When the download is completed, the PROFIBUS Master Configuration window

possible to initialize the Master even if the database does not contain any slaves.

issue the following mailboxes in order to gather information about the connected
slaves:
1 1. Send FB_APPL_GET_LIVE_LIST in order to detect connected slaves,
2 2. Send FB_APPL_GET_SLAVE_DIAG (external request) to all devices
identified as slaves according to the Live list.

according to the Live list.
