Method 2: Acknowledgement via LED reset
•
An LED reset (device) causes the reset of all stored LEDs and binary output contacts of the device and also
to the confirmation of all fault displays stored in the display.
You can find more details on the topic of LED reset in chapter 3.1.9 Stored Indications in the SIPROTEC 5
Device
Stored Indications in the SIPROTEC 5 Device
In your SIPROTEC 5 device, you can also configure indications as stored. This type of configuration can be
used for LEDs as well as for output contacts. The configured output (LED or contact) is activated until it is
acknowledged. Acknowledgment occurs via:
•
On-site operation panel
•
DIGSI 5
•
Binary input
•
Protocol of substation automation technology
Configuration of Stored Indications with DIGSI 5
In the Information Routing of each device set up in DIGSI 5, you can route binary signals, among others, to
LEDs and output contacts.
•
To do this, proceed in the project tree to:
Project → Device → Information routing
•
Right-click the routing field of your binary indication in the desired LED or binary output column in the
routing range of the targets.
You are offered the following options:
Table 3-7
Overview of Routing Options
Routing Options LEDs BOs BIs Description
H (active) X The signal is routed as active with voltage.
L (active) X The signal is routed as active without voltage.
U (unlatched) X X The signal is routed as unlatched. Activation and reset of
the output (LED, BA) occurs automatically via the binary-
signal value.
L (latched) X X The binary signal is latched when the output (LED) is acti-
vated. To reset, a targeted confirmation must occur.
NT (conditioned latching) X Fault indications are stored during control of the output
(LED) as a function of parameter (_:91:139) Fault-
display.
•
When the fault gets terminated via a trip command
from the device, the status of a fault indication
remains as latched with the setting option with
trip. In case of pickup dropout without trip
command the status is displayed before the fault is
restored.
•
With the setting option with pickup the actual fault
indication status of a pickup gets stored.
