Test Mode And Influence Of Indications On Substation Automation Technology - Siemens SIPROTEC 5 Operation Manual

Operation in the Operating State
8.4 Indications
Acknowledgment of Stored Indications via Binary Inputs
Acknowledgment via entry >LED Reset
Acknowledgment via binary input >LED-Reset brings about the activation of all LEDs (LED test) and, in case of
dropout of signal, the resetting of all stored indications. Stored LEDs, output contacts and spontaneous fault
displays are reset.
Acknowledgment of Stored Indications with DIGSI 5
You can acknowledge stored indications via DIGSI 5 in online mode. For this, go to the project tree.

•
Click the LED reset button.
•
Enter the confirmation ID.
•
Confirm the process with OK.
Stored LEDs, output contacts and spontaneous fault displays are reset on the assigned device.
Acknowledgment of Stored Indications via Log
Initiation of acknowledgment of stored indications can also occur through communication via a connected
substation automation technology. This can occur in conformance to standards (IEC 61850, IEC 60870-5-103)
or via configuration (mapping) of the LED reset input signal for any protocol. Stored LEDs, output contacts,
and spontaneous fault displays are reset.
NOTE

The acknowledgment of stored indications then leads to the resetting of configured LEDs and output
contacts, as long as these active unstored indications are not present in parallel. That is, indications config-
ured as unstored are not affected by the acknowledgment process.

Test Mode and Influence of Indications on Substation Automation Technology

8.4.10
If the test mode of the device or of individual functions is switched on, the SIPROTEC 5 device marks indica-
tions sent to substation automation technology station control system with an additional test bit. This test bit
makes it possible to determine that an indication was set during a test. Necessary reactions in normal opera-
tion on the basis of an indication can thus be suppressed.
