1.5 Scaling Function

Ex.
When 32000 is set to the scaling upper limit value and -32000 is set to the scaling lower limit value for the module with the
input range of 4 to 20mA (extended mode)
*1 Because the value falls below the range of -32768 to 32767, the value is fixed to -32768 (the lower limit value).
*2 Because the value exceeds the range of -32768 to 32767, the value is fixed to 32767 (the upper limit value).
When the scaling function is used with the digital clipping function, the scale conversion is performed on the
digital operation values after digital clipping.
