Flt/Warn #
Connector for current alarm number
and current fault number.
Upper byte: fault number
Lower byte: alarm number.
The value 0 means that no alarm or
fault is present. Attention: The alarm
number and the fault number are not
updated at the same time as the fault
or warning bit in the status word; they
are staggered a few sampling periods.

Compact PLUS only
Short-Time I2t
This connector provides information
on the status of the short-time I2t
monitoring. This monitoring is always
active whenever the current quantity
exceeds 1.6 times the converter rated
current (I_Conv_Rated). The
integrator does not return until the
current quantity falls below 0.9
I_Conv_Rated. If the connector
achieves the value 100%, the current
limit (r129) is reduced to 0.9
I_Conv_Rated.

SoL.Rec.ActErr
Connector for output of the current
error value of the LC receiver block:
The connector is reset to 0 with a 0->1
edge of binector B0241, and as long
as binector B0241=1, if a sign of life is
omitted the connector is incremented
by 10, and if a valid sign of life is
received the connector is
decremented by 1.

SoL.Rec.
Connector for output of the number of
times that the sign of life has been
omitted since power up. This omission
counter is reset only when the power
supply for the electronics (24V) is
switched on.
