Displaying the log file

Loggable data that was logged when the action log function was active are displayed in the
"Action Log File" window.
The log is output in English and includes the following columns:
● Date
● Time
● Affected components
● Event ID
Storage location
If the action log is activated, a file for the current log (actual_actionlog.com) is stored in the
data tree of the system data in directory HMI Data / Logs / Action logs.
Activating the crash log file via operating area
The crash log (actual_crashlog.com) is a backup file of the current log when a critical event
occurs (for example, emergency stop alarm). This file is generated if the entry "Save log as
file on alarm" is activated in the settings.
It is then no longer stored in the ring buffer of the action log and can no longer be overwritten
with new entries.
The entries in the crash log file are only overwritten when yet another critical events occurs.
