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.

These files are also available from the download area of the BX9000 at the Beckhoff website: www.beckhoff.com/BX3100

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.
