Make a copy of the data log files and put the copies on a local drive of your PC. Then, you
can use Excel to open a local copy of a *.csv file and not the original file that is stored on the
memory card.
NOTICE
You can copy, but do not modify or delete data log files on a S7-1200 memory card using a
PC card reader
The standard Web server File Browser page is the recommended tool for viewing,
downloading (copying), and deleting data log files.
Direct browsing of the memory card file system by the Windows Explorer has the risk that
you can accidentally delete/modify data log or other system files which can corrupt a file or
make the memory card unusable.
Viewing data logs from a Web browser
Even if you do not use the Web server feature, you can view data logs directly from a Web
browser such as Internet Explorer or Mozilla Firefox. Simply enter the following text into the
address bar of your browser using the IP address of your CPU and the actual name of the
data log file you provided in STEP 7 instead of "MyDataLog":
http://192.168.0.1/FileBrowser/Download?Path=/DataLogs/MyDataLog.csv
The fixed addresses of data log files also make it possible to access them through third party
file collection tools.

Limit to the size of data log files
Data log files share PLC load memory space with the program, program data, configuration
data, user-defined Web pages, and PLC system data. A large program using internal load
memory requires a large amount of load memory. There may be insufficient free space for
data log files. In this case, you can use a "Program card" to increase the size of load
memory. S7-1200 CPUs can use either internal or external load memory, but not both at
once.
Refer to the memory card chapter for details about how to create a "Program" card
(Page 130).
