It supports Class 1 Master for cyclic and acyclic data exchange, and Class 2 for acyclic services. The full range of SITRANS LR 460 functions is available only over a PROFIBUS PA network. PA: Remote Operation mmmmm PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be obtained from PROFIBUS International at www.profibus.com. To use PROFIBUS PA, you will need a PC configuration tool: we recommend SIMATIC PDM. Please consult the operating instructions or online help for details on using SIMATIC PDM. (You can find more information at www.fielddevices.com: go to Products and Solutions > Products and Systems > Process Device Manager.) SIMATIC PDM SIMATIC PDM is a software package for designing, parameterizing, commissioning, diagnosing and maintaining SITRANS LR 460 and other process devices. SIMATIC PDM contains a simple process monitor of the process values, alarms and status signals of the device. Using SIMATIC PDM you can • display • set • change • compare • check the plausibility of • manage • simulate process device data. Device Description In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the Device Description for SITRANS LR 200, which will be included with new versions of PDM. You can locate the Device Description in Device Catalog, under Sensors/Level/ Echo/Siemens Milltronics. If you do not see SITRANS LR 460 under Siemens Milltronics, you can download it from our web site. Go to the SITRANS LR 460 product page at https:/ /pia.khe.siemens.com/index.asp?Nr=7427 and click Downloads. After downloading the DD file, you need to execute DeviceInstall. Page III-46 SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL 7ML19985JM01 Configuration To configure a PROFIBUS PA Class 1 Master (for example, a PLC), you will need a GSD file. The GSD file The GSD file SIEM810F.gsd is available from the SITRANS LR 460 product page on our web site. Go to https://pia.khe.siemens.com/index.asp?Nr=7427 and click Downloads. Download the DeviceInstall, and run it from your computer. This will install the GSD file into your system (as long as you are using SIMATIC software). separately, and import it with the software you are using. When 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 address Values Range: 0 to 126 Pre-set: 126 Bus Termination Note: 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. Power Demands To 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 Data When 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. 7ML19985JM01 SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL Page III-47 mmmmm Setting the PROFIBUS address PA: Remote Operation Note: If you are not using SIMATIC software, you can download the GSD file Cyclic Data When you configure SITRANS LR 460 on the PROFIBUS PA bus, there are two slots available for modules. Note: Each of the slots has to have a module defined in it. PA: Remote Operation mmmmm 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: Floating Point Status AIFB1 byte 1 byte 2 byte 3 byte 4 byte 5 AIFB2 byte 6 byte 7 byte 8 byte 9 byte10 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 Byte Status Codes for Good Quality Values in hex notation Description 0x80 Data is GOOD. 0x84 A parameter in the function block has been changed: status active for 10 s 0x89 Active low warning. 0x8A Active high warning. 0x8D Active low alarm. 0x8E Active high alarm. 1.

During DPV0 data exchange, the PROFIBUS PA slave will notify the Master when a serious error occurs. 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. The last four bytes of the extended diagnostic message give the error code shown below. (The same information is also available acyclically via the Diagnosis Object. 7ML19985JM01 SITRANS LR 460 (PROFIBUS PA) – INSTRUCTION MANUAL Page III-49 mmmmm This could happen when a firmware download has been done, but a system reset has not been done.

PROFIBUS PA Profile Structure PROFIBUS Level Device Design The device follows the profile block model and is implemented as a Profile 3.0, Class B, PA device. Standard profile parameters are used to program the level transducer block. Block Model for recording and processing measured values The functions of the device are divided into blocks for different areas of responsibility. They can be parameterized by acyclic data transfer via PDM. sensor Profi;e structure mmmmm sensor Transducer Block Analog Input Function Block1 Analog Input Function Block2 PROFIBUS PA electronics temperature 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 AIFB2 The 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. Page 52 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01 Description of the blocks Transducer block function groups The 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. Level Transducer Block Level Sensor Value Sensor Sensor technology Level calibration Sensor Offset Linearization Linearization Type PV SV1 Secondary Value 1 [Level] (Level Units) SV2 AIFB1 (Analog Input) AIFB2 (Analog Input) Sensor Level unit conversion SV3 Secondary Value 2 [Distance 2] (Level Units) 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. 7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 53 mmmmm Secondary Value 2 [Distance 1] (Sensor Units) Profile structure Level Offset Low High Calibration Calibration Point Point High Level Low Level Point Point Calibration Type Primary Value [Level/Volume] (level/volume units) 2. Level Calibration is a linear transfer function that converts a sensor value to a level value. The level value is used for volume calculation, if that function is enabled.1 Level 4.5 High Level Point 3.5 Level Value 2.5 1.5 Low Level Point 0.5 Calibration Low Calibration Point Sensor Value High Calibration Point Sensor Reference Point (flange face) (distance 1 or 2) SV2 or SV3 High Calibration Point Sensor Value Level Profi;e structure mmmmm High Level Point (default: 100%) Sensor Offset Low Level Point (default: 0%) Low Calibration Point Level Offset1 Secondary Value 1 3. 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 • • • • 1. Page 54 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 %) Level Offset (default O) can compensate for specific tank configurations. SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01 Electronics temperature The 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 2 The 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 Operator Operator Simulate Parameter Out of OUT Service Value FB algorithm Status Failsafe AUTO Alarm OUT Limit Value Status Check MODE and STATUS handling 1. 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). When it becomes the input to the AIFB, it is called the Process Variable. 7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 55 mmmmm simulate value and on Process Variable2 status from LTB (Function Block input) Value Status off Profile structure OUT MAN enable How the AIFBs work The Analog Input Function Blocks allow you to control modifications to the output value (PROFIBUS cyclic data). Output Conversion Values 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 Simulation The 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 Simulation One of three settings can be selected: Profi;e structure mmmmm Setting description Output value AUTO automatic the automatically-recorded measured value MAN manual a manually-set fixed simulation value O/S function block disabled the preset safety value. • 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. Page 56 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01 2.

Out (or AIFB2 Out) straight to LCD (same values displayed on LCD as PLC) Output range: This value is filtered using a first order filter based on a time constant provided by the user. 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. The target mode parameter allows the entire AI block to be overridden by a Manual Out value. 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.) The OUT VALUE parameter is the value for the cyclic data transfer.

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 Response The 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. Related Parameters Response Rate LOE Timer (minutes) Fill Rate Values 1 * slow medium fast 100 10 0.1 m/minute 1 m/minute 10 m/minute Empty Rate 0.1 m/minute 1 m/minute 2 10 m/minute Echo Lock material agitator If none of the preset options is satisfactory, the filters can be adjusted individually. 7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 82 mmmmm Principles of Operation F: Technical Reference Appendix B: Technical Reference F: Technical Reference mmmmm Echo Lock When 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: Values • • • Off Maximum Verification Material Agitator Total Lock 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. Page 83 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01 Failsafe Mode Failsafe 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 value Failsafe 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 Echoes False 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 Suppression The 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. 7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 84 mmmmm The 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. F: Technical Reference LOE Timer F: Technical Reference mmmmm When 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. Page 85 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).

Glossary mmmmm dielectric: a nonconductor of direct electric current.1 dielectric 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 µV rms. Echo Profile: a graphical display of a processed echo. emission cone: the extension of the antenna’s angle false echo: any echo which is not the echo from the desired target. Generally, false echoes are created by vessel obstructions. 1. Many conductive liquids/electrolytes exhibit dielectric properties; the relative dielectric constant of water is 80. Page 95 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01 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. nozzle: 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. polarization 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 transmit time. 7ML19985JM01 SITRANS LR 460 – INSTRUCTION MANUAL Page 96 mmmmm Near Blanking: see Blanking Glossary multiple echoes: secondary echoes that appear as double, triple, or quadruple echoes in the distance from the target echo. 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. Glossary mmmmm 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. stillpipe: a pipe that is mounted inside a vessel parallel to the vessel wall, and is open to the vessel at the bottom. stilling-well: see stillpipe. 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.
