When the scaling lower limit is smaller than the scaling upper limit, the lower limit
corresponds to output signal level 0%, the upper limit corresponds to output sig-
nal level 100%, and positive scaling is performed.
When the scaling lower limit is greater than the scaling upper limit, the lower limit
corresponds to output signal level 100%, the upper limit corresponds to output
signal level 0%, and reverse scaling is performed.

Conversion data
Conversion data set in engineering units is converted into a rate of 0% to 100%
(0 to 4095) according to the scaling upper and lower limits, subject to conver-
sion, and then generated as output signals.
To enable scaling, turn ON the Scaling Enable Bit for each output point. These
bits are read/write.
To check whether the scaling function is active, monitor the status of the Scaling
Enabled Flag for each output point. These flags are read-only.
