OUT_SCALE
Scale of the Process Variable.
The Function Block parameter OUT_SCALE contains the values of the lower limit and
upper limit effective range, the code number of the engineering unit of Process Variable
and the number of digits on the right hand side of the decimal point.

PV_FTIME
Filter time of the Process Variable.
The Function Block parameter PV_FTIME contains the time constant for the rise time of
the FB output up to a value of 63.21 % resulted from a jump on the input (PT1 filter). The
engineering unit of the parameter is second.

FSAFE_TYPE
Defines the reaction of device, if a fault is detected. The calculated ACTUAL MODE
remains in AUTO.
For mode FSafe Value, the block parameter FSAFE_VALUE is used as OUT and the
status is set to UNCERTAIN_Substitute Value,
In mode Last Stored, the last stored valid OUT value is used as OUT and the status is set
to UNCERTAIN_LastUsableValue. If there is no valid value available, the status is set to
UNCERTAINInital_Value and the OUT value is set to its initial value.
In the mode Out Status Bad, OUT has the wrong calculated value and status is set to
BAD_* (with * as calculated).
