9.3 Scaling the OUT parameter
In the Analog Input Block, the input value or input range can be scaled in accordance with
the automation requirements.
Example:
The measuring range 0 to 500 mbar should be rescaled to 0 to 100 %.
• Select XD_SCALE group.
– For EU_0, enter "0".
– For EU_100, enter "500".
– For UNITS_INDEX, enter "mbar".
• Select OUT_SCALE group.
– For EU_0, enter "0".
– For EU_100, enter "100%".
– For UNITS_INDEX, select "%" for example.
The unit selected here does not have any effect on the scaling.
•Result:
At a pressure of 350 mbar, the value 70 is output to a downstream block or to the PCS as
the OUT value.

CAUTION
!
Note Dependencies when setting parameters!
‣ If you have selected the "Direct" mode for the L_TYPE parameter, you cannot change the
values and units for XD_SCALE and OUT_SCALE.
‣ The L_TYPE, XD_SCALE and OUT_SCALE parameters can only be changed in the OOS
block mode.
‣ Make sure that the output scaling of the Pressure Transducer Block SCALE_OUT matches
the input scaling of the Analog Input Block XD_SCALE.
