1. Notes on Handling
1-1
The YVP110 advanced valve positioner is fully
factory-tested upon shipment. When the YVP110 is
delivered, visually check that no damage occured
during the shipment.
1.1 Nameplate
The model name and conguration are indicated
on the nameplate. Verify that the conguration
indicated in the “Model and Sufx Code” in Chapter
7 is in compliance with the specications written on
the order sheet.
F0101.ai
Figure 1.1 Nameplate
1.2 Transport
To prevent damage while in transit, leave the
positioner in the original shipping container until it
reaches the installation site.
(3) The performance of the positioner may be
impaired if stored in an area exposed to direct
rain and water.
To avoid damage to the positioner, install it
immediately after removal from the shipping
container. Follow wiring instructions in this
manual.
1.4 Choosing the Installation
Location
Although the advanced valve positioner is
designed to operate in a vigorous environment,
to maintain stability and accuracy, the following is
recommended:
(1) Ambient Temperature
It is preferable not to expose the instrument
to extreme temperatures or temperature
uctuations. If the instrument is exposed to
radiation heat a thermal protection system and
appropriate ventilation is recommended.
(2) Environmental Requirements
Do not allow the positioner to be installed
in a location that is exposed to corrosive
atmospheric conditions. When using the
positioner in a corrosive environment, ensure
the location is well ventilated. The unit and its
wiring should be protected from exposure to
rainwater.
1.3 Storage
When an extended storage period is expected,
observe the following precautions:
(1) If at all possible, store the positioner in factory-
shipped condition, that is, in the original
shipping container.
(2) Choose a storage location that satises the
following requirements.
• A location that is not exposed to rain or water.
• A location subject to a minimum of vibration or
impact.
• The following temperature and humidity range
is recommended. Ordinary temperature and
humidity (25°C, 65%) are preferable.
Temperature: –40 to 85°C
Humidity: 5 to 100% RH (at 40°C)
(3) Impact and Vibration
It is recommended that the positioner is
installed in a location that is subject to a
minimum amount of impact and vibration.
1.5 Use of a Transceiver
Although the positioner is designed to resist
inuence from high frequency noise, use of a
transceiver in the vicinity of installation may cause
problems. Installing the transmitter in an area free
from high frequency noise (RFI) is recommended.
IM 21B04C01-01E

1.6 Insulation Resistance Test
and Withstand Voltage Test
CAUTION
(1) Overvoltage of the test voltage that is so
small that it does not cause an dielectric
breakdown may in fact deteriorate insulation
and lower the safety performance; to prevent
this it is recommended that the amount of
testing be kept to a minimum.
(2) The voltage for the insulation resistance test
must be 500V DC or lower, and the voltage
for the withstand voltage test must be 500V
AC or lower. Failure to heed these guidelines
may cause faulty operation.
(3) Where a built-in arrester is provided (sufx
code: /A), the voltage for the insulation
resistance test must be 100V DC or lower,
and the voltage for the withstand voltage test
must be 100V AC or lower. Failure to heed
these guidelines may cause faulty operation.
Withstand voltage test procedure
Testing between the input terminals and the
grounding terminal
1. Lay the transition wiring between the + terminal
and the − terminal, and connect the withstand
voltage tester (with the power turned OFF)
between the transition wiring and the grounding
terminal. Connect the grounding side of the
withstand voltage tester to the grounding
terminal.
2. After setting the current limit value of the
withstand voltage tester to 10 mA, turn
the power ON, and gradually increase the
impressed voltage from 0 V to the specied
value.
3. The voltage at the specied value must remain
for a duration of one minute.
4. Upon completion of the test, carefully reduce
the voltage so that no voltage surge occurs.
1.7 Notes for Saftey
Follow the steps below to perform the test, the
wiring of the communication line must be removed
before initiating testing.
Insulation resistance test procedure
1. Lay transition wiring between the + terminal and
the − terminal.
2. Connect the insulation resistance meter (with
the power turned OFF) between the transition
wiring of Step 1 above and ground terminal.
The polarity of the input terminals must be
positive and that of the ground must be
negative.
3. Turn the power of the insulation resistance
meter ON and measure the insulation
resistance. The duration of the applied voltage
must be the period during which 100 MΩ
or more is conrmed (or 20 MΩ if the unit is
equipped with a built-in arrester).
4. Upon completion of the test, remove the
insulation resistance meter, connect a 100
kΩ resistor between the transition wiring, and
allow the electricity to discharge. Do not touch
the terminal with your bare hands while the
electricity is discharging for more than one
second.
CAUTION
When air is supplied to a valve, do not touch
the moving part (a stem of the valve), as it may
suddently move.
CAUTION
• While A/M selection switch is set to manual
side (M), the pressure set in the regulator
for air supply will be directly output to the
actuator regardless of the control signal.
Before changing the mode from auto to
manual, check and conrm thoroughly that
there will be no effect which may cause
a danger in process or personal injury by
changing the mode.
• Do not change the mode by using auto/
manual switch during the operation. If the
mode is changed from auto to manual or
manual to auto, the valve stem will happnen
to move to the position which is different
from the control signal (the input signal to the
positioner), and thus dangerous.
• As soon as the manual operation is nished,
make it sure to change the mode to auto by
moving the A/M selection switch to Auto(A)
side.

Note 4. FISCO rules
The FISCO concept allows the interconnection
of intrinsically safe apparatus to associated
apparatus not specically examined in
such combination. The criterion for such
interconnection is that the voltage (Ui), the
current (Ii) and the power (Pi) which intrinsically
safe apparatus can receive and remain
intrinsically safe, considering faults, must be
equal or greater than the voltage (Uo, Voc,
Vt), the current (Io) and the power (Po) which
can be provided by the associated apparatus
(supply unit). In addition, the maximum
unprotected residual capacitance (Ci) and
inductance (Li) of each apparatus (other than
the terminators) connected to the eldbus
must be less than or equal to 5 nF and 10 µH
respectively.
In each I.S. eldbus segment only one active
source, normally the associated apparatus, is
allowed to provide the necessary power for the
eldbus system. The allowed voltage Uo of the
associated apparatus used to supply the bus is
limited to the range of 14 V d.c. to 24 V d.c. All
other equipment connected to the bus cable
has to be passive, meaning that the apparatus
−+
F0102.ai
is not allowed to provide energy to the system,
except to a leakage current of 50 µA for each
connected device.
Supply unit
trapezoidal or rectangular output characteristic
only
Uo = 14 to 24 V (I.S. maximum value)
Io according to spark test result or other
assessment,
e.g. 133 mA for Uo = 15 V (Group IIC, rectangular
characteristic)
No specication of Lo and Co in the
certicate and on the label.
Cable
The cable used to interconnect the devices
needs to comply with the following parameters:
loop resistance R’: 15 to 150 Ω/km
inductance per unit length L’: 0.4 to 1 mH/km
capacitance per unit length C’: 80 to 200
nF/km
C’ = C’ line/line + 0.5 C’ line/screen, if both
lines are oating
or
C’ = C’ line/line + C’ line/screen, if the screen
is connected to one line
length of spur cable: max. 30 m (Group IIC)
or 120 m (Group IIB)
length of trunk cable: max. 1 km (Group IIC)
or 1.9 km (Group IIB)
Terminators
At each end of the trunk cable an approved
line terminator with the following parameters is
suitable:
R = 90 to 100 Ω
C = 0 to 2.2 µF
The resistor must be infallible according to IEC
60079-11. One of the two allowed terminators
might already be integrated in the associated
apparatus (bus supply unit).
System evaluation
The number of passive devices like
transmitters, actuators, hand held terminals
connected to a single bus segment is not
limited due to I.S. reasons. Furthermore, if the
above rules are respected, the inductance
and capacitance of the cable need not to be
considered and will not impair the intrinsic
safety of the installation.

3.1 General
For installation of a YVP110, see Section 1.4,
“Choosing the Installation Location.” For the
ambient, environmental conditions required
for installation, see Chapter 7, “General
Specications.”
WARNING
To avoid injury or the process being affected
when installing or replacing a positioner on a
control valve, ensure that:
• All inputs to the valve actuator and other
accessories of the valve and actuator,
including the air supply and electric signal,
are cut off.
• The process has been shut down or the
control valve is isolated from the process by
using bypass valves or the like.
• No pressure remains in the valve actuator.
3.2.1 Installing YVP110 on Linear-motion
Control Valve
The following shows the general installation
procedure when assembling a YVP110 with a
linear-motion control valve (e.g., a globe valve)
combined with a diaphragm actuator or cylinder
actuator. Note that the most suitable procedure
may differ depending on the shapes of the bracket
and valve actuator, and the structure of the
mounting position.
3.2 Installing YVP110 on
Actuator
A YVP110 can be installed on a valve actuator with
a mounting bracket. Prepare the bracket and clamp
which are necessary to install the valve, according
to the valve. In general, the installation method is
determined by the combination of the control valve
and positioner as well as by the valve manufacturer
who performs the adjustment. For details, consult
the control valve manufacturer.
Required Tools: To install a YVP110, you need to
prepare:
• Nominal 13-mm open end or box end wrench
for M8 bolts used to x the mounting bracket to
the positioner.
• Nominal 10-mm open end or box end wrench
for M6 bolt used to x the feedback lever to the
shaft.

(2) Fixing the YVP110 to Actuator with Bracket
After xing the bracket to the YVP110, attach it
to the actuator with the specied bolts.
Depending on the shapes of the bracket and
actuator, the working space at the rear of the
YVP110 where the feedback shaft is positioned
may be quite narrow, making installation work
tricky. In such a case, the entire procedure
may be made much easier by attaching
the feedback lever to the feedback shaft as
described in step (3), prior to carrying out step
(2). Check the space behind the YVP110
beforehand.
(3) Attaching Feedback Lever
The YVP110 with option code /LV1 comes with
two different feedback levers, (1) and (2) shown
below, and the one with option code /LV2
comes with lever (3). Check the specications
of the levers shown in Table 3.1 and Figure
3.2 and choose the lever most suitable for the
control valve used.

When combining a YVP110 with a rotarymotion actuator, ensure that the rotation of the
feedback shaft by the position feedback meets
the following specications:
• Range of rotation angle of shaft:
Within ±45 degrees from horizontal level
If any one or more of the specications above
are not met, the specied accuracy may not be
guaranteed, resulting in the YVP110 positioner
being damaged. An advance check is essential.
θ
(3) Attaching Feedback Lever
For a rotary-motion actuator, since it is often
difcult to secure sufcient working space
between the positioner and actuator, attach the
feedback lever before xing the YVP110 to the
actuator. Make sure that the stopper is located
on the side of the YVP110 as shown in Figure
3.9.
CAUTION
It is extremely likely that attaching the lever in the
wrong orientation will cause the feedback shaft
to rotate at an angle exceeding its mechanical
limits of ±55 degrees, resulting in the YVP110
being seriously damaged.
IMPORTANT
A stopper is attached to the feedback shaft to
prevent an over-rotation of the shaft as shown
below. When installing the lever, make sure that
you install it on the stopper.
Range of rotation angle of shaft: Within ±45 degrees
Mechanically allowable rotation angle: Within ±55 degrees

(2) Fixing Bracket to YVP110
Use the four M8 bolts that come with the
YVP110 to tightly x the mounting bracket to
the YVP110. (See “Part Names” on page 2.1)
The installation method is determined by the
combination of the control valve and positioner
as well as by the valve manufacturer who

(4) Fixing the YVP110 to Actuator with Bracket
Insert the pin attached to the valve spindle,
into the long hole of the feedback shaft of the
YVP110 positioner.
Before xing the bracket to the actuator,
carefully position it so that the center of the
rotation axis of the valve plug and that of
the YVP110 poistioner’s feedback shaft are
aligned both horizontally and vertically. After
the alignment has been checked, tightly x the
bracket to the actuator with the specied bolts.
Misalignment of these rotation axes decreases
the level of accuracy.

3.2.3 A/M Switching
To perform manual operation of the valve using
the A/M (automatic/manual) mode switching
mechanism of the YVP110, there needs to be a
pressure regulator for the air supply. To perform
manual operation, follow the procedure below.
(1) Turn the A/M selector switch clockwise to
change the switch position to M until it stops.
F0309.ai
WARNING
• Prior to changing the A/M selector switch
position, make sure that doing so will neither
cause an injury nor affect the process.
• Changing the A/M selector switch position
from M (manual) to A (automatic) or
A(automatic) to M(manual) during operation
will cause the valve stem to temporarily
move to a position different from the position
determined by the level of the input signal to
the positioner.
• If the pressure larger than the allowable
range of pressure gauge is applied, the
pressure gauge may possibly be damaged.
Supply pressure gauge
(optional)
(2) In manual mode, the pneumatic pressure
output to the valve actuator can be varied by
changing the regulator output pressure by more
than 70 kPa (approximately), regardless of
the input signal of the YVP110. For a YVP110
equipped with pressure gauges, you can read
the output pressure to the actuator.
When using the Double Acting Type, the
pneumatic pressure can only be varied from
OUT1 to the valve actuator. The pressure is
always 0% from OUT2 to the valve actuator.
Note that the valve position is not always in
accord with the regulator pressure.
(3) After you have nished manual operation,
turn the A/M selector switch counterclockwise
until the stopper pin touches the side of the
YVP110’s casing in order to ensure the switch
position changes to A.

• Be sure to cut off all inputs to the valve
actuator and other accessories of the valve
and actuator, including the air supply and
electric signal before making or modifying
the piping and wiring connections.
• The process must be shut down or the
control valve isolated from the process
by using bypass valves or the like when
making or modifying the piping and wiring
connections.
• Always cap the unused wiring ports with
blind plugs.
4.2 Piping
4.2.1 Air Supply
For stable operation of the YVP110 over a long
term, a clean and dry supply of air needs to be
maintained. Therefore, be careful about the
following:
(1) To prevent moisture, oil, and dust from being
led into the YVP110 through pipes, give careful
consideration to the choice of the air supply
system and supply air suction point as well
as installation of the air supply header and air
supply piping.
(2) The desired supply air must:
• Be dry air whose dew point is at least 10°C
lower than that of the ambient temperature.
• Be free from solid particles as a result of
being passed through a 5-µm or ner lter.
• Not contain oil at a concentration higher than
1 ppm in weight or volume.
• Not be contaminated by a corrosive,
explosive, ammable, or toxic gas.
• Comply with ANSI/ISA-57.3 1975 (R1981) or
ISA-S7.3-1975 (R1981).
(3) The YVP110 requires an air supply of 140 to
400 kPa. Within this range, regulate the air
supply pressure at a level within ±10% of the air
supply pressure specied for the actuator, and
at 10% of the actuator’s spring range or higher.
WARNING
Do not supply air at a pressure exceeding
the maximum rated air supply pressure of
the actuator or the YVP110 (400 kPa). Doing
so may result in a high risk of damage to the
equipment or lead to an accident.
Supplying air to the valve actuator may cause
the valve stem to move. Exercise extreme
caution with regard to safety.
4.2.2 Pneumatic Piping
Connect the air supply pipe to the SUP port of the
YVP110, and the output pressure pipe to the OUT1
port. When using the Double Acting Type, connect
the output pressure pipe to the OUT2 port of the
YVP110. A power failure will result in the fail-safe
action; OUT1=0% and OUT2=100%. Use O.D.
6-mm/I.D. 4-mm or O.D. 8-mm/I.D. 6-mm copper
tubes for piping, and pneumatic pipe ttings for
joints. After nishing the piping, check that there is
no leakage from the joints.
Note that a YVP110 has two air supply ports (SUP):
one at the rear and the other on the side. When
delivered, the rear SUP port is capped with a blind
plug. Thus, to use the rear SUP port, remove the
blind plug and cap the side SUP port with it. At this
time, be very careful that no foreign matter or dust
caught in the sealing tape is allowed to enter inside
the pipe.
Figure 4.1 shows the pneumatic piping ports. The
port specication can be chosen when ordering the
YVP110.

CAUTION
• To obtain the maximum air processing ow
rate of the YVP110, the inner diameter of
the piping tube needs to be at least 6 mm.
When the YVP110 is combined with a highcapacity actuator and a minimum response
speed is required, use a tube whose inner
diameter is 6 mm or larger.
• Do not use an unnecessarily long tube or
piping as it will decrease the air ow rate,
thus leading to a decrease in response
speed.
• Perform sufcient ushing of the piping
tubes and ttings before use to ensure that
no foreign matter such as metal refuse may
enter the piping.
• When performing the piping connection, be
sufciently careful that a piece of sealing
tape or other solid or uid sealing material
does not enter the piping.
• When using the Double Acting Type and
piping to the OUT2 port, ensure that the plug
for the OUT2 Pressure Gauge does not get
turned around.
• When using the Double Acting Type, adjust
the pressure balance of the control relay as
required (in reference to Section 6.3.4).

absolutely must read “Installation and Operating
Precautions for JIS Flameproof Equipment” at
the end of this manual prior to the work.
4.3.1 Recommended Cables
For wiring for a YVP110, use a cable for H1 eldbus
segments specied by the Fieldbus FOUNDATIONTM.
A shielded cable is recommended. For the details
of cables required for H1 eldbus segments, see
"Fieldbus Technical Information"(TI 38K3A01-01).
Choose cables suitable for the respective ambient
temperature ranges, especially when they are to be
laid in a hot or cold place.
When laying cables in or through a place where
the atmosphere may include a toxic gas or liquid,
or oil or solvent, choose wires and cables made of
materials that have sufcient durability.
4.3.2 Precautions on Wiring
IMPORTANT
• Prevent the cables from being affected
by noise induced from a high-capacity
transformer or power supply to a motor.
• As shown in Figure 4.2, remove the terminal
box cover and dust proong plug when
performing a wiring connection. Be sure to
securely seal the unused wiring port with a
blind plug.
• To make the cables watertight and to
prevent them from being damaged, it is
recommended to use a cable conduit and
duct. Also for the same reasons, be sure to
use a watertight adapter for the connection
of the conduit to the port.

<5. Setup>
5. Setup
5.2 Setting Basic Parameters
CAUTION
During the setup especially when autotuning
is being executed, the valve stem may happen
to move suddenly to an unexpected direction.
Before starting the setup, check and conrm that
the process has been shut down or the control
valve is isolated from the process. During the
setup, keep away from the movable parts to
avoid injury.
5.1 General
After mechanically attaching the YVP110 to an
actuator and nishing the wiring and piping, connect
the YVP110 to a eldbus and make settings, such
as carrying out auto tuning and setting the tight-shut
option, using a parameter setting tool or the like.
First, set the target mode's in the parameters
MODE_BLK of the transducer block and AO
function block to O/S (Out of Service). When either
one or both of the transducer block and AO function
block are in the O/S mode, the transducer block's
parameters that determine the valve actions are
write-locked.
(1) Selecting the Acting Direction of Valve
In the parameter ACT_FAIL_ACTION, set
the value, 1 or 2, corresponding to the acting
direction of the valve, whether the valve opens
or closes due to an increase of the pneumatic
pressure. The setting in ACT_FAIL_ACTION
determines the relationship between the
pneumatic input signal and 0-100% of the
valve position, where the 0% position means
complete closure.
5-1
IMPORTANT
For the operation of a parameter setting tool,
read the manual of each tool. Also, read the
Chapters 8 through 10 and 12 of this manual
to become familiar with the conguration of
the eldbus instrument and the function of the
transducer block before starting adjustment.
Check that the piping and wiring connections are
all correct, and then supply the specied input
voltage and air pressure. For the connection to
the eldbus, see the chapters 4.3 'Wiring' and 8.4
'System Conguration'.
Parameter settings for the actuator and valve are to
be made in the parameters in the transducer block
inside the YVP110 positioner. For details of each
parameter, refer to the parameters list in Appendix
1. Follow the procedure below.
Set basic parameters (Section 5.2)
Carry out tuning (Section 5.3)
Check valve actions (Section 5.4)
1 = air to open
2 = air to close
IMPORTANT
For the transducer block, the 0% output always
me ans complet e cl osure of the valve. Set
ACT_FAIL_ACTION correctly in accordance
with the acting direction of th e valve used.
Nonetheless, the 0-100% of the transducer
block's output can be logically reversed by setting
IO_OPTS in the AO block to true.
Independently of the above setting, YVP110
always acts identical upon power off and cut-off
of the air supply.
When a power failure or serious hardware
damage is detected, the YVP110 cuts the
current signal being fed to the I/P module to
zero, moving the valve to the safe side. The
action of the YVP110 upon occurrence of a
communication error can be predened by AO
block’s parameters; see Section 13.3.1, “Fault
State.”
Set transducer block's parameters (Section 5.5)
Figure 5.1 Setup Procedure
F0501.ai
IM 21B04C01-01E
<5. Setup>
(2) Selecting the Actuator Type
For the parameter VALVE_TYPE, set the value,
1 or 2, in accordance with the actuator type.
Choosing the linear-motion type automatically
corrects a linearity error that is inherently
caused between the linearly acting actuator
and the rotating displacement sensor inside the
YVP110 actuator.
5.3 Carrying out Tuning
For the rst time after installing the YVP110
on the actuator or anytime after detaching the
YVP110 and installing it again on the actuator,
be sure to perform step (1) below, or (2) and
(3) to carry out all adjustments. Otherwise, the
adjustments cannot be carried out correctly.
From the next and any time thereafter, perform
only step (2) or (3) independently.
After detaching the YVP110 from the valve
actuator and then reinstalling it to the actuator,
be sure to perform step (2) below.
CAUTION
5-2
CAUTION
This function strokes the valve over its full range.
Do not execute while valve is controlling the
process. Keep away from the movable parts to
avoid injury.
After selecting the acting direction of the valve and
the actuator type, carry out auto tuning (and manual
tuning, if necessary). The auto tuning program
automatically:
• Adjusts the zero-point and span.
• Adjusts the parameter settings for controlling
the valve.
IMPORTANT
Auto Tuning in YVP110 sets the 0% point at the
position where the valve is fully closed and 100%
point at the position where the valve stem stops
against the mechanical stopper(fully open). If it is
necessary to adjust the zero point and span
precisely to the rated stroke of the valve, carry
out travel calibration which is described later in
this chapter after the Auto Tuning.
To carry out auto tuning, write a value to the
parameter AUTO_TUNE_EXEC according to the
following procedure.
(1) To sequentially adjust the zero-point and span,
and then control parameter settings for the
rst time after installing the YVP110 on a valve
actuator, write:
4 (= travel calibration at stop point and
control parameter tuning).
(2) To leave the control parameter settings
unchanged and only perform zero-point and
span adjustments such as after detaching the
YVP110 from the valve actuator and restoring it,
write:
2 (= travel calibration at stop point).
(3) To leave zero-point and span settings
unchanged and only adjust control parameter
settings, such as after the hysteresis of the
valve actions has greatly changed, write:
3 (= control parameter tuning).
The time needed to complete the adjustments,
which varies with the actuator size and the
hysteresis of the actions, is roughly 4 minutes
for a mid-capacity (capacity of around 3 liters)
actuator.
If you want to abort auto tuning for some reason
such as when you have started it while leaving
the air supply shut off, write:
5 (= cancel execution).
IM 21B04C01-01E
<5. Setup>
5-3
The tuning result will be written to AUTO_
TUNE_RESULT. The value of AUTO_TUNE_
RESULT is 255 and is displayed as “In
operation” while auto tuning is running, and will
change to 1 which is displayed as “Succeeded”
when auto tuning has nished successfully. In
the event of a warning or error, a value other
than those below will be displayed. For details,
see the specications for the transducer block.
1 = succeeded
2 = canceled
255 = in operation
The values of the hysteresis of valve actions
and the air supply pressure measured during
auto tuning are stored in parameters of the
transducer block inside the YVP110. Note that
pressure data such as air supply pressure data
are available only for a YVP110 with an optional
pressure sensor.
CAUTION
Ensure that the pressure of the air supply to
the YVP110 positioner is regulated within the
specied range. If it differs from the pressure
during actual operation, or if it is unstable,
optimum tuning results may not be obtained.
The following parameters are tuned by carrying out
auto tuning: (For details, see secction A6.4)
SERVO_GAIN

X_BST_OFF_THRESHOLD *
(the addition value to threshold for switching
off boost action for exhaust)
X_BOOST_VALUE *
(the addition boost value for exhaust)
*Applicable only for Double Acting Type
Normally, control parameters need not be
readjusted after auto tuning. (Should there be a
problem, see Chapter 16, “Troubleshooting.”)
If you want to carry out ne adjustments of the
zero-point and span settings, perform the travel
calibration as follows.
l Travel Calibration
If the full stroke of the valve is too large for the
maximum required ow rate, you can change
the span of the travel by carrying out a travel
calibration.
(1) First, vary the value of FINAL_VALUE.value
(see caution) to move the stem and adjust the
stem to the desired point that you want to set as
the 100% position.
(2) Next, write 3 to TRAVEL_CALIB_EXEC. This
changes the span while leaving the zero point
unchanged.
TRAVEL_CALIB_EXEC:
1 = off
2 = 0%-point calibration (no change to span)
3 = span calibration (no change to 0% point)
4 = 50%- point calibration
(no change to either span or 0% point)
CAUTION
Only when the target mode's in both the AO and
transducer blocks are O/S, can FINAL_VALUE.
value be written.
The result of the travel calibration will be written to
TRAVEL_CALIB_RESULT.

5.4 Checking Valve Actions
After carrying out auto tuning, check step
responses by changing the value of the transducer
block's nal valve position setpoint, FINAL_VALUE.
value. Also, check whether the valve acts correctly
over the 0-100% position range.
NOTE
Only when the target mode is in MODE_BLK
parameters in both the AO and transducer blocks
are O/S, can FINAL_VALUE.value be written.
It is not usually necessary to readjust the control
parameters after auto tuning. However, when
using the Double Acting Type or if the expected
response characteristics cannot be obtained
using auto tuning, either conduct manual tuning
in reference to APPENDIX 6 or refer to Section
18.5 Troubleshooting Auto Tuning.

Transducer Block
Set the following parameters as necessary. For the
settings made as default when shipped, see the
parameter lists in Appendix 1.
(1) Position-to-ow Rate Characteristic Type
The parameter POSITION_CHAR_TYPE
denes the characteristics between the valve
position and ow rate, and is set to linear by
default. Write the appropriate value:
1 = linear
2 = equal percent (50:1)
3 = equal percent (30:1)
4 = quick open (reversal of equal % - 50:1)
5 = Camex Percentage
255 = user-dened
Writing the value 255 allows you to dene the
desired characteristics by 10 line segments for
evenly divided input levels. The coordinates
(0,0) and (100,100) are xed; set the values
corresponding to OUT(Output of AO block) =
10%, 20%, 30%..., 80%, 90%. Note that a set
value must be greater than the preceding set
value; the output must increase as the input
increases.
Even if the range of FINAL_VALUE.value is
limited by FINAL_VALUE_RANGE, the actual
valve position is set to outside the FINAL_
VALUE_RANGE setting when the tight-shut or
full-open action described below is activated.
(3) Tight-shut and Full-open Actions
The tight-shut action is an action to decrease
the output pressure to a level much lower than
the 0% pressure level (or to increase it much
higher than the 0% pressure level for an airto-close valve) when FINAL_VALUE.value
is less than FINAL_VALUE_CUTOFF_LO in
order to ensure that the valve is tightly shut
off. Conversely, the full-open action is an
action to increase the output pressure to a level
much higher than the 100% pressure level (or
decrease it much lower than the 100% pressure
level for an air-to-close valve) when FINAL_
VALUE.value is larger than FINAL_VALUE_
CUTOFF_HI in order to ensure that the valve is
fully open.
A hysteresis of 1% is applied to the thresholds,
FINAL_VALUE_CUTOFF_LO and FINAL_
VALUE_CUTOFF_HI.
IM 21B04C01-01E
<5. Setup>
(4) Thresholds for Limit Switches
Just like hardware limit switches for a valve,
on/off status signals can be generated when
the valve position read-back signal FINAL_
POSITION_VALUE.value reaches specied
levels. These on/off statuses can be transferred
to a DI function block.
Write the threshold for the upper limit switch to
LIMSW_HI_LIM, and the threshold for the lower
limit switch to LIMSW_LO_LIM.
A hysteresis of 1% is applied to the thresholds,
LIMSW_HI_LIM and LIMSW_LO_LIM.
CAUTION
To make a DI block read the on/off statuses of a
limit switch, set CHANNEL of the DI block to:
• 2, for reading the on/off status of the upper
limit switch.
• 3, for reading the on/off status of the lower
limit switch.
5-5
(5) Thresholds for Operation Result Integration
Alarms
The YVP110 has a function to integrate the
following operation result quantities individually:
• TOTAL_CYCLE_COUNT (incremented by 1
at each change in the direction of the action)
• TOTAL_TRAVEL (in % where full stroke =
100%)
• TOTAL_OPEN_TIME (in hours)
• TOTAL_CLOSE_TIME (in hours)
• TOTAL_NEAR_CLOSE_TIM (total at nearly
closed time in hours)
• SERVO_WARN_COUNT (Total number of
times of Servo output drift warning)
When these values exceed the respective
thresholds below, corresponding alarms are
output. Set the thresholds as necessary.
• CYCLE_COUNT_LIM
• TRAVEL_LIM
• OPEN_TIME_LIM
• CLOSE_TIME_LIM
• NEAR_CLOSE_TIME_LIM
Also, set NEAR_CLOSE_THRESHOLD,
which denes the threshold of the valve
position for counting NEAR_CLOSE_TIME,
as necessary.
For other alarms and self-diagnostic
functions, see “12.6 Online Diagnostics”.

6.1 General
The modular structure of the YVP110 increases the
ease of maintenance work. This chapter describes
cleaning and part replacement procedures that
should be done for maintenance of the YVP110.
The YVP110 is a precision instrument; read the
following carefully when carrying out maintenance.
For calibrations, see Chapter 5.
CAUTION
Precautions for ATEX ameproof type and
type nA instruments
• Flameproof type and type nA instrumets
must be, as a rule, removed to a nonhazardous area for maintenance and be
disassembled and reassembled to the
original state.
• On the ameproof type and type nA
instruments the terminal cover is locked by
an Allen head bolt (shrouding bolt). When
a shrouding bolt is driven clockwise by an
Allen wrench, it is going in and cover lock is
released, and then the cover can be opened.
When a cover is closed it should be locked
by a shrouding bolt without fail. Tighten the
shrouding bolt to a torque of 0.7 N·m.
6.2 Periodic Inspections
To maintain problem-free plant operation, periodic
inspections are essential. At each periodic
inspection, be especially careful when ensuring
that:
• No external damage can be seen.
• No leakage from the YVP110 or the piping
around it can be detected.
• No build up in the drain, or dust or oil adhering
to the air supply line has occurred.
6.2.1 Cleaning the Fixed Nozzle
The xed nozzle of the YVP110 is attached to the
control relay’s surface that engages the YVP110’s
main structure (see Figure 6.2). Detach the
control relay from the main structure of YVP110 by
following the instruction shown in 6.3.1. Thread a
wire with a 0.25-mm diameter through the nozzle to
clean it. After cleaning the nozzle, place the nozzle
and O-ring at the original position and attach the
control relay again.

times, or after the control relay has been in use
for 6 years.

6.3.4 Tuning the Pressure Balance of
Control Relay
When you use a double-acting cylinder actuator,
adjust the pressure balance of the control relay, if
necessary.
The optimal point of pressure balance slightly differs
depending on the packing and load characteristics
of the cylinders used, but in general, approx. 50
to 90% of the supply air pressure is said to be
appropriate.
The pressure balance of the YVP110 is set to
approx. 75% at the time of shipment.
It is possible to reduce the hunting phenomenon
and air consumption by adjusting the balance
pressure.

However, if the pneumatic piping is connected to
the valve actuator, the pressure of a cylinder on one
side becomes higher, and the balance cannot be
maintained.
If you want to increase the balance pressure,
turn the screw for adjusting the balance pressure
(shown in Figure 6.6) counterclockwise. If you want
to decrease the balance pressure, turn the screw
clockwise. At this time, you do must not to loosen
the screw beside the adjustment screw.

8-1
8.1 Outline
Fieldbus is a bi-directional digital communication
protocol for eld devices, which offers an
advancement in implementation technologies for
process control systems and is widely employed by
numerous eld devices.
YVP110 employs the specication standardized
by The Fieldbus Foundation, and provides
interoperability between Yokogawa devices and
those produced by other manufacturers. Fieldbus
comes with software consisting of AO function
block, two DI function blocks OS function block, IS
function block, AR function block and optional PID
function block, providing the means to implement a
exible instrumentation system.
For information on other features, engineering,
design, construction work, startup and maintenance
of Fieldbus, refer to “Fieldbus Technical Information”
(TI 38K3A01-01E).
8.2 Internal Structure of YVP110
The YVP110 contains two virtual eld devices
(VFD) that share the following functions.
8.2.1 System/network Management VFD
• Sets node addresses and Physical Device tags
(PD Tag) necessary for communication.
• Controls the execution of function blocks.
• Manages operation parameters and
communication resources (Virtual
Communication Relationship: VCR).
8.2.2 Function Block VFD
(1) Resource block
Manages the information common to each FB
VFD in YVP110.
(2) Transducer block
Located between Hardware I/O(actuator,
sensor) and AO/DI function blocks, pass the
control signal from AO function block to I/P
module to control the valve position.
(3) AO function block
• Accepts a control signal from an upstream
block and pass the signal to Transducer
block.
• Accept a valve position signal from
Transducer block and feedback it to an
upstream block.
(4) DI function block
Receives the discrete signal from Transcducer
blcok and output them.
(5) PID function block(optional)
Offers PID control function.

8.4 System Conguration
The following instruments are required for use with
Fieldbus devices:
IM 21B04C01-01E
<8. About Fieldbus>
8-2
• Power supply:
Fieldbus requires a dedicated power supply. It
is recommended that current capacity be well
over the total value of the maximum current
consumed by all devices (including the host).
Conventional DC current cannot be used as is.
• Terminator:
Fieldbus requires two terminators. Refer to
the supplier for details of terminators that are
attached to the host.
• Field devices:
Connect the eld devices necessary for
instrumentation. YVP110 has passed the
interoperability test conducted by The Fieldbus
Foundation. In order to properly start Fieldbus,
it is recommended that the devices used satisfy
the requirements of the above test.
• Host:
Used for accessing eld devices. A
dedicated host (such as DCS) is used for
an instrumentation line while dedicated
communication tools are used for experimental
purposes.
• Cable:
Used for connecting devices. Refer to “Fieldbus
Technical Information” (TI 38K3A01-01E) for
details of instrumentation cabling. Provide a
cable sufciently long to connect all devices.
For eld branch cabling, use terminal boards
or a connection box as required. If the total
length of the cable is in a range of 2 to 3 meters
for laboratory or other experimental use, the
following simplied cable (a twisted pair wire
with a cross section of 0.9 mm2 or more (AWG
#18) and cycle period of within 5 cm (2 inches)
may be used. Termination processing depends
on the type of device being deployed. For
YVP110, use an M4 screw terminal claw. Some
hosts require a connector.
Refer to Yokogawa when making arrangements to
purchase the recommended equipment.
The number of devices that can be connected to
a single bus and the cable length vary depending
on system design. When constructing systems,
both the basic and overall design must be carefully
considered to allow device performance to be fully
exhibited.
8.4.1 Connection of Devices
Connect the devices as shown in Figure 9.1.
Connect the terminators at both ends of the
trunk, with a minimum length of the spur laid for
connection.
The polarity of signal and power must be
maintained.

F0802.ai
Before using a Fieldbus conguration tool other
than the existing host, conrm it does not affect the
loop functionality in which all devices are already
installed in operation. Disconnect the relevant
control loop from the bus if necessary.
8.5 Integration of DD
If the host supports DD (Device Description), the
DD of the YVP110 needs to be installed. Check if
host has the following directory under its default DD
directory.
594543/0001
594543/0007 (/EE)
(594543 is the manufacturer number of
Yokogawa Electric Corporation, and 0001
or 0007 is the YVP110 device number,
respectively.)
If this directory is not found, DD of YVP110 has not
been included. Create the above directory and copy
the DD le (0m0n.ffo,0m0n.sym) (m, n is a numeral)
into the directory.
Once the DD is installed in the directory, the name
and attribute of all parameters of the YVP110 are
displayed.
Off-line conguration is allowed by using the
capability le (CFF). If you do not have the DD or
capability le for the YVP110, you can download it
from www.yokogawa.com/d/
IMPORTANT
For ofine conguration, use the CFF which
matches the specication of the instrument to be
congured. For YVP110, there are three types
of CFF le; one for standard type instruments,
second for the instruments with one or two PID
function blocks are available and the other can
be selected between former two types using
capability level description. Using unmatched
CFF will cause an error upon downloads, etc.

This chapter contains information on how to adapt
the function and performance of the YVP110 to suit
specic applications. Because two or more devices
are connected to Fieldbus, settings including the
requirements of all devices need to be determined.
Practically, the following steps must be taken.
(1) Network design
Determines the devices to be connected to
Fieldbus and checks the capacity of the power
supply.
(2) Network denition
Determines the tag and node addresses for all
devices.
(3) Denition of combining function blocks
Determines the method for combination
between each function block.
(4) Setting tags and addresses
Sets the PD Tag and node addresses one by
one for each device.
IMPORTANT
Do not turn off the power immediately after
setting. If the power is turned off within 40
seconds after setting is made, the modied
parameters are not saved and the settings return
to the original values.
9.1 Network Design
Select the devices to be connected to the Fieldbus
network. (Refer to 8.4 'System Conguration' for
selection of the devices.)
First, check the capacity of the power supply. The
power supply capacity must be greater than the
sum of the maximum current consumed by all
devices to be connected to Fieldbus. The maximum
current consumed (power supply voltage 9 V to 32
V) for YVP110 is 17 mA. The cable must have the
spur in a minimum length with terminators installed
at both ends of the trunk.
(5) Communication setting
Sets the link between communication
parameters and function blocks.
(6) Block setting
Sets the parameters for function blocks.
The following section describes each step of the
procedure in the order given. Using a dedicated
conguration tool allows the procedure to be
signicantly simplied. This section describes the
procedure to be assigned for a host which has
relatively simple functions. For operation of the
host, refer to the instruction manual for each host.
No details of the host are explained in the rest of
this material.
IMPORTANT
Connecting a Fieldbus conguration tool
to a loop with its existing host may cause
communication data scrambles resulting in a
functional disorder or a system failure.
9.2 Network Denition
Before connection of devices with Fieldbus, dene
the Fieldbus network. Allocate PD Tag and node
addresses to all devices (excluding such passive
devices as terminators).
The PD Tag is the same as the conventional
one used for the device. Up to 32 alphanumeric
characters may be used for denition. Use a
hyphen as a delimiter as required.
The node address is used to specify devices for
communication purposes. Because data is too
long for a PD Tag, the host uses the node address
in place of the PD Tag for communication. A range
of 20 to 247 (or hexadecimal 0x14 to 0xF7) can
be set. Generally, the device (LM device) with bus
control function (Link Master function) is allocated
from a smaller address number (20) side, and other
devices (BASIC device) without bus control function
allocated from a larger address number (247) side
respectively.

periodically checked to identify when a new device
is mounted. Care must be taken not to allow the
address range to become wider, which can lead to
exhaustive consumption of Fieldbus communication
performance.

To ensure stable operation of Fieldbus, determine
the operation parameters and set them to the LM
devices. While the parameters in Table 9.2 are to
be set, the worst-case value of all the devices to
be connected to the same Fieldbus must be used.
Refer to the specication of each device for details.

9.3 Denition of Combining
Function Blocks
The input/output parameters for function blocks
are combined. Practically, setting is written to the
YVP110 link object with reference to “Block setting”
in Section 9.6 for details.
For the YVP110, in order to minimize the delay in
data transfer between Transducer block and AO
function block, transducer block are designed to
be executed in conjunction with the execution of
AO function block. Therefore, in order to activate
Transducer block, it is necessary that AO function
block is always dened in the schedule.
The combined blocks need to be executed
synchronously with other blocks on the
communications schedule. In this case, change the
YVP110 schedule according to the following table.
Enclosed values in the table are factory-settings.
YVP110 schedule is set as shown in the following.
Change it as necessary.

9.4 Setting of Tags and
Addresses
This section describes the steps in the procedure
to set PD Tags and node addresses in the YVP110.
Connect YVP110 with other network devices and
turn on the power of the host and the bus.
There are three states of Fieldbus devices as
shown in Figure 9.4, and if the state is other than
the lowest SM_OPERATIONAL state, no function
block is executed. YVP110 must be transferred to
this state when a tag or address is changed.

YVP110 has a PD Tag (CV1001) and node
address (247, or hexadecimal 0xF7) that are set
upon shipment from the factory unless otherwise
specied. If two YVP110s are connected at a time,
one YVP110 will keep the address upon shipment
while the other will have a default address(See
Figure 9.2). To change only the node address,
clear the address once and then set a new node
address. To set the PD Tag, rst clear the node
address and clear the PD Tag, then set the PD Tag
and node address again.
Devices whose node address was cleared will
await the default address (randomly chosen from
a range of 248 to 251, or from hexadecimal 0xF8
to 0xFB). At the same time, it is necessary to
specify the device ID in order to correctly specify
the device. The device ID of the YVP110 is
5945430001xxxxxxxx or 5945430007xxxxxxxx.
(The xxxxxxxx at the end of the above device ID is a
total of 8 alphanumeric characters.)
9.5 Communication Setting
To set the communication function, it is necessary
to change the database residing in SM-VFD.
Subscriber (BNU) VCR
A Subscriber receives the data from another
function block(s). This type of communication
is called BNU (Buffered Network-triggered
Unidirectional) VCR.
A Server VCR is capable to respond to requests
from a Client (QUB) VCR after the Client initiates
connection to the Server successfully. A Source
VCR transmits data without established connection.
A Sink (QUU) VCR on another device can receive
it if the Sink is congured so. A Publisher VCR
transmits data when LAS requests so. An explicit
connection is established from Subscriber (BNU)
VCR(s) so that a Subscriber knows the format of
published data.
Parameters must be changed together for each
VCR because modication for each parameter may
cause inconsistent operation.
9.5.2 Function Block Execution Control
According to the instructions given in Section 9.3,
set the execution cycle of the function blocks and
schedule of execution.
9.5.1 VCR Setting
Set VCR (Virtual Communication Relationship),
which species the called party for communication
and resources. YVP110 has 29 or 33 VCRs (with
/EE) whose application can be changed, except for
the rst VCR, which is used for management.
YVP110 has VCRs of four types:
Server(QUB) VCR
A Server responds to requests from a host. This
communication needs data exchange. This
type of communication is called QUB (Queued
User-triggered Bidirectional) VCR.
Source (QUU) VCR
A Source multicasts alarms or trends to other
devices. This type of communication is called
QUU (Queued User-triggered Unidirectional)
VCR.
Publisher (BNU) VCR
A Publisher multicasts AI block output to
another function block(s). This type of
communication is called BNU (Buffered
Network-triggered Unidirectional) VCR.

9.6.1 Link Object
Link object combines the data voluntarily sent
by the function block with VCR. YVP110 has 25
or 50 (with /EE) link objects. A single link object
species one combination. Each link object has the
parameters listed in Table 9.5. Parameters must
be changed together for each VCR because the

10.1 Block Modes
All function blocks have modes. All blocks have
their mode, expressed by MODE_BLK parameter.
It is a structure of four components; Target,
Actual, Permitted and Normal. Target is the mode
into which an operator wants to bring this block.
This component is writable. Actual shows the
actual mode of the block and is read-only. When
necessary condition is satised, actual mode
becomes same to target. There is a chance that
actual mode says different from target by some
reason. Permitted mode shows which mode is
allowed in this Function Block. Normal mode is a
memo for operator to record mode that an operator
expects in normal conditions.
The table below shows the modes supported by
each function block contained in a YVP110.
Modes marked with ( ) in the above table cannot be
specied as “target”.
LO mode
Means Local Override mode. If the PID block
enters LO mode, the block output follows the
tracking value (TRK_VAL). In AO block, the block
enters LO mode when the block detects the fault
status. In this case, the block holds the output or
outputs the pre-congured value (FSTATE_VALUE)
according to the setting of options.
Man mode
Means Manual mode. If the data status of a
function block’s input is bad or its target mode is
Man, the block enters Man mode. In Man mode,
the function block does not update its OUT value.
If the target is also Man, it allows the user to write a
desired value to it.
Auto mode
In Auto mode, the function block performs the
specied calculations based on the setpoint
and outputs the result, independently without
interlocking with another function block. The user
can write the setpoint of a function block in this
mode if the target is Auto. If the target mode of
a function block is Auto, or if both of the following
conditions are met for a function bock, the block
enters Auto mode:
• The target mode is Cas or RCas.
• There is an error in communication with the
upstream function block.
Cas mode
The following are outlines of each mode.
O/S mode
Means Out of Service mode, in which the block
does not run, and its output and setpoint maintain
their previous values.
IMan mode
Means Initialization Manual mode. Only the AO and
PID blocks in the YVP110 support this mode. When
one of these blocks detects a loss of a correct
path to the downstream block (such as when the
downstream block is in the O/S, Man, Auto or LO
mode), it enters IMan mode. For example, when
the data status of BKCAL_IN in a PID block is “bad”
or “good: not invited”, the PID block enters IMan
mode.
Means Cascade mode. In Cas mode, the function
block performs the specied calculations based on
the setpoint that is input from a different function
block via the cascade input parameter and outputs
the result.
ROut mode
Means Remote Output mode. In ROut mode, the
output of the function block is set to the value of the
remote output parameter that is written by a host
computer or others. To prevent a sudden change in
output, the block’s calculations are initialized when
a change in mode occurs.
IM 21B04C01-01E
<10. Actions of YVP110 During Operation>
10-2
RCas mode
Means Remote Cascade mode. In RCas
mode, the function block performs the specied
calculations based on the setpoint that is input from
host computer or others via the remote cascade
parameter, and outputs the result.

10.2 Alarm Generation
When the YVP110 detects an abnormality in the
device itself by the self-diagnostic function, a device
alarm is issued from the resource or transducer
block. An abnormality in a function block or in a
process value is issued from the corresponding
block as a block error or process alarm.
A YVP110 can report the following alarms and
events.
Analog alerts: A type of alarm generated when
a process value or a deviation value exceeds a
specied limit in the following blocks:
PID block : HI, HI_HI, LO, LO_LO, DV_HI, DV_LO
Discrete alerts: A type of alarm generated when
an abnormal status is detected. For the resource
block, a discrete alert is generated as a block alarm
or write-error alarm. For the DI block, a discrete
alert is generated as a block alarm or DISC alarm.
For the Transducer block, AO, OS, IS, AR block and
PID block, a discrete alert is only generated as a
block alarm.
Update alerts: Generated whenever a change is
made to the settings of the certain parameters.
Table 10.2 shows examples of block mode
combinations in a YVP110 (however, it does not
show all patterns). When a block changes mode
or the data status of a signal changes for some
reason, the other blocks connected to that block
identify the change by detecting the change in
status of an input signal, and change their modes,
too. For example, when the data status of BKCAL_
IN in a PID block changes to bad, the PID block
automatically change mode to IMan to initialize the
control of its downstream block.
The respective modes to which each block should
enter upon occurrence of a communication error
and at a restart, and the handling of signals in
each mode may be dened in the block’s option
parameters such as IO_OPTS and STATUS_
OPTS. For details, see the detailed descriptions of
each function block.
Table 10.3 shows the elements composing an alert
object.

10.3 Simulation Function
The YVP110 has a function to simulate input
signals to its internal function blocks and makes the
blocks to carry out the specied actions with the
simulated input signals in order to allow for testing
applications in the host computer or alarm handling
processes. Each function block has a parameter
to switch on/off the simulation function. To prevent
this parameter setting from being modied during
plant operation by mistake, a hardware switch
labeled SIM.ENABLE is provided on the YVP110’s
amplier assembly. Sliding this switch position
to ON enables the simulation function to run.
Remotely writing “REMOTE LOOP TEST SWITCH”
to SIM_ENABLE_MSG also causes the same
effect as turning ON the SIM.ENABLE switch;
however, the value of SIM_ENABLE_MSG will
be lost when the power to the YVP110 is turned
off. In short, simulation can be carried out if the
hardware SIM.ENABLE switch is ON or if the value
of SIM_ENABLE_MSG is “REMOTE LOOP TEST
SWITCH”.
When the simulation can be carried out, alarms
generated from the resource blocks mask the other
device alarms. Hence, simulation must be disabled
immediately after it has nished.

11.1 General
The resource block stores device hardware
information related to all function blocks in the same
device, such as the memory size, and controls
the device hardware and internal function blocks.
Regardless of the execution schedule of the
function blocks, the resource block runs at a certain
interval.
11.2 Alarm Processing
The resource block generates a block alarm in the
following cases:
• An error represented by a bit in BLOCK_
ERROR, shown in the table below, has
occurred (identied as a Block alarm).
• A static parameter has been written (identied
as an update event).
• The value of a write-locked parameter has been

12-1
12.1 General
The transducer block works as an interface
between the hardware I/O (actuator, sensor) and
internal function blocks. Most functions of the
YVP110 as a valve positioner are packed in the
transducer block. Major functions of the transducer
blocks include:
• Transmission and reception of setpoint and
readback signals for valve position
• Pressure and temperature measurement
(pressure measurement requires the optional
sensor)
• Fail safe
The transducer block in a YVP110 is connected
to an AO function block and two DI blocks via its
channels as shown below.
12.2 Forward Path
The following describes the signal input from the
AO block to the transducer block and then passed
to the device hardware side.
12.2.1 Input from AO Block
The OUT value of the AO block is input to the
transducer block. This input action is halted when:
• The channel number of the AO block is not set
as 1; or
• The AO block is in O/S mode.
Based on the input value from the AO block,
transducer block:
• Performs the ow rate-to-valve position
conversion;
• Limits the setpoint within a specied range; and
• Performs tight-shut or full-open action as
necessary.
The input from the AO block is always a percentage
value where the transducer block always
regards 0% to be the shut-off position. Make
the correct settings at initial setup according to
the specications of the valve (in reference with
Chapter 5, “Setup”).

The parameter POSITION_CHAR_TYPE denes
the characteristics between the valve position and

3 = equal percent (30:1)
4 = quick open (reversal of equal percent 50:1)

corresponding to OUT(Output of AO block) = 10%,
20%, 30%..., 80%, 90%. Note that a set value must
be greater than the preceding set value; the output
must increase as the input increases.
This ow rate conversion is applied to the signal in
the backword path as well.
12.2.3 FINAL_VALUE and Range
The parameter FINAL_VALUE contains the valve
position setpoint for valve control, and its value is
always a percent value where 0% is the shut-off
position as is the case for the input signal. High and
low limits for the value of FINAL_VALUE.value can
be set in FINAL_VALUE_RANGE.
12.2.4 Tight-shut and Full-open Actions
The tight-shut action is an action to decrease the
output pressure to a level much lower than the 0%
pressure level for an air-to-open valve (or increase
it to a level much higher than the 0% pressure level
for an air-to-close valve) when FINAL_VALUE.value
is less than FINAL_VALUE_CUTOFF_LO in order
to ensure that the valve is tightly shut off. After the
tight-shut action is activated, when FINAL_VALUE.
value becomes greater than FINAL_VALUE_
CUTOFF_LO by 1% or more, the tight-shut action
will turn off.
Conversely, the full-open action is an action to
increase the output pressure to a level much higher
than the 100% pressure level for an air-to-open
valve (or decrease it to a level much lower than the
100% pressure level for an air-to-close valve) when
FINAL_VALUE.value is larger than FINAL_VALUE_
CUTOFF_HI in order to ensure that the valve is fully
open. After the full-open action is activated, when
FINAL_VALUE.value becomes less than FINAL_
VALUE_CUTOFF_HI by 1% or more, the full-open
action will turn off.
Although the actual output signal level is changed
to a level outside the range during the period when
the tight-shut or full-open action is on, the value of
FINAL_VALUE.value remains as computed and is
not affected by these actions.
12.3 Backward Path
The following describes the signal input from the
device hardware to the transducer block and then
passed to other function blocks.
12.3.1 FINAL_POSITION_VALUE
The parameter FINAL_POSITION_VALUE contains
a percentage value of the valve position sent from
the position sensor where 0% is the shut-off position
as is the case for FINAL_VALUE.value. When one
or more of the following conditions become true, the
data status of FINAL_POSITION_VALUE becomes
Bad, which is notied to the connected AO block
and upstream function blocks:
• Bad - Out of service: The block is in the O/S
mode.
• Bad - Sensor failure: The position sensor has
failed.
• Bad - Device failure: The A/D converter has
failed.
• Bad - Non specic: The deviation exceeds the
limit.
12.3.2 Limit Switches
Limit switches monitor whether the valve position
has reached a specied high or low limit position
and send the high limit switch status to channel 2
and the low limit switch status to channel 3. The
thresholds (settings) for the high and low limit
switches should be set in LIMSW_HI_LIM and
LIMSW_LO_LIM. The switch statuses sent to
channels 2 and 3 mean:
0 = off (inactive)
1 = on (active)
Hysteresis of 1% is applied for both High and Low
limit switch. While the limit switch of high side stays
ON, it turns to OFF again only when the value
of FINAL_POSITION_VALUE becomes smaller
by 1% or less than the value of LIMSW_HI_LIM.
Also, while limit switch of low side stays ON, it
turns to OFF again only when the value of FINAL_
POSITION_VALUE becomes greater by 1 % or
more than the value of LIMSW_LO_LIM.

12.4 Auto Tuning
CAUTION
This function strokes the valve over its full range.
Do not execute while valve is controlling the
process. Keep away from the movable parts to
avoid injury.
Auto tuning checks the valve responses and
automatically tunes control parameter settings. The
actions to be performed can be chosen as shown
in the table below (for how to carry out auto tuning,
see Chapter 5, “Setup”). Before carrying out auto
tuning, change the modes of the AO function block
and transducer block to O/S.

IMPORTANT
Auto Tuning in YVP110 sets the 0 % point at the
position where the valve is fully closed and 100%
point at the position where the valve stem stops
against the mechanical stopper(fully open). If it
is necessary to adjust the zero point and span
precisely to the rated stroke of the valve, carry
out travel calibration which is described later in
this chapter after the Auto Tuning.
The result of auto tuning, which is written to AUTO_
TUNE_RESULT, may be an error or warning. An
error invalidates the tuning and does not update the
parameter settings.

12.5 Travel Calibration
CAUTION
This function strokes the valve over its full range.
Do not execute while valve is controlling the
process. Keep away from the movable parts to
avoid injury.
Calibrate the travel of the valve stem, i.e., the stroke
of the valve, as follows. First, set the valve stem
to the desired position by changing the value of
FINAL_VALUE.value. Next, write the value from
the following choices according to your purpose
of calibration. At this time, the AO block and the
transducer block need to be in the O/S mode.
1 = off
2 = 0% point calibration (calibrates only the
0% point and shifts the 100% point by the
resulting amount of the change in 0% point
while leaving the span unchanged).
3 = span calibration (calibrates only the 100%
point while leaving the 0% point unchanged).
4 = 50% point calibration (calibrates at the 50%
point while leaving the 0% point and 100%
point unchanged).
The 50%-point calibration (in other words, linearity
calibration) is intended to minimize the linearity
error at the 50% point. Also, if the feedback lever
is slightly deviates from a horizontal level due to
careless installation of the YVP110 positioner, an
error caused by this shift can be corrected by the
50%-point calibration. Note that carrying out travel
calibration of Index 2 or 3 clears the 50% calibration
result. If you want to carry out the 50%-point
calibration, do it after other tuning has nished.
The result of Travel calibration, which is written to
TRAVEL_CALIB_RESULT as shown in Table 12.3,
may be an error or warning. An error invalidates the
tuning and does not update the parameter settings.
12.6 Online Diagnostics
The YVP110 features functions to diagnose the
YVP110 itself and valve actions during online. The
following describes the self-diagnostics function
related to the transducer block.
12.6.1 XD_ERROR
The transducer block performs self-diagnostics and
writes the results to the parameter XD_ERROR.
Table 12.4 shows the meanings of these results in
XD_ERROR.
When the content of XD_ERROR or BLOCK_ERR
becomes a nonzero value, an alarm is output to the
parameter BLOCK_ALM.

12.6.2 Fail-safe Action
If the “A/D converter failure,” “position sensor
failure,” or “deviation error” event occurs in the
XD_ERROR described above, the transducer block
activates the specied fail-safe action by cutting the
current signal to I/P module to zero. In addition, in
the event of “position sensor failure” or “deviation
error,” the fail-safe action will not be deactivated
even when the cause of the failure/error is
cleared. Writing “Clear non-latch” to the parameter
RELEASE_FAILSAFE will nally deactivate the
fail-safe action in this case. The fail-safe action
activated in the event of “A/D converter failure” will
be deactivated automatically when the cause of the
failure is cleared.
12.6.3 Operation Result Integration
The YVP110 has a function to integrate the
following operation result quantities individually.
To reset an integrated quantity, write 0 to the
corresponding parameter.
• TOTAL_CYCLE_COUNT:
Incremented by 1 at each change in the
direction of the valve action and indicates the
total number of times of changes in direction of
valve actions.
• TOTAL_TRAVEL:
Total travel distance of the stem position shown
as a percentage of the valve position span.
• TOTAL_OPEN_TIME and TOTAL_CLOSE_
TIME:
TOTAL_CLOSE_TIME contains the integrated
time periods (in hours) when the valve position
is equal to or less than the thresholds previously
set in OPEN_CLOSE_THRESHOLD. TOTAL_
OPEN_TIME is the integrated time periods (in
hours) other than TOTAL_CLOSE_TIME.
• TOTAL_NEAR_CLOSE_TIM:
Total time period (in hours) when the valve
position is within the threshold set in NEAR_
CLOSE_THRESHOLD.
• SERVO_WARN_COUNT:
Total number of times the servo output drift
warning occurred.
Indicates the total number of times a drift
warning occurred regarding the output current
to the I/P module.
12.6.4 Recording of Revisions
When the user makes a change to the setting of a
static parameter, the change is counted-up in the
parameter ST_REV and update event is generated.

and can be selected from:
1001 = °C
1002 = °F
A YVP110 with an optional pressure sensor can
measure the output air pressure to the valve
actuator and sets it in the parameter OUT_
PRESSURE. The unit of pressure is dened
by Unit Code in SPRING_RANGE and can be

<13. AO Function Block>
13. AO Function Block
13-1
13.1 General
The AO function block receives the control signal
from the transducer block and outputs it to the
actuator. The major functions of the AO function
block include:
• Scaling
• Setpoint limiters - for both the value and rate of
change
• Simulation
• Valve position feedback
• Actions upon abnormality of upstream block
• Signal inversion
The AO function block performs bi-directional signal
handling: transfer of the valve control signal to the
transducer block (forward path) and feedback of the
valve position signal from the transducer block to
the upstream block (backward path).

13.2 Modes
The target mode for the AO function block can be
set from ve block modes: RCas, Cas, Auto, Man,
and O/S. Regardless of the target mode, the AO
block automatically enters the IMan or LO mode
when a specied condition is met (such as when
another function block enters a specic status)
depending on the parameter settings.
13.3 Forward Path
The following describes the signal input from the
upstream block to the AO block and then passed
to the transducer block. The upstream block is
typically the PID controller block, and the control
signal from the PID block is input as the source of
computing the setpoint SP for the AO block.
The path for computing the SP differs depending
on the mode. In Cas mode, CAS_IN is used for
SP. In RCas mode, RCAS_IN is used for SP. If the
value of CAS_IN or RCAS_IN, whichever is used,
is greater than SP_HI_LIM (high limit) or less than
SP_LO_LIM (low limit), the internal SP is set to the
respective limits. Also, if the rate of change in the
value of CAS_IN or RCAS_IN, whichever is used,
is greater than SP_RATE_UP (rate-of-increase
limit) in the increasing direction, or than SP_RATE_
DN (rate-of-decrease limit) in the decreasing
direction, the change in internal SP is limited by the
corresponding rate-of-change limit setting.
In RCas, Cas or Auto mode, the SP value is used
for the AO block’s output OUT, whose value is then
passed to the transducer block via channel 1.

13.3.1 Fault state
As for Fieldbus-enabled positioners including the
YVP110, not only a power failure but also other
errors (such as a communication error) can cause
the fail-safe action. For example, when the status
of the CAS_IN input of the AO block from its
upstream block indicates a specic status, such as
a communication error, the case is regarded as an
abnormality and fault state actions including a mode
change are enacted.
IM 21B04C01-01E
<13. AO Function Block>
13-2
When any of the following status keeps for the
moment of time specied in FSTATE_TIME, the
block goes to the fault state and the mode changes
to LO mode.
1. Target mode is Cas, and the status of CAS_IN
is ‘Bad: No Comm’
2. Target mode is Cas, and the status of CAS_IN
is ‘Good: IFS’
3. Target mode is RCas, and the status of RCAS_
IN is ‘Good: IFS’
In LO mode, the block holds the output (OUT) or
outputs FSTATE_VAL, according to the setting of
IO_OPTS. The factory setting is to hold the output.
13.4 Backward Path
The valve position signal from the transducer block
is written to the parameter READBACK in the
AO block, then scaled based on XD_SCALE and
PV_SCALE to be converted to the process variable
PV. The value of PV is fed back to the PID block or
an upper-level system as the valve position signal
via the parameter BKCAL_OUT and RCAS_OUT.
If SIMULATE is set to 'Enable', the value of
SIMULATE.Simulate_Value is always set in
READBACK.

NOTE: If a control block is connected as a cascade
primary block of the AO block, a mode transition of the

initialization of the cascade connection: RCas → Auto →
Cas.
13.7 Initialization at Start
To prevent a sudden change in output when the AO
block carries out the specied actions for the rst
time after the power is turned on, it:
1) Equalizes SP to PV if the Faultstate Type option
(bit no. 7) in IO_OPTS is false.
2) Equalizes OUT to READBACK.
If the Faultstate Type option (bit no. 7) in IO_OPTS
is true, it restores FSTATE_VAL in SP.
13.8 Alarm Processing
When a condition shown in the table below is met,
the AO block changes the bit statuses of BLOCK_
ERROR accordingly and generates a block alarm.

14.3 PV Value (PV_D)
A limit switch signal is transferred from the
transducer block via a channel. Normally, the
Transducer Value and Transducer Status values
in SIMULATE_D are copied to FIELD_VAL_D,
indicating the on/off status of the corresponding
limit switch. If SIMULATE_D is set to 'Enable',
the Simulate Value and Simulate Status values in
SIMULATE_D are copied to FIELD_VAL_D.
SIMULATE_D contains the following data:

The OS (output splitter) function block is used
to split a single control signal into two parts for
coordinating the actions of two or more valves, such
as for split-range control or sequencing control of
a large and a small valves. The OS block receives
a control signal and converts it into two signals in
accordance with the predened relationships. The
major functions of the OS block include:
• Conversion of the setpoint (SP) value into
two output values (OUT_1 and OUT_2)
in accordance with the user-specied
characteristics (set in IN_ARRAY and OUT_
ARRAY)
• Generation of the output value to be fed back to

The target mode for the OS function block can
be set from three block modes: Cas, Auto, and
O/S. Regardless of the target mode, the OS
block automatically enters the IMan mode when a
specied condition is met.
In areas outside the endpoints (i.e., start and stop
points) of each operation characteristic, the output
is retained at the Y value at the nearer end point.
For OUT_1, however, depending on the setting of
LOCKVAL, it is possible to:
Set the value of OUT_1 to Y11 in the areas
outside the endpoints if SP is greater than X12
and if LOCKVAL is false.

When this action is enabled, the value set in
HYSTVAL serves as hysteresis, which affects the

<16. PID Function Block>
16. PID Function Block
16-1
16.1 General
The PID function block receives an input signal,
performs PID control computation, and outputs
the control signal, like a single-loop controller. In
practice, it performs PID computation based on
the deviation between the setpoint set in the actual
mode and the PV, and generates a value of its
output OUT so as to decrease the deviation. The
PID block works with other function blocks such as
the AI and AO blocks connected to it. The major
functions of the PID block include:
• Filtering
• Setpoint limiters - both for the value and rate of
change
• Scaling of process variable (PV), setpoint (SP),
and output (OUT)
• PID control computation
• Control action bypass
• Feed-forward
• External-output tracking
• Measured-value tracking
• Output limiters
• Mode shedding upon computer failure
• Alarm generation

16.2 Modes
The target mode for the PID function block can be
set from ve block modes: ROut, RCas, Cas, Auto,
Man, and O/S. Regardless of the target mode,
the PID block automatically enters the IMan or
LO mode when a specied condition is met (such
as when another function block enters a specic
status), depending on the parameter settings.
16.3 Input Processing
The input signal to IN is ltered through a lag lter
whose time constant is set in PV_FTIME, and then
set as the process variable (PV).
OUT
16.4 Setpoint (SP) Limiters
The path for computing the SP differs depending
on the mode. In Cas mode, CAS_IN is used for
SP. In RCas mode, RCAS_IN is used for SP. If the
value of CAS_IN or RCAS_IN, whichever is used,
is greater than SP_HI_LIM (high limit) or less than
SP_LO_LIM (low limit), the internal SP is set to the
respective limits. When the target mode is Auto or
Man, and when SP-PV tracking is not specied at
the same time, the rate of change in the setpoint
is also limited (by the values of SP_RATE_UP and
SP_RATE_DN).
IM 21B04C01-01E
<16. PID Function Block>

16.5 PID Computation
For PID control, the PID block in a YVP110 employs
the PV-proportional and PV-derivative type PID
control algorithm (referred to as the I-PD control
algorithm) for Auto and RCas mode. This algorithm
mensures control stability against sudden changes
in the setpoint, such as when the user enters a new
setpoint value. At the same time, the I-PD algorithm
ensures excellent controllability by performing
proportional, integral, and derivative control
actions in response to changes of characteristics
in the controlled process, changes in load, and
occurrences of disturbances.
For Cas mode, PV-derivative type PID control
algorithm (referred to as the PI-D control algorithm)
is employed in order to obtain better performance
against the changes in the setpoint.
The algorithm is automatically changed by the
block according to the mode. A basic form of each
algorithm is expressed in the equation below.

16.6 Control Output
The nal control output value, OUT, is computed
based on the change in control output ΔMVn, which
is calculated at each control period in accordance
with the aforementioned algorithm. The PID block
in a YVP110 performs the velocity type output
action for the control output. This means that the
PID block determines the value of the new control
output(OUT) by adding the change in control output
calculated in the current control period, ΔMVn, to
the current read-back value of the MV(OUT), MVRB
(BKCAL_IN). This action can be expressed as:
OUT = BKCAL_IN – ΔMVn'
ΔMVn' = ΔMVn which is scaled by PV_SCALE
and OUT_SCALE
16.7 Direction of Control Action
The direction of the control action is determined by
the Direct Acting setting in CONTROL_OPTS.

PV is greater than the setpoint SP.

16.9 Feed-forward
Feed-forward is an action to add a compensation
input signal FF_VAL to the output of the PID control
computation and is typically used for feed-forward
control. In practice, the value of the change in FF_
VAL is scaled to the range of the OUT, multiplied by
the value of FF_GAIN, and then added to the PID
control computation result, as illustrated by Figure
16.4.
When the status of FF_VAL is Bad, the value of
LUV(Lust usable value) is used instead of FF_VAL.
If LUV contains no value, the feed-forward action is

16.11 Measured-value Tracking
Measured-value tracking, also referred to as SP-PV
tracking, is the action of equalizing the setpoint SP
to the measured value PV when the block mode
(MODE_BLK.actual) is Man in order to prevent a
sudden change in control output from being caused
by a mode change to Auto.
While a cascade primary control block is performing
automatic control in Auto or Cas mode, when the
mode of its secondary control block is changed from
Cas to Auto, the cascade connection is opened and
the control action of the primary block stops. The
SP of the primary controller can also be equalized
to its cascade input signal CAS_IN in this case.
The settings for measured-value tracking are made
in the parameter CONTROL_OPTS, as shown in
Table 16.3.

Fallback (IMan)
Initialization and manual fallback denotes a set of
abnormality handling actions in which a PID block
changes mode to IMan (initialization manual) and
suspends the control action. Initialization and
manual fallback takes place only when the following
condition is met:
• The quality component of BKCAL_IN.status
(data status of BKCAL_IN) is Bad.

- AND -
The sub-status component of BKCAL_IN.status
is FSA, LO, NI, or IR.
16.14 Manual Fallback
Manual fallback denotes an abnormality handling
action in which a PID block changes mode to Man
(manual) and suspends the control action.
The manual fallback action is enabled to take place
if the Target to Manual if BAD IN option in STATUS_
OPTS is set as true, and it takes place when the
following condition is met:
• IN.status (data status of IN) is Bad except when
the control action bypass is on.
16.14.1 STATUS_OPTS
16.15 Auto Fallback
Auto fallback denotes an action in which a PID
block changes mode from Cas to Auto and
continues automatic PID control with the user-set
setpoint. To enable the auto fallback action to take
place:
• The Target to next permitted mode if BAD CAS
IN option must be preset to true in STATUS_
OPTS.
- AND -
• Auto must be preset in MODE_BLK.permitted.
If the above settings are made, auto fallback
takes place automatically when the following
condition is met:
• CAS_IN.status (data status of cascade
setpoint) is Bad except when the control action
bypass is on.

Output Parameters (Computation or Selection Results)
OUT: Block output
SELECTED: Indicates the input number selected using the alternatives.
Other Parameters
OUT_RANGE : Sets the OUT range. This setting does not affect instrument action.
STATUS_OPTS : Option used to specify the handling of various statuses.
SELECT_TYPE : Determines the input selection algorithm.
MIN_GOOD : Parameter specifying the minimum required number of inputs with “good” status. If the
number of inputs that are “good” is less than the value of MIN_GOOD, input selection is
canceled.
Mode
O/S : Allows conguration change, but disables input value output.
Man : Allows internal processing, but the output value may vary depending on the denition of usage
conditions.
Auto : Outputs the input value.
The Input Selector (IS) block offers a maximum of eight input alternatives and generates the output according
to the congured action. This block generally receives inputs from the Analog Input (AI) function block. The
function of the IS block is to select a maximum, minimum, middle, average, “rst good,” or “latched good”
signal. The block combines parameter conguration (DISABLE_n) and option (“rst good”) to give priority to
alternative(s) or to function as a rotary position switch. When used as a rotary position switch, the block can
receive operator inputs or switch information from connected inputs.
The IS block supports the concept of middle selection. This function outputs the average of two middle signals
if even multiple valid signals are congured or a middle signal if odd multiple valid signals are congured.
Application of the block is to supply a selected control signal in the forward path.
The SELECTED parameter is the 2nd output indicating which input has been selected using the algorithm.

17.2.2 MIN_GOOD Handling
If there is no selectable input or if the number of selectable inputs is less than the value of MIN_GOOD,
SELECTED becomes “0.”
A case where the number of valid INs is less than the value of MIN_GOOD:
SELECTION
IN_1 = 23
IN_2 = 34.5
IN_3 = 45
IN_4 = 2.34

Figure 17.2 Example (1)
This example restricts the valid inputs using DISABLE_n, and the inputs are enabled only at DISABLE_3 and
DISABLE_5. Because the effective number of MIN_Good is 3, the input specied by OP_SELECT will not be
output.

17.3 Selection
The following processing is performed after completing input processing. If the number of valid inputs is less
than the value of MIN_Good, no input selection is made.
17.3.1 OP_SELECT Handling
When a value other than “0” (that is, 1 to 8) is selected for OP_SELECT:
The IS block selects the input of the number specied by OP_SELECT regardless of the setting of SELECT_
TYPE, propagates the value of that input to OUT, and transmits the input number to SELECTED.

OUT = 45
SELECTED = 3
OP_SELECT = 3
F1703.ai
Figure 17.3 Example (2)
In the above example, SELECT_TYPE is set to Minimum. However, because OP_SELECT species the value
and number of IN_3, the value and number of this specied IN are transmitted to OUT and SELECTED.
* Note: Even if the IN specied by OP_SELECT is an invalid input (the corresponding DISABLE parameter is ON or the IN’s status is
“bad”), the value and status of that IN are transmitted to OUT.

17.3.2 SELECTION Handling
If the value of OP_SELECT is “0,” input selection using SELECT_TYPE is enabled.
When SELECT TYPE is “rst good”
The IS block selects the input with the smallest input number among valid inputs and transmits the value of that
input to OUT. The number of the selected input is transmitted to SELECTED.

Because DISABLE_1 is ON, IN_1 is disabled, and IN_2 is selected for output. If DISABLE_1 is turned OFF,
the output changes from IN_2 to IN_1. That is, the valid IN with the smaller input number is always selected for
output.

When SELECT TYPE is “Middle”
If there is more than one valid input and the number of such input is an odd number, the value of the middle
input will be transmitted to OUT. If there is an even number of valid inputs, the average of the middle two inputs
is transmitted to OUT. If the average is used for OUT, the block transmits “0” to SELECTED, while it transmits
the number of the input used for the middle for other cases. If the number of valid inputs is 1, it is irrelevant to
selection by “Middle” selector action. The following shows an example of selection by “Middle” selector action.
If there is an even number of valid inputs:
Figure 17.7 Example (6)
Because DISABLE_1, DISABLE_2, DISABLE_7, and DISABLE_8 are ON, the corresponding IN_1, IN_2,
IN_7, and IN_8 are disabled and the remaining four INs are enabled. Furthermore, because IN_3 has the
maximum value and IN_4 has the minimum value among the valid INs, they are not selected and the average
of IN_5 and IN_6 inputs is output. When the average is selected for OUT, SELECTED is set to “0.”

When SELECT TYPE is “Latched Good”
The valid input with the smaller input number is selected as an output and is held until it becomes invalid.
When it becomes invalid, the next valid input will be selected as an output regardless of the magnitude of the
value. Even if an input with the input number smaller than that of the currently selected input recovers, the
current selection is held.
Assuming that IN_2 is the valid input with the smallest input number, the order of input selection is IN_2 →
IN_3 → ...→ IN_8 → IN_1 → ....
If the power is turned OFF and then ON with SELECT TYPE set to “Latched Good,” input selection starts with
the IN that was selected before the power was turned OFF.

17.4 Output Processing
17.4.1 Handling of SELECTED
For the value output to SELECTED when OP_SELECT has been selected (that is, not “0”), the number
specied by OP_SELECT will be stored as is.
However, “0” is stored in the SELECTED in the following cases:
1. If there is no valid input;
2. If the value of MIN_GOOD is greater than the number of valid inputs;
3. If the input status is “bad” or “uncertain” when the value of OP_SELECT is anything other than “0”
(with the exception of the case where the “Uncertain as good” bit in STATUS_OPTS is set.);
4. If the value of OP_SELECT is greater than 8, which is the maximum number of inputs;
5. If the value is out of the SELECT_TYPE setting range when the value of OP_SELECT is zero.
As long as there is one valid input, even an invalid input can be selected for OP_SELECT.
If the number of valid inputs is greater than the value of MIN_GOOD, the number of the input (including an
invalid input) specied by OP_SELECT will be stored in SELECTED. Therefore, even if an invalid input is
selected, SELECTED does not become zero.
If no input is selected for OP_SELECT, the output of SELECTED will depend on SELECT_TYPE.
The Table 17.1 shows the value of SELECTED according to the number of valid inputs and SELECT_TYPE.

17.5 Application Example
The following describes the temperature control
system of a xed bed-type reactor. In this case,
there are instances where the point showing the
maximum temperature changes due to catalytic
deterioration, raw material ow, etc. Therefore, a
large number of measurement points are provided,
and the maximum value obtained among these
measurement points is input to the controller to
control reactor temperature.
Basic operations and work sequence:
1. The IS block obtains values and status
information from AI.
2. The block selects the AI information using the
alternatives.
3. The block displays and outputs the information
selected by SELECTED.

The Arithmetic block is divided into three sections:
• Input section: Makes a go/no-go decision on the use of an input value, switches the range, and determines
the PV status.
• Computation section: Makes calculations through ARITH_TYPE.
• Output section: Applies gain multiplication and bias addition to the calculated result to perform limitation
processing for output.
* The range extension function compensates the IN and IN_LO input values when two devices with different ranges are connected, to
make smooth input switching.
