8 Exporting System Data
8.1 Export Options
The instantaneous values and the parameters of the devices in the system can be saved, displayed
and prepared for further processing by the Cluster Controller. The system data can be saved to the
internal memory of the Cluster Controller and to an external storage medium. The storage capacity
of the internal memory is limited. If the free storage capacity of the internal memory is 10% or
below, the older system data will be deleted until a free storage capacity of 20% is reached.
Therefore, save the system data to an external storage medium at regular intervals. You have the
following options for exporting the system data:
Option Explanation
Export to USB data carrier The system data is exported to a USB data carrier that is con-
nected to the Cluster Controller (see Section 8.4, page 51).
Export to integrated FTP server The system data is exported to the FTP server integrated in the
Cluster Controller (see Section 8.5, page 52).
You can access the exported system data directly via the inte-
grated FTP server. The integrated FTP server is protected via the
system password of the respective user group.
Export to external FTP server The system data is exported to an external FTP server via FTP
push function (see Section 8.6, page 53).
Export to Sunny Portal The system data is sent to the Sunny Portal Internet portal at a
configurable time interval (see Section 11.2, page 61).
8.2 Export Formats
8.2.1 CSV Format
If the CSV format is selected, the Cluster Controller creates a CSV file for each day and saves the
collected system data to this file every five minutes. Individual data records are always separated
by a semicolon in the CSV file. The decimal separator and the time format within the CSV file
depend on the country settings of the Cluster Controller (see Section 6.3, page 41).
Directory path and structure of the file name
Directory path: .../CSV/[YYYY]/[MM]/
File name structure: [YYYYMMDD].csv
Example: daily report file from 2012-10-15
