Diagnostic behavior
Warning
1)
Diagnostic behavior can be changed. This causes the overall status of the measured variable to change.
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 "FieldCare" operating tool → 170
• Via "DeviceCare" operating tool → 170
Other pending diagnostic events can be displayed in the
Diagnostic list
submenu
