Aifb2; Measured Values; Filtering - Siemens SITRANS LR560 Operating Instructions Manual

2.5.9.2.
Note: Fail-safe Mode (2.5.9.) must be set to Substitute Value before Value
(2.5.9.2.) can be defined.
User-defined default for the Output Value, if sensor or sensor electronic
fault is detected. Units are defined in Unit (2.5.8.2.).
Values

2.6. AIFB2

See AIFB1 (2.5.): the parameters for AIFB2 are identical.

2.7. Measured Values

Read only. Allows you to view measured values for diagnostic purposes
In SIMATIC PDM, open the menu View – Process Variables.
2.7.1. Main Output
The value for Level/Volume. (PV– Primary Value).
2.7.2. Output, no linearization
The value for Level (SV1 – Secondary Value 1).
2.7.3. Output, no level offset
The value for Distance (SV2 – Secondary Value 2).

2.8. Filtering

2.8.1. Narrow Echo Filter
Filters out echoes of a specific width.
Values
To remove a false echo from the Echo Profile, take its width in mm and multiply
it by 0.013. Enter the result.
For example, to filter out a spike with 500 mm width, enter 6 or 7 (the closest
integer product of 500 x 0.013).
When a value is keyed in, the nearest acceptable value is entered.
2.8.2. Reform Echo
Smooths jagged peaks in the echo profile. Reforms fragmented echoes into one
echo.
