3.6.4
Text Format
Data File Examples – Figs. 3.5 to 3.8
Text format archived data is stored in a comma separated value
(*.csv) format so that it can be imported directly into a standard
spreadsheet, e.g. Microsoft Excel™ and Lotus 1-2-3™. The files
can also be read as an ASCII text file by a text viewer. When
imported into a spreadsheet, the files appear as shown in
Figs. 3.5 to 3.8.
Alternatively, detailed graphical analysis of the data can be
carried out on a PC using the Company's DataManager data
analysis software package.
3.6.5
Text Format
Data File Digital Signatures – Fig. 3.5
A digital signature file is created for each channel data file using
the same filename but with a *.S** extension. The file contains a
unique 'fingerprint' of the contents of the data file that can be
used to prove if the data has been tampered with or corrupted.
Data validation can be carried out on a PC using the Company's
DataManager software package.
3.6.6
Text Format Data Verification and Integrity
When data is saved to the archive media it is checked
automatically to verify that the date value stored on the media
matches exactly the date value stored in the internal memory.
Fig. 3.5 Channel Data File Sample – Text Format
If one of the archive log files becomes full (>64000 entries) a new
file is created with an extension incremented by 1, e.g. a01, e01
etc.
New text format log data files are also created when the daylight
saving period starts or ends.
Files containing log data generated during the daylight saving
period (summertime) have '~DS' appended to the filename.
3.6.3
Text Format Log files
The Alarm Event and Totalizer Logs for each Process Group and
the Audit Log are archived into individual files. The filenames are
formatted as shown in Table 3.4 with the date and the time
indicating the first entry in the file.
