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 conguration are indicated on the nameplate. Verify that the conguration indicated in the “Model and Sufx Code” in Chapter 7 is in compliance with the specications 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 satises 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 inuence 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 (sufx

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 specied value.

3. The voltage at the specied 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 conrmed (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 conrm 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 specically 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 specication of Lo and Co in the

certicate 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

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 Specications.”

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.

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 performs the adjustment. For details, consult the control valve manufacturer.

(2) Fixing the YVP110 to Actuator with Bracket

After xing the bracket to the YVP110, attach it to the actuator with the specied 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 specications of the levers shown in Table 3.1 and Figure

3.2 and choose the lever most suitable for the control valve used.

When /LV1 is specied, the hardware for attaching the lever to the feedback shaft and the spring for xing the clamp pin are attached to the F9176HA, the smaller feedback lever for generally used mid-capacity actuators. Thus, when using the F9176HC, the feedback lever for high-capacity actuators, detach and use the hardware and spring from the F9176HA. See Figure 3.4. To do so, rst detach the spring <4>. Then, detach the clip <1> and remove the hardware <2> and <3>. Attach <1> to <4> to the F9176HC feedback lever for highcapacity actuators in the reverse order.

When determining which lever to use, follow the procedure below to make a linkage between the YVP110 positioner and control valve’s stem via the clamp and lever. The adjustment of this linkage is a decisive factor for determining the characteristics of the control valve combined with the YVP110 positioner.

(1) Insert the YVP110’s feedback shaft into the

small hole on the stopper side of the lever as shown in Figure 3.5.

(1) Allowable Range of Rotation Angle of

Feedback Shaft

When combining a YVP110 with a rotarymotion actuator, ensure that the rotation of the feedback shaft by the position feedback meets the following specications:

• Range of rotation angle of shaft: Within ±45 degrees from horizontal level

• Minimum span: 20 degrees

• Maximum span: 90 degrees

• Mechanically allowable rotation angle: ±55 degrees

If any one or more of the specications above are not met, the specied accuracy may not be guaranteed, resulting in the YVP110 positioner being damaged. An advance check is essential.

(3) Attaching Feedback Lever

For a rotary-motion actuator, since it is often difcult to secure sufcient 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.

(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 specied 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.

4. Wiring and Piping

4-1

4.1 General

This chapter describes the air piping and electric wiring connections.

WARNING

• 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 specied 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 specication can be chosen when ordering the YVP110.

*Applicable only for Double Acting Type

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 sufcient 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 sufciently 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).

F0401.ai

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 specied 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 sufcient 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 proong 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 conrm 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 conguration 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 specied input voltage and air pressure. For the connection to the eldbus, see the chapters 4.3 'Wiring' and 8.4 'System Conguration'.

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 predened 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.

1 = linear-motion actuator 2 = rotary-motion actuator

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 specications 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 specied 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

(static loop gain of internal valve control loop) SERVO_RESET (integral time) SERVO_RATE (derivative time) SERVO_RATE_GAIN (derivative gain) SERVO_DEADBAND

(dead band of integral action) SERVO_OFFSET (offset of integral action) BOOST_ON_THRESHOLD

(threshold to switch on the boost action) BOOST_OFF_THRESHOLD

(threshold to switch off the boost action) BOOST_VALUE SERVO_I_SLEEP_LMT

(timer setting for integral action) SERVO_P_ALPHA

(multiplication coefcient for the square of

proportional factor) INTERNAL_GAIN

(total gain of I/P module,control relay and the

valve)

(the addition value to threshold for switching on boost action for exhaust.)

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.

IM 21B04C01-01E

<5. Setup>

5-4

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.

CAUTION

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

denes 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 = Camex Percentage 255 = user-dened

Writing the value 255 allows you to dene 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 specied 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 denes 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. Maintenance

6-1

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.

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.

SUP

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. About Fieldbus

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 specication 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 Conguration

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 sufciently 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 simplied 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 conguration tool other than the existing host, conrm 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 conguration 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 ofine conguration, use the CFF which matches the specication of the instrument to be congured. 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.

9. Conguration

9-1

This chapter contains information on how to adapt the function and performance of the YVP110 to suit specic 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 denition

Determines the tag and node addresses for all

devices.

(3) Denition 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 modied 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 Conguration' 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 conguration tool allows the procedure to be signicantly simplied. 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 conguration 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 Denition

Before connection of devices with Fieldbus, dene 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 denition. 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.

For other address ranges, the range is 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 specication of each device for details. Table 9.2 lists YVP110 specication values.

9.3 Denition 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 dened 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 specied. 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 congured 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 modication 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 species 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 Block Setting

Set the parameter for function block VFD.

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 species one combination. Each link object has the parameters listed in Table 9.5. Parameters must be changed together for each VCR because the modications made to each parameter may cause inconsistent operation.

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 satised, 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.

Table 10.1 Block Modes

Function Block Modes

Resource Auto, O/S Transducer Auto, O/S AO RCas, Cas, Auto, Man, (LO), (IMan),

O/S DI Auto, Man, O/S OS Auto, Cas, (IMan), O/S PID Rout, RCas, Cas, Auto, Man, (LO),

(IMan), O/S IS Auto, Man, O/S AR Auto, Man, O/S

Modes marked with ( ) in the above table cannot be specied 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-congured 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 specied 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 specied 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.

RCas mode

Means Remote Cascade mode. In RCas mode, the function block performs the specied 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 specied 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 dened 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.

Description

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 specied 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 modied during plant operation by mistake, a hardware switch labeled SIM.ENABLE is provided on the YVP110’s amplier 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 (identied as a Block alarm).

• A static parameter has been written (identied as an update event).

• The value of a write-locked parameter has been modied (identied as Write alarm).

<12. Transducer Block>

12. Transducer Block

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

• Setpoint high/low limiters

• Auto tuning

• Valve tight-shut and full-open actions

• Valve position-to-ow rate characteristics conversion

• Travel calibration

• Diagnostics of valve and positioner

• Valve position limit switches

• 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 specied 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 specications of the valve (in reference with Chapter 5, “Setup”).

<12. Transducer Block>

12-2

12.2.2 Position-to-ow Rate Characteristic Conversion

The parameter POSITION_CHAR_TYPE denes the characteristics between the valve position and ow rate, and can be set to one the following: 1 = linear 2 = equal percent (50:1) 3 = equal percent (30:1) 4 = quick open (reversal of equal percent 50:1) 5 = Camex Percen tage 255 = user-dened

Writing the value 255 allows you to dene 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.

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 notied 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 specic: The deviation exceeds the limit.

12.3.2 Limit Switches

Limit switches monitor whether the valve position has reached a specied 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 specied 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.

12.7 Control Parameters

The following control parameters in a YVP110 can be set up by auto tuning: (For details, see section A6.4) SERVO_GAIN SERVO_RESET SERVO_RATE SERVO_RATE_GAIN SERVO_DEADBAND SERVO_OFFSET BOOST_ON_ THRESHOLD BOOST_OFF_THRESHOLD BOOST_VALUE SERVO_I_SLEEP_LMT SERVO_P_ALPHA INTERNAL_GAIN X_BOOST_ON_THRESHOLD * X_BOOST_OFF_THRESHOLD * X_BOOST_VALUE *

* Applicable only for Double Acting Type

12.8 Temperature and Pressure Measurement

The YVP110 measures the surface temperature of the amplier and sets it in the parameter ELECT_TEMP in the transducer block. The unit of temperature is dened by TEMPERATURE_UNIT 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 dened by Unit Code in SPRING_RANGE and can be selected from: 1133 = kPa 1137 = bar 1141 = psi 1145 = kgf/cm

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 specied condition is met (such as when another function block enters a specic 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 specic 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 specied 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.

13.7 Initialization at Start

To prevent a sudden change in output when the AO block carries out the specied 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.

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:

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 specied condition is met (such as when another function block enters a specic 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 specied 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).

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.

In Auto / RCas mode

∆MVn=K ∆PVn+

In Cas mode

∆T

(PVn−SPn)+

∆T

∆(∆PVn)

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

The direction of the control action is determined by the Direct Acting setting in CONTROL_OPTS.

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 not carried out.

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.

16.13 Initialization and Manual 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.

- OR -

• The quality component of BKCAL_IN.status is Good (c)

- 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.

16.16 Mode Shedding upon Computer Failure

When (1) the data status of RCAS_IN, which is the setting received from a computer as the setpoint SP, falls to Bad while the PID block is running in the RCas (remote cascade) mode, or when (2) the data status of ROUT_IN, which is the setting received from a computer as the remote output signal, falls to Bad while the PID block is running in the ROut (remote output) mode; mode shedding occurs in accordance with the SHED_OPT setting.

17. IS Function Block

The function of the Input Selector (IS) block is to automatically select one signal from multiple input signals using a specied selection method.

The IS block is used for selective control in which one measured quantity is selected from multiple measured quantities to be transmitted to the controller as a controlled variable. This feature is primarily used for temperature control systems.

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 conguration change, but disables input value output. Man : Allows internal processing, but the output value may vary depending on the denition 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 congured 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 conguration (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 congured or a middle signal if odd multiple valid signals are congured. 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.

• Automatic system operation status

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.”

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 specied 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.

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:

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 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 → ....

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 specied 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) specied 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.

If SELECT_TYPE is “Latched Good”

• The previous value is output. (At startup, the initial value is used).

• Writable (the operator may change the value.)

• The previous value is output.

• Not writable

• Zero

• Not writable

• The value of the selected input is output.

• Not writable

• The previous value is output.

• Not writable

• The value of a valid input with the smallest input number is output.

• Not writable

• The minimum value among the values of the valid inputs is output.

• Not writable

• The maximum value among the values of the valid inputs is output.

• Not writable

• Because two inputs are positioned in the middle of the values of even multiple valid inputs, the average of the values of these two inputs is output.

• Not writable

• The value of the input positioned in the middle of the values of odd multiple valid inputs is output.

• Not writable

• The value obtained by dividing the added value of the values of valid inputs by the number of these inputs is output.

• Not writable

• The value of a valid input with the smallest input number is output.

• Not writable

17.4.3 STATUS_OPTS

Bit Description

Use Uncertain as Good

Causes all inputs (OP_SELECT, IN_n, and DISABLE_n) the status of which is “uncertain,” to be handled as “good” (NC) status inputs and the others to be handled as ”bad” status inputs.

Uncertain if Man mode

When the mode is Man, the status of OUT is interpreted as “uncertain.” (This does not apply to SELECTED.)

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.

<18. AR Function Block>

18. AR Function Block

The Arithmetic (AR) block switches two main inputs of different measurement ranges seamlessly and combines the result with three auxiliary inputs through the selected compensation function (10 types) to calculate the output.

18.1 AR Function Block Schematic

The diagram below shows the Arithmetic block schematic.

18-1

F1801.ai

Figure 18.1 AR Block

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.
