72 MA 248i Leuze electronic
12.4.1 Modular structure of the parameter
The PROFINET-IO functionality of the device is defined via parameter sets which are clus-
tered in modules. The modules are included in a XML-based GSD file, which is supplied as
an integral part of the device. By using a user-specific project tool, such as, e.g., Simatic
Manager for the Siemens programmable logic control, the required modules are integrated
into a project during commissioning and its settings and parameters are adjusted accord-
ingly. These modules are provided by the GSD file.
Notice!
All input and output modules described in this documentation are described from the con-
troller's perspective:
- Input data arrives at the controller.
- Output data is sent out by the controller.
Detailed information on how to prepare the control and the GSD file may be found in chapter
"Configuration steps for a Siemens Simatic S7 control" on page 65.
For the default settings of the MA 248i, please refer to the following module descriptions.
Notice!
Please note that the set data is overwritten by the PLC!
Some controls make available a so-called "universal module". This module must not be
activated for the MA 248i!
From the perspective of the device, a distinction is made between PROFINET-IO parameters
and internal parameters. PROFINET-IO parameters are all parameters that can be changed
via the PROFINET-IO and are described in the following modules. Internal parameters, on
the other hand, can only be changed via a service interface and retain their value even
following a PROFINET-IO configuration.
During the configuration phase, the MA 248i receives parameter telegrams from the
controller (master). Before this is evaluated and the respective parameter values are set, all
PROFINET-IO parameters are reset to default values. This ensures that the parameters of
modules that are not selected are set to the default values.
