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47).

Export to integrated FTP server The system data is exported to the FTP server integrated in the

ClusterController (see Section8.5, page48).

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49).

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57).

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37).

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

.../CSV/2012/10/20121015.csv
