3.6.1 Text Format Channel Data Files

Text format channel data files can be configured to contain data
gathered over a predefined period of time using the 'New File
Interval' setting – see Table 3.3.
New File Interval
Hourly <hour> <day, month, year>* <filename tag>
Daily <day, month, year>* <filename tag>
Monthly <month, year>* <filename tag>
None <filename tag>
* Formatted according to the date format set in Common
Configuration – see Section 4.4.3, page 54
Table 3.3 New Text File Intervals
Note. The 'New File Interval' is set in the Configuration level
– see Section 4.5.6, page 75.
In addition to new channel data files being created according to
the New File Interval selection, they are also created in the
following circumstances if automatic update is enabled and the
media is on-line or if a manually triggered update is in progress:
The instrument's power is lost then restored.
The instrument is taken offline and the archive media
removed, replaced or refitted.
The instrument's configuration is changed.
One of the current files exceeds the maximum permissible
size.
When the daylight saving period starts or ends.
Note. The instrument's internal clock can be configured to
adjust automatically at the start and end of Daylight Saving
Time (Summertime) periods – see Section 4.4.3, page 54.
When one of these conditions occurs, new channel data files are
created for each enabled group and the file extension index on
each new file is incremented by one from the previous file.
Example – if the original file had an extension of .D00,
after one of the above events a new file will be created
with the same filename but an extension of .D01.
IM/SM2000 Issue 11
Filename
Files containing data generated during the daylight saving period
(summertime) have '~DS' appended to the filename.
Example 1 – Start of daylight saving period:
A daily file is started at 00:00:00 on 30th March 2003 –
filename: 30Mar03ProcessGroup1.D00.
Summertime starts at 2:00am on 30th March 2003.
The clock changes automatically to 3:00am.
The existing file is closed and a new file is created –
filename: 30Mar03ProcessGroup1~DS.D00.
The file '30Mar03ProcessGroup1.D00' contains data
generated from 00:00:00 to 01:59:59 (before summertime
starts).
The file '30Mar03ProcessGroup1~DS.D00' contains data
generated from 03:00:00 (after summertime starts).
Example 2 – End of daylight saving period:
A daily file is started at 00:00:00 on 26th October 2003 –
filename: 26Oct03ProcessGroup1~DS.D00
Summertime ends at 3:00am on 26th October 2003.
The clock changes automatically to 2:00am.
The existing file is closed and a new file is created –
filename: 26Oct03ProcessGroup1.D00
The file '26Oct03ProcessGroup1~DS.D00' contains data
generated from 00:00:00 to 02:59:59 (before summertime
ends).
The file '26Oct03ProcessGroup1.D00' contains data
