When a ring buffer is activated a check is made that there is enough free space on the
CompactFlash card or in the internal memory to log the data with the defined observation
rate and data interval. This required space is reserved, so that it cannot be used by other
applications such as logging the standard set of raw data.
Example: For a ring buffer with a time interval of 1 h, the last 1 h of stored data is always
available. Data older than 1 h is automatically overwritten by the data currently being logged.
Number of files:
Depends on the data interval specified. It is automatically determined.
Example: An interval of 1 h consists of six files each of ten minutes
length and a seventh file which is currently logged data to when the
ring buffer is active.
Type of files:
Measurement database files.
File name:
All files for one ring buffer share the same file name.
File extension:
The file extensions for the files of one ring buffer differ and increment.
Directory:
