The ABB GSD file (Ident No. 3402) is divided into 2 sections:
—
General specifications
Identification of the device, together with hardware and
software versions, baud rates supported and the possible
time intervals for monitoring times.
—
DP Slave-related specifications
Information about the user parameter block for
device-specific configuration and modules containing
details of the input and output data that can be exchanged
cyclically with a PROFIBUS master.
The Navigator AWT540 GSD file (ABB_3402.gsd) is available
for download from the ABB website at: www.abb.com/fieldbus
(follow the link for PROFIBUS DP field devices).

PROFIBUS slot /
index
PROFIBUS commands must include
length (in bytes) as well as slot / index.
This is so that multiple values from the
same slot (except strings) can be read /
written in a single transaction (up to the
maximum of 240 bytes). The length must
be a multiple of the 'Bytes value for the
required slot.
The index specifies the starting index for
the values returned. The starting index
plus the number of bytes must not go
beyond the end of the table. Strings must
also specify the correct length in bytes but
only single strings can be accessed in one
transaction.
