13.6.5 Function retaining valid conversion value
When the valid signal is out of the range, the last converted valid input value is retained.
The function retaining valid conversion value is able to designate for each channel by user program
and I/O parameter setting.
1) Used input range
In the channels that allow the function retaining valid conversion value, the actual ranges
provided within each digital conversion value are shown.
For example, in case of operating output data type of unsigned value, original digital output value
is shown from -192 to 16,191.
However, if this function is allowed, it will be shown from 0 to 16,000.
