Basic Device File (GSD)
All field devices with PROFIBUS slave interface are described via the GSD file. The BX3100 is a PROFIBUS
DP slave. For data exchange, the GSD file has to be inserted in the master configuration tool. The maximum
length of input and output data 244 bytes in each direction.

The GSD file can describe the following data types:
Variable
Length
Integer 8
1 bytes
UnInteger 8
1 bytes
Integer 16
2 bytes
UnInteger 16
2 bytes
Integer 32
4 bytes
UnInteger 32
4 bytes
Float 32
4 bytes
Data types that are not listed, e.g. BOOL variables, can be described via the length. For this purpose, the
GSD file includes configuration data starting with a byte and ending with 64 words.

DEFAULT CONFIG
DEFAULT-CONFIG contains the PROFIBUS data from the address %IB1000 input and %QB1000. The data
length depends on the number of configured PROFIBUS data. A maximum of 244 bytes of input data and
244 bytes of output data can be parameterized. No further settings are required for this configuration type.
