Appendix A – Device Data Blocks

The 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 Type

Object type for the parameter value.

S – Simple variable. R – Record. A – Array of simple variables

Data 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 format

The 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).

Device Application Process (DAP) blocks

Resource Block (RB)

Overview

This 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.

Pressure Transducer Block

Physical I/O

Pressure transducer block (PRTB)

Overview

This 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

Description

The Physical I/O represents the physical interface with the process and is part of the device’s 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 Compensation Result 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 reasons 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.

Transfer function

The 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 tank These 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).

Linear

Using 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 root

Using 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

Figure 45: Linear output

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 3rd power

The 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.

Figure 47: Tanks (respectively rectangula weir, trapezoidal weir and V-notch weir)

Square root to the 5th power

The 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 = ½ + ½ sign (x) ∙ x ½ 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/h The 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 = +2500mmH2O Transfer 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

Sensor calibration

The 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/calibration

The 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 customer’s 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 trimming

With 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 doesn’t 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 trimming

With 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 doesn’t 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.

16 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters

Page 17

– If this value doesn’t 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 doesn’t 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 trimming

With 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 doesn’t 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.

Important

After 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.

Advanced diagnostic transducer block (ADTB)

Overview

The 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.

Block diagram

Description

The Plugged Impulse Line Detection (PILD) is a function aimed at detecting the blockage of the process connections of the instrument and any type of problem occurring at the sensor internal hydraulic circuit. The PILD algorithm is executed in two distinct phases:

Training phase:

Selecting ADTB_PILD_COMMAND = TRAIN the training phase starts analyses and learns the process dynamics in term of noises of the primary signal detected when the process is working at its normal conditions. The Training Phase can take long time depending by the PILD settings of ADTB_PILD_TRAIN_TIME, ADTB_PILD_RETRIES……, then if the training phase is successfully completed with good result, ADTB_PILD_TRAINING_OUTPUT = PILD_TRAIN_OK the PILD pass to the second phase of process monitoring otherwise it is possible read from the ADTB_PILD_TRAINING_OUTPUT the possible cause like: – Process Instable during training – Process not available during training – Not good process condition for training – Training not done

Monitoring phase:

The algorithms perform a continuous sampling and comparison of the current process noises with what memorized during the training phase. Differences have been experienced being consequences of something bad in process connections to the sensor like dirty, ice and so on which tap/plug the pipe/s partially or totally. Whenever a pipe plugging/tapping is detected, the ADTB_PILD_OUTPUT that was set to NORMAL during the monitoring phase changes to one of the following conditions:

18 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters

Page 19

– Line on side H plugged – Line on side L plugged – Both lines H and L plugged – An undeﬁned line plugged

In this case also the device diagnosis is affected setting the bit Pild_Output in the RB_MAINTENANCE_ACTIVE and the speciﬁc bit of the above detailed 4 info in the RB_EXTENDED_ACTIVE. When one of the above conditions has been detected, there is the possibility that the process variables in output from the PRTB continue to be produced with GOOD status. In this way the AI blocks receiving in input the variables from the PRTB works normally and the operator could have not evidence of the wrong conditions. For this reason it is possible make a choice in order to decide to affect or not the PRTB variables when the plugging conditions have been detected. This selection is possible with the ADTB_PILD_AFFECT_PV variable. When it is selected to true, and the Plugging conditions are detected, the GOOD status that would be produced in output for the PRTB_PRIMARY_VALUE, PRTB_SECONDARY_VALUE, PRTB_TERTIARY_VALUE, PRTB_QUATERNARY_VALUE are all forced to BAD status. The PILD algorithm loses the train every time it is switched off. The algorithm is switched off automatically for every error condition, except when the pressure violates the maximum pressure deviation and the retrain is selected.

Historical/statistical info

From this block can be also read the Minimum and Maximum values measured by the transducer of Pressure, Static Pressure and Sensor Temperature plus the total working time and the number of device power cycles. These information can allow the user to do detailed/speciﬁc diagnostic analysis and evaluations.

HMI transducer block (HMITB)

Overview

The display transducer block is an independent block dedicated to the management of the local display and the local operations via push buttons.

Block diagram

Description

The HMI Transducer Block contains all the parameters allowing the display conﬁguration. Refer also to section 10 of OI/266/FF manual.

24 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters

In this case the PRTB_PRIMARY_VALUE is calculated with the selected

HMI_LIN_TYPE and the result ready to be scaled with the HMI_VARIABLE_

RANGE.

SQRT 5° pow

In the Block Object data structure, there are different items describing the block characteristics. Execution period, Number of

parameters in the block, the DD Revision, Proﬁle Revision, View Objects characteristics and so on

The revision level of the Static data associated with the Function Block. The revision level is incremented each time a static

parameter value (S – under Storage) in the block is changed.

S AUTO / OOS The selectable modes by the operator.

This parameter reflects the error status associated with the hardware or software components associated with a

block. It is a bit string, so that multiple errors may be shown.

Bit 15 = Out of Service The MODE_BLK_ACTUAL = Out of Service.

The block alarm is used for all conﬁguration, hardware, and connection failure or system problems in the block. The cause of the

alert is entered in the sub-code ﬁeld. The ﬁrst alert to become active will set the Active Status in the status parameter. As soon

as the Unreported status is cleared by the alert reporting task, another block alert may be reported without clearing the Active

Status, if the sub-code has changed.

Device diagnostic

The 266 PdP FF produces different type of diagnostic information: – Device Diagnostic These are the diagnostic information produced by the Resource and Transducer Blocks and refer to the device status/health – Process Diagnostic These are the diagnostic information which are seen through process variable status and process alarms such as the HI, HI HI, LO, LO LO, DV HI and DV LO alarms implemented in various Function blocks Scope of this section is to describe the Device Diagnostic to be used by the Asset Management Software.

Standard errors

The FF standard parameter deﬁning the device diagnostic conditions is the BLOCK_ERR contained by each block and mapped as follow:

Bit 2 Link Configuration Error

Bit 3 Simulate Active

Bit 4 Local Override

Bit 11 Lost NV Data

Bit 12 Readback Check Failed

Bit 13 Device Needs Maintenance Now

Bit 14 Power Up

Bit 15 Out of Service

Field Diagnostic Proﬁle (NAMUR NE107)

The device diagnostic info are split into four different alert type parameters relating the four NAMUR NE107 categories, they are: – RB_FAIL_ACTIVE – RB_OFFSPEC_ACTIVE – RB_MAINTENANCE_ACTIVE – RB_CHECK_ACTIVE The 4 bit-string parameters are mapped in the same way but each error condition became set only within one of the four parameters. For some error conditions, the bit mapped within the 4 parameters above is not clear enough for the maintenance person to get the root of the problem, for this reason it has been deﬁned an additional parameter RB_EXTENDED_ACTIVE with additional detailed information about the speciﬁc error condition. Only the errors without details mapped in the RB_x_ACTIVE and all the RB_EXTENDED_ACTIVE errors can be simulated from the RB_DIAGNOSIS_SIMULATION.

Important

Only one condition/bit per time can be simulated.

Important

Critical error conditions cannot be masked.

The RB_SIMULATION_STATUS must be enabled before to simulate any individual error condition. The same parameter can be read with the scope to clarify if an error condition is active because simulated or calculated. Some of the error bits mapped in the RB_x_ACTIVE can be masked from the RB_DIAGNOSIS_MASK.

Enhanced-Analog Input Function Block (E-AI)

Overview

The Analog Input receives in input variables produced in the Transducer Block via the selected CHANNEL. It is possible that some transmitters have more Transducer Blocks or more variables produced within one Transducer Block. The CHANNEL setting allows the user to select the desired variable to be used in input for the AI.

Block diagram

Description

Transducer scaling (XD_SCALE) is applied to the value from the channel to produce the FIELD_VAL in percent. The XD_SCALE units code must match the channel units code (if one exists), or the block will remain in O/S mode after being configured. A block alarm for units mismatch will be generated. The OUT_SCALE is normally the same as the transducer, but if L_TYPE is set to Indirect or Ind.Sqr.Root, OUT_SCALE determines the conversion from FIELD_VAL to the output. PV and OUT always have identical scaling. OUT_SCALE provides scaling for PV. The PV is always the value that the block will place in OUT if the mode is Auto. If Man is allowed, someone may write a value to the output. The status will prevent any attempt at closed loop control using the Man value, by setting the Limit value to Constant. The LOW_CUT parameter has a corresponding “Low cut-off” option in the IO_OPTS bit string. If the option bit is true, any calculated output below the low cut-off value will be changed to zero. This is only useful for zero based measurement devices, such as flow. The PV filter, whose time constant is PV_FTIME, is applied to the PV, and not the FIELD_VAL.

Equations

The Analog Input receive in input the Transduce Block variable Value selected with the CHANNEL. The Input Value is represented as CHANNEL Value in the following formula.

FIELD_VAL = 100 *

CHANNEL_VALUE – XD_SCALE_0% XD_SCALE_100% – XD_SCALE_0%

Depending by the L_TYPE selection the following signal conversions are applied:

L_TYPE Formula

Direct PV = CHANNEL_VALUE

Indirect

Indirect Square Root

This conversion is applied when the XD_SCALE values are different from the OUT_SCALE values

PV = FIELD_VAL% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%

IF FIELD_VAL < 0.0

PV = OUT_SCALE 0%

ELSE IF FIELD_VAL < LOW_CUT

PV = OUT_SCALE 0%

ELSE PV = √ Field_Val% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%

Configuration hints

The minimum configuration for having the AI working and/or moving out from the OOS needs at least the following settings: – CHANNEL different by 0 (uninitialized) – XD_SCALE = OUT_SCALE – L_TYPE = Direct ** The minimum configuration can be set also via the RB_SPECIAL_RESTART

Enhanced-PID function block (E-PID)

Overview

The PID block is key to many control schemes and is used almost universally, with the exception of PD, which is used when the process itself does the integration. As long as an error exists, the PID function will integrate the error, which moves the output in a direction to correct the error. PID blocks may be cascaded when the difference in process time constants of a primary and secondary process measurement makes it necessary or desirable. The PID receives in input the value produced in output from an upstream function block like Analog Input, and provides to apply the algorithm with the Proportional, Integral, Derivative contribute as previously conﬁgured.

Block diagram

Description

The Process Value to be controlled is connected to the IN input. This value is passed through a ﬁlter whose time constant is PV_FTIME. The value is then shown as the PV, which is used in conjunction with the SP in the PID algorithm. A PID will not integrate if the limit status of IN is constant. A full PV and DV alarm sub-function is provided. The PV has a status, although it is a Contained parameter. This status is a copy of IN’s status unless IN is good and there is a PV or block alarm. The full cascade SP sub-function is used, with rate and absolute limits. There are additional control options which will cause the SP value to track the PV value when the block is in an actual mode of IMan, LO, Man or ROut. Limits do not cause SP-PV tracking. There is a switch for BYPASS, which is available to the operator if the Bypass Enable control option is true. Bypass is used in secondary cascade controllers that have a bad PV.

2600T Series Pressure transmitters | OI/266/FF/ADD-EN Rev. B 41

Page 42

266 Models - FOUNDATION Fieldbus

The Bypass Enable option is necessary because not all cascade control schemes will be stable if BYPASS is true. BYPASS can only be changed when the block mode is Man or O/S. While it is set, the value of SP, in percent of range, is passed directly to the target output, and the value of OUT is used for BKCAL_OUT. When the mode is changed to Cas, the upstream block is requested to initialize to the value of OUT. When a block is in Cas mode, then on the transition out of bypass, the upstream block is requested to initialize to the PV value, regardless of the “Use PV for BKCAL_OUT” option. GAIN, RESET, and RATE are the tuning constants for the P, I, and D terms, respectively. Gain is a dimensionless number. RESET and RATE are time constants expressed in seconds. There are existing controllers that are tuned by the inverse value of some or all of them, such as proportional band and repeats per minute. The human interface to these parameters should be able to display the user’s preference. The Direct Acting control option, if true, causes the output to increase when the PV exceeds the SP. If false, the output will decrease when the PV exceeds the SP. It will make the difference between positive and negative feedback, so it must be set properly, and never changed while in an automatic mode. The setting of the option must also be used in calculating the limit state for BKCAL_OUT. The output supports the feed forward algorithm. The FF_VAL input brings in an external value which is proportional to some disturbance in the control loop. The value is converted to percent of output span using the values of parameter FF_SCALE. This value is multiplied by the FF_GAIN and added to the target output of the PID algorithm. If the status of FF_VAL is Bad, the last usable value will be used, because this prevents bumping the output. When the status returns to good, the block will adjust its integral term to maintain the previous output. The output supports the track algorithm. There is an option to use either the SP value after limiting or the PV value for the BKCAL_OUT value.

Equations

The algorithm applied is as in the following formula:

OUT = GAIN[(BETA · SP – PV) +

Where the standard variables are:

GAIN: Proportional Gain Value RESET: Integral action Time constant in seconds s: Laplace operator RATE: Derivative action time constant in seconds FF_VAL: Feed-forward contribution from the feed-forward input SP: Setpoint PV: Process Variable

Configuration hints

The minimum conﬁguration for having the PID working and/or moving out from the OOS needs at least the following settings: – OUT_HI_LIM > OUT_LO_LIM – SP_HI_LIM > SP_LO_LIM – BYPASS = OFF – SHED_OPT = Normal Shed Normal Return – GAIN > 0

Description

The AR block is intended for use in calculating measurements from combinations of signals from sensors. It is not intended to be used in a control path, so it does not support control status propagation or back calculation. It has no process alarms. The block has 5 inputs. The ﬁrst two are dedicated to a range extension function that results in a PV, with status reﬂecting the input in use. The remaining three inputs are combined with the PV in a selection of four term math functions that have been found useful in a variety of measurements. The inputs used to form the PV should come from devices with the desired engineering units, so that the PV enters the equation with the right units. Each of the additional inputs has a bias and gain constant. The bias can be used to correct for absolute temperature or pressure. The gain can be used to normalize terms within a square root function. The output also has gain and bias constants for any further adjustment required. The range extension function has a graduated transfer, controlled by two constants referenced to IN. An internal value, g, is zero for IN less than RANGE_LO. It is one when IN is greater than RANGE_HI. It is interpolated from zero to one over the range of RANGE_LO to RANGE_HI. The equation for PV follows:

PV = g * IN + (1-g) * IN_LO

If the status of IN_LO is unusable and IN is usable and greater than RANGE_LO, then g should be set to one. If the status of IN is unusable, and IN_LO is usable and less than RANGE_HI, then g should be set to zero. In each case the PV should have a status of Good until the condition no longer applies. Otherwise, the status of IN_LO is used for the PV if g is less than 0.5, while IN is used for g greater than or equal to 0.5. An optional internal hysteresis may be used to calculate the status switching point. Six constants are used for the three auxiliary inputs. Each has a BIAS_IN_i and a GAIN_IN_i. The output has a BIAS and a GAIN static constant. inputs, the bias is added and the gain is applied to the sum. The result is an internal value called equation for each auxiliary input is the following:

Input selector function block (AR)

Overview

The signal selector block provides selection of up to four inputs and generates an output based on the conﬁgured action. This block normally receives its inputs from AI blocks. The block performs maximum, minimum, middle, average and ‘ﬁrst good’ signal selection. With a combination of parameter conﬁguration options the block can function as a rotary position switch, or a validated priority selection based on the use of the ﬁrst good parameter and the disable_n parameter. As a switch the block can receive switching information from either the connected inputs or from an operator input. The block also supports the concept of a middle selection. Although the normal conﬁguration for this feature would be with three signals the block should generate an average of the middle two if four signals are conﬁgured or the average of two if three are conﬁgured and a bad status is passed to one of the inputs. Logic is provided for handling uncertain and bad signals in conjunction with conﬁgured actions. The intended application of this block is to provide control signal selection in the forward path only, therefore, no back calculation support is provided. SELECTED is a second output that indicates which input has been selected by the algorithm.

Block diagram

Description

This block is intended to be used in a forward path only and is not intended to receive signals from the output of a controller. There is no back calculation support or propagation of control status values. The processing of the block is as follows.

Input processing

If DISABLE_n is true then don’t process (ignore) the respective input IN_n. Process the Use Uncertain as Good status options. Discard (ignore) inputs whose status is BAD. If there are no inputs left, or fewer than MIN_GOOD inputs, then set the value of SELECTED to zero. Do not do selection processing.

Selection Processing

If OP_SELECT is non-zero, the OP_SELECT value shall determine the selected input, regardless of the SELECT_TYPE selection. Set SELECTED to the number of the input used. If SELECT_TYPE is First Good, transfer the value of the ﬁrst remaining input to the output of the block. Set SELECTED to the number of the input used.

2600T Series Pressure transmitters | OI/266/FF/ADD-EN Rev. B 53

Page 54

266 Models - FOUNDATION Fieldbus

If SELECT_TYPE is Minimum, sort the remaining inputs by value. Transfer the lowest value to the output of the block. Set SELECTED to the number of the input with the lowest value. If SELECT_TYPE is Maximum, sort the remaining inputs by value. Transfer the highest value to the output of the block. Set SELECTED to the number of the input with the highest value. If SELECT_TYPE is Middle, sort the remaining inputs by value. If there are 3 or 4 values, discard the highest and lowest value. If two values are left, compute their average. Transfer the value to the output of the block. Set SELECTED to zero if an average was used, else set SELECTED to the number of the input with the middle value. If SELECT_TYPE is Average compute the average of the remaining inputs and transfer the value to the output of the block. Set SELECTED to the number of inputs used in the average.

Limit Processing

The computations to determine high and low limit conditions for the output can be complex. They should be done to the best of the designer’s ability. The limits of OUT should be able to tell a PID to stop integrating if the measurement cannot move.

Equations

With the SELECT_TYPE it is possible select the following algorithms

First Good Select the first available Input with Good Status

Minimum Select the minimum value of the Inputs

Maximum Select the maximum value of the Inputs

Middle Calculate the middle of three inputs or the average of the two middle inputs if four inputs are defined

Average Calculate the average value of the inputs

Conﬁguration hints

The minimum conﬁguration for having the IS working and/or moving out from the OOS needs at least the following settings: – Set the SELECT_TYPE with a valid value. It must be different by 0 and in the range 1 – 5.

Control Selector function block (CS)

Overview

The control selector block is intended to select one of two or three control signals in a manner determined by SEL_TYPE, when the block is in Auto mode. A different block, described in Part 3, is used for selecting a measurement from input or calculation blocks.

Block diagram

Description

All inputs to the selector block are assumed to have the same scaling as OUT, since any one of them may be selected to be OUT. Three separate BKCAL_SEL_N outputs are available, one for each SEL_N input. The status will indicate those inputs that are not selected. Control blocks that are not selected are limited in one direction only, determined by the type of selector. The value of each BKCAL_SEL_N output is the same as OUT. The limits of back calculation outputs corresponding to deselected inputs will be high for a low selector and low for a high selector, or one of each for a mid selector.

Equations

With the SEL_TYPE it is possible select the following algorithms:

1. High

2. Low

3. Middle

Conﬁguration hints

The minimum conﬁguration for having the CS working and/or moving out from the OOS needs at least the following settings: – Set the SEL_TYPE with a valid value. It must be different by 0 and in the range 1 – 3

Signal Characterizer function block (SC)

Overview

The signal characterizer block has two sections, each with an output that is a non-linear function of the respective input. The non-linear function is determined by a single look-up table with 21 arbitrary x-y pairs. The status of an input is copied to the corresponding output, so the block may be used in the control or process signal path. An option can swap the axes of the function for section 2, so that it can be used in the backward control path.

Block diagram

Description

The block calculates OUT_1 from IN_1 and OUT_2 from IN_2 using a curve given by the points: [x1 ;y1 ], [x2 ; y2 ] ... [x21 ; y21 ] where x corresponds to the Input and y to the Output. The x-coordinates are given in engineering units of X_RANGE. The y-coordinates are given in engineering units of Y_RANGE. The only useful mode is Auto.

Calculation and the curve:

OUT_1 is related to IN_1 and OUT_2 to IN_2 by the same curve, but there is no relation between IN_1 and IN_2 or between OUT_1 and OUT_2. An output value may be calculated by linear interpolation between two points bracketing the input value. Values of x should increase monotonically, so that interpolation may be possible.

2600T Series Pressure transmitters | OI/266/FF/ADD-EN Rev. B 61

Page 62

266 Models - FOUNDATION Fieldbus

If not, a conﬁguration error shall be set in BLOCK_ERR and the actual mode of the block shall go to Out of Service. Write checks may also be implemented, but they may force the order of entry of the x terms. If the curve has m points, m<21, the non-conﬁgured points, [xm+1; ym+1], [xm+2; ym+2], ... [x21; y21] shall be set to +INFINITY to mark them as unused. Since x1 is the smallest speciﬁed value for the input and xm is the largest, the output shall be at y1 when the input is smaller than x1 and at ym when the input is larger than xm. Since the ends of the y curve act as limits, the OUT status shall show when either limit is active.

Reversing path 2:

A reverse function swaps the interpretation of IN_2 and OUT_2, which provides a way to do back calculation using the same curve. If the parameter SWAP_2 is set true, the block shall provide: IN_1 = x and OUT_1 = y while IN_2 = y and OUT_2 = x If the function is not monotonic in y and SWAP_2 is true, then BLOCK_ERR shall indicate a conﬁguration error and the actual mode go to Out of Service as above for x. A function is called monotonic when y values always increase or decrease when x values increase, e.g. the function does not present peaks, valleys, or ﬂat spots. If SWAP_2 = false, IN_1 and IN_2 have the same engineering units deﬁned in X_RANGE and OUT_1 and OUT_2 use the units deﬁned in Y_RANGE. If SWAP_2 = true, OUT _1 and IN_2 have Y_RANGE and OUT_2 and IN_1 have X_RANGE.

Configuration hints

The minimum conﬁguration for having the SC working and/or moving out from the OOS needs at least the following settings: – Set SWAP_2 different by 0 – Set at least one X and Y pairs – Set the X values monotonically increasing or the Y values monotonically increasing or decreasing

Integrator function block (IT)

Overview

The Integrator Function Block integrates a variable as a function of the time or accumulates the counts from a Pulse Input block (to be described in another speciﬁcation). The block may be used as a totalizer that counts up until reset or as a batch totalizer that has a setpoint, where the integrated or accumulated value is compared to pre-trip and trip settings, generating discrete signals when these settings are reached. The integrated value may go up, starting from zero, or down, starting from the trip value. The block has two ﬂow inputs so that it can calculate and integrate net ﬂow. This can be used to calculate volume or mass variation in vessels or as an optimizing tool for ﬂow ratio control. In order to determine the amount of uncertain or bad readings, the block integrates the variables with bad or bad and uncertain status separately. The values used in this second integration are the values with good status just before they went from good to bad or uncertain. The ratio of good to total counts determines the output status. Absolute values are used to avoid problems with changing signs.

Block diagram

2600T Series Pressure transmitters | OI/266/FF/ADD-EN Rev. B 65

Page 66

266 Models - FOUNDATION Fieldbus

Description

The function of this block is in keeping with common industry practice. There is nothing to be tested here concerning the calculation of the integral term. The following description is a guide to the use of the parameters. The basic function of the Integrator block is to integrate an analog value over time. It can also accumulate the pulses coming from Pulse Input blocks or from other Integrator blocks. This block is normally used to totalize ﬂow, giving total mass or volume over a certain time, or totalize power, giving the total energy.

Inputs

The block has two dual purpose inputs, IN_1 and IN_2. If IN_2 is not connected (does not have a corresponding link object) then calculations for IN_2 may be omitted. Each input can receive a measurement per unit of time (rate) or an accumulated number of pulses. The usage is as follows: – Rate: used when the variable connected to the input is a rate, i.e., Kg/s, w, Gal/hour, etc. This input can come from the rate output OUT of a Pulse Input block or from the output of an Analog Input block. – Accum: used when the input comes from the OUT_ACCUM output of a Pulse Input block, which represents a continuous accumulation of pulse counts from a transducer, or from the output of another Integrator block. The input type is conﬁgured in the bit string parameter INTEG_OPTS. The bits corresponding to IN_1 and IN_2 can be set false for Rate or true for Accum.

If the input option is Rate:

Each input needs a parameter to deﬁne the rate time unit: TIME_UNIT1 or TIME_UNIT2. The time units are used to convert the two rates in units of mass, volume or energy per second The second analog input may have to be converted into the same units of the ﬁrst input. This is achieved by a unit conversion factor, given by the parameter UNIT_CONV. Each rate, multiplied by the block execution time, gives the mass, volume or energy increment per block execution. This increment should be added or subtracted in a register, according to some rules deﬁned below. The following diagram is an example of the use of two Rate inputs:

66 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters

Page 67

If the input option is Accum:

A counter input normally comes from a Pulse Input block OUT_ACCUM. It can also be connected to the output of another integrator block. The OUT_ACCUM of the Pulse Input block represents a continuous accumulation of pulses from the ﬂow transducer, while the output OUT of an Integrator represents an integration or accumulation of analog inputs. The Integrator block should determine the number of additional counts from the counter input readings since the last execution. As the output ACCUM_OUT of the Pulse Input block wraps up when the counting reaches 999,999 and does not increment or decrement by more than 499,999 per cycle, the difference in counts is determined as follows: – If the difference between the reading in one cycle and the reading in the preceding cycle is less than 500,000 or greater than (-500,000), the difference should be taken as the variation. – If the difference between the reading in one cycle and the reading in the preceding cycle is greater than or equal to (+500,000), add (-1,000,000) and use the result as the variation. – If the difference between the reading in one cycle and the reading in the preceding cycle is more negative than or equal to (-500,000), add (+1,000,000) and use the result as the variation. If the output OUT of another integrator block is used, that block should be programmed to obey the rules listed above. The variation of each input should be multiplied by the value, in engineering units, of each pulse given by PULSE_VAL1 or PULSE_ VAL2, as appropriate. The result is the increment in engineering units of, for example, mass, volume or energy per block execution (please see diagram below).

Net Flow

In order to discern between forward and reverse ﬂows, the Integrator block considers a negative sign as an indication of reverse ﬂow. Some ﬂowmeters already indicate forward and reverse ﬂows by adding a sign to the measurement value. Others use a separate binary signal. This signal can be connected to the inputs REV_FLOW1 and REV_FLOW2, where True should invert the signal of the corresponding input. The net ﬂow is obtained by adding the two increments. The net increment should have a positive or negative signal to indicate the net ﬂow direction. In order to integrate the difference between the inﬂow and outﬂow of a tank, for example, the second one can be assigned to be negative. The net ﬂow direction to be considered in the totalization is deﬁned in INTEG_OPTS. The following options are available: FORWARD = only positive ﬂows (after application of REV_FLOWi ) are totalized. The negative values should be treated as zero. FORWARD is selected when the bit corresponding to Forward is set to true. REVERSE = only negative ﬂows are totalized. The positive values should be treated as zero. The option bit Reverse should be set to true TOTAL = both positive and negative values should be totalized. Both option bits Forward and Reverse should be set to true or to false.

Integration of Inputs:

There are three internal registers used for the totalization: Total = The net increment is added every cycle, regardless of status. Atotal = The absolute value of the net increment is added every cycle, regardless of status. Rtotal = The absolute value of the net increments with bad status (rejects) are added to this register. These internal registers may have greater precision than the standard ﬂoating point value. The value of Rtotal requires the same precision as Atotal in order to be able to accumulate ﬂoating point fractions so that they are not lost as arithmetic underﬂow. The value of a register that corresponds to standard ﬂoating point is called the most signiﬁcant part of the register. The most signiﬁcant part of Total can be read in the output OUT, and of Rtotal in RTOTAL. OUT_RANGE is used only for display of the totals by a host. The

high and low range values of OUT_RANGE have no effect on the block.

Types of integration:

The value of OUT can start from zero and go up or it can start from a Setpoint value (TOTAL_SP) and go down. Reset may be automatic, periodic, or on demand. This is deﬁned by the enumerated parameter INTEG_TYPE: – UP_AUTO Counts up with automatic reset when TOTAL_SP is reached – UP_DEM Counts up with demand reset – DN_AUTO Counts down with automatic reset when zero is reached – DN_DEM Counts down with demand reset – PERIODIC Counts up and is reset periodically according to CLOCK_PER – DEMAND Counts up and is reset on demand – PER&DEM Counts up and is reset periodically or on demand The ﬁrst four types indicate use as a batch totalizer with a setpoint TOTAL_SP. This is not the standard SP because it does not have the structure of SP that is deﬁned in FF-890. The count does not stop at TOTAL_SP going up or zero going down, as it is important to get the true total of ﬂow. Two outputs, OUT_TRIP and OUT_PTRIP, are associated with the four types. See Batch totalizer outputs below. The next three types indicate that TOTAL_SP and the trip outputs are not used. The Periodic type (5) disables operator reset. The internal registers always add the net increments. Counting down is done by setting OUT to the value of TOTAL_SP minus the most signiﬁcant part of Total.

Resetting the totals:

The block shall use a discrete input RESET_IN to reset the internal integration registers. The operator can send an operator command to reset the same registers by making OP_CMD_INT = RESET. This is a momentary switch, which shall be turned off when the block is evaluated. Either shall cause reset to occur. Reset should occur after the totals have been adjusted in the same block evaluation. The block should take a snapshot of the most signiﬁcant part of Total, Rtotal and TOTAL_SP just prior to the reset and move the values to the registers STOTAL, SRTOTAL and SSP, respectively. The information should be kept until the next reset. The integrator should reject reset requests for at least 5 seconds after a reset. This is to allow time for other devices to read the snapshot values before they can be overwritten. The option Conﬁrm Reset in INTEG_OPTS, if set, prevents another reset from occurring until the value 1 has been written to RESET_CONFIRM. This is an Input that behaves like a momentary dynamic parameter if it is not connected. This provides a guarantee that a host has recorded the snapshot values before the next reset can occur. The number of resets is counted in the register N_RESET. This counter can not be written or reset. It provides veriﬁcation that the total has not been reset since N_RESET was last checked. The counter should roll over from 999999 to 0. Reset always clears the internal registers Total, Atotal and Rtotal, except that when the option UP_AUTO or DN_AUTO is selected, a residual value beyond the trip value may be carried to the next integration if the option Carry is set in INTEG_OPTS. In this case, TOTAL_SP is subtracted from Total, leaving the residual value. The option Generate reset event in INTEG_OPTS shall cause an analog event (DS-75) to be generated at each reset. This messages provides a timestamp and the most signiﬁcant part of Total just prior to the reset. The Standard Type (4.3) shall be 14, Reset event. The Subcode (4.8) shall be the status byte of OUT. The Value (4.9) shall be the most signiﬁcant part of Total just prior to the reset. The Unit Index (4.11) shall be the units code of OUT_RANGE.

Batch totalizer outputs:

When the integration is counting up (type 1 or 2) and the value of OUT equals or exceeds a value given by TOTAL_SP minus PRE_TRIP then the discrete output OUT_PTRIP is set. When it equals or exceeds a value given by the parameter TOTAL_SP, the discrete output OUT_TRIP is set. OUT_PTRIP remains set. When the integration is counting down (type 3 or 4), it starts from a value given by TOTAL_SP. When the value of OUT is equal to or less than PRE_TRIP, the discrete output OUT_PTRIP is set. When the count reaches zero, the discrete output OUT_TRIP is set. OUT_PTRIP remains set. When a reset occurs, the comparisons that set OUT_PTRIP and OUT_TRIP are no longer true, so they are cleared. OUT_TRIP shall remain set for ﬁve seconds after an automatic reset (type 1 or 3) if RESET_CONFIRM is not connected or the option to Conﬁrm Reset in INTEG_OPTS is not set.

Conﬁguration hints

The minimum conﬁguration for having the IT working and/or moving out from the OOS needs at least the following settings: – Set TIME_UNIT1 different by 0 – Set TIME_UNIT2 different by 0 – Set INTEG_TYPE different by 0

See the OUT STATUS section below

NOTE A: The speciﬁc block cannot be switched out from OUT OF SERVICE due to the Conﬁguration Error. The Bad-Conﬁguration Error Status is overridden by the Bad-Out Of Service Status.

OUT status

If an input has a status of Uncertain or Bad, it shall be treated as explained below. The limit status of the inputs is ignored, as is the substatus. Either Good(C) or Good(NC) are accepted as good. The increment calculated from an input has an internal status that is either good or bad. If the input status is Good(C) or Good(NC) the increment status is good. If the input status is Uncertain, the increment status is bad, and the last good value is used unless the option Use Uncertain is set in INTEG_OPTS, and then the increment status is good and the new value is used. If the input status is Bad, the increment status is bad, and the last good value is used unless the option Use Bad is set in INTEG_OPTS, and then the increment status is good and the last good value is used. The two increments are added together, and the resulting status is the worst of the two. The option Add zero if bad in INTEG_OPTS causes the net increment to be zero if its status is bad. The percentage of bad or uncertain and bad counts may be determined by calculating the value of PCT_INCL from Rtotal and Atotal. Since Atotal is the sum of increments with good and bad status, and Rtotal is the sum of increments with bad status, Atotal minus Rtotal is exactly equal to the total of increments with good status. If msp is used to mean “most signiﬁcant part” and Atotal is not zero then the percent of good values may be calculated as: PCT_INCL = 100 * ( 1 - (msp of Rtotal) / (msp of Atotal) ) If Atotal is zero, then PCT_INCL shall be 100 if Rtotal is also zero, or 0 if Rtotal is not zero. If the block mode is Auto, if PCT_INCL ≥ GOOD_LIM, the status of OUT shall be Good, or else if PCT_INCL ≥ UNCERT_LIM, the status of OUT shall be Uncertain, or else the status of OUT shall be Bad. If the block mode is Manual, then the status of OUT, OUT_PTRIP, and OUT_TRIP will be Good (NC) constant when then status option Uncertain if Man is not selected. If this status option is selected and the block mode is manual, then the status of these three outputs will be Uncertain constant. No limits are applied to the output.

Appendix C – Device Conﬁguration/Setting through FF communication

When the 266 PdP transmitter has to be used in a FF project and/or connected to any type of Host, the first operation is to import in the Host the DD and CF files of the device. The DD and CF files can be downloaded from the ABB website www.abb. com/intrumentation or from the FF organization website www.fieldbus.org under Registered Products When the DD and CF files has been imported in the Host then: – All the device blocks are visible and it is possible access at their parameters for operations like configuration/parameterization, maintenance, monitoring by reading or writing the parameters mapped in the transmitter’s blocks and addressed via index – The device can be instantiated in a network design and its Function Blocks can be instantiated into a Function Block Application (FBAP) for the plant control strategy.

Commissioning

Once the transmitter has been installed, it is put into operation by switching on the operating voltage. Check the following before switching on the operating voltage: – Process and electrical connections – The impulse line/s and the measuring chamber of the measuring equipment must be completely filled with the measuring medium. The transmitter can then be put into operation. To do this, the shut-off valves must be actuated in the following sequence (in the default setting, all valves are closed):

(Differential models) 266Dx or 266Mx

– Open the shut-off valves on the pressure tap connection (if present). – Open the pressure equalization valve of the manifold. – Open the positive shut-off valve (on the manifold). – Open the negative shut-off valve (on the manifold). – Close the pressure equalization valve. To put the transmitter out of operation, carry out the steps in reverse order.

84 OI/266/FF/ADD-EN Rev. B | 2600T Series Pressure transmitters

Page 85

(Gauge & Absolute models) 266Gx, 266Ax, 266Hx, 266Nx, 266Px, 266Vx, 266Rx

– Open the shut-off valve on the pressure tap connection (if present). – Open the positive shut-off valve. To put the transmitter out of operation, carry out the steps in reverse order.

Important

In case of the 266 transmitter for absolute pressure (266Vx, 266Rx, 266Ax and 266Nx) with a measuring range less than or equal 650 mbar abs., please

be aware that the measuring equipment will have been overloaded by the atmospheric pressure due to the long periods of transport and storage involved.

For this reason, you will need to allow a starting time of approx. 30 minutes for 266Vx, 266Rx and 266Nx models and 3 hours for 266Ax models after

commissioning, until the sensor has stabilized to such an extent that the speciﬁed accuracy can be maintained.

Correction of the mounting position

During installation of the transmitter, zero shifts caused by mounting (e.g., a slightly oblique mounting position due to a remote seal, etc.) may occur; these must be corrected.

Important

The transmitter must have reached its operating temperature (approx. 5 min. after startup, if the transmitter has already reached the ambient temperature).

This correction can be executed only if the Calibration Lower Range value is 0.0 and must be made with process (dp or p) = 0. The correction consists in the Zero elevation/suppression operation and can be done in two ways: – Locally by acting on the Z push button when the electronic switch SW 3 is set to 0 – From remote station via FF communication writing 0.0 in the PTRB_DESIRED_PRIMARY_VALUE In case the Calibration Lower Range value is not 0.0 then the correction cannot be made with the local Z push button but it can be done in the following way: – From remote station via FF communication writing the correct measure value in the PTRB_DESIRED_PRIMARY_VALUE

Important

After the above operations the Calibration Range Values are not changed. The desired process output value is produced through an internal calculation by

applying an offset at the measured value

Initialization

The 266 PdP implements up to three Analog Input Blocks, 2 of Enhanced category and 1 Standard. Each AI produce in output one variable (AIx_OUT) suitable to be linked to other downstream function blocks. The three AIs receive in input one of the variables produced by the Pressure Transducer Block depending by their own AIx_CHANNEL setting. The default AIx_CHANNEL setting is: – The Analog Input 1 receives in input the PRTB_PRIMARY_VALUE (Process Pressure) through the AI1_CHANNEL = 1. – The Analog Input 2 receives in input the PRTB_TERTIARY_VALUE (Static Pressure) through the AI2_CHANNEL = 3. – The Analog Input 3 receives in input the PRTB_SECONDARY_VALUE (Sensor Temperature) through the AI3_CHANNEL = 2. Hovewer all the 3 AIx_CHANNEL can be switched to receive in input up to different 4 PRTB variables:

Appendix D – 266 PdP Fieldbus FOUNDATION electronics replacement

In order to perform the replacement of a Fieldbus FOUNDATION electronic module, please follow the steps listed here below: – Remove the cover of the electronics/display side. – Remove the display (if installed) and be careful to the plastic clips of the electronic module. – Remove the 2 ﬁxing screws from the electronic module. – Extract the electronics from the housing, and disconnect the ﬂat cable that links the sensor primary electronics to the communication board.

– Take the new electronics and put the switch 1 in UP position (1) since it enables the Replacement operation. It must be used in combination with the SW 2. – Put dip switch 2 in OFF position (0) selects the Electronics Replacement. The entire transmitter’s configuration data are kept valid in the sensor memory and copied into the memory of the new electronics once it is connected. – Connect the sensor ﬂat cable to the new electronics and insert it into the housing (be careful with the two in-housing jack connectors). – Power on the transmitter and keep it powered-on for few seconds (at least 30). – Power-Off the transmitter again, and put the switch 1 and 2 in OFF (0) position. – Fix the electronics with the two screws. – Insert the display, (be carefully with the 6 pins connector). Maybe removing again the electronics from the housing make easier the connection of the display.

– Mount the display cover again. The operation is completed and the device will run with default conﬁguration: PD_TAG = PI000 ADDRESS = 248
