SITRANS LR260
SITRANS LR260 Overview
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring
of solids and liquids in storage vessels including extreme levels of dust and high
temperatures, to a range of 30 m (98.4 ft).
The instrument consists of an electronic component coupled to a horn antenna with an
integral Easy Aimer and flange for quick and easy positioning. A dust cover or air purging
are available as options.
SITRANS LR260 supports PROFIBUS PA communication protocol, and SIMATIC PDM
software. Signals are processed using Process Intelligence which has been field-proven
in over 1, 000,000 applications worldwide (ultrasonic and radar). This device supports
acyclic communications from both a PROFIBUS Class I and Class II master.
Programming
SITRANS LR260 is very easy to install and configure via a graphical local user interface
(LUI). You can modify the built in parameters either locally via the Siemens infrared hand-
held programmer, or from a remote location via SIMATIC PDM.
Applications
• cement powder, plastic powder/pellets, grain, flour, coal, and other applications
• solids and liquids bulk storage vessels
Approvals and Certificates
SITRANS LR260 is available with General Purpose approval, or for Hazardous areas. For

Mounting location
Nozzle design
• The end of the horn must protrude
a minimum of 10 mm (0.4”) to avoid
false echoes being reflected from
the nozzle.
• Optional antenna extensions:
100 mm (3.93"), 200 mm (70.9"),
500 mm (19.69"), 1000 mm (39.4")1)
Nozzle location
• Keep emission cone free of
interference from ladders,
pipes, I-beams or filling
streams.
• Avoid central locations on
tall, narrow vessels.
• Align the antenna so that the
radar cone is perpendicular
to the surface of the
monitored material, if
possible. (See
Easy Aimer
on page 16.)
Notes:
• Correct location is key to a successful application.
• Avoid reflective interference from vessel walls and obstructions by following the
guidelines below
1) Extensions are not recommended for applications where there may be excessive visible
vibration. Please consult the factory for more information.
Notes:
• Beam angle depends on horn size.

1. Holding the electronics enclosure firmly, loosen
the Easy Aimer ball locking bolts and gently
reposition the enclosure.
2. Direct SITRANS LR260 so the horn antenna is
pointed at an angle perpendicular to the
material surface, if possible. (As a guide, aim
the beam at a point approximately 2/3 of the
way across the tank diameter.)
3. When the desired position is reached, re-
tighten the 5 bolts to 15-23 Nm (11 to 17 Lbf-ft).

Installation
Air 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.

Installation
Dust Cap (Optional)
The dust cap fits onto the end of the horn and prevents the buildup of dust and other
process material inside the horn.
• It is particularly useful for applications in areas of high humidity, or with bulk solids
with a high moisture content.
• Three sizes are available, to fit the standard 2", 3", and 4" horns.
Installation
1. Thoroughly clean inside the horn. If you remove the horn for easier cleaning, take
care not to damage or bend the plastic emitter.
2. Press the cap firmly onto the horn until the ridge inside the cap snaps into position in
the groove on the outside of the horn.
3. Hand tighten the adjustable clamp supplied to secure the cap.
4. Use a screwdriver or nut driver to tighten the clamp screw until the clamp provides
an air-tight seal.
1) Universal flange mates with EN 1092-1 (PN16)/ASME B16.5 (150 lb)/JIS 2220 (10K) bolt hole
pattern.
Note: The dust cap must be removed before using the Air Purge feature. (See
Air
Purging System (Optional)
on page 17).
Note: It is critical to ensure no moisture can be trapped inside.

Auto False Echo Suppression
SITRANS LR260 first learns the echo profile. Then the learned profile, or part of it, is used to
screen out false echoes. (See
Auto False Echo Suppression
on page 105 for a more detailed
explanation.)
1. Determine Auto Suppression Range (the distance within which the learned TVT will
replace the default TVT). Measure the actual distance from the antenna reference
point to the material surface using a rope or tape measure, and make allowances
for the actual location of the LR260. Subtract 2 m (6.56 ft) from this distance, and use
the resulting value.
2. Open the menu Device – Auto False Echo Suppression.
3. Enter the value for Auto Suppression Range and click on Set Range.
4. Click on Learn. While the new curve is being learned, all buttons are inaccessible.
Unless calculation is instantaneous, buttons will disappear until it is complete.
5. When the buttons are visible, click on Close. Auto TVT is now on, and the learned
TVT curve will be used.
6. To turn Auto False Echo Suppression off or on, re-open menu Device – Auto False
Echo Suppression and click on Off or On.
Notes:
• If possible, adjust Auto False Echo Suppression parameters with an empty or almost
empty vessel. There should be a minimum distance of 2 meters from the radar
instrument to the material.
• Set Auto False Echo Suppression and Auto Suppression Range during installation, if
possible.
• Before adjusting these parameters, rotate the instrument for best signal (minimum
false-echo amplitude).

Parameters
2.3.1.9.5. Limit Hysteresis
Hysteresis is used to adjust the sensitivity of the trigger for alarm
messages. It is used to compensate when a process variable
fluctuates around the same value as a limit. A high level alarm occurs
when a value exceeds an upper limit. The alarm’s status remains
true until the value drops below the limit minus the alarm hysteresis.
The directions are reversed for low limit detection.

B: Troubleshooting
Appendix B: Troubleshooting
1. Check the following:
• There is power at the instrument.
• The LCD shows the relevant data you are expecting.
• Check whether any fault codes are being displayed (see
Acyclic Extended
Diagnostics (General Fault Codes)
on page 127 for a detailed list).
• The device can be programmed using the hand-held programmer.
2. Verify that the wiring connections are correct.
3. Check the PROFIBUS address and make sure all devices are at unique PROFIBUS
addresses.
4. If the device cannot be programmed via the hand-held programmer, make sure Write
Locking (6.1.) on page 88 is disabled.
5. If you try to set a SITRANS LR260 parameter via remote communications, but the
parameter remains unchanged, check the following parameters:
•Remote Lockout (5.2.) on page 88 should be disabled
•Write Locking (6.1.) on page 88 should be disabled
•Resetting the PROFIBUS address to 126: on page 120 on how to disable an
address lock
6. If you continue to experience problems, go to our website at:
www.siemens.com/processautomation, and check the FAQs for SITRANS LR260, or
contact your Siemens Milltronics representative.
7. If the PLC value equals the display value, but does not correspond to actual material
level, either:
• scaling in AIFB1 is incorrect, or
• High Calibration Point is incorrectly entered, or
• the wrong echo is being selected.
8. If the PLC value is not equal to the displayed value (regardless of actual material
level), either:
• you may not be looking at the right spot in the PLC, or
• you may have programmed scaling into the PLC, instead of leaving all scaling to
be performed in the LR260, or
• the PLC may not be communicating with the LR260. Check the network to verify
that you are communicating.

Appendix D: Technical Reference
Principles 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 Processing
Process Intelligence
The 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 A5E32337685
mmmmm
D: Technical Reference
Higher 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) Curves
A 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 Lock
If 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 Detection
The 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

a low dK value, which may cause the vessel bottom to be reported as the level instead of
the actual material level, in low level conditions. 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 Suppression
If 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 Range
Near Range
2.2.3.5.1. 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).

D: Technical Reference
Far Range
In 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 Response
The 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.
Damping
A 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 (Loss of Echo) Timer
LOE 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 Mode
The 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 value
When 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.

Structure
PROFIBUS Level Device Design
The device follows the profile block model and is implemented as a Profile 3.01, 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.
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 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 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.

F: Profile structure
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 (PV): Level
• Secondary Value 1 (SV1): Level/Volume
• Secondary Value 2 (SV2): Distance
The Level TB implements all of the basic parameters.
How the LTB works
1. 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.

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.

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.
Fail-safe
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.
1) Open the menu View – Peak Values.
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.

Device / Output Simulation
One 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.
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 OUT VALUE parameter is the value for the cyclic data transfer.
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.

Appendix G: Communications via
PROFIBUS PA
SITRANS LR260 (PROFIBUS PA) is a Profile Version 3.01, Class B, PA device. It supports
Class 1 Master for cyclic and acyclic data exchange, and Class 2 for acyclic services.
The full range of SITRANS LR260 functions is available only over a PROFIBUS PA
network.
PROFIBUS PA is an open industrial protocol. Full details about PROFIBUS PA can be
obtained from PROFIBUS International at www.profibus.com.
Device Configuration tool
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 > Communications and Software >
Process Device Manager.)
SIMATIC PDM
SIMATIC PDM is a software package used to commission and maintain SITRANS LR260
and other process devices. For more detail see
Functions in SIMATIC PDM
on page 37.
Electronic Device Description
In order to use Process Device Manager (PDM) with PROFIBUS PA, you will need the
Electronic Device Description for SITRANS LR260. For details see
Electronic Device
Description (EDD)
on page 38.
Network 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 SIEM8162.gsd is available from the SITRANS LR260 product page on our
web site. Go to www.siemens.com/LR260 and click on Downloads.
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.

G: Communications PA
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: 15 mA for SITRANS LR260.
Allow a current reserve for safety.
PROFIBUS address
A unique PROFIBUS address identifies each device on the network. To set the PROFIBUS
address see Device Address (5.1.) on page 88.
Resetting the PROFIBUS address to 126:
• Via SIMATIC PDM:
a) Open the menu Device – Device Reset and click on Reset Address to 126.
b) Click on OK: the address will be reset to 126, and if the address lock was on, it
will be disabled.
• Via the handheld programmer:
a) Navigate to Service (4.) > Device Reset (4.1.). (You can enter the numeric value
instead of navigating via the Arrow keys.)
b) Press RIGHT Arrow to open Edit Mode then scroll down to DEV ADDRESS and
press RIGHT Arrow to select it. 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 Device
Every 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 Model
STD 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 121
mmmmm
G: Communications PA
Defining 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 device
See
Configuring a new device
on page 38.
Configuring PROFIBUS PA with an S7-300/ 400 PLC
1. 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 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.
Cyclic Data
When 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.
Page 122 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS A5E32337685

G: Communications PA
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 DP Slave.
Status Byte
In 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 V3.01
You can choose which type of status byte will be returned, by enabling or disabling
Condensed Status Mode (COND. STAT. MODE) (3.6.1.). The default setting is Condensed
Status enabled:

• This status remains active for at least 10 seconds:
– after enabling simulation
– after setting the FB to MAN mode
– after a restart (e.g. power down cycle) if the simu-
lation is enabled or the FB is in MAN mode
– after passivation is cleared if simulation is
enabled or the FB is in MAN mode
• In MAN mode the status remains until a subsequent
write command overwrites the OUT value after the
10 seconds have expired.
• In simulation mode the written status is buffered and
appears in the value flow after 10 seconds. However
the new written SIMULATE parameter with its status
can be read before the 10 seconds have expired.
0x74

This Status remains active for 10 seconds after simula-
tion ends.
While this status is active there is no reliable process
value. Measured values and their status are updated
afterwards.

Diagnostics
All diagnostic information shown below is viewable via PDM.
Diagnosis reply (available cyclically)
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 cyclic diagnosis’
and it is 8 bytes long. The last 4 bytes of the extended diagnostic message give the error
code shown. (See
Extended Mode Diagnosis
on page 126 and
Condensed Mode
Diagnosis
on page 126.)
The same infomration is also available acyclically via the Diagnosis Object.
Diagnosis Object (available cyclically or acyclically)
This consists of four bytes.
In PROFIBUS PA there are two possible types of Acyclic Diagnostics:
•Extended Mode Diagnosis
•Condensed Mode Diagnosis
You can choose which of these will be returned, by enabling or disabling Condensed
Status Mode (COND. STAT. MODE) (3.6.1.) on page 80. The default setting is Condensed
Status enabled: Extended Mode Diagnosis will be returned, and the following codes will
be used.
Status Codes for Bad Quality
Values in hex notation Description
0x10...0x1C The LOE timer has expired: this could be caused by LOE or by
a sensor malfunction: value is BAD.
0x04...0x07 There is an error in the configuration of the function blocks in
PROFIBUS PAa).
0x1C...0x1F The function block, or the transducer block, has been placed
out of service.
a) This could happen when a firmware download has been done, but a system reset has not
been done. This could also happen if the function blocks are not configured properly
using the handheld programmer, PDM or acyclic services.

To find the slot and index numbers via SIMATIC PDM, go to Help > Help on Device
Parameters > Communications, and select the appropriate block from the list. For each
parameter, the slot and the relative index is listed. For example.
Each block has a slot number and an Index Offset value.
To get the absolute index for any parameter, add the Index Offset for the appropriate
block to the relative index for that parameter. The parameter takes the slot number of the
block in which it is located.
For example:
• Parameter Static Revision Number has relative index = 1 and is located on AIFB1.
• It has Absolute Index = 17 (relative index 1 + index offset 16).
• It is located at Slot 1 (the slot number for AIFB 1).

Glossary
Glossary
accuracy: 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)

Glossary
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 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 Blanking
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.
1) Many conductive liquids/electrolytes exhibit dielectric properties; the relative
dielectric constant of water is 80.

Glossary
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 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.
