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
A
DOPT SELECTED SLAVES
button is clicked.
Address
In this column the node address of the slaves will be displayed. Found slaves
should be listed in ascending order according to their node addresses.
