Commissioning and configuration
12.5.4 Automatic baud rate detection
The PROFIBUS implementation of the MA
MA
204i
uses this function and offers no possibility for manual or permanent adjustment.
The following baud rates are supported:
Baud rate kBit/
s
Automatic baud rate detection is indicated in the device master file of the MA 204i:
Auto_Baud_supp = 1
12.5.5 Modular structure of the parameter
The PROFIBUS DP functionality of the device is defined via parameter sets which are clus-
tered in modules. The modules are included in a 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 accordingly. These
modules are provided by the GSD file.
Notice!
All input and output modules described in this documentation are described from the
controller'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 60.
For the default settings of the MA 204i, 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 204i!
From the perspective of the device, a distinction is made between PROFIBUS parameters
and internal parameters. PROFIBUS parameters are all parameters that can be changed via
the PROFIBUS 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
PROFIBUS configuration.
During the configuration phase, the MA
IO Controller (master). Before this is evaluated and the respective parameter values are set,
all PROFIBUS parameters are reset to default values. This ensures that the parameters of
modules that are not selected are set to the default values.
