Variable Name / Brief Description
/ Rel. Idx
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 Unused, 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.
0x0309: TB3.VOLUME_REVERSE
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
FSAFE_VALUE
34 / 18
Default value for the OUT parameter, if a sensor or sensor electronic fault is detected. The
unit of this parameter is the same as that for OUT.
ALARM_HYS
35 / 19 Hysteresis value applied to block parameters HI_HI_LIM, HI_LIM, LO_LIM and
LO_LO_LIM. The hysteresis is expressed as value below high limit and above low limit in
the engineering unit of xx_LIM.
UNUSED
36 / 20
Unused parameter.
HI_HI_LIM
37 / 21 Upper limit value for alarms with the same engineering unit as that of the OUT parameter.
If the measured variable is equal to or higher than the upper limit value, the State Bits in
the Status Byte of OUT and in the FB parameter ALARM_SUM change to 1.
UNUSED
38 / 22
Unused parameter.
HI_LIM
39 / 23 Upper limit value for alarms with the same engineering unit as that of the OUT parameter.
If the measured variable is equal to or higher than the upper limit value, the State Bits in
the Status Byte of OUT and in the FB parameter ALARM_SUM are set to 1.
