1 SAFETY INSTRUCTIONS

1.1 Scope of the document

These instructions are supplementary to the signal converter Handbook. For all other data, use the relevant chapters of the Handbook. If you do not have this document, please contact the nearest office or download them from the manufacturer's internet site.

INFORMATION!

The information in this chapter only contains the data applicable to PROFIBUS communication. The technical data in the Handbook shall be valid in its current version, provided that it is not rendered invalid or replaced by this supplement.

1.2 Scope of delivery

A device for PROFIBUS communication is supplied with:

IFC 300

• Supplementary instructions for PROFIBUS communication

• PROFIBUS device data files (GSD) on a CD-ROM supplied with the device

1.3 Special notes

Don't switch off (power off) the signal converter immediately after manual change of parameter values:

• Please wait approx. 10 seconds before you switch off the signal converter after you have done both a parameter download via PROFIBUS or a manual change of a parameter value via the local display.

• Please wait approx. 15 seconds before you switch off the signal converter after you have carried out a "Factory Reset" (PROFIBUS "Coldstart") via PROFIBUS or local display.

"Deactivation of the Service Parameter Lock" of the signal converter via PROFIBUS:

• After writing down the service password (via PROFIBUS) the "Deactivation of the Service Parameter Lock" will last at least 10 minutes if the internal password timer of the signal converter won't be retriggered by writing this password again. The "Deactivation of the Service Parameter Lock" will be terminated at once by a PROFIBUS Coldstart / Warmstart or if the internal password timer of the signal converter elapsed.

The following diagram shows a typical network configuration with PROFIBUS devices with RS485 interface in a non-hazardous environment. The PROFIBUS devices with RS485 interface do not need any segment coupler. They are connected directly to the PROFIBUS DP network.

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

output data will be sent to the master and all function block outputs following the empty block

output data will be sent to the master and all function block outputs following the empty block output data will be sent to the master and all function block outputs following the empty block will move up one position)

will move up one position).

will move up one position)will move up one position)

2.5.2 Baud rate

(if so, no function block

(if so, no function block (if so, no function block

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.

• 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. "HW- Config" 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

ModeTot + Total cyclic transfer of the totalizer value with status to the master + cyclic

SetTot + ModeTot + Total cyclic transfer of the totalizer value with status to the master + cyclic

SetTot cyclic control data from master to the device via the parameter

ModeTot cyclic control data from master to the device via the parameter

SetTot + ModeTot cyclic control data from master to the device via the parameters

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:

IFC 300

control data from master to the device via the parameter SetTot

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.
