Memory usage and application examples

3.2 Memory usage for data logging

In the file browser, you can download the data logs created in the example program. It is not

possible to delete or rename the data logs in the Web server. To delete a data log you either

use the "DataLogDelete" instruction or you format the SIMATIC memory card.

On the DataLogs web page, you can have all the data logs that you created displayed. You

can call and empty the relevant data log file by clicking the icon

Note

Manipulation of the data logs using a card reader

Do not delete or change the data logs using a card reader on the PG/PC. You can copy the

data logs on the SIMATIC memory card, however, using a card reader on the PG/PC.

The recommended medium for viewing, downloading (copying) and deleting data logs is the

file browser of the web server, however. Direct file access via Windows Explorer brings with

it the risk of inadvertent deletion of modification of data logs or system files. This can cause

the files to be damaged or the SIMATIC memory card to become unusable.
