APPENDIX 1. APPLICATION, SETTING AND CHANGE OF BASIC PARAMETERS
A1.3 Setting the AI Function
Block
The AI function block outputs the flow rate signals.
(1)Setting the flow range
Access the XD_SCALE parameter.
Set the required unit in Unit Index of XD_SCALE. Set the
upper range limit in EU at 100% of XD_SCALE. Set the
lower range limit in EU at 0% of XD_SCALE.
Set the decimal point position in Decimal Point of
XD_SCALE.
FA0102.EPS
Example:
To measure 0 to 100m
3
/h,
Set m
3
/h (1349)* in Units Index of XD_SCALE,
Set 100 in EU at 100% of XD_SCALE, and
Set 0 in EU at 0% of XD_SCALE.
Set 0 in Decimal Point of XD_SCALE.
(2)Setting the output scale
Access the OUT_SCALE parameter.
Set the required unit of output in Units Index of
OUT_SCALE.
Set the output value corresponding to the upper range limit
in EU at 100% of OUT_SCALE.
Set the output value corresponding to the lower range limit
in EU at 0% of OUT_SCALE.
Set the decimal position in Decimal Point.
FA0103.EPS
Example:
To set the output to 0.00 to 100.00kg/h,
Set kg/h(1324)* to Units Index of OUT_SCALE,
Set 100 to EU at 100% of OUT_SCALE,
Set 0 in EU at 0% of OUT_SCALE, and
Set 2 to Decimal Point of OUT_SCALE.
* Each unit is expressed using a 4-digit numeric code.
Refer to Section 5.4 AI Function Block Parameters.
(3)Setting the output mode
Access the L_TYPE parameter.
Set the output mode. (In AXF series output mode is always
1:Direct so please confirm the setting.)
1: Direct
(Sensor output value)
2:Indirect
(Linear output value)
3:IndirectSQRT (Square root extraction output value)
FA0104.EPS
(4)Simulation
Perform simulation of the AI function block by setting
the desired value and status of the input to the block.
REMOTE LOOP TEST SWITCH is written to
SIM_ENABLE_MSG(index 1044) parameter of the resource
block.
Access the En/Disable element of the SIMULATE parameter
to enable simulation.
1: Disabled
2: Active
FA0105.EPS
Access the Simulate status element of SIMULATE and set
the desired status code.
Access the Simulate value element of SIMULATE and set the
desired input value.
If simulation is enabled, AI block uses SIMULATE
Status and SIMULATE Value as the input, and if
disabled, the AI block uses Transducer Status and
Transducer Value as input.
Refer to Section 6.3 "Simulation Function."
