7.5.3 Text Format Log Files (Audit and Alarm Log)

Alarm Event logs for each process group and the Audit log are
archived into individual files.
The filenames are formatted as shown in Table 7.6.
Log File
<hour min> <day, mm, yy>
Alarm Event
<process group tag>.e00
<hour min> <day, mm, yy>
Audit Log
<instrument tag>.a00
Table 7.6 Text Format Log File Format
If one of the archive log files becomes full (>64000 entries) a new
file is created with an extension incremented by 1, for example:
a01, e01.
New text format log data files are also created when the daylight
saving period starts.

7.5.4 Daylight Saving

Files containing data generated during the daylight saving period
have '~DS' appended to the filename.

7.5.5 Text Format Data Verification and Integrity

When text format data is saved to the archive media it is
checked automatically to verify that the data stored on the
media matches exactly what is stored in the internal memory.

7.6 Binary Format Data Files

Binary format archived data is stored in a secure binary encoded
format. A separate file is created for each recording channel.
The log data is stored in an encrypted text format.
The files can be read on a PC using ABB's DataManager Pro
data analysis software package.

7.6.1 Binary Format Data Filenames

When the 'Archive file format' parameter is set to 'Binary
format', the 'New File Interval' parameters (see Section 6.6.4,
page 40) are disabled and binary format filenames are created
with the content – see Table 7.7.
