APPENDIX 2. APPLICATION, SETTING AND CHANGE OF BASIC PARAMETERS
Restrictions imposed when the device is
equipped with a built-in indicator.
When the output mode (L_TYPE) is set as Indirect
or IndirectSQRT, the range determined by the
output scale corresponds to the scale and unit of the
indicator. Set the lower and higher value of the
range (numeric string excluding decimal point if the
decimal point is included) in a range of –19999 to
19999. Down to the third decimal position can be
set. (When the output mode (L_TYPE) is set as
Direct, unit determined at XD_SCALE is displayed.)

(3)Setting the output mode
FA0204.EPS
Access the L_TYPE parameter.
Set the output mode.
1: Direct
2: Indirect
3: IndirectSQRT (Sensor output value)
(Linear output value)
(Square root extraction
output value)
(4)Setting the output signal Low Cut
Set the low cut value.
FA0205.EPS
Access the LOW_CUT parameter.
Set the value subject to LOW_CUT.
Access the IO_OPTS parameter.
Turn Low cutoff ON.
If Low cutoff is turned OFF, Low cut function is
released.
(5)Setting the damping time constant
FA0206.EPS
Access the PV_FTIME parameter.
Set the damping time (in seconds).
(6)Simulation
By optionally setting the input value to the calibra-
tion range and status, perform simulation of the AI
function block.
FA0207.EPS
Access the Simulate Value parameter.
Set an optional input value.
Access the Simulate Status parameter.
Set the status code.
Access the Simulate En/Disable parameter.
Set whether Simulation is enabled or disabled.
2: Enabled
1: Disabled
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.
