2.5 GSD files for the data transfer

A PROFIBUS GSD ZIP file (e.g. GSD-31777813.zip; including both all GSD files and additional data files) you can get on a CD ROM or can be downloaded from the internet. The GSD file contains information that will be needed for project planning of the PROFIBUS communication network.

The relevant data files (e.g. _ _ _ _ .bmp / _ _ _ _ .dib) must be loaded into the bus configuration system/master system before start-up of the bus system.

2.5.1 Cyclic data exchange

During network configuration the user has to define which function block outputs of the signal converter should be transferred cyclically to the master. Network configuration will be done using one of the GSD files described before. The order of transmission of a function block always remains the same even if a function block is defined as an "Empty" block (if so, no function block output data will be sent to the master and all function block outputs following the empty block will move up one position).

2.5.2 Baud rate

Supported baud rates are listed in the GSD file (see below). After power-on or PROFIBUS timeout a baud rate search is active to detect the current transfer speed on the bus. It is not necessary to set the baud rate manually.

If the data transmission rate 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.

2.5.3 Ident.-No. supported

The signal converter with PROFIBUS RS485 interface is based on PROFIBUS PA Profile V 3.0. The device supports two Ident-No.:

•Ident-No. "4500hex" belongs to the GSD file KR014500.GSD and KR024500.GSD and includes the complete functionality of the electromagnetic flowmeter.

•The application of the manufacturer independent Ident-No. "9740hex" (GSD file "PA039740.GSD") provides interchangeability of devices, i.e. an exchange of electromagnetic flowmeters 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 (_ _ _ _ .bmp and _ _ _ _ .dib) into the PLC.

INFORMATION!

If separated by the bus configuration system the device entry of the PROFIBUS RS485 interface with PA Profile 3.0 will be located within the slave family PROFIBUS PA.

2.5.4 Manufacturer specific GSD files: KR024500.GSD and KR014500.GSD

The manufacturer delivers the GSD files with the entire device functionality, which is listed as follows:

Block	Default configuration	KR024500.GSD	Default
number	Function block output: value and	KR014500.GSD	unit
	status	Ident-No. 4500
1	Volume Flow	AI-FB	m3/h
2	Volume Totalizer	Totalizer-FB	m3
3	Volume Totalizer	Totalizer-FB	m3
4	Mass Totalizer	Totalizer-FB	kg
5	Mass Flow	AI-FB	kg/s
6	Speed Flow	AI-FB	m/s
7	Coil Temperature	AI-FB	K
8	Conductivity	AI-FB	S/m
X	Electronic Temperature	AI-FB	°C
X	Supply	AI-FB	V
	(internal supply voltage for the
	PROFIBUS interface)

•AI: Analog Input Function Block

•FB: Function Block

•X: Block number 1, 5, 6, 7 or 8

There will be two additional output values available by changing the function block channel parameters of the above mentioned "Analog Input Function Blocks".

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.

INFORMATION!

During network configuration the user has to define which function block outputs of the signal converter should be transferred cyclically to the master. This is performed by a bus configuration tool (e.g. "HWConfig" for PC-S7 from Siemens). This tool offers specific functions 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 implies: no data are transmitted in the cyclic data telegram for this block.

2.There is NO "Totalizer (TOT)" function block allowed on block position 1, 5, 6, 7 and 8! On these positions, only an "Analog Input (AI)" function block or an "Empty" block is allowed!

(Note: All codes supported by "Analog Input (AI)" - and "Totalizer (TOT)" – function blocks will be found in the corresponding GSD files.)

3.There is NO "Analog Input (AI)" function block allowed on block position 2, 3 and 4! On these positions, only a "Totalizer (TOT)" function block or an "Empty" block is allowed!

4.There is a choice of 7 different totalizer functions, which can be allocated to the blocks 2, 3 and/or 4.

Definition of totalizer functions

Total	cyclic transfer of the totalizer value with status to the master
SetTot + Total	cyclic transfer of the totalizer value with status to the master + cyclic
	control data from master to the device via the parameter SetTot
ModeTot + Total	cyclic transfer of the totalizer value with status to the master + cyclic
	control data from master to the device via the parameter ModeTot
SetTot + ModeTot + Total	cyclic transfer of the totalizer value with status to the master + cyclic
	control data from master to the device via the parameters SetTot and
	ModeTot (in the given order)
SetTot	cyclic control data from master to the device via the parameter
	SetTot
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)

Both, the Byte SetTot and ModeTot are cyclically sent 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:

Function of control bytes

SetTot

SetTot = 0	Totalizer is totalizing.
SetTot = 1	Totalizer 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 totalizer
	starts counting from 0.
SetTot = 2	Totalizer is set to the value defined by PresetTot. PresetTot can be
	written via an acyclic master (totalizer in block 2 = Slot 2 Index 32;
	totalizer in block 3 = Slot 3 Index 32; totalizer in block 4 = Slot 4 Index
	32). If the value of SetTot changes from "2" to "0" the totalizer starts
	counting from the current value defined by PresetTot.
SetTot > 2	Not allowed. Value is ignored; totalizer remains in its last valid
	setting.
ModeTot
ModeTot = 0	Totalizer totalizes positive and negative values.
ModeTot = 1	Totalizes only positive values.
ModeTot = 2	Totalizes only negative values.
ModeTot = 3	Totalizer is stopped, no totalization will be done.
ModeTot = 248	Totalizes all values as positive, negative values will be multiplied with
	-1.0.
ModeTot = 249	Totalizes all values as negative, positive values will be multiplied with
	-1.0.

All other values of ModeTot not allowed. Value is ignored; totalizer remains in its last valid setting.

The standard block configuration may be changed by the customer but using the default settings is highly recommended. If the standard block configuration should be changed by the customer an acyclic master tool or the device display menu must be used to change the "channel parameter" value of the block which should be connected to another transducer output value.
