Reading comparator values (P.V. values) from sensor amplifiers

This example shows how to read the comparator values (P.V.values) from the sensor
amplifiers ID01, ID02, and ID03.

(1) When the comparator value of a sensor amplifier is updated, the value of the input

address is also updated via data I/O communication.
If the judgment value is correct, the parameter range is
- from - 999.99 to +999.99 (percent mode).
- from - 99.999 to +99.999 (size mode).
If the comparator value is over range, under range, or invalid, the previous value is
retained without updating the comparator value. To confirm whether the current
value is correct, use the comparator value property.

(2) The comparator value invalid, comparator value over range, or comparator value

under range is entered.
If the comparator value of a sensor amplifier is "invalid", "over", or "under", the bit
corresponding to the ID number of that sensor amplifier flips to 1.
