Archive file types

All files created by the transmitter are assigned filenames
automatically. Each type of file is assigned a different file
extension. Archive files are created as text format,
comma-separated data files.
The file type and extension for Data text files is '.D00'
<ddmmmyy><hhmmss><instrument tag>.D00
The file type and extension for Event log files (containing
historical entries from the Audit, Calibration, Diagnostic
and Alarm logs is '.A00'.
<ddmmmyy><hhmmss><instrument tag>.A00
NOTICE
• The 'instrument tag' is set in the Device Setup level (see
page 31) when the user has access at Advanced level –
see page 33.
• The time and date are formatted according to the format
selected in the Display level (Date & Time) – see page
39.
• The transmitter's internal clock can be configured to
adjust automatically at the start and end of Daylight
Saving periods – see page 39.
Configuration filenames are preset as Config1 to Config8. The
configuration file type and extension is '.CFG'.

Data files

Text format archived data is stored in a comma-separated value
(CSV) format and can be imported directly into a standard
spreadsheet, for example, Microsoft® Excel®.
Alternatively, detailed graphical analysis of the data can be
performed on a PC using ABB's DataManager Pro data analysis
software.
New data files are created if:
• the transmitter configuration is changed
• one of the current files exceeds the maximum permissible
size (a new file is created at 00:00:00 a.m. on the following
day) – data is logged into the existing file continuously
until the new file is created
• the daylight saving period starts or ends
• working files cannot be found/are corrupted
• the date and/or time is changed
The filename is formatted as follows:
• Data logs: <ddmmmyy><hhmmss><instrument tag>.D00

Log files

The Alarm Event, Calibration, Diagnostic and Audit logs are
archived into the same file. The filenames are formatted as
follows:
• Event logs: <ddmmmyy><hhmmss><instrument tag>.A00
