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.
