4.4.1 General information on the DP master
PROFIBUS devices have different performance features.
The characteristic features of the slaves are summarized in a master
device file (GSD) so that all of the master systems can correctly ad-
dress the DP slave.
The features for the various master systems are summarized in a stan-
dardized master device file (GSD).
A master device (GSD file) describes the features of a DP slave in a
precisely defined, uniform format in accordance with EN 50 170, Vol-
ume 2, PROFIBUS.
GSD files are saved in the directory ”\GSD”.
The associated bitmaps are saved in the directory ”\Bitmaps”.
The master device file (GSD) for the ”DP slave POSMO A” is available
as ASCII file as follows:
File name: SIEM8054.GSD

tents, contain closed information which cannot be accommodated using
a byte, word or double–word structure.
For consistent data transfer, you require the SFC 14 and SFC 15
