From the "Data Logs" folder, you can open any of the data log files. If you have logged in
with the "write/delete files" privilege (Page 604), you can also delete, rename, and upload
files. The data log files are in comma-separated values (CSV) file format. You can save them
to your computer or open them in Microsoft Excel (default) or another program. Note that if
the PLC program has a data log open, you cannot delete it from the file browser page while it
is open. Also, you cannot upload a data log file if the filename already exists.
Note
Time stamps for data logs
The Web server displays the time stamps for the d
ata logs in either UTC time or PLC local
time depending upon your selection at the top of the page.
