7. Specify the alarm priorities by means of the High High Priority/HI_HI_PRI, High
Priority/ HI_PRI, Low Low Priority/LO_LO_PRI and Low Priority/LO_PRI parameters.
Reporting to the field host system only takes place with alarms with a priority greater
than 2.
8. Set the block mode to Auto using the Block Mode/MODE_BLK parameter, TARGET
element. For this purpose, the Resource Block must also be set to the Auto block mode.
11.1.5 Additional configuration
1. Link the function blocks and output blocks.
2. After specifying the active LAS, download all the data and parameters to the field
device.
11.2 Scaling of the measured value in an AI Block
If the type of linearisation L_TYPE = indirect has been selected in an AI block, the measured
value can be scaled within the block. The input range is defined by the XD_SCALE parameter
Through its EU_0 and EU_100 elements. This range is mapped linearly to the output ranged
defined by the OUT_SCALE parameter through its EU_0 and EU_100 elements.

 11 Scaling of the measured value in an AI Block
• 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.
