AN-T80020 Diagnostics Procedure
Issue 12 Feb 11 AN-T80020 24
Each event includes a timestamp, which is calculated from a millisecond count in the log. If the
timestamp can't be determined, it is shown as time since startup or the beginning of the log. The logs
contain no information on the year, so the Analysis Tool makes a best guess based on other data. For
this reason, the year may be wrong.
Entries are categorised and coloured in a similar way to the graphical system view – see page 22.
The Severity shows the Analysis Tool’s category for the event:
Info Information: normal operation (coloured white)
Fault? Possible Fault: requires further investigation (coloured amber)
FAULT Definite Fault: the module needs repair or fault in configuration (coloured orange)
ALERT Critical Alerts: report to ICS Triplex via [email protected] (coloured red)
These categories are often revised, and so is the advice on each type of fault.
You can filter this data using the menu option View | I/O Log Options.
• You can see only recent events by selecting Only from and choosing a date.
• You can chose to see only important categories by selecting Only at/above and choosing a
level. Events at this category or higher will be shown.
To see your new choice of data, click OK and open the log report again.
