Rel. Idx
UNUSED
25 / 9
Unused parameter.
OUT
The Function Block parameter OUT contains the current measurement value in a
26 / 10
vendor-specific or configuration-adjusted engineering unit and the belonging state in
AUTO MODE. The Function Block parameter OUT contains the value and status set by
an operator in MAN MODE.
PV_SCALE
Conversion of the Process Variable into percent using the high and low scale values. The
engineering unit of PV_SCALE high and low scale values are related directly to the
27 / 11
PV_UNIT of the configured Transducer Block (configured via Channel parameter). The
PV_SCALE high and low scale values follow the changes of the PV_UNIT of the related
Transducer Block automatically – a change of the Transducer Block PV_Unit causes no
bump at OUT from AI.
OUT_SCALE
Scale of the Process Variable.
28 / 12
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.
LIN_TYPE
29 / 13 Linearization type (not used, fixed to NO_LINEARISATION).
0: No Linearization
CHANNEL
Reference to the active Transducer Block that provides the measurement value to the
30 / 14
Function Block.
0x0111: TB1.VOLUME_FLOW
UNUSED
31 / 15
Unused parameter.
PV_FTIME
Filter time of the Process Variable.
32 / 16
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
33 / 17
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).
0: Fsafe Value
1: Last Stored
2: Out Status Bad
