Prevention
More than the maximum number of
Sensors are connected at Distributed
Sensor Unit.
Reduce the number of Sensors at rel-
evant Distributed Sensor Unit to less
than the maximum number of Sen-
sors at Distributed Sensor Unit.
Do not connect more than the maxi-
mum number of Sensors at Distrib-
uted Sensor Unit.

Prevention
There are too many Dummy Units set,
so some Sensors are not assigned
logical unit numbers.
Reduce the number of Dummy Units
that is set in the dummy function set-
tings so that logical unit numbers can
be assigned to all connected Sen-
sors, and then change the Sensors
from the Init state to Pre-operational
state or restart the Sensors.
Set Dummy Units so that logical unit
numbers can be assigned to all Sen-
sor Amplifiers that are connected.
