General Information

The BPS 34 with MS 34 103/MS 34 105 was developed as a Profibus device. The function-
ality of the device is defined via parameter sets which are clustered in modules. These
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 programmable logic
control by Siemens, 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.
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.
7.1.1

GSD File

The GSD file can be found on the disc supplied with this documentation.
This file stores all the data required for the operation of the BPS 34. This data consists of
device parameters required for operation of the BPS 34, Profibus operation parameters, and
the definition of the control and status bits. If parameters are changed in the project, for
example, these changes are stored in the project, not in the GSD file.
The GSD file is a certified part of the device and must not be changed manually. The file is
not changed by the system either.
7.2

Structure of the project modules

In the current version, a total of 17 modules are available for use. The modules may be
included into the project according to requirements and application.
The modules fall into the following categories:
• Parameter module for the scanner configuration
• Status or control modules that influence the input and output data.
• Modules that may include both parameters and control or status information.
The category of each module is marked with a cross in the overview.
Notice!
At least one module must be activated to permit operation of the device at the Profibus DP.
