Fault suppression time in seconds.
Transmission of an analog value located in the overshoot or undershoot range
(7FFF
H
or 8000
H
) is suppressed for the time period specified here. The value
H
or 8000
H
is only sent after this time has elapsed, if it is still pending. If
the value returns to below 7FFF
H
or above 8000
H
again before this time
elapses, it is immediately sent again as normal. The suppression time is star
t-
ed again for the full duration the next time 7FFF
H
or 8000
H
is acquired.
This is typically used for temporary suppression of current values that may
occur when powerful pumps
and motors are started. The analog input may
exceed the maximum range several times under some circumstances. Su
p-
pression prevents these values from being signaled as faults in the control
center system.
The suppression is adjusted to analog values that a
re acquired by the S7 ana-
log input modules as raw values. These modules return the specified values
for the overflow or underflow range for all input ranges (also for life
-zero in-
puts). With provided ready values, fault suppression is only possible if thes
e
also adopt the values 7FFF
H
or 8000
H
when there is overshoot or undershoot.
If this is not the case, the parameter does not need to have a value entered.
The parameter can also be used in combination with the mean value calcul
a-
tion for temporary suppress
ion of the values 7FFF
H
or 8000
H
(see parameter
If no parameter is specified, the default of 0 seconds applies. An acquired
value of 7FFF
H
or 8000
H
is then sent immediately when it is first detected or,
with mean value calculation, as
an invalid mean value for the current mean
value calculation period.
