8.5 Logs

General

8.5.1
Indications are saved in logs inside the device and are available for later analyses. Different logs allow catego-
rization of indication logging based on operating states (for example, operational and fault logs) and based on
fields of application.

Log Management
Logs have a ring structure and are automatically managed. If the maximum capacity of a log is exhausted, the
oldest entries disappear before the newest entries. If the maximum capacity of the fault or ground-fault log is
reached, the number of the last fault is generated via the signal Fault log is full. You can route this signal in
the information routing. If indications in the information routing of DIGSI 5 are routed to a log, then they are
also saved. During a supply-voltage failure, recorded data are securely held by means of battery buffering or
storage in the flash memory. You can read and analyze the log from the device with DIGSI 5. The device
display and the navigation allow you to read and evaluate the logs on site using keys.
Configurability of Logs
The indication capacity to be recorded in configurable logs (for example, ground-fault log) is laid down in
columns of the information routing (matrix) of DIGSI 5 specifically defined for this purpose.
Procedure
To reach the information routing of your SIPROTEC 5 device, use the project-tree window. Access is only
through the project:
•
Open the information routing.
Project → Device → Information routing
•
Select the appropriate routing column.
Destination → Logs → Column Ground-fault log (G)
The routing of the selected indication is done via right click.
•
Select one of the options in the list box shown:
– Routed (X)
– Unrouted
