A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 17mmmmmInstallationAir Purging System (Optional)For more frequent cleaning, a purging system can be installed between the flange and the horn antenna. The system provides an 1/8” inlet (female thread) on the flange where cooling air or cleaning fluid passes through the flange and exits the inside of the horn to clean it. The customer will supply the purging medium by a manual or automatic valve system. This option is only available with the universal flange for purging shown on page 17. 1)• The purge connection is closed by the manufacturer, using a 1/8” plug. • When the plug is removed to connect a purging system, the operator is responsible for ensuring that the purging circuit conforms to “Ex” requirements: for example, by fitting an NRV valve. 2)3)Notes: • The Air Purge feature should not be activated with a dust cap in place.• Purge duration, pressure, and interval, will vary with each application. It is the user’s responsibility to determine the requirements depending on the application and cleaning required.• Short duration bursts of high pressure provide more effective cleaning than continuous low pressure air.• Some dust particles are highly abrasive and can be drawn into the inside of the horn during purge cleaning, damaging the internal PTFE emitter of the antenna. A replacement kit is available from your local Siemens Milltronics representative.• It is the customer’s responsibility to ensure that any vacuum or pressure in the measured vessel is maintained, considering the hole that passes through the process connection and SITRANS LR260 antenna system.

A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 103mmmmmD: Technical ReferenceAppendix D: Technical ReferencePrinciples of Operation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of solids and liquids1). Radar level measurement uses the time of flight principle to determine distance to a material surface. The device transmits a signal and waits for the return echo. The transit time is directly proportional to the distance from the material. Pulse radar uses polarized electromagnetic waves. Microwave pulses are emitted from the antenna at a fixed repetition rate, and reflect off the interface between two materials with different dielectric constants (the atmosphere and the material being monitored). Electromagnetic wave propagation is virtually unaffected by temperature or pressure changes, or by changes in the vapor levels inside a vessel. Electromagnetic waves are not attenuated by dust.SITRANS LR260 consists of an enclosed electronic circuit coupled to an antenna and process connection. The electronic circuit generates a radar signal (25 GHz) that is directed to the horn.The signal is emitted from the horn, and the reflected echoes are digitally converted to an echo profile. The profile is analyzed to determine the distance from the material surface to the reference point on the instrument. This distance is used as a basis for the display of material level.Echo ProcessingProcess IntelligenceThe signal processing technology embedded in Siemens radar level devices is known as Process Intelligence.Process intelligence provides high measurement reliability regardless of the dynamically changing conditions within the vessel being monitored. The embedded Process Intelligence dynamically adjusts to the constantly changing material surfaces within these vessels.Process Intelligence is able to differentiate between the true microwave reflections from the surface of the material and unwanted reflections being returned from obstructions such as seam welds or supports within a vessel. The result is repeatable, fast and reliable measurement. This technology was developed as result of field data gained over some twenty years from more than 1,000,000 installations in many industries around the world.1) The microwave output level is significantly less than that emitted from cellular phones.
Page 104 SITRANS LR260 (PROFIBUS PA)– OPERATING INSTRUCTIONS A5E32337685mmmmmD: Technical ReferenceHigher order mathematical techniques and algorithms are used to provide intelligent processing of microwave reflection profiles. This “knowledge based” technique produces superior performance and reliability.Time Varying Threshold (TVT) CurvesA Time Varying Threshold (TVT) curve hovers above the echo profile to screen out unwanted reflections (false echoes). In most cases the material echo is the only one which rises above the default TVT curve. In a vessel with obstructions a large false echo may rise above the default TVT. The Auto False Echo Suppression feature (see below) can be used to screen it out.The device characterizes all echoes that rise above the TVT as potential good echoes. Each peak is assigned a rating based on its strength, area, height above the TVT, amongst other characteristics. The true echo is selected based on the setting for the Echo selection algorithm [Algorithm (2.2.3.1.1.)]. Echo LockIf the echo selected by Algorithm is within the Echo Lock window, the window is centered about the echo, which is used to derive the measurement.•Echo Lock Off: SITRANS LR260 responds immediately to a new selected echo (within the restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is affected.Echo Position DetectionThe echo position algorithm (2.2.3.1.3. Position) determines which point on the echo will be used to calculate the precise time of flight, and calculates the range using the calibrated propagation velocity (adjusted by a propagation factor, if necessary). The options are Center or CLEF (Constrained Leading Edge Fit), Hybrid, or Rising Edge. CLEF uses the leading edge of the echo. It can be used to compensate for materials with High Cal.

CLEF range is the level below which the CLEF algorithm will be used: above this level the Center algorithm is used. Center of Mass selects the center of the echo for evaluation. Rising Edge selects the rising edge of the echo. Hybrid uses a combination of Center and CLEF, depending on the setting for CLEF range.Auto False Echo SuppressionIf an obstruction is causing a large echo before the material level echo, that echo will rise above the default TVT curve and may be selected as the true echo. Auto False-Echo Suppression modifies the TVT curve so that the false echo will not rise above the TVT curve. When you use Auto False Echo Suppression, the device first learns the echo profile at that moment1). A learned TVT curve follows the echo profile and rises above the false echo. You set Auto Suppression Range so that the learned profile replaces the default TVT curve up to a point past the obstruction. From that point on, the default TVT curve is used. The material level echo rises above this, and is selected as the true echo.Measurement RangeNear Range2.2.3.5.1. Near Range programs SITRANS LR260 to ignore the zone in front of the antenna. The default blanking distance is 50 mm (1.97") from end of horn antenna.Near Range allows you to increase the blanking value from its factory default. But 2.2.4.3. Auto False Echo Suppression (AUTO ECHO SUPP) is generally recommended in preference to extending the blanking distance from factory values.1) Use Auto False Echo Suppression when the material level is substantially lower than pro-cess full level (ideally when the tank is empty or almost empty).Example after Auto False Echo Suppression learned TVT curve levelLevel (db)false echo echo marker
Page 106 SITRANS LR260 (PROFIBUS PA)– OPERATING INSTRUCTIONS A5E32337685mmmmmD: Technical ReferenceFar RangeIn applications where the base of the vessel is conical or parabolic, a reliable echo may be available below the vessel empty distance, due to an indirect reflection path. Increasing the range extension to 30% or 40% can provide stable empty vessel readings.Measurement ResponseThe measurement response (Response Rate (1.2.)) limits the maximum rate at which the display and output respond to changes in the measurement. Once the real process fill/empty rate (m/s) is established, a response rate can be selected that is slightly higher than the application rate. The response rate automatically adjusts the filters that affect the output response rate. There are three preset options: slow, medium, and fast.DampingA damping filter smooths out the response to a sudden change in level. This is an exponential filter and the engineering unit is always in seconds. The setting can be modified in Filter Time Constant (FILTER TIME CONST) (2.3.1.4.).Loss of Echo (LOE)A loss of echo (LOE) occurs when the calculated measurement is judged to be unreliable because the echo confidence value has dropped below the echo confidence threshold.

LOE Timer the LCD displays the Maintenance Alarm icon, and the text region displays the fault code S: 0 and the text LOE.If two faults are present at the same time, the fault code, error text, and error icon for each fault are displayed alternately. For example, Loss of Echo and Temperature Sensor Failure. S: 0 LOE S: 11 Temp. Sensor FailureLOE (Loss of Echo) TimerLOE Timer determines the time to elapse after the last valid reading before a Fail-safe state is activated. Fail-safe Material Level determines the level to be reported when the Fail-safe timer expires. Upon receiving a reliable echo, the loss of echo condition is aborted, the Service Required icon and error message are cleared, and the reading return to the current level.Fail-safe ModeThe purpose of the Fail-safe setting is to put the process into a safe mode of operation in the event of a fault or failure. The value to be reported in the event of a fault is selected so that a loss of power or loss of signal triggers the same response as an unsafe level. Fail-safe mode may be triggered by a loss of echo, a bad configuration, or certain device faults. You can select on of three possible values to be reported when a Fail-safe mode is activated.Fail-safe valueWhen the LOE Timer (2.4.1.) expires, the material level to be reported is determined by Fail-safe Mode. If the option Use substitute value is selected, a user-defined value can be reported.The two Analog Input Function blocks are set separately. For example, to set a user-defined value for AIFB1:•Set Fail-safe Mode FB1 (FS MODE FB1) (2.4.2.) to Use substitute value.•Go to Fail-safe Value FB1 (FS VALUE FB1) (2.4.3.) and enter the desired value.Material level to be reportedOptionsSubstitute value (Default value used as output value).* Last value (Store last valid output value).Use bad value (Calculated output value is incorrect).

Standard profile parameters are used to program the level transducer block. Block Model for recording and processing measured valuesThe functions of the device are divided into blocks for different areas of responsibility. They can be parameterized by acyclic data transfer via PDM.The device is implemented with one Physical Block (PB1), one Level Transducer Block (LTB1), and two Analog Input Function Blocks (AIFB1 and AIFB2).All data is viewed from the perspective of the DCS or PLC, so information from the sensor is an input.Transducer Block (TB)The Level Transducer Block (LTB) carries out adjustments to the sensor, such as level calibration. It supplies the outputs utilized by either or both of the AIFBs.Analog Input Function Blocks AIFB1 and AIFB2The two AIFBs are completely independent of each other. They utilize the output from the Level TB, and apply any required quality checks, scaling, and Fail-safe operation selections. The output of an Analog Input Function Block supplies the measured value and associated status information to PROFIBUS PA, via cyclic data transfer.sensorsensorTransducer Blockelectronics temperatureAnalog Input Function Block2Analog Input Function Block1PROFIBUS PA

The sensor technology block selects the proper echo. For an explanation of sensor technology, see Appendix D: Technical Reference, page 103 onwards. The sensor value (in sensor units) is checked to see if it is within its measuring limits. If the limit is exceeded, this results in a Bad status and the error message Failure in measurement. The sensor value is stored in Sensor Value.The analog signal from the sensor is transformed into a digital signal.A Sensor Offset (default 0) provides compensation if necessary for changes in the sensor.

The LTB provides four possible outputs• Primary Value (PV) / Level/Volume• Secondary Value 1 (SV1) / Level• Secondary Value 2 (SV2) / Distance (sensor units)Electronics temperatureThe transducer block also monitors the internal temperature of the device electronics. If the temperature exceeds permitted limits, it does not change the sensor value, but it does change the status.The permitted limits correspond to those of the permitted ambient temperature. 1) Level Offset (default O) can compensate for specific vessel configurations. 00.511.522.533.544.5Low Calibration Point Sensor Value High Calibration PointLevelHigh Level PointLow Level PointCalibrationLevel ValueHigh Level Point(default: 100%)Sensor Reference Point (flange face)Sensor ValueLow Level Point(default: 0%)LevelLevel Offset1Secondary Value 1Low Calibration PointSensor OffsetHigh Calibration Pointdistance/SV2

Peak indicators1) allow you to check the maximum and minimum temperatures that have occurred.Analog Input Function Blocks 1 and 2The figure below shows how measured values are processed within the two Analog Input Function Blocks (AIFB1 and AIFB2) to produce the device outputs, which are communicated via cyclic transfer to PROFIBUS PA, and displayed on the LCD.Analog Input Function Block function groups (simulation, mode and status)2)How the AIFBs workThe Analog Input Function Blocks allow you to control modifications to the output value (PROFIBUS cyclic data). Output ConversionValues transmitted by the Level TB have a status attached. The decision on what to do with each value is made by the Analog Input Function Block. Device/ Input SimulationThe input can be a simulated value instead of a TB OUT value. This allows the AI block to be tested independently of the characteristics of the environment.Fail-safeIf the status of the Primary Value or Simulation Value is bad, the fault logic can output either the last usable measured value, or a given substitute value.1) Open the menu View – Peak Values.2) The output from the Level Transducer Block can be called the Primary Value (or Secondary Value).

The input value is normalized (Scaling Input) Process Variable range applies to any of the four LTB values. (Units of the Process Variable scale are the same as the units used for the LTB output.) Output units together with Process Variable range determine how the LTB output is converted to whatever units the customer wants.2. The scaling output is applied. For example:3. This value is filtered using a first order filter based on a time constant provided by the user. 4. The status of the Process Variable (input value) is checked. If the status is Bad, a Fail-safe condition occurs. The output is determined by the Fail-safe Mode of the block.5. The target mode parameter allows the entire AI block to be overridden by a Manual Out value.6. The value is checked against the user parameterized warning and alarm limits. (There is an upper and lower warning limit and an upper and lower alarm limit. The unit of the limits corresponds to the unit of the output range. A hysteresis parameter prevents toggling in the Status field of the OUT value.)7.

The address will be reset to 126, and if the address lock was on, it will be disabled.c) Press LEFT Arrow to exit.Operating as a Profile DeviceEvery manufactured PROFIBUS product has a unique PROFIBUS identification number which identifies it to the system. PROFIBUS Profile Standard version 3.01 also defines a Profile Model which can identify a product as a generic profile device on the network. SITRANS LR260 can be identified in one of three ways:Notes:• It is possible to change the device address via a Class 1 master (for example, a PLC) and lock the device address to prevent further changes.• If this Address Lock is on, the PA address cannot be changed. This lock can be disabled only by performing an Address Reset.Device Identification Profile ModelSTD PROFILE Standard Profile (uses generic GSD for 2 AIFB [ident # = 0x9701]* MANUFACTURER Manufacturer-specific (uses Siemens EDD and GSD file, which identifies the LR260 [PROFIBUS PA]) [ident # = 0x8162]STD – AIFB 1 ONLY Standard Profile AIFB 1 only (uses generic GSD for 1 AIFB) [ident # = 0x9700]
A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 121mmmmmG: Communications PADefining the device as Profile-specific as opposed to Manufacturer-specific makes it possible to exchange the device for any other device of the same profile type without changing the GSD file. To set up SITRANS LR260 as a profile device see PROFIBUS Ident Number (PROFIBUS IDENT) (4.4.) on page 85.Configuring a deviceSee Configuring a new device on page 38.Configuring PROFIBUS PA with an S7-300/ 400 PLC1. If SITRANS LR260 is not listed in the STEP 7 device catalog, you can download the DeviceInstall file from the Siemens Milltronics Web site and run it from your computer. Go to https://pia.khe.siemens.com/index.asp?Nr=7427 and click on Downloads.2. Add the SITRANS LR260 “rack”: click on and drag the SITRANS LR260 folder from the hardware catalog.3. Fill the rack with desired modules, by dragging and dropping them from the hardware catalog.4. After configuring PROFIBUS PA in steps 2 and 3, download it to the PLC.5. Add code to the PLC program to read data consistently using the SFC14.Cyclic versus Acyclic DataWhen you request data from a device via PROFIBUS PA, you have two choices. Cyclic data is provided at every bus scan: acyclic data is requested and provided as needed. Input information is always requested at every bus scan and is set up as cyclic data. Configuration information is only needed periodically and is set up as acyclic data.Cyclic DataWhen you configure SITRANS LR260 on the PROFIBUS PA bus, there are two slots available for modules.Slot 0 always transmits AIFB1 information1); slot 1 defaults to Free Place, but can be changed to AIFB2 information. If you do not wish to have data transmitted, then you must use a Free Place module in that slot.Each of the two Analog Input Function Blocks can be set up to return Level, or Distance. Within the function blocks, the values are scaled according to the user requirements (please see Analog Input Function Blocks 1 and 2 on page 116 for details).Note: Each of the slots has to have a module defined in it.1) For more information, please see Analog Input Function Blocks 1 and 2 on page 116.

The variables are the outputs of the function block. The 5th byte is the status word and the list of possible values is given in the chart below. The 5 bytes must be read consistently, in a contiguous chunk: they cannot be read byte by byte, and cannot suffer an interrupt. If you are using an S7-300 / 400, you will need to use SFC14 DPRD_DAT: Read Consistent Data of a Standard DP Slave.Status ByteIn PROFIBUS PA there are two possible types of status byte:•status byte: originally defined in Profile Standard V3.0•condensed status: an alternative status byte defined in Profile Standard V3.01You can choose which type of status byte will be returned, by enabling or disabling Condensed Status Mode (COND.

A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 135mmmmmGlossaryGlossaryaccuracy: degree of conformity of a measure to a standard or a true value.agitator: mechanical apparatus for mixing or aerating. A device for creating turbulence.algorithm: a prescribed set of well-defined rules or processes for the solution of a problem in a finite number of steps.ambient temperature: the temperature of the surrounding air that comes in contact with the enclosure of the device.antenna: an aerial which sends out and receives a signal in a specific direction. There are four basic types of antenna in radar level measurement, horn, parabolic, rod, and waveguide.attenuation: a term used to denote a decrease in signal magnitude in transmission from one point to another. Attenuation may be expressed as a scalar ratio of the input magnitude to the output magnitude or in decibels.Auto False-Echo Suppression: a technique used to adjust the level of a TVT curve to avoid the reading of false echoes. (See TVT.)Auto False-Echo Suppression Distance: defines the endpoint of the TVT distance. (See TVT.) This is used in conjunction with auto false echo suppression.beam angle: the angle diametrically subtended by the one-half power limits (-3 dB) of the microwave beam.beam spreading: the divergence of a beam as it travels through a medium. blanking: a blind zone extending away from the reference point plus any additional shield length.The instrument is programmed to ignore this zone.capacitance: the property of a system of conductors and dielectrics that permits the storage of electricity when potential differences exist between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference, and the unit is a Farad. confidence: describes the quality of an echo. Higher values represent higher quality. Confidence threshold defines the minimum value.damping: term applied to the performance of an instrument to denote the manner in which the measurement settles to its steady indication after a change in the value of the level.dB (decibel): a unit used to measure the amplitude of signals. derating: to decrease a rating suitable for normal conditions according to guidelines specified for different conditions. dielectric: a nonconductor of direct electric current.1)
Page 136 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS A5E32337685mmmmmGlossarydielectric constant (DK): the ability of a dielectric to store electrical potential energy under the influence of an electric field. Also known as Relative Permitivity. An increase in the dielectric constant is directly proportional to an increase in signal amplitude. The value is usually given relative to a vacuum /dry air: the dielectric constant of air is 11.echo: a signal that has been reflected with sufficient magnitude and delay to be perceived in some manner as a signal distinct from that directly transmitted. Echoes are frequently measured in decibels relative to the directly transmitted signal.echo confidence: the recognition of the validity of the echo. A measure of echo reliability.Echo Lock Window: a window centered on an echo in order to locate and display the echo’s position and true reading. Echoes outside the window are not immediately processed.Echo Marker: a marker that points to the processed echo.Echo Processing: the process by which the radar unit determines echoes.Echo Strength: describes the strength of the selected echo in dB above 1 V rms.Echo Profile: a graphical display of a processed echo.false echo: any echo which is not the echo from the desired target. Generally, false echoes are created by vessel obstructions.frequency: the number of periods occurring per unit time. Frequency may be stated in cycles per second.hertz (Hz): unit of frequency, one cycle per second. 1 Gigahertz (GHz) is equal to 109 Hz.horn antenna: a conical, horn-shaped antenna which focuses microwave signals. The larger the horn diameter, the more focused the radar beam.inductance: the property of an electric circuit by virtue of which a varying current induces an electromotive force in that circuit or in a neighboring circuit. The unit is a Henry.microwaves: the term for the electromagnetic frequencies occupying the portion of the radio frequency spectrum from 1 GHz to 300 GHz.multiple echoes: secondary echoes that appear as double, triple, or quadruple echoes in the distance from the target echo.Near Blanking: see Blankingnozzle: a length of pipe mounted onto a vessel that supports the flange. parameters: in programming, variables that are given constant values for specific purposes or processes.polarization: the property of a radiated electromagnetic wave describing the time-varying direction and amplitude of the electric field vector.1) Many conductive liquids/electrolytes exhibit dielectric properties; the relative dielectric constant of water is 80.
A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 137mmmmmGlossarypolarization error: the error arising from the transmission or reception of an electromagnetic wave having a polarization other than that intended for the system.PROFIBUS PA: one of the PROFIBUS family of protocols, specifically tailored for the needs of process industries (PA = Process Automation).propagation factor (pf): where the maximum velocity is 1.0, pf is a value that represents a reduction in propagation velocity as a result of the wave travelling through a pipe or medium.pulse radar: a radar type that directly measures distance using short microwave pulses. Distance is determined by the return transit time.radar: radar is an acronym for RAdio Detection And Ranging. A device that radiates electromagnetic waves and utilizes the reflection of such waves from distant objects to determine their existence or position.range: distance between a transmitter and a target.range extension: the distance below the zero percent or empty point in a vessel. relative permittivity: see dielectric constant.repeatability: the closeness of agreement among repeated measurements of the same variable under the same conditions.shot: one transmit pulse or measurement.speed of light: the speed of electromagnetic waves (including microwave and light in free space. Light speed is a constant 299,792,458 meters per second.two wire radar: a low-energy radar. Can be loop powered, analog, intrinsically safe, or a digital (BUS) transmitter. TVT (time varying threshold): a time-varying curve that determines the threshold level above which echoes are determined to be valid.waveguide antenna: a hollow, metallic tube that transmits a microwave signal to the product target.
