Downloading a Project that contains a Data Log Configuration
You must download a project that contains a data log configuration to an S7-200 CPU before the
data log can be used. If a project has a data log configuration, then the download window has the
Data Log Configurations option checked by default.
Tip
When you download a project that contains data log configurations, any data log records
currently stored on the memory cartridge will be lost.
To download a project that contains data log configurations, follow the steps below. See
Figure 14-8.
1. Select File > Download.
2. In the dialog, under Options,
ensure that the Data Log
Configuration box is checked.

Using the S7-200 Explorer
The S7-200 Explorer is the application used to read a data log from the memory cartridge, and
then store the data log in a Comma separated Values (CSV) file.
Each time a data log is read, a new file is created. This file is saved in the Data Log directory. The
file name is formatted as follows: PLC Address, data log name, date, and time.
You can choose whether the application associated with the CSV extension is automatically
launched when the data log has successfully been read. This selection is available from the right
mouse menu of the data log file.
The Data Log directory will be below the directory specified during installation. The default
installation directory is c:\program files\siemens\Microsystems (if STEP 7 is not installed). The
default installation is c:\siemens\Microsystems (if STEP 7 is installed).

S7-200 Network folder should
