Logical
Selectivity -
Repetition
The
Ekip Link advanced selectivity
page includes the parameter
Repeat Configuration mask
that allows selecting the protections whose logical selectivity bit
– if present at the input – must
be propagated regardless of the protection state of the current unit.
NOTE: the parameter acts exclusively on the selectivity bits, it does not affect the
hardware outputs
Logical
Selectivity -
Diagnostics
With both hardware and logical selectivity,
diagnostics
show possible wiring errors of the
hardware selectivity signals, verifying their continuity.
In the
Ekip Link Diagnostics Configuration
page one can: enable diagnostics, configure the time
interval between one check and the next, select the inputs to check for each active actor
(S/D_Forward, G/D_Backward).
Then:
A check of the hardware inputs is performed at regular intervals
If the input of an actor is configured for diagnostics using Ekip Touch (e.g. input S of actor
3) and the same input is not active at the time of the test, the actor stimulates the output
(e.g. actor 3 activates output S) for a short time: Ekip Touch considers the test outcome to
be positive if it correctly receives the message on its input, otherwise it signals an error
If the hw input is active the diagnostic is not performed: if the input configured for diagnostics
is active at the time of the test, the diagnostic is not performed and the parameter
Detection
status
in the
Ekip Link Status
page shows: Unknown
Logical
Selectivity -
errors and
inconsistency
Regardless of the diagnostics, if a hardware input is active and none of the logical selectivity bits
of the associated actors are active, a line inconsistency is signaled on the
Ekip Link Status
page
for this input.
NOTE: to check line inconsistency all the actors associated with the unit are checked,
even those for which the function has not been enabled (the Selectivity Actor parameter
has not been set to the value:
True
)
A line inconsistency (independent of diagnostics) is indicative of a possible configuration error
(for example: a hardware input of the release and connected to the hardware output of a device
not associated via Link Bus, or of an actor for which the function has not been enabled).
To avoid a line inconsistency from being signaled, the devices whose hardware outputs
are connected to the Ekip Touch hardware inputs must also be connected to the Link
Bus and associated with Ekip Touch, while it is not necessary for the function to be
enabled (the Selectivity Actor parameter does not have to be set to the value:
True
)
