Indications
General
During operation, indications deliver information about operational states. These include:
•
Measured data
•
Power-system data
•
Device supervisions
•
Device functions
•
Function executions during testing and commissioning of the device
In addition, indications give an overview of important fault events after a failure in the network. 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):
•
User-defined log 200 indications
•
Operational log 2000 indications
•
Sequence of events 2000 entries
If the maximum capacity of a log is exhausted, the oldest entries disappear before the newest entries. 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 generated spontaneously via the communication interfaces of the device and through an
external request in the form of a 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
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 forward slash signifies the total number of indications available. The number before the forward
slash indicates the position the selected or displayed indications has in the list. The end of the indication list is
closed with the entry ***END***.
