Configuring the Flow AI block
Double click on the “Flow” AI block.
If the MODE_BLK.TARGET of the AI block is not set to ‘OOS’, set it to ‘OOS’.
Note: Some parameters can be written only if the MODE_BLK.
ACTUAL is set to ‘OOS’.
• Set the CHANNEL parameter to “Flow average”.
• Set the UNITS_INDEX parameter to the desired flow units i.e. “L/s”.
• Set the L_TYPE parameter to “Indirect” It can also be ‘Direct’ if XD_SCALE and
OUT_SCALE parameters have the same values.
Confirm that the BLOCK_ERR parameter indicating ‘Out of Service’. Once all of the
above have been confirmed, set the block Mode into AUTO, and confirm that the
bock is providing updated flow process data in the OUT parameter. If all conditions
are met then the MODE_BLK.ACTUAL parameter of AI block goes into ‘Auto’.
Configuring the Temperature AI Block
The configuration process is similar to the Flow AI block except for the parameter setting below.
• Set the CHANNEL parameter to “Temperature average”.
• Set the UNITS_INDEX parameter to the desired temperature units i.e. “°C”.
