156 Operating Instructions, 01/2014, A5E32221411-AB
Upper Value (2.6.4.2.)
Defines the operational upper range value of the input value (Process Value Scale) in PV
(volume/level) Units. Process Value Scale normalizes the input value to a customer-defined
range.
Values
Range: -999999 to 999999
Default: 100 %
Provides Output values
(Out) to AIFB 1 or AIFB 2
Unit (2.6.4.3.)
Engineering unit to be displayed with the output value.
Values
m, cm, mm, ft, in, cu m, L, HL, cu in, cu ft, cu yd, gal, imp gal,
bushels, Bbl, Bbl liquid, percent, PA, Follow out unit
*
%
Decimal Point (2.6.4.4.)
Read only. The number of digits to display after the decimal point (set to 0 decimal places).
Output Scaling (2.6.5.)
Scales the Process Variable. The function block parameter OUT SCALE contains the values of
the lower limit and upper limit effective range in AIFB 1 units.
Lower Value (2.6.5.1.)
Defines the operational lower range value of the output value in AIFB 1 units.
Values
Range: -999999 to 999999
Default: 0%
