Indications
General
During operation, indications deliver information about operational states. These include:
•
Measured data
•
Power-system data
•
Device supervisions
•
Device functions
•
Function procedures during testing and commissioning of the device
In addition, indications give an overview of important fault events after a failure in the system. All indications
are furnished with a time stamp at the time of their occurrence.
Indications are saved in logs inside the device and are available for later analyses. The following number of
indications are saved at least in the respective buffer (depending on the scope of the indications):
•
Ground-fault log 100 indications
•
Fault log 1000 indications
•
User-defined log 200 indications
•
Operational log 2000 indications
•
Motor-starting log 200 indications
If the maximum capacity of the user-defined log or of the operational log is exhausted, the oldest entries
disappear before the newest entries. If the maximum capacity of the fault log or of the ground-fault log is
reached, the number of the last fault is output 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 navigation using keys allow you to read and analyze the logs on site.
Indications can be output spontaneously via the communication interfaces of the device and through external
request via general interrogation. In DIGSI 5, indications can be tracked spontaneously during online mode in
a special indication window. Indications can be made accessible to higher-level control systems through
mapping on various communication protocols.

NOTE
All indications are assigned to certain device functions. The text of each indication contains the corre-
sponding function designation. You will find explanations of the meaning of indications in the corre-
sponding device functions. However, you can also define indications yourself and group them into your
own function blocks. These can be set by binary inputs or CFC logic.
Reading Indications
To read the indications of your SIPROTEC 5 device you can use the on-site operation panel of the device or a PC
on which you have installed DIGSI 5. The subsequent section describes the general procedure.
Reading Indications on the On-Site Operation Panel
Procedure
The menus of the logs begin with a header and 2 numbers at the top right corner of the display. The number
after the slash signifies the number of indications that are available. The number before the slash indicates
how many indications have just been selected or shown. The end of the indication list is closed with the entry
