The PROFIBUS DP device has a RS485 interface to connect the device to a PROFIBUS DP network.
The software supports the PROFIBUS PA Profile 3.02. Both, cyclic services towards a control system (e.g. PLC) as well as acyclic services for operating with engineering tools (e.g. DD/DTM based tools) are supported.
The PROFIBUS station address can be set via PROFIBUS services or via the device display.
2.2 System configuration of PROFIBUS DP network
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 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 UFC 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 |
contains parameters and functions to control the flow measurement |
|
(TB) |
|
|
|
|
|
6 |
Analog Input Function Block |
contains parameters and functions to control the measuring output; |
(AI-FB) |
provides the measuring value(s) |
|
|
|
|
3 |
Totalizer Function Blocks |
contains parameters and functions to control/provide the counter |
(TOT-FB) |
value(s) |
|
|
|
|
The Analog Input Function Blocks 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.
From the PROFIBUS point of view the UFC 400 device is designed as a compact device with 9 slots. While the Analog Input function blocks are assigned to slot 1, 2, 6, 7, 8 and 9 the Totalizer Function Blocks are assigned to slot 3, 4 and 5. 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 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.
INFORMATION!
If it is supported by the host configuration tool the device entry for the UFC400 PROFIBUS device will be located within the slave family "PROFIBUS PA".

2 PROFIBUS DP |
UFC 400 |
|
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 UFC 400 device display menu (menu item "Identification No.", C5.8.6).
The following settings are supported:
•Automatic adaptation mode (factory setting)
•Manufacturer specific Ident. Number (UFC400)
•Profile specific Ident. Number (Profile)
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.
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.

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 is transmitted in the cyclic data telegram for this block.
2.There is NO "Totaliser (TOT)" function block allowed on block position 1, 2, 6, 7, 8 and 9! 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)" – function blocks will be found in the corresponding GSD files.)
3.There is NO "Analog Input (AI)" function block allowed on block position 3, 4 and 5! 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 3, 4 and/or 5.

Profile specific Ident. Number (9741 hex)
Functionality is reduced to the requirements which are mandatory in the PA Profile; e.g. 2 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 ultrasonic 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. 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.

3.3 Electrical connection for PA signal converter
INFORMATION!
The wiring between the device and the PROFIBUS PA bus is independant of polarity.
The signal converter PROFIBUS PA interface will operate only if the additional power supply for the device is connected/available.
For a detailed description of the electrical connections please refer to the standard signal converter handbook. Refer also to the PROFIBUS PA user and installation guideline (Version 2.2, February 2003 PNO order no. 2.092).
