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
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.
A device for PROFIBUS communication is supplied with:
MFC 400
Supplementary instructions for PROFIBUS communication
PROFIBUS device data files (GSD) which can be also downloaded from the manufacturer's
internet site
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.
CAUTION!
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 20 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.

2.5 PROFIBUS PA Profile implementation
The PROFIBUS PA Profile 3.02 defines standardized parameters and functions for PROFIBUS devices used for process control. It describes a PROFIBUS device as a function block application, i.e. parameters and functions are grouped into different blocks. In the MFC 400 PROFIBUS device the following blocks are implemented:
Block Usage
1 Physical Block (PB) contains identification and diagnosis parameters of the device
1 Flow Transducer Block (TB)
8 Analog Input Function Block (AI-FB)
3 Totalizer Function Blocks (TOT-FB)
The Analog Input Function Block and the Totalizer Function Blocks provide the data interface towards a process control system (e.g. a PLC); i.e. their input/output data can be read/written by the control system. In a PROFIBUS network this is done via cyclic communication services.
contains parameters and functions to control the flow measurement
contains parameters and functions to control the measuring output; provides the measuring value(s)
contains parameters and functions to control/provide the counter value(s)
PROFIBUS DP 2
From the PROFIBUS point of view the MFC 400 device is designed as a compact device with 11 slots. While the Analog Input function blocks are assigned to slot 1, 2, 3, 7, 8, 9, 10 and 11 the Totalizer Function Blocks are assigned to slot 4, 5 and 6. This assignment is fixed and cannot be modified by the user. Nevertheless during network configuration the user can choose which function block data shall be transferred between the PROFIBUS master and the PROFIBUS device.
2.6 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. Follow the instructions in the manual of the host supplier when installing GSD file and supplementary files.
A PROFIBUS GSD ZIP file (e.g. GSD-4002171502.zip) including both all GSD files of all KROHNE devices with PROFIBUS PA interface and all additional data files mentioned above are available at the KROHNE download page (e.g. http://www.krohne.com/html/dlc/GSD-4002171502.zip).
INFORMATION!
If it is supported by the host configuration tool the device entry for the MFC400 PROFIBUS device will be located within the slave family "PROFIBUS PA".

2 PROFIBUS DP
2.7 Ident. Number selector
Within a PROFIBUS network the type of a PROFIBUS slave is identified by its Ident. Number which is unique for this slave type. The PROFIBUS DP device supports two different Ident. Numbers. Therefore it can be installed for different use cases. When the Ident. Number is changed the behaviour of the device concerning the cyclic data transfer is changed; i.e. the maximum number of transferred measuring values and/or the length and content of the diagnosis information will be different. The user can select the required Ident. Number by an engineering tool (e.g. DD/DTM - parameter IDENT_NUMBER_SELECTOR slot 0; index 40) or via the MFC 400 device display menu (menu item "Identification No.", C6.8.7).
The following settings are supported:
Automatic adaptation mode (factory setting)
Manufacturer specific Ident. Number (4512 hex)
Profile specific Ident. Number (9742 hex)
Automatic adaptation mode (factory setting)
If the parameter IDENT_NUMBER_SELECTOR is set to this mode the device will select its operation mode during start-up of the cyclic data transfer according to the used GSD file. The active Ident. Number is set to one of the settings described below. If the IDENT_NUMBER_SELECTOR is changed to this mode the current Ident. Number is not changed until the cyclic data transfer is (re-)started.
MFC 400
INFORMATION!
Depending on the components in the PROFIBUS network the automatic adaptation might fail. In this case the active Ident. Number has to be selected by the user via an engineering tool or via the device display menu. The parameter IDENT_NUMBER_SELECTOR has to be set to a fixed Ident. Number.

2 PROFIBUS DP
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 "Totaliser (TOT)" function block allowed on block position 1, 2, 3, 7, 8, 9, 10 and 11!
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 "Totaliser (TOT)" be found in the corresponding GSD files.)
3. There is NO "Analog Input (AI)" function block allowed on block position 4, 5 and 6! On these
positions, only a "Totaliser (TOT)" function block or an "Empty" block is allowed!
4. There is a choice of 7 different totaliser functions, which can be allocated to the blocks 4, 5
and/or 6.

Profile specific Ident. Number (9742 hex)
Functionality is reduced to the requirements which are mandatory in the PA Profile; e.g. 3 x AI­FB and 1 x TOT-FB are available for cyclic data transfer only. Device specific diagnosis information is not available via cyclic PROFIBUS services. Nevertheless this behaviour will improve interchangeability between devices of different vendors because only functions are available which are provided by all PROFIBUS PA variable area flowmeters. Exchange is possible without modifying the configuration of the control system.

2.9 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.

3.2 System configuration of PROFIBUS PA network
The following diagram shows a typical instrumentation with PROFIBUS PA devices with MBP interface in hazardous and non-hazardous locations, including connections of conventional devices (e.g. with 4...20 mA signals) in a PROFIBUS network.
As a rule, the PROFIBUS PA segment is connected to a segment coupler which, among other things, carries out the conversion to the PROFIBUS DP bus line. It should be mentioned that the segment coupler is normally set to a fixed baud rate on the DP side.
