12.8 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.
