12.2.4 Configuring the Analog Input Blocks
The device has 2 permanently instanced Analog Input Blocks that can be assigned as
required to the various process variables. If required, up to 5 Analog Input Blocks can be
instanced through the FOUNDATION Fieldbus configuration tool.
Default settings
Analog Input Block
CHANNEL
AI 1
32949: Level linearized
AI 2
32856: Distance
1. If necessary, change the block name.
2. Set the block mode to
OOS
by means of the
Block Mode/MODE_BLK
parameter,
TARGET
element.
3. Use the
Channel/CHANNEL
parameter to select the process variable which should
be used as the input value for the Analog Input Block.
4. Use the
Transducer Scale/XD_SCALE
parameter to select the desired unit and the
block input range for the process variable → 82. Make sure that the unit
selected suits the process variable selected. If the process variable does not suit the
unit, the
Block Error/BLOCK_ERR
parameter reports
Block Configuration Error
and the block mode cannot be set to
Auto
.
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
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.
12.2.5 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.
12.3 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.
