12.3.1 Step 1 – Preparing the control system (S7 PLC)
In the first step, the control is prepared for consistent data transmission.
During programming the control system must be prepared for consistent data transmission.
This varies from control system to control system. The following possibilities are available
for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be
integrated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
Notice!
If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 +
service pack 5 (V5.4+SP5) or higher is used.
12.3.2 Step 2 – Installation of the GSD file
For the subsequent configuration of the PROFIBUS devices, e.g., MA 204i, the
corresponding GSD file must be loaded first.
General information on the GSD file
The term GSD stands for the textual description of a PROFIBUS device model.
The GSD file can support an arbitrary number of languages in one file. Every GSD file
contains a version of the MA
You can find the GSD file at

readers.
All data in modules required for operating the MA
input and output data and device parameters for the functioning of the MA
nition of the control and status bits.
If parameters are changed, e.g., in the project tool, these changes are stored on the PLC
side in the project, not in the GSD file. The GSD file is a certified and integral part of the
device and must not be changed manually. The file is not changed by the system either.
The functionality of the MA
their functions are structured in the GSD file using module. A user-specific configuration
tool is used during PLC program creation to integrate the required modules and configure
them appropriately for their respective use. During operation of the MA
PROFIBUS DP, all parameters are set to default values. If these parameters are not changed
by the user, the device functions with the default settings delivered by Leuze electronic.
For the default settings of the MA 204i, please refer to the following module descriptions.
