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 248
i
, 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 248
i
!
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 248
i
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.
