Step 1 – Preparing the control system (S7 PLC)
The first step involves the assignment of an IP address to the IO Controller (PLC - S7) and
the preparation of the control for consistent data transmission, see chapter 12.4.4
"Preparing the control system for 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.

Step 2 – Installation of the GSD file
For the subsequent configuration of the IO devices, e.g., MA 248
i
, the corresponding GSD
file must be loaded first.
General information on the GSD file
The term GSD stands for the textual description of a PROFINET-IO device model.
For the description of the more complex PROFINET-IO device model, the XML-based
GSDML (Generic Station Description Markup Language) was introduced.
In the following, the terms "GSD" or "GSD file" always refer to the GSDML-based format.
The GSDML file can support an arbitrary number of languages in one file. Every GSDML file
contains a version of the MA 248
i
device model. This is also reflected in the file name.
You can find the GSD file at
www.leuze.com
.
All data in modules required for operating the MA 248
i
is described in this file. These are
input and output data and device parameters for the functioning of the MA 248
i
and the defi-
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 248
i
is defined via parameter sets. The parameters and 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 248
i
on the PROFINET-IO,
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 248
i
, please refer to the following module descriptions.
