Send parameter data is comprised of a string of octets (1–32) that

contain 244 bytes of data:

• octets 1–7 contain data specific to the:

– PROFIBUS standard

– defaults contained in the database (GSD) file

• octets 8–32 are user configurable and contain user parameter

data. User parameter data consists of these formats:

– auto configure

– condensed

– full

The following illustration shows the structure of the send parameter

data table.
