Flow-X─ Function Reference
Flow-X General functions - fxKeypadFallback
fxKeypadFallback
This function provides a generic interface to any input signal, such as a pressure, temperature, density
or flow input. It provides the option to override the 'live' value with a keypad value and to fallback to a
specific value when the input value is faulty.
When the input signal fails, the in-use value may fall back to the last good value, the keypad value or
additionally a separate fallback value. The fallback value allows the user to define a fixed value (e.g. 0)
that is independent from the current keypad value.
