Configuring and Parameterize the Device
9.1
Basics
The device is always configured by a number of parameters. These parameters can be
set by means of a web interface which is provided by the device. Profibus-specific
communication parameters, such as address segments and slave numbers, as well as
all signals to be measured, are part of the parameters and stored in the configuration
files on the device. If required these files (*.csv) can be edited with the help of a text
editor or MS Excel.
Important note
Basically, we recommend configuring the device via the web interface because opera-
tion is safer and easier.
For this reason the description of the configuration files and how to edit them is not part
of this documentation. Further information is available on request.
9.2
Modes of Operation and Data Types
The data to be measured from the Profibus is defined using the GSD data files which
must be registered on the DP Master. The data types for both slaves on the device are
furthermore selected over the web interface by choosing the mode of operation. GSD
file and mode of operation must fit together.
In general, the following data types may be processed:
2 * (32 * 16 bit i 32 binary) in modes 0, 5, 8
2 * (32 bit 32 binary) in modes 1, 6, 9
2 * (28 SIMATIC S7 32 binaries) in modes 3, 7, B
Depending on whether you want to read data from the Profibus master or write data to
it or both the mode switch has to be set appropriately.
For more information see chapter „Setup of Mode and Station Number “, page 48.
The transmission of data is usually managed by message block transmission.
Each DP slave uses one block for data transmission in each direction, i. e. an
ibaBM-DPM-S-64 uses two blocks in total (slave 1 and 2).
The data structure of these blocks for reception (outputs) and transmission (inputs) is
shown in the following for each of the different operation modes.
Please note that the description gives examples for one slave. The description applies
to the second slave as well.
Important note
When connecting a SIMATIC S5 to an ibaBM-DPM-64 via Profibus, e. g. by an IM308C
interface board, you should prevent a data format conflict. Because the data formats of
S5 do not comply with IEEE standard, the S5-data should be converted on S5-side be-
fore being transferred to the Profibus interface!
