‘Erase Logs’ deletes all system event logs.
Do not erase any logs unless you are sure they are no longer necessary. For example:
• The logs are too big to collect. Erase the logs, leave the system to run its diagnostic routines
(24 hours), then collect the logs to inspect current problems.
• Collect the logs once a month for an archive, and erase the logs after each collection to keep
them small.
The default option is to erase all logs in the system. This includes the main processor current and
backup logs (in both processors if two are fitted), all communication interface logs, and all I/O module
logs.
If you de-select ‘Erase all logs in system’, you can choose which module logs to erase. You can select
one I/O module from a drop-down list.
The Analysis Tool will collect the first 90 lines of each I/O module log before erasing it. It checks these
lines for manufacturing test entries, and puts these test entries back into the log after erasing it. This
assists with module diagnosis and repair. Note that Dumptrux does not preserve these test entries and
should no longer be used for erasing logs.
‘Analyse Data’ passes the collected data to the analysing side of the program, which will prepare
reports. Choose this option when you have collected all the data you want, and you want to analyse it.
After this, the program behaves exactly as if you had opened an existing file through File | Open. You
can still go back online however, using menu option Online | Terminal. The analysis side of the tool is
described later.
