Event Log
The event log provides a historical record of event occurrences detected by the DGC-2020. It is saved in
nonvolatile memory so that is will not be affected if power is removed. Thirty event records are retained
and each record contains a time stamp of the first and last event occurrence, and the number of
occurrences for each event. In addition, each record contains details of the time, date, and engine hours
for the most recent 30 occurrences of the event. The number of occurrences stops incrementing at 99. If
an event occurs which is of a type that differs from those in the 30 records in memory, the record that has
the oldest “last” event occurrence is removed from the log, and the new category takes its place. Since 30
event records with up to 99 occurrences each are retained in memory, a history of nearly 3,000 specific
events are retained in the DGC-2020. Detailed occurrence information is retained for the most recent 30
occurrences of each event record, and there are 30 event records; thus the time, date and engine hours
details for up to 900 specific event occurrences is retained in the event log.
The user can download the event log data into BESTCOMSPlus for viewing, and then save the event logs
as files. The Options button is used to save the entire event log to a file, or to save the list to the computer
clipboard making it available for insertion into other software applications. It is possible to copy a portion
of the log to the computer clipboard by selecting the desired portion with the mouse then using the
Options->Copy Selection feature. The Download button refreshes the event log list by performing a fresh
download of the list from the DGC-2020. The Clear button gives the user the option of clearing selected or
all event logs. Refer to Figure 4-103.
