A1.3 Setting the AI Function Block
The AI function block calculates the flow rate outputs.
Setting the flow range
„ „
Access the XD_SCALE parameter.
Set the required unit for the measurement range to Unit Index for XD_SCALE.
Set the upper range limit to EU at 100% of XD_SCALE.
Set the lower range limit to EU at 0% of XD_SCALE.
Set the decimal point position to Decimal Point of XD_SCALE.
Example: To measure 0 to 1003/h, set each item as follows:
Set 1349 to
Set 100 to
Set 0 to
Set 0 to
Setting the output scale
„ „
Access the OUT_SCALE parameter.
Set the required unit of output to Units Index of OUT_SCALE.
Set the output value corresponding to the upper range limit to EU at 100% of OUT_SCALE.
Set an output value corresponding to the lower range limit to EU at 0% for OUT_SCALE.
Set the decimal point to Decimal Point.
For example: To set the output from 0.00 to 100.00 kg/h, set each item as follows:
Set 1324 to
Set 100 to
Set 0 to
Set 2 to
*1 For a description code about the unit, refer to "List of Unit Code" in Section 6.9.
Setting the output mode
„ „
Access the L_TYPE parameter. Set the output mode.
(In this product, the output mode is always 1:Direct.)
1 : Direct (Sensor output value)
2 : Indirect (Linear output value)
3 : IndirectSQRT (Square root extraction output value)
Simulation
„ „
Perform the simulation of the AI function block by setting the desired value and status of the input
to the block.
(1) REMOTE LOOP TEST SWITCH is written to the SIM_ENABLE_MSG (index 2922)
parameter of the MTB.
(2) Access the En/Disable element of the SIMULATE parameter to enable simulation. Set the
simulation active or disable.
1 : Disable (invalid)
2 : Active (valid)
