2.3 Function blocks and the PROFIBUS PA Profile
The Analog Input Function Block agrees with PROFIBUS PA Profile 3.02. The Analog Input
Function Block is the data interface to a process control system (a PLC, ...). The control system
(cyclic communication services) can read data.
The device has these blocks:
The level transmitter is a modular device with 4 slots. Each Analog Input Function Block uses
one slot (as a virtual module). The user cannot change this setting. But the user can change the
measurement name and unit for each Function Block. Refer to the table that follows:
If you change device-specific parameters, we recommend that you set device and system length
units to millmetres (mm). New settings are rejected if system length units and device length
units are different.
INFORMATION!
The PROFIBUS PA Profile 3.02 has a standard set of parameters and functions available for
PROFIBUS devices used in process control. The PROFIBUS device is a function block application
in which parameters and functions are grouped into different blocks.
Block Usage
1 Physical Block (PB) contains identification and diagnosis parameters of the device
1 Transducer Block contains parameters and functions to control the level measurement
4 Analog Input Function Blocks
(AI-FB) contains parameters and functions to control the measuring output; provides the measuring value(s)
INFORMATION!
If it is necessary to change the measurement name, change the channel parameter in the acyclic
PROFIBUS services.

3.1 Topology of a PROFIBUS PA network
The following diagram shows a typical network configuration with PROFIBUS PA devices in
hazardous and non-hazardous areas, as well as the connection of conventional non-PROFIBUS
devices (e.g. with 4 …20 mA signals) to a PROFIBUS network.
The PROFIBUS PA segment is connected to a segment coupler which, among other things,
provides the conversion to the PROFIBUS DP bus line. In addition it provides the power supply for
bus–powered PROFIBUS PA devices. Refer to the instruction manual of the segment coupler
concerning the DP bus parameters, e.g. the supported baud rates.
Refer also to the PROFIBUS PA User and Installation Guideline (Version 2.2, February 2003 PNO
Order No. 2.092).

3.2 Electrical connection for signal converter
Bus cable - Shielding and grounding
The statements of the FISCO model only apply if the used bus cable meets the required
specifications.
In order to ensure optimum electromagnetic compatibility of systems it is important that the
system components, and in particular the bus cables, are shielded. Gaps in the shields must be
as small as possible.
Use the shortest possible length of shield wire to connect the electrical cable to the grounding
terminal.
INFORMATION!
The PROFIBUS PA interface of the signal converter will operate only if the power supply is
connected/available. The device terminal is not sensitive to electrical polarity.

4.1 Hardware settings
There is a DIP switch block with 8 switches on the level transmitter module to set the PROFIBUS
device address and prevent changes to the station address from the network.
Figure 4-1: How to use the DIP switches to change the station address
1 Hardware DIP switch
OFF: The user can set the station address with the network bus
ON: The user can set the address of the device with the 7 other DIP swtiches (item 2). You cannot use the network bus
or the local display to change the station address.
2 7 "Station Address" DIP switches. Each DIP switch is a bit position (bits 0...6). Bit 0 is on the left side of the switch
block.The base 10 value of each bit is given in the table that follows. This data is used to calculate the "Station Address"
number.
OFF: binary number "0".
ON: binary number "1".
INFORMATION!
If the Hardware DIP switch is set to "ON", the hardware is locked and you cannot use the network
bus to change the station address.

Station address: DIP switch positions
The station address is calculated by adding the "ON" values of each switch on the DIP switch
block. The default setting for each switch is “OFF”.
If you change the DIP swtich positions, start the device again to use the new settings. If you use
the "Set_Slave_Add" service or "FACTORY_RESET code 2712" (reset station address to its
default value) to change the station address, it is not necessary to start the device again to use
the new settings.
Station address
•If the "Station Address" DIP switches are set to a correct station address (≤125) and the
"Hardware" DIP switch is set to "ON", the device uses the DIP switch setting as the station
address. The Set-Slave_Add service is ignored in this mode. The Set_Slave_Add service is not
available for Automatic Ident. Number adaptation at this time. Physical block parameter
FACTORY_RESET code 2712 is rejected.
•If the "Hardware" DIP switch is set to "OFF", the device does not use the new setting. If the
"Station Address" DIP switches are set to an incorrect address (>125) and the "Hardware"
DIP switch is set to "OFF", the device does not use the new setting. The Set_Slave_Add
service or the Physical block parameter FACTORY_RESET code 2712 (reset station address to
its default value) can be used to change the station address and for Automatic Ident. Number
adaptation. The Physical block parameter FACTORY_RESET code 2712 can also be used to
change the station address.
•If the "Station Address" DIP switches are changed from an incorrect address to a correct
address and the Hardware" DIP switch is set to "ON", the device uses the "Station Address"
DIP switch setting.
•If the the "Hardware" DIP switch is set to "OFF", the device will use the last correct setting for
this mode. If the "Station Address" DIP switches are changed from a correct address to an
incorrect address and the "Hardware" DIP switch is set to "OFF", the device will use the last
correct setting for this mode. If there is no station address set at this time, the device will use
the default address 126.

4.2 GSD files
The GSD file contains information that will be needed for configuration of the PROFIBUS DP
communication network. Supplementary files (e.g. ___.bmp and ___.dib) contain icons which will
represent the PROFIBUS devices in the view of the bus configuration system/master system. The
files must be loaded into the configuration program before you connect the device to the
network. Follow the instructions in the manual of the host supplier when installing GSD file and
supplementary files.
The GSD files of all KROHNE devices with PROFIBUS PA interface are available at the KROHNE
internet site for download.
4.3 Ident. Number
You can use a software-based engineering tool (DD, DTM etc.) and the parameter
IDENT_NUMBER_SELECTOR to change the Ident. Number.
Ident. Numbers identify the types of PROFIBUS slave used in a PROFIBUS network. There is one
Ident. Number for each type of PROFIBUS slave. This level transmitter can use more than one
Ident. Number. Thus, the device can have more than one configuration in the PROFIBUS
network. When the Ident. Number is changed, the cyclic data transfer rate changes. This permits
the network to change the quantity of measurement data and diagnostic data transmitted by the
device.
The level transmitter can use the settings that follow:
•Automatic adaptation mode (factory setting)
•Manufacturer specific Ident. Number (4550hex)
•Profile specific Ident. Number (9700hex)
Automatic adaptation mode (factory setting)
Automatic adaptation mode (factory setting)Automatic adaptation mode (factory setting)

INFORMATION!
Failure of the automatic adaptation mode can occur. When this failure occurs, you must use a
software-based engineering tool and the parameter IDENT_NUMBER_SELECTOR to set the
Ident. Number to a constant value.

4.4 Configuration of cyclic data transfer
During network configuration the user has to select which function block input/output data shall
be transferred between the PROFIBUS master and the PROFIBUS slave. The GSD file described
above contains several types of modules for this purpose. During configuration a module has to
be assigned to each slot of the device in order to select which data has to be transferred for the
corresponding function blocks. The cyclic layout (see section Ident. Number selector) shows
which module types are valid for each slot. The order of transmission of the data always remains
the same. If an “Empty Module”is assigned to a slot no data will be sent for the corresponding
function block and all function block data following this empty module will move up one position.

4.5 Cyclic data
In a PROFIBUS network cyclic data is described from the point of view of the master. Therefore
input data is transferred from the slave to the master while output data is transferred from the
master to the slave.
4.5.1 Input data
Input data is transferred from the level transmitter to the master for the measuring value. If
input data transfer is configured, 5 bytes are transferred for the corresponding slot:

Status value
The PROFIBUS interface of the level transmitter supports the PROFIBUS-PA Profile Version
3.02. In this Profile the Condensed Status and Diagnosis has replaced by default the Classic
Status and Diagnosis of the PROFIBUS-PA Profile Version 3.0. The Condensed Status and
Diagnosis has been created to make diagnostic events more obvious and to allow predictive and
preventive maintenance. Nevertheless Classic Status and Diagnosis is still available for the level
transmitter. It is implemented for backwards compatibility to "older" devices or PLC systems
which do not support Condensed Status and Diagnosis.
The device may be switched between "Condensed Status and Diagnosis" and "Classic Status and
Diagnosis"
•automatically during start-up of the cyclic data transfer by setting the parameter PRM_COND
within the Set_Prm service data.
•using an engineering tool (e.g. DD/DTM) to write the parameter COND_STATUS_DIAG (slot 0,
index 43).
Coding for both parameters is:
•0: Classic Status
•1: Condensed Status (factory setting)
The coding of the status value depends on the active status and diagnosis mode. It is described in
the following tables.
Condensed Status
Condensed StatusCondensed Status
Condensed Status
The Condensed Status codes have been defined to allow easier decoding of the information
provided by the PROFIBUS devices. The coding is shown in the following table:
INFORMATION!
The parameter COND_STATUS_DIAG cannot be modified directly if cyclic data transfer is active.
Nevertheless it is reset to the factory setting if a reset to default data is requested by an
engineering tool.

Status = Limits
Check the first two quality bits in order to get the quality information of the measurement value:
•Good (Non Cascade):
Good (Non Cascade):Good (Non Cascade):
Good (Non Cascade): function block output value is ok and can be used without restrictions
•Good (Cascade):
Good (Cascade):Good (Cascade):
Good (Cascade): will not be supported, because it is not applicable for the device
•Uncertain:
Uncertain:Uncertain:
Uncertain: function block output value can be used but the accuracy can not be guaranteed
(function block outputs value has been frozen, A/D converter is saturated or out of range, ...)
•Bad:
Bad:Bad:
Bad: function block output value is bad - do not use it for process control!
The "Quality-Substatus" and "Limit" bits will be used for further diagnostics or limit checking.

The status should be monitored because a number will be transmitted even if the status of the
measurement value is bad or uncertain. This is the only way to check the quality of the
transmitted measurement values.

4.6 Diagnosis
The device does internal self-tests. The results are given as detailed diagnosis data that agrees
with PROFIBUS PA Profile 3.02. You can set device parameters to see the diagnosis data and you
can also use an engineering tool (DD, DTM etc.) to read it. Cyclic services transfer diagnosis data
to the control system (PLC etc.).
Diagnosis is bitwise coded. Thus it is possible to report more than one indication simultaneously.
The GSD file contains a text for each diagnosis bit to show a text message in the control system.
The references are specified in the UNIT_DIAG_BIT(i) entries. They show which bit is set to
indicate a special diagnosis event.
The quantity and content of diagnosis data depends on the device settings. The active Ident.
Number and the selected status and diagnosis mode will have an effect on diagnosis
propagation. The tables that follow show the diagnosis events which are reported for different
settings. The bit number is equal to the count in the GSD file. It gives the position in the device-
related diagnostic field of the Slave_Diag service.
