Appendix A Device Data BlocksThe device parameters are listed in the following tables. You can access the parameters by means of the index number. The individual blocks each contain standard parameters, block parameters and manufacturer-specific parameters. If you use the DD based configuration tools as an operating program, input screens are available as a user interface.

General explanatory remarks Object TypeObject type for the parameter value. S Simple variable. R Record. A Array of simple variablesData Type Data type for the parameter value.Name Simple variable or array.DS-n Data structure (Record) of index n.Storage Class Class of memory required S Static. Writing to the parameter changes the static revision counter ST_REV. N Non-volatile parameter which must be remembered through a power cycle, but which is not under the static update code. D Dynamic. The value is calculated by the block, or read from another block.Size Number of octets.

Analogue variable formatThe output of each AI block as well as many variables calculated and available from the different blocks of the transmitter is composed of 5 bytes. The Variable is of 32 bit size in Floating Point format (4 bytes) plus a Status Byte (1 Byte).

Variable format - Floating Point Format IEEE-754Byte n Byte n+1 Byte n+2 Byte n+3

EXPONENT MANTISSA MANTISSA MANTISSA

Example: 40 F0 00 00 (hex) = 0100 000 111 000 000 000 000 000 (binary)Calculation: Value = (-1) S * 2 (Exponent 127) * (1 + Mantissa) Value = (-1) 0 * 2 (129 127) * (1 + 2-1 + 2-2 + 2-3) Value = 1 * 4 * (1 + 0.5 + 0.25 + 0.125) = 7.5

StatusThe Status byte is the fifth byte of any out value and represents the Quality of the variable. Each Transducer and Function Block produces a specific set of Status Bytes.

Device Application Process (DAP) blocks

Resource Block (RB)OverviewThis block contains data that is specific to the hardware that is associated with the resource. All data is modelled as Contained, so there are no links to this block. The data is not processed in the way that a function block processes data, so there is no function schematic. This parameter set is intended to be the minimum required for the Function Block Application associated with the resource in which it resides. Some parameters that could be in the set, like calibration data and ambient temperature, are more appropriately part of their respective transducer blocks. The ITK_VER parameter identifies the version of the Interoperability Tester used by the Fieldbus Foundation in certifying the device as interoperable.

ImportantRefer to the specific Block in order to see which Status bytes it produces

OperationsSavingsIn order to keep a valid device setting to be used as reference when a valid condition has to be recovered in case of wrong operations, it is possible save all the above calibrations as Factory or User calibrations and the complete device configuration.The possible savings are the following and are executed in two steps: Selecting and writing the proper save operation in the RB_SPECIAL_OPERATION Selecting and writing in the RB_RESTART = Special Operations

Save Configuration as Default

When this operation is executed, the complete device configuration is saved as default configuration at which the

device returns when the Reset to Default configuration is executed. After the device has been properly configured,

the user can decide to save it as a default configuration in order to recover it if necessary

Save P-dP Trimming as Factory

The P-dP Sensor calibration/trimming is saved as Factory Calibration. This operation is typically executed in the

Factory after the Sensor has been calibrated to the customer's specified measuring range or, in case the customer

didnt requested any measuring range, at the maximum sensor range

Save Static P Trimming as Factory The Static P Sensor calibration/trimming is saved as Factory Calibration.

Save Sensor Temp Trimming as Factory The Sensor Temp. calibration/trimming is saved as Factory Calibration

Save P-dP Trimming as UserThe P-dP Sensor calibration/trimming is saved as User Calibration. This operation is typically executed by the user

after the Sensor has been calibrated at the desired measuring range.

Save Static P Trimming as User The Static P Sensor calibration/trimming is saved as User Calibration

Save Sensor Temp Trimming as User The Sensor Temp. calibration/trimming is saved as User Calibration

ResetsThe transmitter offers some reset operations executed in two steps: Selecting and writing the proper reset code in the RB_SPECIAL_OPERATION Selecting and writing in the RB_RESTART = Special Operations

Reset Configuration to Default ValuesWhen this operation is executed, the complete device configuration returns to the configuration previously saved

as default configuration.

Reset P-dP Trimming to Factory Return the P-dP Sensor calibration/trimming at the calibration previously saved as Factory Calibration

Reset Static P Trimming to Factory Return the Static Pressure Sensor calibration/trimming at the calibration previously saved as Factory Calibration

Reset Sensor Temp Trimming to Factory Return the Sensor temperature calibration/trimming at the calibration previously saved as Factory Calibration

Reset P-dP Trimming to User Return the P-dP Sensor calibration/trimming at the calibration previously saved as User Calibration.

Reset Static P Trimming to User Return the Static Pressure Sensor calibration/trimming at the calibration previously saved as User Calibration

Reset Sensor Temp Trimming to User Return the Sensor temperature calibration/trimming at the calibration previously saved as User Calibration

Pressure Transducer Block

Physical I/O

Pressure transducer block (PRTB)OverviewThis pressure transducer block is implemented within devices whose primary process sensor has the purpose to measure pressure, or differential pressure (P-dP). In addition, at the pressure value as primary measurement, there are other variables that can be selected trough the Channel as input for the Analog Input blocks, these are the Sensor Temperature, the Static Pressure, for Differential pressure sensors only, and the Scaled PV identified respectively as Secondary, Tertiary and Quaternary variables.

Block diagram

DescriptionThe Physical I/O represents the physical interface with the process and is part of the devices Pressure Transducer. The physical I/O takes care to execute the basic manufacturer device specific algorithm with the purpose to convert the raw signal representing the measured process value into a digital format. The physical I/O operations are: Sampling of the primary raw signal changing according the process changes. Validation and Elaboration of the sampled primary raw signal Linearization and CompensationResult of the above operations is the RAW_VALUES produced in output of the physical I/O, see the Block Diagram, and used as input for the Pressure Transducer Block. The first Pressure Transducer Block operation is the Calibration/trimming of the RAW_VALUES in order to adjust its digital value to match the real pressure measured by the Sensor block.The RAW_VALUES after the calibration became the calibrated Measured Values (MV) represented by the PRTB_CAL_VALUE and, for differential sensors only, PRTB_STATIC_P_TRIM_VALUE.These Measured Values matches and represents the real inputs sampled by the sensor and any further calculation has the scope to transform them to a Process Variables (PV). In this perspective the first calculation applied is the elevation/suppression within the PV-Bias/Offset step executed for different rea-sons like the correction of the mounting position or for example in any condition where part of the measure must not be considered as part of the process.



EquationsOnce the MV and PV are calculated and available in the PRTB then it can produces different type of measurements depending by the selected PRTB_QUATERNARY_LIN_TYPE and applying the following formula:Measurement Type QUATERNARY_LIN_TYPE Formula

Transfer functionThe transfer output functions available in the 266 Pressure Transducer Block are described in details Linear for differential, gauge and absolute pressure or level measurements Sq. Root (x) for flow measurements using restriction type primary element, like orifice plate, integral orifice, Venturi or Dall tube and similar. Sq. Root (x3) for open channel flow measurements using rectangular or trapezoidal weir Sq. Root (x5) for open channel flow measurements using V-notch (triangular) weir. Bidirectional Flow Custom linearization table Cylindrical lying tank Spherical tankThese output functions can be selected writing in PRTB_QUATERNARY_LIN_TYPE activated using a DD based Configuration Tool. The transfer function can be applied to the Process Variable only or also to the indication (in engineering units).

LinearUsing this function, the relationship between the input (measured value), expressed in % of the calibrated span and the output is linear (i.e.: at 0% input, corresponds 0% output - at 50% input corresponds 50% output - and at 100% input corresponds 100% output). No further settings are possible here

Square rootUsing the Square Root function, the output (in % of the span) is proportional to the square root of the input signal in percentage of the calibrated span (i.e.: the instrument gives an analog output proportional to the rate of flow). The possibility to have the full Square Root function is given. To avoid the extremely high gain error with the input approaching zero, the transmitter output is linear with the input up with a slope of 1 up to 0.5% and then still linear with the appropriated slope to a programmable percentage value between 10 % and 20%. This option is offer in order to ensure a more stable output when the signal is close to zero avoiding errors due to the high gain of the square root. To neglect the values with the input approaching zero, the transmitter output is zero with the input up to a programmable percentage value between 0 % and 20%. This option is offer in order to ensure a more stable flow measure. This option is possible for all the listed output functions.

Square root to the 5th powerThe x5 Square root Transfer function can be used for open channel flow measurement using ISO 1438 Vnotch (triangular) weirs (see figure on the right) where the relationship between the flow and the developed head h (the differential pressure measured by the transmitter) is proportional to h5/2 or square root of h5.Using this function, the output (in % of the span) is proportional to the square root of the fifth power of the input signal in % of the calibrated span: the instrument (it gives an output proportional to the rate of flow calculated using the Kingsvater-Shen formula).

Bidirectional Flow The bidirectional function, applied to the transmitter input (x) expressed in percentage of the calibrated span, has the following form: Output = + sign (x) x where x and Output should be normalized in the range 0 to 1 for calculation purpose, with the following Output meaning: Output = 0 means Analog out 4 mA; Output = 1 means Analog out 20 mA.This function can be used for flow measurement purpose when the flow is in both the directions and the primary elements are designed to perform this type of measure.As an example, if we have a bidirectional flow measurement application with the following data: Max reverse flow rate: -100 l/h Max flow rate: +100 l/hThe differential pressure generated by the flow primary is for the maximum flow rate 2500 mmH2O, for the max reverse flow rate 2500 mmH2O. The transmitter will have to be configured as follows: Calibrated span: 4mA = LRV = -2500mmH2O 20mA = URV = +2500mmH2OTransfer function: Bidirectional flow. Once configured as above the transmitter will deliver: flowrate 100 l/h reverse: output= 4mA no flowrate: output= 12mA Flow rate 100 l/h: output= 20mA

Cylindric lying tank This function is used to measure the volumetric level into a cylindrical horizontal tank with flat ends. The transmitter calculates the volume from the measured filling level.

Spherical Tank This function is used to measure the volumetric level into a spherical tank. The transmitter calculates the volume from the measured filling level.

Square root to the 3rd powerThe x3 Square root Transfer function can be used for open channel (see figures on the right) flow measurement using ISO 1438 rectangular weirs (Hamilton Smith, Kindsvater-Carter, Rehbock formulas) or trapezoidal weirs (Cippoletti formulas) and ISO 1438 Venturi flumes. In these types of devices the relationship between the flow and the developed head h (the differential pressure measured by the transmitter) is proportional to h3/2 or square root of h3. Other types of Venturi or Parshall flume do not follow this relationship.Using this function, the output (in % of the span) is proportional to the square root of the third power of the input signal in % of the calibrated span: the instrument gives an output proportional to the rate of flow calculated using the above mentioned formulas.

Sensor calibrationThe transmitter makes available to the user some operations that can be useful during the device life cycle. These operations are supported and can be executed with the EDD based configuration tools, or also by following the instructions/descriptions below.

Sensor trimming/calibrationThe scope of the sensor trimming/calibration is to adjust and make accurate as much as possible the sensor conversion to a pressure value in digital format.The sensors of the 266 are calibrated/trimmed in the factory to the customers specified measuring range therefore it could be necessary change or correct the sensor calibration later on as maintenance operation.Two points are necessary to perform a sensor calibration. Low sensor calibration point (Zero) writing in PRTB_CAL_POINT_LO and High sensor calibration point (Span) writing in PRTB_CAL_POINT_HI. The minimum distance from the two points must be greater than minimum span PRTB_CAL_MIN_SPAN.

P-dP sensor low trimmingWith this operation the PRTB_CAL_VALUE is automatically adjusted, in order to match the real value of the pressure applied in input, in the low part of the working range. The following sequence of operations is required: Apply a reference pressure in input using a reference pressure generator. Select the engineering unit of the measure in the PRTB_CAL_UNIT (Pressure Unit Only) Read the measure produced by the transmitter from the PRTB_CAL_VALUE. If this value doesnt match the pressure applied in input, enter the correct known applied pressure value in the PRTB_CAL_POINT_LO and write to the transmitter. This writing executes an internal algorithm that produces the new correction coefficients. Read again the PRTB_CAL_VALUE and check if its value now matches the applied pressure.

P-dP sensor high trimmingWith this operation the PRTB_CAL_VALUE is automatically adjusted, in order to match the real value of the pressure applied in input, in the high part of the working range. The following sequence of operations is required: Apply a reference pressure in input using a reference pressure generator. Select the engineering unit of the measure in the PRTB_CAL_UNIT (Pressure Unit Only) Read the measure produced by the transmitter from the PRTB_CAL_VALUE. If this value doesnt match the pressure applied in input, enter the correct known applied pressure value in the PRTB_CAL_POINT_HI and write to the transmitter. This writing executes an internal algorithm that produces the new correction coefficients. Read again the PRTB_CAL_VALUE and check if its value now matches the applied pressure.

Static pressure low trimming With this operation the PRTB_STATIC_P_TRIMMED_VALUE is automatically adjusted, in order to match the real value of Static Pressure applied at the transducer in the lower part of the range. The following sequence of operations is required: Select the engineering unit of the measure in the PRTB_STATIC_P_CAL_UNIT (Pressure Unit Only) Read the Static Pressure value from the PRTB_STATIC_P_TRIMMED_VALUE.


If this value doesnt match the known Static Pressure applied in input at the transducer, enter the correct value in the PRTB_STATIC_P_CAL_POINT_LO and write to the transmitter. This writing executes an internal algorithm that produces the new correction coefficients. Read again the PRTB_STATIC_P_TRIMMED_VALUE and check if its value now matches the real Static Pressure value coefficients.

Static pressure high trimming (for piezo dP sensor only) With this operation the PRTB_STATIC_P_TRIMMED_VALUE is automatically adjusted, in order to match the real value of Static Pressure applied at the transducer in the upper part of the range. The following sequence of operations is required: Select the engineering unit of the measure in the PRTB_STATIC_P_CAL_UNIT (Pressure Unit Only) Read the Static Pressure value from the PRTB_STATIC_P_TRIMMED_VALUE. If this value doesnt match the known Static Pressure applied in input at the transducer, enter the correct value in the PRTB_STATIC_P_CAL_POINT_HI and write to the transmitter. This writing executes an internal algorithm that produces the new correction coefficients. Read again the PRTB_STATIC_P_TRIMMED_VALUE and check if its value now matches the real Static Pressure value.

Sensor temperature trimmingWith this operation the PRTB_SECONDARY_VALUE (Sensor Temperature) is automatically adjusted, in order to match the real value of the sensor temperature. The following sequence of operations is required: Select the engineering unit of the temperature in the PRTB_SECONDARY_VALUE_RANGE_UNIT (Temperature Unit Only) Read the Sensor Temperature value from the PRTB_SECONDARY_VALUE. If this value doesnt match the known Sensor Temperature of the transducer, enter the correct value in the PRTB_SENSOR_TEMP_CAL_POINT and write to the transmitter. This writing executes an internal algorithm that produces the new correction coefficients. Read again the PRTB_SECONDARY_VALUE and check if its value now matches the real Sensor temperature value.

Parallel shift (P-dP)In case the process (dp or p) cannot be led to 0 it is possible correct the measure performing the Parallel Shift operation. Typically this operation is applicable for Level measurements. Having the possibility to see/read the actual measure in percent, if it is not what expected, enter the percent of what the process should measure. The correction consists in the shift of the calibration range values PRTB_PRIMARY_VALUE_RANGE 0% and PRTB_PRIMARY_VALUE_RANGE 100% in order to produce in output the measure, PRTB_QUATERNARY_VALUE at the desired percentage. The parallel shift is executed by writing the desired percent value in the PTRB_PARALLEL_SHIFT_PV.

ImportantAfter the parallel shift execution, the percent value of the PRTB_QUATERNARY_VALUE matches the desired percentage only if the PRTB_LIN_TYPE is set

to Linear. If an AI block is set to CHANNEL = 4 it receives in input the PRTB_QUATERNARY_VALUE and in this case the AI_OUT matches the desired

percentage as well only if the AI_L_TYPE is set to Linear

This makes it possible to set the output signal of several measuring devices that measure the same process variable to the same value without having to perform a calibration with applied pressure. E.G. the transmitter output can be adjusted to gauge-glass for level measurement. This function can - under the following circumstances - be carried out at any point on the characteristic: Process variable within the adjusted measuring range - transmitter with linear transfer function. Write protection on the transmitter must not be activated.



When a pressure px is applied, the transmitter displays the standardized output value x1 in percent. Due to the present application the value x2 should be displayed. Enter this new value x2 in the line PRTB_ PARALLEL_SHIFT_PV, the transmitter calculates the new zero and the new final value and adopts these new settings in the PRTB_PRIMARY_VALUE_RANGE 0% and PRTB_PRIMARY_VALUE_RANGE 100%

Advanced diagnostic transducer block (ADTB)OverviewThe advanced diagnostic transducer block contains some historic/statistical information and all the parameters related with the PILD algorithm. The goal of this block is to supervise the device and set diagnostic alarms under transducer abnormal condition to the control system modifying the pressure transducer block primary value status and raising the proper alarm bit in the ADTB_BLOCK_ERR and RB_MAINTENANCE_ACTIVE.
