When the screen restarts after the power failure, using this option can make the latest 1024
pieces of historical event information before the power failure resumed to be displayed on the
Event Display component.
Exports the historical event information in CSV format to the external storage devices. The
path for storing this CSV file is "/event/subdirectory name/file name".
Makes the data sampling time accurate to the millisecond and records it into the CSV file.
Sets the subdirectory name of the external memory where the CSV file will be stored. The
users can modify it by themselves, and the default name is "Event".
Daily File Stores the historical event information by day and records them into
the CSV file named in "yyyy mmdd" format.
Single File Stores the historical event information by the piece and records them
into the CSV file with the name of "Subdirectory Name".
Provides a kind of buffer storage mechanism. When the data written into the USB disk
amounts to the set size of the buffers, the writing is only performed once. "Default" means no
buffering, i.e. the writing operation will immediately be performed once the data is generated.
Sets the upper limit for the storage amount with the unit of "Day" for Daily File and "Piece" for
Single File. When the [Daily File] is selected, the file will be named in "yyyy mmdd" form and
the Max Storage is the upper limits of the number of CSV files in this path; if the Max Storage
is exceeded, the oldest file will be deleted. If the [Single File] is selected, the file will be named
in "Subdirectory Name" form, the Max Storage is the upper limit of the records stored in this
file; if the Max Storage is reached, the storage will not be continued. (yyyymmdd refers to the
execution date.)
