7.11.2 Event logging
The input dialogs of the category
EVENT LOGGING
comprise all settings for logging and outputting events
during the operation of the device:
• Event display,
• time interval (of the logging cycle),
• error table.
Event display:
The event display [1] uses short, single-line entries
specifying date and time to report the events that were
logged during the operation of the device. The entries
are listed in chronological order with the most recent
event at the top position. The list can be displayed but
not edited. If the event display consists of several
pages, the user can browse through the list. The status
indicator [2] indicates which page of the total number
of pages is currently being displayed.
1. To browse forward in the list:
>
Press the C
ONTINUE
key [5].
2. To browse backward in the list:
>
Press the P
REVIOUS
key [3].
3. To exit the display:
>
Press the E
ND
key [4].
>
The system returns to the Event Logger menu.
Changing the logging cycle time:
Due to limited memory resources, the oldest entries
are deleted as new entries are logged. The period from
which the displayed entries originate depends largely
on the selected logging cycle time.
The setting controls the logging cycle in sections of
seconds during which the control loop measured
values are logged during the operation of the device
and displayed by the trend display
(see chap. 7.12‚
pg. 94) .
