When a network scan is initiated, the
PROFIBUS Master Configuration
window
will download the Master bus parameters (baudrate etc.).
When the download is completed, the
PROFIBUS Master Configuration
window
will initialize the Master to operate as a

. In this mode it is
possible to initialize the Master even if the database does not contain any slaves.

window will
issue the following mailboxes in order to gather information about the connected
slaves:
1
