in the download directory of the PLC.
Filename: Name of the file which should save the alarm events (e.g. "alarmlog").
Automatically a file will be created which gets the name defined here plus an
attached digit and which has the extension ".alm". The digit indicates the version of
the log-file. The first file gets a "0"; each further file, which will be created according to
the defined File change event, will be numbered with 1, 2 etc. (Examples:
"alarmlog0.alm", "alarmlog1.alm).
File change event: Define here the event which will cause the creation of a new file for
alarm-saving. Possible entries: Never, after one Hour, after one Day, after one Week,
after one Month, at a rising edge of the variable defined in field Triggervariable, when
the number of records in the file as defined in Number of records gets exceeded.
