Value Float R/W 0 Input and indication of the value corre-
sponding to 0 % of scale
28 OUT_SCALE - DS-36 R/W - Input and indication of process
variable's scale

Value Float R/W Det. by ordered
scale Corresponding OUT scale value to
100 %
EU_at_0% OUT Scale Lower
Value Float R/W 0 Corresponding OUT scale value to 0 %
Units_Index Unit Unsigned16 R/W Det. by ordered
scale Indication and setting of the OUT scale
unit
Decimal_Point Decimal Point Integer8 R/W 2 Memo of the number of valid digits
below decimal point
29 LIN_TYPE Characterization
Type
Unsigned8 R/W 0: No Linearisation Input and indication of linearization type
30 CHANNEL Channel Unsigned16 R/W Det. by ordered
scale Reference to the active Transducer
Block which provides the measurement
value
32 PV_FTIME Filter Time Constant Float R/W 0.0 Time constant of a single exponential
filter for the PV, in seconds
33 FSAFE_TYPE Fail Safe Mode Unsigned8 R/W 1 In case of BAD status the OUT is adju-
sted based on the following settings:
0: Value: FSAFE_VALUE, Status:
UNCERTAIN - Substitute Value
1: Value: last stored valid value, Status:
UNCERTAIN-last usable value
2: Value: actual, Status: no adjustment
34 FSAFE_VALUE Fail Safe Default
Value Float R/W 0 Default value for the OUT parameter in
case of BAD status.
35 ALARM_HYS Limit Hysteresis Float R/W 0.5 Absolute value of OUT value must re-
turn within the alarm limits before alarm
condition clears (in OUT scale unit).

OUT scale unit)
39 HI_LIM Upper Limit
Warning Float R/W 3.4038:
INF

(in OUT scale unit)
41 LO_LIM Lower Limit
Warning Float R/W -3.4038:
-INF
Setting of the lower limit warning value
(in OUT scale unit)
43 LO_LO_LIM Lower Limit Alarm Float R/W -3.4038:
-INF
