3.2.4 Decentralized
Archive
In case of a communication fault, occurring events can be recorded in a decentralized archive.
After elimination of the fault the superior control system can demand the archive of the re-
spective target system. By means of this function, a possible data loss will be prevented .
•
Reconstruction of all process-relevant data during a communication fault
•
Transmission of the archive to the control system
─

•
Configuration acc. to IEC 60870-5-101/104 (point-to-point, multi-point traffic, dial-up traffic,
Ethernet), also multi-hierarchical configurations possible
•
Also multi-hierarchical configurations are possible
•
Reading of the archive via SICAM TOOLBOX II possible
•
