5. Use the Linearization Type/L_TYPE parameter to select the type of linearization for
the input variable (factory setting: Direct). Make sure that the settings for the
Transducer Scale/XD_SCALE and Output Scale/ OUT_SCALE parameters are the
same for the Direct linearization type. If the values and units do not match, the Block
Error/BLOCK_ERR parameter reports Block Configuration Error and the block mode
cannot be set to Auto.
6. Enter the alarm and critical alarm messages by means of the High High Limit/
HI_HI_LIM, High Limit/HI_LIM, Low Low Limit/LO_LO_LIM and Low Limit/LO_LIM
parameters. The limit values entered must be within the value range specified for the
Output Scale/ OUT_SCALE parameter → 60.
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 and the Setup Transducer 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.
