Remote operation via PROFIBUS PA SITRANS LR 460 is a Class B, Profile Version 3.0, PA device. 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.
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.
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.

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.
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.
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 4 3.5 3 Level Value 2.5 2 1.5 Low Level Point 1 0.
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.
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.
2. The scaling output is applied. For example: Process Variable range (typical Input (0 to 100%) AIFB2 3. 4. 5. 6. Out (or AIFB2 Out) 5 4 3 2 straight to LCD (same values displayed on LCD as PLC) 1 0 1 2 3 4 5 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.

mmmmm Parameters Page 81 SITRANS LR 460 – INSTRUCTION MANUAL 7ML19985JM01
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.
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.
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.
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.
