1 Technical Description
1.1 PROFIBUS
The PROFIBUS (Process Field Bus) is an open communication system for automation engineering which
is being used in its thousands all over the world and which is specified in the European standard
EN 50170.
1.1.1 General Information about PROFIBUS DP and PA
The PROFIBUS PA is a variant of the PROFIBUS DP which is used widely in production engineering.
The PROFIBUS PA has special a transmission technique and therefore satisfies the requirements of
process automation/materials processing. This transmission technique is defined in the international
standard IEC 61158-2. The low transmission speed reduces the power loss and therefore enables an
intrinsically safe technology for use in areas where there is a high explosion risk. Line, star and tree
structures are possible as well as combinations of these. All kinds of field devices such as transducers,
actuators, analyzers, etc. can be connected to the PROFIBUS PA. The essential advantage in addition to
the saving of installation costs is the possibility of a more detailed diagnosis with an increase in the
availability of the plant components. In addition the automatic updating of plant documentation and plant
optimization during ongoing operation is supported.
Several PROFIBUS PA lines are linked to the fast PROFIBUS DP in an automatic system. The process
control system is also linked to this. Both bus systems use a uniform protocol layer. Thus the PROFIBUS
PA is a communication-compatible extension of the PROFIBUS DP into the field.

Figure 1--1 Typical PROFIBUS automation system
Figure 1--1 shows a section of a typical PROFIBUS automation system. The control system consists of
two masters with shared tasks:
The Master class 1 takes care of the control and regulating tasks, Master class 2 allows operating and
monitoring functions. Measuring and actuating data are exchanged cyclically between Master class 1 and
the field devices. The status information signals of the field devices are transmitted parallel to these data
and evaluated in the class 1 master. No field device parameters are set or other device information read
during cyclic operation. The information necessary for establishing communication is available to the
control system from the stored, device-specific device data base files GSD.
One or more class 2 masters can access the field devices acyclically in addition to the cyclic mode. With
this communication type further information can be fetched from the devices or settings made in the
devices.

1.1.2 Properties of the PROFIBUS PA
The PROFIBUS PA (PA = Process Automation) enables di-directional communication between a bus
master and the field devices over a two-wire cable. At the same time the power is supplied to the two-wire
field devices through the same cables (current I in Figure 1--1).
Supplementary to the EN standard 50170, the PNO (PROFIBUS user organization) has defined the scope
of functions of the individual field device types in a so-called profile description. These profiles define the
minimum functional requirements and optional extensions. The device-internal “Device Management”
supplies all the necessary basic information for finding the profile parameters to the control system
configuration tools. In this way a parametering tool can operate all devices which conform to profile no
matter what their type and manufacturer.
The system must be implemented with one or more PROFIBUS PA lines depending on the automation job
and thus the number of field devices. A PROFIBUS PA line consists of the components illustrated in
Figure 1--2.

Figure 1--2 PROFIBUS PA architecture
The central process control system PLS or, in the case of low requirements, a PC, is responsible for the
control. As a rule the functions signal conversion DP-PA, bus feeding and bus termination are unified in the
“coupler” device. A DP/PA coupler or, in the case of higher requirements, a more powerful DP/PA link is
used depending on the number of PROFIBUS PA field devices to be operated in the automation system.
An additional terminating resistor must be fitted at the far end of the bus for transmission-technical
reasons. The theoretically possible line length (total of all line sections) is a maximum 1900 m (see
chapter 2.1) when using the recommended bus cable. However, the current requirements of the individual
users and voltage drop at the cable must also be taken into account in the planning. The individual field
devices FD can be connected almost anywhere in the bus system. See the “PNO Guide
PROFIBUS PA” /1/ for further information.
The DP/PA coupler or DP/PA Link is supplied by a power supply unit with safety extra-low voltage (SELV).
This power supply must have adequate reserves for bridging brief power failures.
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:
Current IS< 128 mA, voltage U0<15V

Instruction Manual
6SITRANS F with PROFIBUS PA
C79000-B5676-C114-03
!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 given by the total of maximum current
consumptions of the connected devices (³10 mA per device is the standard). A current reserve should be
planned for safety, otherwise there is a risk that a defective device overloads the bus with its increased
current consumption and the power supply and communication with all unaffected users could collapse.
The power reserve quantity depends on the current increase in the event of an error specified by the
manufacturer.
The electronic current limiter installed additionally in the SITRANS F/PA ensures that the current does not
increase by more than 5 mA even when a device is defective.
Every device has its own address to distinguish between the connected process devices. The address
setting is described in the chapter 3 “Commissioning”.
See the System Description Field Technology /2/ for further information about components, setup
regulations and planning.
1.2 Function of the Device

interface and the omission of the digital output 2. This means that the basic functions of the device
including the operation and display remain basically the same. Function blocks 1 to 6 take care of the
interface tasks to the bus.

measured values, status and device data on the bus.
2 The device internal electronics are isolated from PROFIBUS PA by the potential isolator.
3 The bus interface contains the transmit and receive circuits for the bus system.
4 The electronic current limiter ensures that no illegally high current flows in the event of an error. This
avoids bus overloading, data communication with the other, unaffected users is maintained.
5 The reverse polarity protection enables the bus cables to be connected at any terminals and makes
installation errors almost impossible.
6 An EMC filter prevents malfunctions in the case of electromagnetic interference.

1.3 Scope of Functions
SITRANS F provides the following measured values and values derived from measured values using
PROFIBUS and local display.
·Flow (volume or mass flow)
·Sound velocity
·Temperature
·Ultrasonic amplitude
·Quantity (volume or mass) net, forward and reverse
An upper and lower limit can be specified for all measured values. An appropriate message is indicated in
the measured value status (see description 4.1.1.1) when a limit value is reached. Diagnostic messages
are also indicated in the event of malfunction or special states (see description below).
SITRANS F has a wide range of setting facilities, for example, measuring range scaling, definition of the
flow direction, residual flow suppression, attenuation of measured values etc. The settings are made on
the PROFIBUS or using the local keyboard with menu guidance.
The quantity values (volume and mass) are derived from the flow value by accumulation (volume or mass
forward from all positive flow values, volume or mass reverse from all negative flow values, volume or
mass net from all flow values with the correct sign) and also have setting facilities for the limit values but
no scaling.
The flow values can also be issued as a frequency or pulse sequence at “digital output 1”.
Status information on quality and compliance with limit values is provided with the measured values.
Further diagnosis data can be called up if there are device errors.
The following functions are implemented in addition to the standard device according to the PROFIBUS
device profile:
·User-specific scaling of all measured variables in the form of a linear representation
between any range of the measured variable (“measuring scale”) and the actual output
variable (“output scale”).
·A measuring range does not need to be set, the valid measuring range is only limited
by the respective sensor limits (see Table 5--1, page 30).
·Upper and lower warning limit for each measured variable to supplement the existing
alarm limits.
·Upper and lower warning and alarm limits for each totalizer, with selectable hysteresis
for the net totalizer.
The following functions on the standard device with 20 mA/HART interface are not available on the
PROFIBUS version as they can generally be replaced indirectly by the PROFIBUS functions.
·Analog output (4 to 20 mA)
·HART communication
·Digital output 2 (relay output)

2 Installation
2.1 Electrical Connection
!Warning
·The pertinent regulations must be observed for electrical installation, in
explosion risk areas in particular:
- the rules and regulations governing the erection and operation of plants in
explosion risks areas (e.g. in Germany: Elex V, DIN VDE 0165)
- the EC Type Examination Certificate
- the power supplied from the coupler may not exceed the maximum values
specified in the EC Type Examination Certificate of the SITRANS F. The
device may no longer be connected to intrinsically safe circuits if these
values have been accidentally exceeded.
·Do not install the device under voltage. Danger of electric shock!
·The version for power supply UC 19 to 30 V may only be connected to SELV
or PELV circuits.
The following rules apply generally for laying the bus cable:
- Only use shielded, two-wire cables
- Only use the recommended cable types, e.g.:
in intrinsically safe circuits: Siemens 6XV1 830-5AH10 (color blue);
in circuits with enhanced safety or non-Ex applications:
Siemens 6XV1 830-5BH10 (color black)
- Lay cable separately from cable with voltages > 60 V
- Avoid laying near to large electrical installations
- The specifications only apply for properly executed installations.
Make the electrical connection as follows:
- The cables used for connecting must have the specified outside diameters.
- Compare the data on the rating plate with the local power supply.
- Release the catch on the cover of the terminal compartment by turning the 3 mm hexagon socket
screw.
- Unscrew the cover from the terminal compartment.
- Push the power cable and the bus cable through the cable gland up to the terminal block. Lay the cable
in a bend in front of the cable gland to prevent moisture getting into the terminal block.
- Make the connection as shown in Figure 2--1.
- Connect the PE cable of the power supply to the earth terminal in the terminal compartment. Use a
cable length so that the PE conductor is the last to come away when you pull the cable.
- Mount the cover for the power supply terminals in devices with ignition protection II 2G EEx dem[ia] IIC
T6.
- Tighten the cable gland and check strain relief.
- Screw the cover tightly to the housing, do not use a tool. The sealing ring must be clean and
undamaged.
- Mount the cover catch.

Figure 2--1 Electrical connection
A bus termination must be fitted at both ends of the bus for error-free communication (see Figure 1--2). At
the end nearest the control system this is already ensured by the bus termination contained in the coupler
or link. An additional termination must be fitted at the far end of the bus.
!Warning
Only approved bus terminations, branches, cables etc. may be used in intrinsically
safe circuits.
The specified immunity and radiated emission are only guaranteed if the bus shielding is fully effective.
This includes connecting the shields to the metal connections of the SITRANS F/PA but also laying the
shields to the terminal compartment, distributor, DP/PA coupler or DP/PA link.
A suitable potential equalizer must be provided to avoid potential differences between the individual plant
parts and thus the risk of malfunctioning. Refer to DIN VDE 0100 Part 410 and Part 540 for information on
dimensioning and design.
General information about PROFIBUS installation can be found in the PNO guide /1/.
3 Commissioning
Make sure the device addresses are set before operating two or more field devices on the bus. Every
address may only be assigned once so that there is no confusion. Basically an address range of 1 to 125
is possible; address 126 is set in the as-delivered state. Usually the lower addresses are assigned to the
masters in PROFIBUS systems. Therefore we recommend starting the address for the device at 30. The
addresses are set with the operation and monitoring module in menu item 4.1.1 or acyclically using
PROFIBUS.

4 Operation, Communication
4.1 PROFIBUS Communication
SITRANS F has a PROFIBUS PA connection corresponding with IEC 1158 (synchronous transmission).
The only possible baud rate is 31.25 kbits/s. The min TSDR (smallest station delay time, chapter 5.4.1,
Seite 32) at startup is 11 bit times and can subsequently be changed using the Set_Prm service. The bus
address has the value 126 as-delivered and can either be changed with the Set_Slave_Add DP service or
on the local keyboard (menu 4.1.1).
Communication uses the EN 50 170 standard (PROFIBUS DP and DP V1). The data transmission and
data formats will be described in the following sections.
The following DP services are supported as slave for a DP master class 1:
DData_Exchange
DRd_Inp
DRd_Outp
DSet_Prm
DChk_Cfg
DSlave_Diag
DSet_Slave_Add
DGlobal_Control
DGet_Cfg
The following DVP1 services are supported as slave for a master class 2:
DMSAC2_Initiate (indication and response)
DMSAC2_Abort (request, indication and response)
DMSAC2_Read (indication and response)
DMSAC2_Write (indication and response)
4.1.1 Cyclic Data Transmission
Cyclic data transmission is used to transmit input and output data between Master class 1 (control system
or PLC) and the slave (SITRANS F).
Up to seven different measured values (= modules) can be transmitted cyclically as input data in a
telegram with the Data_Exchange service. The following measured values are available in the order
specified:
1. Flow (volume or mass flow)
2. Sound velocity
3. Quantity (volume or mass) net
4. Temperature
5. Ultrasonic amplitude
6. Quantity (volume or mass) forward
7. Quantity (volume or mass) reverse
Output data are sent to the device together with the cyclic request telegram. The number and type of the
data actually transmitted can be defined with the configuration data (see GSD, chapter 4.1.1.3, page 15).

The transferred value is effective until it is changed, i.e. after the value 1 (reset totalizer) is sent, for
example, the totalizer will remain on the value 0 until the SET_TOT parameter is changed again.
Each SET_TOT value affects the corresponding totalizer independently of the others. The quantities are
also cumulated independently of each other, i.e. the net quantity does not have to be equal to the sum of
the quantity forwards and quantity reverse especially if a totalizer has been reset or was preset.
4.1.1.3 Device Data Base File (GSD File)
The device data base file (GSD file) is used to configure the format and order of the cyclical data. The
standard GSD for ultrasonic flow transducers described in profile 3.0 and which does not support
manufacturer-specific expansions can be used alternatively to the device-specific GSD (“siem8091.gsd”,
see appendix 9). The “IDENT_NUMBER_SELECTOR acyclic parameter must be set to select the GSD
(0 = profile GSD, 1 = manufacturer-specific GSD = factory setting).
All permitted identifiers are listed in the GSD for each measured value (= module). They can be combined
freely with the limitation that only one identifier can be used per module and the order of the identifiers
must coincide with the order of the modules.
The identifier formats “short” (identifier byte) and “long” (extended identifier) are accepted for the flow,
sound velocity, temperature and ultrasonic amplitude. The “long” and “resettable quantity ... long” are
accepted for the totalizer modules. The identifiers are checked independently of each other, i.e.
combinations with different formats are permitted when several measured values are queried. At least one
measured value must be queried, i.e. the number of the identifier must be at least 1 and may be
maximum 7.
The order of the measured values in the cyclical telegram defined in the GSD is set and cannot be
changed (see also chapter 4.1.1, page 11).
For the configuration data this means that the first identifier always represents the flow, the second the
sound velocity, ... , the last the quantity reverse. If you want to omit a measured value, set “Free Place” as
the identifier.

Example:
The measured values sound velocity, temperature and ultrasonic amplitude are to be transmitted. The
following identifier combination should set:
1. Free Place (for flow)
2. short Identifier or long Identifier (for sound velocity)
3. Free Place (for net quantity)
4. short Identifier or long Identifier (for temperature)
5. short Identifier or long Identifier (for ultrasonic amplitude)
An identifier is not required for the forward quantity and reverse quantity as the ultrasonic amplitude is the
lastvaluetobetransmitted.
Output data can only be transmitted and therefore the totalizer reset if the corresponding “extended
Identifier” (long) is used. The first byte of the output data always refers to the first resettable totalizer.
If, for example, the “Resettable quantity forw. (long)” and “Resettable quantity rev. (long)” identifiers for the
forward and reverse quantity are set but the “Resettable quantity net (long)” identifier is not set for the net
quantity, i.e. the net quantity totalizer is the only one which cannot be reset, the first byte of the output data
will refer to the totalizer for the quantity forward.
4.1.2 Acyclic Data Transmission
The acyclic data transmission is mainly used for remote control of devices, i.e. for transmitting parameters
during commissioning, maintenance, batch processes or for displaying further variables which do not take
part in the acyclic input and output data transmission.
Acyclic accesses can be carried out by Master class 1 (C1 connection) or Master class 2 (C2 connection).
Sitrans F supports up to 4 simultaneous C2 connections.
The approximately 400 parameters including address (slot and index), format, range of values, start value
and attributes are compiled in an object list “Obj8091.rtf” which is available on request.
We recommend using the SIMATIC PDM software package and a PC (compatible with industry standard)
or a programming unit with the following minimum specifications should preferably be used for acyclic
operation:
Hardware:
D80486 processor or higher
DAt least 32 MB RAM
DHard drive with at least 70 MB free space
DMonitor: VGA standard or MS Windows compatible
DKeyboard and mouse (optional)
DCD-ROM drive
DCP5411 A2, CP5511 or CP5611 interface
Software:
DWindows 95 or Windows NT
DSIMATIC PDM V5.01 or higher (SIMATIC STEP 7 OEM included)
Integrated Help functions support use of SIMATIC PDM.

4.1.3 Diagnosis
The diagnostic data can be requested with the Slave_Diag service. If extended diagnostic messages exist,
this is displayed with the Diag_Flag of the Data_Exchange service. If the master then calls the Slave_Diag
service, the user diagnostic data are supplied in the following form:

Table 4--8 Format of complete diagnostic data
The total length of the external diagnostic data is always 8 bytes including the header.
The Diag_Flag is always set when the last 4 bytes of the diagnostic data (corresponds with the
DIAGNOSIS parameter) have changed since the last message therefore also, for example, when the
diagnostic messages disappear again so that the master register each change in the diagnostic data.
If a diagnostic message is active, the corresponding bit is set or reset.
The following bits in the external diagnostic data are supported by SITRANS F all other bits always remain
reset:
Bit no. Description Meaning
0Error appears At least one bit in the subsequent 4 bytes (DIAGNOSIS) has
been set
1Error disappears At least one bit in the subsequent 4 bytes (DIAGNOSIS) has
been set
2 ... 7 reserved -- -- --
Table 4--9 Format of byte 4 diagnostic data
The “Error appears” message has priority over the “Error disappears”, i.e. if a diagnostic bit is set and
another reset at the same time, “Error appears” will be displayed.

The DIAGNOSIS part contains device diagnostic messages and has the following structure
(bit 0 = LSB, bit 7 = MSB):
Bit no. Description Meaning Causes (= local message)
0DIA_HW_ELECTR Hardware failure of the

4DIA_MEM_CHKSUM Memory error “EEPROM error”
“RAM error”
5DIA_MEASUREMENT Measurement failure “Unreliable flow value”
“Measuring path error” (affects
flow, sound velocity and
ultrasonic amplitude)

The bits in DIAGNOSIS take over the function of a collective message in most cases which can then be
broken down in more detail using the local messages.
The EXTENSION_AVAILABLE bit indicates that there is further diagnostic information, essentially details
on the DIAGNOSIS message. This information is displayed locally. The messages related to measured
values are also transmitted with the measured values in the status byte (substatus).

4.2 Local Operation and Display
The menu structure for local operation is mostly repeated in the SIMATIC PDM PC user interface. It is
based on the block structure which is a mandatory setting from the PROFIBUS PA profile. Substantial
differences from the menu structure of the device with HART communication therefore cannot be avoided.
The complete menu structure is therefore given in the following table:
