GSD Selection Algorithm
If two or more matching GSD-files are found, the first one found should be
selected. The other compatible files should be stored so that the user can select
one of them instead. If the user selects another GSD-file, the PROFIBUS Master
Configuration window will run through the Module Selection Algorithm (described
below) again.
Module Selection Algorithm
The algorithm used to find modules in the GSD based on the Identifier byte(s) is
as follows:
Select the module that matches the largest number of Identifier bytes. If the GSD
contains two or more modules with the exact set of Identifier bytes, use the first
module found.
Example:
If a slave responds with identifier bytes: 0x11, 0x21, 0x31 and that the associated
GSD-file contains five modules: “A” = 0x11, “B” = 0x21, “C” = 0x31, “AB” = 0x11,
0x21 and “BC” = 0x21, 0x31. The PROFIBUS Master Configuration window will
then select modules "AB" and "C".
Note: If no matching module is found in the GSD, The PROFIBUS Master Configuration window
will display the identifier byte(s) instead.
Network scan window
The information extracted from the GSD-file(s) will be displayed in the Network
scan window.
Note: only slaves are shown here, possible Masters connected to the network will not be listed
here!
Select
In this column all found slaves will be marked as selected by default, except for
slaves with the special address 126 (refer to the next section that describes the
Address column). Only selected slaves will be added to the PROFIBUS Master
Configuration when the ADOPT SELECTED SLAVES button is clicked.
