Issue
The FlexAnalog object in the I/A Series R2 programLib jar does not pass the NaN (not a number) to the link when the value at the FlexAnalog input is changed from a valid value to NaN.
Product Line
TAC IA Series
Environment
I/A Series R2
Cause
The object was based off the standard Analog Input object where the object holds the last valid value when NaN is applied to the input.
Resolution
There is a jar available that has an updated FlexAnalog object that will pass the NaN to the link when the value at the FlexAnalog input is changed from a valid value to NaN (not a number). Contact Product Support Services to obtain this jar.
