9.1.8 Configuration of the Decentralized Archive
• Menu Home | Settings
The decentralized archive serves for the local storage of events of a substation, and - when-
ever necessary - for the transmission to the control system. By means of that, it is for instance
possible to recover the archive of a control system after a communication fault.
The configuration of the decentralized archive resides in the directory tree under
SICAM A8000 CP-80xx | Master module | Decentral archiving
(the checkbox SHOW ALL PARAMETERS must be activated).
All the data points that are recorded in the event list are simultaneously recorded in the
decentral archive. The definition thereto resides in the signal parameterization (see 9.1.11.2.1,
Configurable Logging and Display of Signal States).
The data points to be recorded are archived chronologically during operation. The record hap-
pens for the following categories:
• Commands upon status change
• Binary information items upon status change
• Measured values according to parameter Recording grid for measured values
You find the detailed information on the settings in the manual SICAM RTUs Common Func-
tions System and Basic System Elements, chapter "Telecontrol", section "Decentralized Ar-
chiving".
Note
The data records of the decentralized archive are registered in configurable files. The files are stored on
the SD card. The record of data points is therefore only possible with equipped SD card.
Memory Configuration Archive
With the help of this parameter it is possible to select the configuration of the archive stored
on the SD card. You may select this parameter referring to your field of application. The
smaller the bandwidth of your communication line is the smaller the separated files should be.
