Page 2 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 SITRANS LR 400 The SITRANS LR 400 is a long-range FMCW radar level instrument. A liquids version (L) is available for use in liquids storage, performing well on low dielectric liquids or sticky materials requiring a purging unit. A solids version (S) incorporates the Easy Aimer design for use in solids, especially conditions of extreme dust. On both versions, the narrow antenna beam results in a sharp radiation cone, which makes the SITRANS LR 400 quite insensitive to vessel interferences.

Then, the unit is ready for programming when the multi-display appears. Note: Frequent switching off and on of the device causes aging of the electronics (see Parameter 3.1). Multi-display The multi-display shows on the LCD after a successful self-test with the output of the level in the first line and the signal-to-noise ratio in the second line (factory setting): + 1 2 . 3 0 0 + 3 0 d b Local Programming When the multi-display appears on the LCD, begin local programming using the hand programmer. To access the parameter settings, press LEFT once. Main Menu is displayed in the first line of the LCD. Then program the unit beginning with the Auto-Setup parameters. Updated graphic required Auto-Setup After switching on the SITRANS LR 400, and after a successful self test, press LEFT to access the parameters. Set the Auto-Setup parameters to make the system operational: (see page 33) • • • • • • • • • The language of the local user interface The unit of length of the measured level The nozzle height in the selected unit of length The vessel height in the selected unit of length The LRV as a distance from the bottom of the vessel The URV as a distance from the bottom of the vessel The damping of the measured level in sec The application type The bus-address by PROFIBUS PA communication (on PROFIBUS models) Enter the necessary values as described in Parameters on page 33.

Refer to the Parameter section that begins on page 32 for a list of available parameters. Page 22 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 Operation General Information You can operate the SITRANS LR 400 with: • • • Hand-held infrared programmer HART Communicator or PROFIBUS PA PC/Laptop and SIMATIC PDM software (recommended) Notes: • The SITRANS LR 400 operates according to the FMCW (Frequency Modulated Continuous Wave) method. Its antenna sends microwaves to the surface of the measuring medium. The wave frequency is modulated continuously (see Determining the Differential Frequency on page 25). A receiver registers the reflection at the surface of the measuring medium and links it with the simultaneously radiated signal. SI TRAN SLR 40 0 The propagation speed of microwaves in gases corresponds to the speed of light. The distance d is proportional to the propagation time t: c⋅t d = -------2 d= distance, t = measured time, c = speed of light 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 24 mmmmm Measuring Principle Operation • The SITRANS LR 400 can be operated and programmed most comfortably with the SIMATIC PDM software. This software gives you the added possibility of saving and archiving your application-specific parameters and copying them back into the device if necessary. It is best to perform the operations described in the following sections directly on the device to familiarize yourself with the operation. As the transmission signal has changed its frequency until the reception signal arrives, the linked signal gives a differential frequency fd, which is proportional to the distance d from the reflecting surface. The distance d is given by the ratio of the differential frequency fd to the frequency deviation B and the duration of a frequency modulation phase T : fd ⋅ T ⋅ c 2⋅B⋅d f d = ------------------, d = ------------------T⋅c 2B B = bandwidth (frequency deviation), d = distance, T = modulation duration, c = speed of light Operation mmmmm Determining the Differential Frequency frequency transmission reception signal signal fd time Example The linear frequency deviation is 200 MHz at a modulation duration of 10 ms. The surface of the measuring medium is 10 m away from the transmitting antenna. The difference signal then has a frequency of: 2 ⋅ 2 ⋅ 10 8 ⋅ 10 - = 13, 333kHz f d = --------------------------------10 – 3 ⋅ 3 ⋅ 10 8 Every reflection at a surface generates a different frequency. The reception signal therefore consists of a frequency mix from which the disturbance frequencies must be filtered. These can be caused by fixed targets like struts inside the vessel. Page 25 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 Operating the SITRANS LR 400 Use the arrow keys at the bottom of the hand programmer to program the SITRANS LR 400. The two-line LCD displays the parameters. You can alter the setting or change to other parameters using the arrows on the hand programmer (see page 27 for information on navigating the menus using the arrow keys). Hand Programmer Note: The ARROW buttons shown below are required for programming this product. The additional buttons on the hand programmer do not apply to the SITRANS LR 400. Parameter scroll UP Parameter scroll DOWN LEFT Arrow (or CANCEL) RIGHT Arrow (or Enter) SITRANS LR 400 buttons Selecting a Parameter After a successful self-test, the SITRANS LR 400 displays the two-line multi-display. Press LEFT ARROW to access the parameter menus. The first line of the display tells you the current parameter menu level. The second line shows one of the parameters you can access in the current parameter group. Scroll through the parameters in the group by touching UP and DOWN . RIGHT accesses the parameter displayed on the second line. LEFT closes this parameter and moves up one level until you return to the multi-display. When you select a parameter, its current value is displayed in the second line. When the value flashes, programming is enabled, (see Disabling and Enabling Programming on page 29) and you can change the current setting. If the parameter value cannot be changed or if programming is disabled, the value will not flash. Note: The background illumination of the LCD switches on as soon as you use a button. It goes out about three minutes after last use of programming button. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 26 mmmmm Programming Mode Operation Key Structure of Parameters Operation is hierarchically structured: the parameters are arranged in groups and assigned a numerical menu identification (see example below). 2.

You will see a single item of the selection list in the second line of the display. • Press UP or DOWN to cycle through the list and choose the desired entry. Press RIGHT to assign the current entry to the parameter. The device accepts the new setting, closes the input and returns to the next parameter level up. • LEFT operates like a CANCEL key: When pressed, the device closes the parameter input but keeps the originally displayed value. It does not save a changed setting! For an example of assigning a value from a selection list, see Operating Examples on page 30. Page 27 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 Entering a Parameter Value The ARROW keys operate like a cursor control when entering a parameter value with the input position marked by flashing of a single character. • • • Increase or decrease a character’s value by using UP and DOWN . Press RIGHT to move the input position to the right. At the far right position, press RIGHT again: operates like an ENTER key. The device saves the changed value and closes the parameter unless the value is not within the permissible input range. Then an error message is displayed. Press LEFT to move the input position to the left. At the farthest left position, press LEFT again: it now functions as a CANCEL key. The device closes the parameter input without saving the changed value. This input system also works in the opposite direction: For example, when 100 is displayed and you press DOWN on the first or second 0, the numeric value changes to 90 or 99 and the device cancels the places in front of the decimal point. Decimal point You can also set the cursor to the decimal point (unless an integer value is currently displayed). UP or DOWN then multiply or divide the displayed value by 10. The necessary additional places in front of the decimal point appear. You cannot change the number of displayed decimal places. Display scrolling Display text assigned to a parameter may sometimes be longer than the field of the display. An arrow pointing outward on the right or left hand side of the display line indicates that the text continues outside the display. You can move the text with RIGHT and LEFT by moving the pointer past the end of the line, to allow you to read the rest of the text. See Operating Examples on page 30 for an example of manual input. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 28 mmmmm If you press UP when the value is at the top of the representable range, SITRANS LR 400 automatically places the value at the next highest position. If 0.9 is displayed and you press UP , the value becomes 1.0. So, 9 becomes 10, 90 or 99 become 100 (depending on whether you have set the input position to the second or first 9), etc. Operation Top or bottom of representable range Disabling and Enabling Programming To prevent unauthorized personnel causing programming errors through the display module, set a customer code – a personal, freely selectable code number up to 9 digits. A device protected by a customer code still displays all functions and values but it requests input of the code number before allowing a parameter to be reset. Note: The customer code is activated 10 minutes after you have programmed Parameter 5.2 Customer Code. Programming is enabled when you: Operation mmmmm • enter the requested customer code for the current parameter. (Only the current parameter is enabled for reprogramming. All the others are still waiting for input of the customer code.) or • release the programming lock for all parameters at once using the Code Input Parameter (see Parameter 5.1 on page 62). The programming lock will be released for approximately 10 minutes. When you return to the multi-display or enter a number in the Code Input parameter which is different from the customer code, or do not operate the device for 10 minutes, the programming lock is enabled. Note: If Customer Code (Parameter 5.2) is 0, programming of parameters is always enabled. We strongly recommend that a customer code be entered after all programming is completed to secure the programmed values from change.

However, the parameters that remain under 4.2.2.x will be renumbered. See page 32 for more information on parameter renumbering. 4.2.2.2: Surface (F = wavy) Surface structure of the measuring medium. Not displayed if a user vessel is selected in Parameter 4.2.2.1. Value Smooth Wavy Turbulent This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1. When used with poorly reflecting measuring media, you may be able to improve measuring results by setting a different surface structure here. If your measuring medium forms waves more than 1 cm in height, you should select the wavy setting. The turbulent setting is recommended for waves greater than 10 cm. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 42 mmmmm Note: The following parameters cannot be accessed when you set a user vessel: Parameters (HART) Select Silo1 (solids) for tall, narrow silos. Select Silo 2 (solids) for large diameter silos typically used for cement. In most cases you set one of the pre-specified applications here. The user vessels may adopt configurations which deviate from the factory settings. These are designed for special applications loaded at the factory or by service. 4.2.2.3: Dead band (F = 0.4 m) Area below the flange in which measured values are ignored Value numerical value, Minimum value = Length of the antenna Specification of a dead band in the units system selected according to Parameter 4.1.5 defines a minimum distance from the flange which the measuring medium must have for the device to accept the measured values as valid. This suppresses reflective interference generated by the nozzle, close obstacles, or the antenna. For solids applications, a dead band setting of 1 m minimum is recommended Note: The dead band should exceed the antenna’s length. 4.2.2.4: Correction Factor (F = 1.0) Correction factor for physical measuring influences Parameters (HART) mmmmm Value numerical value The propagation time of the microwaves between the antenna and the measuring medium changes slightly depending on the pressure inside the vessel. If this pressure is constant, however, it can be included in the evaluation according to the equation: K = ------------------------------------------------------------------------273 ⋅ p 1 + ( ε r, Gas – 1 ) ⋅ -------------------------T Gas + 273 K = correction factor, p = pressure inside the vessel in bar, Tgas = gas temperature in °C, εr, Gas = dielectric of the overlying gas, e.g. ερ, air = 1.00059 Enter the correction factor K as a dimensionless value. 4.2.2.5: Filling Speed (F = 200 mm/min) Typical speed of change of the level. Not displayed if user vessel is selected in Parameter 4.2.2.1 (Application Type). Value numerical value This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1. When you determine that the displayed measured value does not follow the change in the height of the level in the vessel, you can enter a value for the speed with which it generally changes. This assigns a greater probability to measuring targets which move at this speed. Page 43 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 If the display does not follow the level height continuously but in abrupt jumps, you should choose a higher filling speed. If multiple echoes are indicated during filling/emptying a vessel, select a lower filling speed. In the case of very low filling speeds (a few mm/min) switch off Parameter 4.2.3.3. If different filling/emptying speeds occur, select the higher speed. 4.2.2.6: Reflectivity (for qualified personnel only) This parameter is for Factory Authorized Personnel Only. 4.2.2.7: Failsafe Level (F = Hold Continuously) Selects the default measurement in the event that the failsafe timer expires Value 100 % 0% Hold Continuously 4.2.2.8: Failsafe Timer (F = 10 min) Sets the time delay, in minutes, before entering failsafe level 1 min 2 min, etc. 4.2.2.9: Range Extension (F = 3 m) Sets the amount of range extension as measured from the tank height and extending beyond the measurement range. For vessels with conical or parabolic bottoms, you may need to increase this value to ensure an empty vessel reads empty. Value numerical 4.2.3: Sensor Parameter Here you can view and change the sensor parameters which you have selected according to Parameter 4.2.2 (Measuring Conditions). Note: The factory settings for the user vessels are not editable. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 44 mmmmm The failsafe timer begins when there is a loss of echo condition. This loss of echo condition will occur when there is no signal available above the Auto False Echo Suppression threshold as defined in Parameter 4.2.3.9. Parameters (HART) Value 4.2.3.1: Sensor Damping (F = 1 s) Averaging of measuring signal. Not displayed if a user vessel is selected in Parameter 4.2.2.1 (Application Type). Value numerical Enter the damping in seconds. This parameter is not displayed when a user vessel is selected in Parameter 4.2.2.1 (Application Type). The sensor damping influences the evaluation of the measuring signal. If the level generally only changes slowly and continuously, a time constant set here can improve the measuring accuracy and the validity in poorly reflecting measuring media or those with a restless surface. The sensor damping must always be smaller than the interval of the time of change of the level (e.g. 1 mm/10 s), because too high a value would have a negative influence on the measuring result. Note: Specification of damping directly influences the evaluation of the measuring Parameters (HART) mmmmm signal. If you only want to dampen the calculated outputs at the analog output, you should set the damping of level, volume or mass described in Function 4.2.4.4 (MinLim Level). 4.2.3.2: Multiple Echo (F = on) Evaluate multiple echo On Off Value The multiple echo evaluation suppresses multiple reflections by assigning them a lower probability than the measuring signal. 4.2.3.3: Echo Motion (F = off) Evaluate echo motion Value On Off Dynamic processes in the vessel are included in the evaluation of the measuring targets. The typical filling speed can be set in Parameter 4.2.2.5. If the measured value still does not follow the level height, switching off echo motion may improve the result. Page 45 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 4.2.3.4: Window Tracking (F = Off) Value On Off A window follows the measured value which it is forced to track. The window size is calculated from the set filling speed. Switch off window tracking for applications where the SITRANS LR 400 is unable to keep up to level changes. By using SIMATIC PDM, you can display a list of all echoes in your vessel. It provides the distance between the flange and the measuring medium’s surface, as well as the distances of fixed targets. These may be directly used and transferred to the fix distance list. 4.2.3.5: Tank Empty Detect (for qualified personnel only) This parameter is for Factory Authorized Personnel Only. 4.2.3.6: Auto Fix Distance (for qualified personnel only) This parameter is for Factory Authorized Personnel Only. 4.2.3.7: Fix Distance List (for qualified personnel only) These parameters are for Factory Authorized Personnel Only 4.2.3.8: Auto False Echo Suppression (F = Use) Learns and records the current signal up to the suppression distance setting. These signals are then ignored during operation. Note: This function works best when the vessel is nearly empty. For best results, do not record or learn when the vessel is completely empty. Value Off Record Use If all signals fall below this defined threshold, then the failsafe timer is initiated. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 46 mmmmm 4.2.3.7.1 to 4.2.3.7.9: Fix Distance Values (for qualified personnel only) Parameters (HART) This parameter is for Factory Authorized Personnel Only. 4.2.3.9: Auto False Echo Suppression Distance (F = 2/3 tank height) Defines the end point of the auto false echo suppression distance Value variable 4.2.3.A: Hover Level (F = 40%) Defines (in percent) how high the TVT (Time Varying Threshold) curve is placed above the profile, relative to the largest echo.

It corresponds to an output current of 20 mA. Note: This parameter is also set using Parameter 1.5 (Level URV). 4.2.4.2: Level LRV (F = 0 m) Empty scale of level (see Functional Dimensions on page 33) Value numerical value Set the LRV as the level above the bottom of the vessel (see Functional Dimensions on page 33) in the units system selected with Parameter 4.1.1. It corresponds to an output current of 4 mA. Note: This parameter is also set using Parameter 1.6 (Level LRV). Page 47 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 4.2.4.3: Level damping (F = 1 s) Damping of level in s Value numerical value Set the damping of the level value in seconds.

The selection controls the display of Parameter 4.2.5.8. The possibilities of each parameter are listed below. For the values associated with Parameter 4.2.5.8: Calculate, go to page 51. 4.2.5.8: Calibrate/table If your vessel deviates from the forms offered, the necessary data is not available or is unknown, or you need a vessel characteristic with greater accuracy, you will need to use a level/volume calibration table. You can enter reference values from a table provided by the vessel manufacturer or do the calibration manually and enter the determined reference values. You can only enter pairs of values consisting of level and volume. Note: Entering the vessel characteristic with the hand programmer can be a timeconsuming procedure. It can be done more quickly and comfortably with the SIMATIC PDM software. There, an entered table can be edited simply – an option which is only conditionally possible with the hand programmer. The 4.2.5.8 Calibrate/table parameter offers the following selection possibilities: If you access this parameter, first the currently measured level is displayed. Accept it by pressing LEFT . Enter the appropriate volume: save it by pressing RIGHT or reject it by pressing LEFT Then the device displays Calibrate. Access again by pressing RIGHT to select a further reference value. The device automatically offers you the next undefined reference value. We recommend entering a maximum of two or three reference values for the linear range of the vessel and to use the others for the non-linear portion. If you enter a second volume value for the same level, the reference value saved earlier is overwritten. 4.2.5.8.2: Enter table Manual entry of a table Value numerical value Here you can enter up to 50 reference values provided by the vessel manufacturer in any order. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 50 mmmmm Here you can enter up to 50 reference values whose levels SITRANS LR 400 measures. Enter the appropriate volume (determined by manual calibration). Parameters (HART) 4.2.5.8.1: Calibrate The first reference value is offered when you access the parameter. Enter the level as a distance from the floor of the vessel in the units selected according to Parameter 4.1.1 (Enter level) and the volume corresponding to the level (Enter volume). The device then displays Enter table again. Access again to enter a further reference value. The device automatically offers you the next undefined reference value. We recommend entering a maximum of two or three reference values for the linear range of the vessel. Use the other reference values for the non-linear section. If you enter a second volume value for the same level, the reference value saved earlier is overwritten. 4.2.5.8.3: Show table Display table Value selection Parameters (HART) mmmmm Here you can display the entered reference values sorted on levels. In the second line, the level corresponding to the first reference value appears first and then the corresponding volume value when you switch further. Each switching accesses a further reference value. 4.2.5.8.4: Clear table Delete table Value selection If you choose all in this parameter, the entire saved table is deleted. You can delete individual reference values with the selection 1st, 2nd etc. that were displayed in Parameter 4.2.5.8.3. Note: The reference values are sorted in order of filling states and do not necessarily correspond to the order of the value pairs you have entered. or 4.2.5.8: Calculate Automatic calculation of a vessel characteristic is faster than manual entry by calibrating or a table. However, the calculated vessel characteristic is not as accurate as a manually calibrated characteristic – especially in the non-linear sections of the vessel when errors of ≤ 1 % may occur. As well, the necessary data which you can get from the design documents of your vessel must still correspond to the real conditions. The 4.2.5.8: Calculate parameter requires the following parameters: Page 51 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 4.2.5.8.1: Tank Design (F = Vertical Cylinder) Value Linear Vertical cylinder Horizontal cylinder Sphere Enter the external form of your vessel.

WARNINGS: • Materials of construction are chosen based on their chemical compatibility (or inertness) for general purposes. For exposure to specific environments, check with chemical compatibility charts before installing. • The user is responsible for the selection of bolting and gasket materials which will fall within the limits of the flange and its intended use and which are suitable for the service conditions. • Never attempt to loosen, remove, or disassemble process connection or instrument housing with vessel contents. • Improper installation may result in loss of process pressure. Page 91 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 Appendix V The SITRANS LR 400 can be configured over the HART network using either the HART Communicator 275 by Fisher-Rosemount, or a software package. There are a number of different software packages available, and the SITRANS LR 400 should work well with any of them. The recommended software package is the SIMATIC® Process Device Manager (PDM) by Siemens. HART Device Descriptor (DD) In order to configure a HART device, the configurator must have the HART Device Descriptor for the unit in question. HART DDs are controlled by the HART Communications Foundation. The HART DD for the SITRANS LR 400 is available on the SITRANS LR 400 page of our website at www.siemens.com/milltronics. Older versions of the library will have to be updated in order to use all the features in the SITRANS LR 400. If you do not see SITRANS LR 400 under Siemens Milltronics using the configurator, you will need to download an update file from our website: www.siemens.com/milltronics SIMATIC Process Device Manager (PDM): This software package is designed to permit easy configuration, monitoring and troubleshooting of HART and PROFIBUS PA devices. The HART DD for the SITRANS LR 400 was written with SIMATIC PDM in mind and has been extensively tested with this software. The HART DD for the SITRANS LR 400 is available on the SITRANS LR 400 page of our website at www.siemens.com/milltronics. 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 92 mmmmm Highway Addressable Remote Transducer, HART, is an industrial protocol that rides on top of a 4-20 mA signal.

Page 97 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 Appendix VI PROFIBUS PA Communications for the SITRANS LR 400 PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be obtained from PROFIBUS International at www.profibus.com The SITRANS LR 400 is a Class A, Profile Version 3.0, PA device. It supports Class 1 Master for Cyclic data exchange, and Class 2 for acyclic services: (See below for details). In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the Device Descriptor, which will be included with new versions of PDM. Currently you can locate the Device Descriptor in Device Catalog, under Level/Echo/Siemens Milltronics. If you do not see SITRANS LR 400 under Siemens Milltronics, you will need to download an update file from the SITRANS LR 400 product page on our website: www.siemens.com/milltronics The GSD file The GSD file SM_062A.GSD can be obtained from Siemens Milltronics at our web site: www.siemens.com/milltronics. (There is an example on page 102, To configure and use PROFIBUS PA with an S7-300 PLC.) Bus address (Device Address) Values • Range: 0 to 126 Pre-set: 126 This value can be set via Bus Address in the Auto-setup parameters, or over the network. (After changing the value, turn the unit off and back on again in order for the change to take effect.) 7ML19985FH04 SITRANS LR 400 – INSTRUCTION MANUAL Page 98 mmmmm Device Descriptor Appendix VI The SITRANS LR 400 can be configured using a software package. There are a number of different software packages available and the SITRANS LR 400 should work well with any one of them. The recommended software package is the Simatic Process Device Manager (PDM) by Siemens. Power Demands The maximum number of devices that can be connected to a bus line depends on their current consumption and the respective application conditions. When operating in an area where there is no risk of explosion, the couplers/links can feed up to 400 mA into the bus. When operating in explosion risk areas, the intrinsic safety is only guaranteed when the maximum power fed into the bus does not exceed certain voltage and current values. These are normally: Appendix VI mmmmm Current IS < 128 mA, voltage U0 < 15 V WARNING: Only certified supply units (DP/PA couplers or DP/PA links) may be used to feed the intrinsically safe PROFIBUS. See the EC Type Examination Certificate for requirements. The number of devices which can be connected to a bus line is determined by finding the combined maximum current consumption of all the connected devices (10.5 mA for the SITRANS LR 400). Plan to 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 and output 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 Data When you configure the SITRANS LR 400 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. Slot 0 always transmits Level information and slot 1always Volume information. Slot2 is always Mass information. If you do not wish to have data transmitted, then you must use a Free Place module in that slot. When you select a module, for the three values, there are two alternatives: a normal version and a short version, for example, Level (short) and Level. The difference between the two is the way each one identifies the function block used. Level uses both the identifier and the extended identifier byte to determine which function block in the unit to use. Level (short) uses only the identifier byte. In the current release of PROFIBUS PA there is no functional difference between the short and normal versions. However, the longer identifier is the preferred way to identify the function block and you should select the normal version in each case. Page 99 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH04 The 3 function blocks (Level, Volume, Mass) return 5 bytes of data each: Floating Point Status Level byte 1 byte 2 byte 3 byte 4 byte 5 Volume byte 6 byte 7 byte 8 byte 9 byte10 Mass byte 11 byte 12 byte 13 byte 14 byte 15 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. If you select a Free Place module to fill one of the slots, this will affect the byte number. Example 1: Floating Point Free Place Status — — — — — Volume byte 1 byte 2 byte 3 byte 4 byte 5 Mass byte 6 byte 7 byte 8 byte 9 byte 10 Example 2: Floating Point Level byte1 Free Place Mass 7ML19985FH04 Status byte 2 byte 3 byte 4 byte 5 — — — — — byte 6 byte 7 byte 8 byte 9 byte 10 SITRANS LR 400 – INSTRUCTION MANUAL Page 100 mmmmm The 5th byte is the status word and the list of possible values is given in the chart on page 101. Appendix VI The first 4 bytes are the floating point representation (IEEE) of the variable. The variables are the outputs of the function block. The default setting for the variable level is meters. The default setting for the variable volume is m3. The default setting for the variable mass is kg. You can change the settings of the variables by changing the settings of the function block. This is typically done using PDM.
