Transmission Statistics
In 7SD610 the protection communication is registered in statistics. The transmission times of the information
between the devices via interfaces (send and receive) are measured continuously. The values are kept stored
in the statistics folder. The availability of the transmission media is also reported. The availability is indicated in
% min and % h. This enables an evaluation of the transmission quality.
If GPS synchronization is configured, the transmission times for each direction and each protection data inter-
face are regularly measured and indicated as long as GPS synchronization is intact.
