Pending diagnostic events

The Diagnostics menu allows the user to view the current diagnostic event and the
previous diagnostic event separately.
To call up the measures to rectify a diagnostic event:
• Via local display →  134
• Via web browser →  135
• Via "FieldCare" operating tool →  137
• Via "DeviceCare" operating tool →  137
Other pending diagnostic events can be displayed in the Diagnostic list submenu
→  142.
