2.4 GSD Files
Supported baud rates are listed in the GSD file (see below). After power-on or PROFIBUS time-
out a baud rate search is active to detect the current transfer speed on the bus. It is not neces-
sary to set the baud rate manually.
If the transfer speed is changed during operation the baud rate search will not be started by
the device. A new power-up or a manual interruption of the PROFIBUS communication is
required to activate the baud rate search in this case.
A “PROFIBUS GSD ZIP” file (e.g. GSD-31777815.zip) including both all KROHNE GSD files and
additional data files can be downloaded from the KROHNE homepage http://www.krohne.com
or contact “KROHNE Marketing”. The GSD file contains information that will be needed for
project planning of the PROFIBUS DP communication network. The relevant data files (e.g.
MFC300_n.bmp; MFC300_n.dib) must be loaded into the bus configuration system/master sys-
tem before start-up of the bus system.
The MFC300 PROFIBUS RS-485 Interface is according to the PROFIBUS PA Profile V 3.01. The
device supports two Ident-No:
•Ident-No. “4510hex” belongs to the GSD file KR014510.GSD and includes the complete func-
tionality concerning the cyclic data exchange of the coriolis mass flow meter MFC300.
•The application of the manufacturer independent Ident-No. “9742hex” (GSD file
“PA039742.GSD”) provides interchangeability of devices, i.e. an exchange of coriolis mass
flow meters of different vendors.
Please follow the instructions in the manual of the host supplier when installing the GSD File
you need and the additional files (MFC300_n.bmp and MFC300_n.dib) into the PLC. If separated
by the bus configuration system the device entry of the MFC300 PROFIBUS RS-485 Interface
with PA Profile 3.01 will be located within the slave family PROFIBUS PA.

“ModeTot” cyclic control data from master to the device via the parameter ModeTot
“SetTot + ModeTot” cyclic control data from master to the device via the parameters SetTot
and ModeTot (in the given order)
The Byte SetTot and ModeTot are being sent cyclically from the Master to the device if these
bytes are inserted as output data via the PLC configurator. The meaning of these control bytes
are as follows:
AI = Analog Input Function Block
FB = Function Block
There are separate settings to select the units for local display and PROFIBUS. Modifications of
the units of the display will have no effect on the data transferred via PROFIBUS. A master
class 2 tool is required to modify the units for PROFIBUS transfer.
During network configuration the user has to define which function block outputs of the
MFC300-DP should be transferred cyclically to the master. This is done by a bus configuration
tool (e.g. for PC-S7 from Siemens this will be done with the tool “HW- Config”). This tool offers
the functions described as follows:
1. It is possible to configure an “Empty” block (the code of an “Empty” block is defined as
0x00) on each block number. This means, that for this block no data is transmitted in the
cyclic data telegram.
2. There is NO “Totaliser (TOT)” function block allowed on block position 1, 2, 3, 7, 8, 9, 10 and
11! An “Analog Input (AI)” function block or an “Empty” block is allowed here only!
Note: All codes supported of “Analog Input (AI)” - and “Totaliser (TOT)” – function blocks will
be found in the corresponding GSD files.
3. There is NO “Analog Input (AI)” function block allowed on block position 4, 5 and 6! A
“Totaliser (TOT)” function block or an “Empty” block is allowed here only!
4. There is a choice of 7 different totaliser functions, which can be allocated to the blocks 4, 5
and / or 6. The 7 functions are defined as follows:

11
Block Number Standard-Configuration
(function block output value)
PA039742. GSD
Ident-No. 9742
Default
unit:
1 Mass Flow AI-FB kg/s
2 Density AI-FB kg/m3
3 Medium Temperature AI-FB K
4 Mass Totaliser Totaliser-FB kg
All other values of ModeTot are not allowed. Value is ignored; totaliser remains in its last valid
setting.
The standard block configuration may be changed by the customer but using the default set-
tings is highly recommended. If the standard block configuration should be changed by the
customer an acyclic master tool must be used to change the “channel parameter” value of the
block which should be connected to another transducer output value.
22..44..22PPrrooffiilleessppeecciiffiiccGGSSDDffiillee::PPAA003399774422..GGSSDD
The functionality of the profile specific GSD file is limited. This GSD file includes only four
blocks:
SSeettTToott::
SetTot =0: Totaliser is totalising.
SetTot =1:
Totaliser will be reset to 0 and stays at 0 until SetTot is switched back again
to 0. If the value of SetTot changes from “1” to “0” the totaliser starts count-
ing from 0.
SetTot =2:
Totaliser is set to the value defined by PresetTot. PresetTot can be written via
a acyclic master (totaliser in block 4 = Slot 4 Index 32; totaliser in block 5 =
Slot 5 Index 32; totaliser in block 6 = Slot 6 Index 32). If the value of SetTot
changes from “2” to “0” the totaliser starts counting from the current value
defined by PresetTot.
SetTot ? 2: not allowed. Value is ignored; totaliser remains in its last valid setting.
MMooddeeTToott::
ModeTot = 0 totaliser totalises positive and negative values.
ModeTot = 1 totalises only positive values.
ModeTot = 2 totalises only negative values.
ModeTot = 3 totaliser is stopped, no totalization will be done.
ModeTot = 248 totalises all values as positive (negative values will be multiplied with “-1.0”)
ModeTot = 249 totalises all values as negative (positive values will be multiplied with “-1.0”)
The device has to be switched from “Manufacturer Specific” (full functionality) to “Profile
Specific” (interchangeable basic configuration) by using a master class 2 tool (IDENT_NUM-
BER_SELECTOR: Slot 0, Index 40 change byte value to 0). After this the device has to be pro-
jected by using the PA039742.GSD file.
22..44..33CCyycclliiccddaattaaeexxcchhaannggee
During network configuration the user has to define which function block outputs of the
MFC300 PROFIBUS RS-485 should be transferred cyclically to the master. Network configura-
tion will be done using one of the GSD files described above. The order of transmission of a
function block always remains the same even if a function block is defined as an “Empty” block
(in this case, no function block output data will be sent to the master and all function block out-
puts following the “Empty” block will move up one position).

The meanings of the status byte (unsigned integer) are given in the following tables
2.5 Profiles
The MFC300 PROFIBUS RS-485 Interface supports the PROFIBUS PA Profile Version 3.01.
The MFC300 PROFIBUS RS-485 Interface with PA Profile 3.01 supports the following blocks:
•One physical block.
This block contains the parameters defined in PA Profile 3.01.
•One transducer block for coriolis mass flow devices.
This block provides the parameters and functions defined in PA Profile 3.01.
•Eight “Analog Input (AI)” function blocks: as default “Mass Flow”, “Density”, “Medium
Temperature”, “Volume Flow”, “Concentration 1”, “Concentration 2”, “Concentration Mass
Flow 1” and “Concentration Mass Flow 2”.
•Three “Totaliser (TOT)” function blocks: as default the first and the third totaliser will
totalise “Mass” and second one will totalise “Volume”
2.6 Data Structure of Function Block Output Values
The data structure of function block outputs consists of 5 bytes: a 4 byte float value (Float
Format according IEEE Standard 754 Short Real Number) followed by a 1 byte status value. If
all 11 function block outputs have been projected (see above), 55 byte will be transmitted.

value:
GGoooodd
((nnoonnCCaassccaaddee))function block output value is ok and can be used without restrictions
GGoooodd
((CCaassccaaddee))will not be supported, because it is not applicable for the device
UUnncceerrttaaiinnfunction block output value can be used but the accuracy can not be guar-
anteed (e.g. function block outputs value has been frozen or A/D converter
is saturated or out of range)
BBaaddfunction block output value is bad - don’t use it for process control!
The „Quality-Substatus“- and „Limit“-Bits will be used for further diagnostics or limit check-
ing.
Attention: 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.
2.7 Diagnosis
If the device internal diagnostic functions detect an error additional information will be sent to
the Master (for further information have a look at the UNIT_DIAG_BIT(i) definitions of the cor-
responding GSD-file).

The PROFIBUS address can also be changed using the PROFIBUS service
“set_slave_add”. The input range is 0...125 according to the PROFIBUS spec-
ification. Address 126 is the default address and cannot be set via the
PROFIBUS service “set_slave_add” - use menu instead to reset to default
address.
