6.8 Logging

Data recorded in the transmitter's internal memory can be
archived to a removable Secure Digital (SD) card or USB stick.
The transmitter continuously records all data to its internal
memory and keeps track of which data has been archived.
Note. ABB's DataManager software can be used to store
and view data archived from the transmitter.
The amount of time that data remains in the transmitter's
internal memory depends on the sample rate – see Table 6.4.
Sample data is saved to removable media as comma-separated
files.
Configuration files are saved as binary-encoded files. Additional
files can also be archived:

Event log files (these files contain Audit Log, Alarm Log,
Diagnostic Log and Calibration Log data)

Data log files

Configuration files
The transmitter's internal memory supports a maximum of 10
Data Log and Event Log files only and a maximum of 8
Configuration files. Durations for continuous recording are
shown in Table 6.4 (internal storage).

6.8.1 SD card / USB stick

Caution. To avoid potential damage or corruption to data
recorded on an SD card / USB stick, take care when
handling and storing. Do not expose to static electricity,
electrical noise or magnetic fields. When handling the SD
card / USB stick take care not to touch any exposed metal
contacts.
There are two methods of archiving to an SD card / USB stick:

An SD card / USB stick is kept in the transmitter
Data is archived to the SD card / USB stick automatically
at set intervals. Archiving continues until the SD card /
USB stick full; archiving then stops. To ensure all required
data is archived successfully, the SD card / USB stick
should be swapped periodically for an empty one.
Note. It is not advisable to leave a USB stick in the
transmitter permanently.
It is advisable to back-up critical data stored on an SD
card / USB stick regularly. The transmitter's internal
memory provides a buffer for the most recent data only
so, if data stored on an SD / USB stick card is lost, it can
be re-archived.

Data is copied to an SD card / USB stick when
required
When a SD card / USB stick is inserted into the
transmitter, the media status can be set to Online causing
unarchived data to be copied to the media – see Section
7, page 39 / Media Card menu level.
