Page I- 2 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01mmmmmSITRANS LR 460SITRANS LR 460SITRANS LR 460 is a long-range FMCW radar level transmitter for level measurement of solids. It can be used in high pressure applications or applications requiring gas safety approvals. The Easy Aimer design makes it easy to set up the device even in conditions of extreme dust. The narrow antenna beam creates a sharp emission cone, which makes the LR 460 quite insensitive to vessel interferences.

This will install the GSD file into your system (as long as you are using SIMATIC software).Setting the PROFIBUS addressWhen your instrument is shipped, the PROFIBUS address is set to 126. You can set it locally (see Setting the PROFIBUS address via the handheld programmer on page 27) or remotely via the bus, using a parameterization tool such as SIMATIC PDM (see Address (default 126) on page 58).PROFIBUS addressBus TerminationPower DemandsTo determine how many devices can be connected to a bus line, calculate the combined maximum current consumption of all the connected devices: 10.5 mA for SITRANS LR 200. Allow a current reserve for safety. 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.Note: If you are not using SIMATIC software, you can download the GSD file separately, and import it with the software you are using.Values Range: 0 to 126Pre-set: 126Note: PROFIBUS PA MUST be terminated at both extreme ends of the cable for it to work properly. Please refer to the PROFIBUS PA User and Installation Guidelines (order number 2.092), available from www.profibus.com.
Page III-48 SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL 7ML19985JM01mmmmmPA: Remote OperationCyclic DataWhen you configure SITRANS LR 460 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, Distance, or Volume. Within the function blocks, the values are scaled according to the user requirements (see Analog Input Function Blocks 1 and 2 on page 55 for details).AIFB1 and AIFB2 return 5 bytes of data each:The first 4 bytes are the floating point representation (IEEE) of the variable. 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 PD Slave.Status ByteNote: Each of the slots has to have a module defined in it. 1.

The Master will then send a Diagnosis request. The reply to this request is normally logged in the PLC and is referred to as the "Hex values."The reply may contain two parts. The first part is 6 bytes long and is defined by the PROFIBUS standard. If there is a second part, it is called the ’extended diagnostic’ and it is eight bytes long.

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 and volume 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 Failsafe 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
7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 53mmmmmProfile structureDescription of the blocksTransducer block function groupsThe figure below shows the signal flow of measured values from the sensor through the Transducer block into the output value (Primary Value/ Level or Volume; Secondary Value 1 / Level; Secondary Value 2 /Distance 1; or Secondary Value 3 / Distance 2). The Level TB implements all of the basic parameters (see parameter diagram on page 54), including level to volume calculation, if that option has been selected.How the LTB works:1. The sensor technology block selects the proper echo. For an explanation of sensor technology, please refer to Appendix B: Technical Reference, page 82 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 level value is used for volume calculation, if that function is enabled.13. Then linearization can be carried out to accommodate complex tank shapes, or to provide level to volume conversion.4. The LTB provides four possible outputs• Primary Value (PV) / Level or Volume• Secondary Value 1 (SV1) / Level• Secondary Value 2 (SV2) / Distance1 (sensor units)or • Secondary Value 3 (SV3) / Distance 2 (any level units, except %)1.

7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 55mmmmmProfile structureElectronics 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. If a temperature limit is exceeded, the status changes. 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)21. Open View menu, scroll down to Peak Values, and click on Temperature tab in the Peak Values window.2. The output from the Level Transducer Block can be called the Primary Value (or Secondary Value).

Page 56 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01mmmmmProfi;e structureHow 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.Failsafe• If 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.Device / Output SimulationOne of three settings can be selected: • The result is the output parameter (OUT).AIFB execution steps:The AIFBs can provide a linear conversion to any desired units.1. 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.Setting description Output valueAUTO automatic the automatically-recorded measured valueMAN manual a manually-set fixed simulation valueO/S function block disabled the preset safety value.

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 Failsafe condition occurs. The output is determined by the Failsafe 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.

7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 82mmmmmF: Technical ReferenceAppendix B: Technical ReferencePrinciples of Operation SITRANS LR 460 is a long range FMCW (Frequency Modulated Continuous Wave) radar transmitter. Radar level measurement uses the time of flight principle to determine distance to a material surface. The transmit time is directly proportional to the distance to the material. FMCW radar transmits a continuous wave. The frequency of the wave is constantly increasing: this is known as the sweep. By the time the first part of the wave has been reflected off the target and returned to the device, the part of the wave that is just being emitted is at a higher frequency. The difference in frequency between the transmitted and received signals is proportional to time of flight. Electromagnetic wave propagation is virtually unaffected by temperature or pressure changes, or by changes in the vapor or dust levels inside a vessel.SITRANS LR 460 consists of an enclosed electronic component coupled to an antenna and process connection. The electronic component generates an electromagnetic signal from 24.2 GHz to 25.2 GHz that is directed to the antenna.The signal is emitted from the antenna, 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 and output.Measurement ResponseThe measurement response (response rate) 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.If none of the preset options is satisfactory, the filters can be adjusted individually.Related ParametersResponseRateLOE Timer (minutes) Fill Rate Empty RateEcho LockValues1* slow 100 0.1 m/minute 0.1 m/minute2material agitator2medium 10 1 m/minute 1 m/minute3fast 1 10 m/minute 10 m/minute
Page 83 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01mmmmmF: Technical ReferenceEcho LockWhen the echoes are received, the relevant echo algorithm is applied to determine the true material echo. If the selected echo is within the window, the window is then centered about the echo. Otherwise the window widens with each successive shot until the selected echo is within the window, which then returns to its normal width.Echo Lock selects the measurement verification process:• When Echo Lock is Off, SITRANS LR 460 responds immediately to a new measurement (within the restrictions set by the Maximum Fill / Empty Rate). However, measurement reliability is affected. • When Maximum Verification or Material Agitator is selected, a new measurement outside the Echo Lock Window must meet the sampling criteria. • When Total Lock is selected, Echo Lock Window is pre-set to 0, and the window is automatically calculated after each measurement. 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. The LOE timer starts running, and if the LOE condition persists beyond ten minutes (the time limit set by the LOE timer) the Unreliable Echo indicator replaces the Reliable Echo indicator.Reliable Echo indicator Unreliable Echo indicator .While LOE is pending the x flashes, alternating with the two horizontal bars. When LOE becomes active, the x becomes solid and the auxiliary display shows fault code S: 0.Upon receiving a reliable echo, the loss of echo condition is aborted, the Reliable Echo indicator reappears, and the reading returns to the current level.Values0Off1Maximum Verification2*Material Agitator3Tot al L ock
7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 84mmmmmF: Technical ReferenceLOE TimerThe LOE timer determines the time (in minutes) to elapse after the last valid reading before Failsafe mode is activated. When the LOE timer expires, the material level to be reported is determined by Failsafe Mode.Failsafe ModeFailsafe mode may be triggered by a loss of echo, a bad configuration, or certain device faults. You can select can select one of three possible values to be reported when a Failsafe mode occurs:• Default value (Failsafe value) used as output value.• Store last valid output value.• Calculated output value is incorrect.Failsafe valueFailsafe value is a user-defined value. This allows you to enter the safest output value for your application. For example, you may want to select a user-defined high value, to prevent an overfill (Failsafe Hi). Or you may want to select a low value, to protect a pump from operating dry (Failsafe Lo).False EchoesFalse echoes can appear during the receive cycle. They are often created by internal impediments like a ladder rung, and are usually indicated by an incorrect high level reading. Near Range (Blanking)Near Range allows you to set a distance in front of the antenna, within which any echoes will be ignored. But Auto False-Echo Suppression is generally recommended in preference to using Near Range.Auto False-Echo SuppressionThe TVT adjustment parameters allow you to set a TVT (Time Varying Threshold) curve, so that SITRANS LR 460 will ignore false echoes.The default TVT curve hovers above the echo profile, and effectively screens out small false echoes. But if an obstruction is causing a large echo before the material level echo, that echo will rise above the default TVT curve. You can use Auto False-Echo Suppression to filter it out. If possible, rotate the instrument before using Auto False-Echo Suppression, to lower the amplitude of false echoes.
Page 85 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01mmmmmF: Technical ReferenceWhen you set Auto False-Echo Suppression to Learn, the instrument learns the echo profile at that moment1. Then it uses the learned profile instead of the default TVT curve, for the distance set in Auto False Echo Suppression Distance. The learned profile (learned TVT curve) follows the echo profile, so that no large false echoes rise above the learned TVT curve. From the end of the Auto False-Echo Suppression Distance, the default TVT curve is used. The material level echo rises above this, and is selected as the true echo.See page 69 for examples of the echo profile before and after using Auto False-Echo Suppression.1. Set Auto False-Echo Suppression to Learn when the material level is substantially lower than process full level (ideally when the tank is empty or almost empty).
