L_TYPE
Selection

Data type: Unsigned8
Access: OOS
Select linearisation mode for the input value.
Options::
• Direct: in this setting, the input value bypasses the linearisation function and is looped
unchanged with the same unit through the Analog Input Block. If this option is selected,
the scaling and unit for the XD_SCALE and OUT_SCALE parameters must be identical. If
this is not the case, the block changes to the OOS mode and the "Block Config Error" error
is displayed in the BLOCK_ERROR parameter.
• Indirect: the input value is rescaled linearly via the input scaling XD_SCALE to the desired
output range OUT_SCALE.
• Indirect square root: the input value is rescaled by means of the XD_SCALE parameter and
recalculated using a root function. Further rescaling to the desired output range then takes
place via the OUT_SCALE parameter.
Factory setting:
Direct
