n
Fail Safe Mode
Fail Safe Mode defines the Output Value and Status (Quality) when status of input signal to AI
function block or Totalizer function block is BAD.
This function is valid only when Actual Mode of AI function block is in “AUTO”
n
Output Value (OUT)
The function block parameter OUT contains the current measurement value in a vendor specific
or configuration adjusted engineering unit and the belonging status in Auto Mode. Also contains
the value and status set by an operator in Man Mode.
n
Simulation (SIMULATE)
Simulation parameter is to simulation mainly for checking arbitrarily set the value and input status
from SENSROR Transducer block.
n
PV Scale (PV_SCALE)
Conversion of the process variable into percent using the high and low scale values.
n
Linearization type (LIN_TYPE)
Linearization type of output signal can be select from Linear or Square root. Linearization type
of AI function block can apply to have different output mode for display and output signal. (For
example, Display mode: Square root, Output mode: Linear)
n
Out Scale (OUT_SCALE)
Scale of the process variable. This parameter contains the values of the lower limit and upper
limit effective range, the code number of the engineering unit of process variable and the useful
number of digits on the right hand side of the decimal point.
n
Filter Time Const (PV_FTIME)
Damping time of the process variable.
