCas,
the block goes through Auto on the way to RCas.
When the block is in Cas mode and the CAS_IN [17] input goes bad, the block sheds mode to the next lower permitted
mode.
You can configure the shed option as follows:
Shed With Return Options
Remote cascade connection failure shifts actual mode but keeps trying to restore remote cascade (in other words, the
remote cascade target mode stays in effect).
Note
During Shed with Return Options, the actual mode is changed, while the target mode stays the same.
Normal—On failure of a remote cascade connection the block attempts to attain the highest permitted non‐remote
mode until remote cascade is restored. Cas is the highest permitted non‐remote mode and Auto is is the next
permitted non‐remote mode. If Cas or Auto are not available, the block will shed by default to Man.
Retained Target—The retained target mode is the previous target mode before it was changed to RCAS or ROUT. On
failure of a remote cascade connection the block attempts to attain the retained target mode.
Auto—On failure of a remote cascade connection the block attempts to attain Auto, if permitted, until remote cascade
is restored.
Man—On failure of a remote cascade connection the block sheds to Man until a remote cascade connection is
restored.
Shed With No Return Options
Note
During Shed with No Return Options, the target mode is changed, while the actual mode stays the same.
91
Page 94
Detailed Setup—AO Function Block
January 2015
For any shed with no return option, the target mode changes as determined by the option. Therefore, there is no
attempt to restore the connection following failure. The behavior on change to the remote cascade target mode is
identical to that for Shed With Return Options.
Normal—On failure of a remote cascade connection the block sets the target mode to the highest permitted
non‐remote mode. Cas is the highest permitted non‐remote mode and Auto is is the next highest permitted
non‐remote mode. If Cas or Auto are not available, the block will shed by default to Man.
Retained Target—The retained target mode is the previous target mode before it was changed to RCAS or ROUT. On
failure of a remote cascade connection the block sets the target mode to the retained target mode.
Auto—On failure of a remote cascade connection, the block sets the target mode to Auto, if permitted.
Man—On failure of remote cascade connection, the block sets the target mode to Man, if permitted.
The user may configure SHED_OPT [27] so that it calls for a target mode that is not permitted. When doing this, the
mode logic uses the following rules as applied by the remote logic:
Shed logic never results in a non‐permitted target mode.
Shed logic never attempts to attain an actual mode of Auto or Cas if that mode is not permitted.
Instruction Manual
D103412X012
Status Handling
Output or readback fault detection is reflected in the status of PV [7], OUT [9], and BKCAL_OUT [25]. A limited SP [8]
condition is reflected in the BKCAL_OUT [25] status. When simulation is enabled through the SIMULATE [10] attribute,
you can set the value and status for PV [7] and READBACK [16].
When the block is in Cas mode and the CAS_IN [17] input goes bad, the block sheds mode to the next permitted
mode.
Setting the Output
To set the output for the AO block, you must first set the mode to define the manner in which the block determines its
setpoint. In Manual mode the value of the output attribute (OUT [9]) must be set manually by the user, and is
independent of the setpoint. In Automatic mode, OUT [9] is set automatically based on the value specified by the set
point (SP [8]) in engineering units and the I/O Options attribute.In addition, you can limit the SP [8] value and the rate
at which a change in the SP [8] is passed to OUT [9].
In Cascade mode, the cascade input connection (CAS_IN [17]) is used to update the SP [8]. The back calculation
output (BKCAL_OUT [25]) is wired to the back calculation input (BKCAL_IN [27]) of the upstream block that provides
CAS_IN [17]. This provides bumpless transfer on mode changes and windup protection in the upstream block.
Note
You must wire BKCAL_OUT [25] to BKCAL_IN [27] of the upstream block that provides CAS_IN [17]. Otherwise, the AO will not
initialize properly, and the setpoint at CAS_IN [17] will not be passed to OUT [9].
An analog readback value, such as valve position, is shown by the process value (PV [7]) attribute in engineering units.
To support testing, you can enable simulation, which allows you to manually set the channel feedback. There is no
alarm detection in the AO function block.
92
Page 95
Instruction Manual
D103412X012
To select the manner of processing the SP and the channel output value configure the setpoint limiting options, the
tracking options, and the conversion and status calculations.
Detailed Setup—AO Function Block
January 2015
Output Block PV Status
The Output Block PV Status is determined by the value of the PlantWeb Alerts Set PV Status parameter in the
transducer block (PWA_SET_STATUS [97]), the Transducer Block mode, and enabled Active PlantWeb alarms. Refer to
table 4‐11.
Set Point Selection and Limiting
To select the source of the SP [8] value use the MODE [5] attribute. In Automatic (Auto) mode, the local,
manually‐entered SP [8] is used. In Cascade (Cas) mode, the SP [8] comes from another block through the CAS_IN [17]
input connector. In RemoteCascade (RCas) mode, the SP [8] comes from a host computer that writes to RCAS_IN [28].
The range and units of the SP [8] are defined by the PV_SCALE [11] attribute.
In Manual (Man) mode the SP [8] automatically tracks the PV [7] value when you select the SP‐PV Track in Man I/O
option in IO_OPTS [14]. This option can be used to minimize valve movement when the AO block is transitioned from
Manual mode to Auto. You can disable this option in OOS mode only.
The SP [8] value is limited to the range defined by the setpoint high limit attribute (SP_HI_LIM [20]) and the setpoint
low limit attribute (SP_LO_LIM [21]).
In Auto mode, the rate at which a change in the SP [8] is passed to OUT [9] is limited by the values of the setpoint
upward rate limit attribute (SP_RATE_UP [19]) and the setpoint downward rate limit attribute (SP_RATE_DN [18]). A
limit of zero disables rate limiting.
As shown in figure 4‐8, the block executes a percentage of the set point change each macrocycle. For example, if the
set point rate is set at 10% per second and the macrocycle is 500 milliseconds (0.5 seconds or 50% of 1 second), then
during the first macrocycle the set point will change 5% (50% of the 10% per second rate). If the macrocycle is 750
milliseconds (0.75 seconds or 75% of 1 second), then during the first macrocycle the setpoint will change 7.5% (75% of
10).
When the transducer block receives the setpoint change from an AO block with rate limits, it will smoothly move the
valve to the requested setpoint at the rate limit configured in the AO block.
In Auto mode, the converted SP [8] value is stored in the OUT [9] attribute. In Man mode, the OUT [9] attribute is set
manually, and is used to set the analog output defined by the CHANNEL [22] parameter.
You can access the actuator position associated with the output channel through the READBACK [16] parameter (in
OUT units) and in the PV [7] attribute (in engineering units). The digital valve controller supports position feedback
and therefore provides the actual valve position in PV [7] and READBACK [16] directly.

Action On Fault Detection
To define the action you wish the valve to take when the block is in CAS mode, and the CAS_IN [17] input detects a
communication failure, or is commanded to go to fault state by the upstream block or the resource block, configure
the following parameters:
IO_OPTS [14]: Determines the action OUT [9] will take upon a fault state. If the IO_OPTS [14] “Fault State to Value” is
not selected, then OUT [9] holds its last position when Fault State is set. If “Fault State to Value” is selected, OUT [9]
goes to the FSTATE_VAL [24] value when Fault State is set.
FSTATE_TIME [23]: The length of time, in seconds, that the AO block will wait to set Fault State. When Fault State is
set, the OUT [9] value goes to either the FSTATE_VAL [24] value or holds its last position, depending on I/O_OPTS [14].
When the block has a target mode of CAS, a fault condition will be detected if the CAS_IN [17] has a BAD status or an
Initiate Fault State substatus is received from the upstream block.
FSTATE_VAL [24]: Determines the OUT [9] value if IO_OPTS “Fault State to Value” is selected. The OUT [9] value
transitions to FSTATE_VAL [24] after FSTATE_TIME [23] elapses and the fault condition has not cleared.
I/O Options
The I/O options parameter (IO_OPTS [14]) allows you to select how the I/O signals are processed. You can set I/O
options in Out of Service mode only. The following I/O options are available in the AO block:
Use PV for BKCAL_OUT—Changes the BKCAL_OUT [25] value to the PV [7] value. When the Use PV for BKCAL_OUT
option is not enabled (False), the BKCAL_OUT [25] value is the working setpoint value.
Target to Man if Fault State Activated—Set the target mode to Man, thus losing the original target, if Fault State is
activated. This latches an output block into the manual mode.
94
Page 97
Instruction Manual
D103412X012
Use Fault State value on Restart—Use the value of FSTATE_VAL [24] for SP [8] when power is restored or if the device is
restarted, otherwise use the last value saved in non‐volatile memory. This does not act like Fault State, it only uses the
value of FSTATE_VAL [24].
Fault State to Value—The output action to take when a fault occurs (if not selected, use hold last value; if selected, use
FSTATE_VAL [24]).
Increase to Close—If the Increase to Close bit is set the value to the transducer is inverted, e.g. 20% becomes 80%.
SP-PV Track in Man—Permits the setpoint to track the process variable when the target mode of the block is MAN.
SP-PV Track in LO or IMan—Permits the setpoint to track the process variable when the actual mode of the block is LO
or IMan.
SP Track retained Target—Permits the setpoint to track the RCas or Cas parameter based on the retained target mode
when the actual mode of the block is LO or Man. When SP‐PV track options are enabled, the SP Track retained target
will have precedence in the selection of the value to track when the actual mode is Man and LO.
Detailed Setup—AO Function Block
January 2015
Simulation
When simulate is active, the transducer sub‐parameters show the actual transducer block status and value as normally
passed back to the AO block. The Simulate sub‐parameters are writable and replace actual transducer values.
Note
When simulate is active, the output block no longer writes values to the transducer block. If the Output Blk Timeout period is
exceeded, the transducer block may move the valve to the Zero Power Condition depending on the configuration of the Output
Block Timeout Alert.
Application Information
The configuration of an AO function block and its associated output channels depends on the specific application. A
typical configuration for the Analog Output involves the following attributes:
PV_SCALESet the range and engineering units to values that correspond to the operation range.
For the digital valve controller, PV_SCALE [11] is typically set between 0 and 100%.
BKCAL_OUTIf you are using the CAS_IN [17] connector wired from another block, wire the
BKCAL_OUT [25] attribute to the other block's BKCAL_IN [27] attribute.
IO_OPTSSet the type of tracking and action upon fault state.
SHED_OPTSet the action to be taken when the set point or output are not updated in a remote
mode.
