Indications

General

8.4.1
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
If the maximum capacity of the user-defined log or of the operational is exhausted, the oldest entries disap-
pear 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 issued via the signal Fault log is full. 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
demand via general interrogation. In DIGSI 5 indications can be tracked spontaneously in online operation in a
special indication window. Indications can be made accessible to higher-level control systems through
mapping on various communication protocols.
NOTE
i i
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.
