You can also forward the quality attributes unchanged. To do this, you must mark the
Keep flag
check box.
Functional Logoff by Operator Blocked
You have set the
Operation mode
to
Device logoff
=
true
in the transmitting device. As a result, every
indication issued from the functions and subject to
Device logoff
is transmitted with the quality informa-
tion
operator blocked
and Validity =
good
. The receiver recognizes this for this indication and reacts
according to the settings (
). A different quality processing can take place only once you have set the
Operation mode
to
Device logoff
=
true
in the transmitting device.
Communication Outage
There is a communication disturbance (time allowed to live) between the transmitter and the receiver indi-
cated by the transmitter. The indication is set in accordance with the settings (
).
Invalidity
The transmitting device sends this indication with the quality information Validity =
invalid
. The receiver
recognizes this for this indication and reacts according to the settings (
Questionable
The transmitting device sends this indication with the quality information Validity =
questionable
. The
receiver recognizes this for this indication and reacts according to the settings (
).
Test Mismatch
The transmitting device or the function in the transmitting device that issues this indication is in test mode. As
a result, the indication is transmitted with the quality information
test
. The receiving function block recog-
nizes this for this indication and reacts, depending on its own test-mode state (specified in IEC 61850-7-4
Annex A), according to the settings (
).

NOTE
Follow the sequence of tests. First, the Functional logoff by operator blocked is tested. Then comes
Communication outage and so on. If a case is recognized as
active
, the test chain is canceled with the
configured setting for the active case.
In the case of Invalidity, the tests are first performed for Functional logoff by operator blocked (not appli-
cable) and then for Communication outage (not applicable) and canceled with the configured action for
Invalidity.
If an indication is routed into the log, manual updating of a value is also logged based on the conditions listed
above and on the reason for the manual update. Manually updating a value based on the conditions listed
above causes a change in the
Health Warning
function block, inherited up to
Device health
(specified
in IEC 61850-7-4).
Keep Value
The quality attributes and values indicated by the transmitter are accepted without change. Quality processing
must be performed by the user via a logic diagram. The outputs of the logic diagram following the user-
specific quality processing can be connected to the function-block inputs as before.
