Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Parameter description (FF configuration program)
Endress+Hauser 97
Linearization Type/
L_TYPE
Selection
Index: 16
Data type: unsigned8
Access: OOS
Select the linearization mode for the input value.
Options:
• Direct: In this setting, the input value bypasses the linearization function and is looped
unchanged with the same unit through the Analog Input function block. With this option
the scaling and unit of the Transducer Scale/XD_SCALE and Output Scale/OUT_SCALE
parameters must be identical. If this is not the case, the block goes to the OOS mode and
the "Block config error" message is displayed in the Block Error/BLOCK_ERROR
parameter.
• Indirect: The input value is rescaled linearly via the Transducer Scale/XD_SCALE input
scaling to the desired Output Scale/OUT_SCALE output range.
• Indirect square root: The input value is rescaled via the Transducer Scale/XD_SCALE
parameter and recalculated using a root function. It is then rescaled again to the desired
output range via the Output Scale/OUT_SCALE parameter.
Factory setting:
Direct
Low Cutoff/LOW_CUT
Entry
Index: 17
Data type: float
Access: auto, man, OOS
Enter the limit value for the low flow cut off. If the converted measured value is below this
limit value, the Process Value/PV parameter displays "0".
!
Note!
This parameter is only active if the "Low cutoff" option was activated via the I/O Options/
IO_OPTS parameter.
Input range:
Range and unit of Output Scale/OUT_SCALE (→ see Page 96)
Factory setting:
0
Prozesswert-Filterzeit/
PV_FTIME
Entry
Index: 18
Data type: float
Access: auto, man, OOS
Enter the filter time constant for the 1st order digital filter. This time is required in order for
63% of a change in the controlled variable IN to have an effect on the value of Process Value/
PV.
P01-xxxxxxxx-05-xx-xx-xx-021
Factory setting:
0 s
Field Value/
FIELD_VALUE
Display
Index: 19
Data type:
Access: read only
The Field Value/FIELD_VALUE parameter is a structured parameter consisting of two
elements.
VALUE
• Displays the process variables after input scaling of the Analog Input Block. The value
relates to a percentage of the input range Transducer Scale/XD_SCALE and is replaced by
the simulation value when simulation is active.
STATUS
• Displays the current status.
