Output levels
parameter block - determine the range of output value, this block has
the following parameters:
•
Lower level
and
Upper level
- these parameters limit range of the output signal,
below this range input signal will have
Lower level
value and above this range
the signal will have
Upper level
value, relationship between Lower and Upper
levels is linear and it is limited by defined range, see
Fig. 7.91
,
•
Alarm level
– this parameter defines output value, when alarm state appears,
but with maintaining hardware output limitation (
3÷22mA
). Alarm state is when
source logical channel returns
-Err-
or the state of exceeding range: the low
-Lo-
state and high
-Hi-
state.
Lower level
and
Upper level
parameter describe the transfer equation (linear) - see
Fig. 7.90
.
Lower level
of the output defines the current which can be generated when the
value of the input signal is equal to the
Lower level
.
Upper level
of the output defines the
current which can be generated when the value of the input signal is equal to the
Upper level
.
