VIN – Validation of the input signal

Block SymbolLicensing group: STANDARD

Function Description
The VIN block can be used for verification of the input signal quality in the REXYGEN system. Further details about quality flags can be found in chapter 1.4 of this manual.

The block continuously separates the quality flags from the input u and feeds them to the iqf output. Based on these quality flags and the GU parameter (Good if Uncertain), the input signals are processed in the following manner:

For $GU = off$ the output QG is set to on if the quality is GOOD. It is set to $QG = off$ in case of BAD or UNCERTAIN quality.
For $GU = on$ the output QG is set to onif the quality is GOOD or UNCERTAIN. It is set to $QG = off$ only in case of BAD quality.

The output yg is equal to the u input if $QG = on$ . Otherwise it is set to $yg = sv$ (substitution variable).

Inputs

u	Input signal whose quality is assessed. The type of the signal is determined upon the connected signal.	Any
sv	Substitute value for an error case	Any

Outputs

yg	Validated output signal ( $yg = u$ for $QG = on$ or $yg = sv$ for $QG = off$ )	Any
QG	Indicator of input signal acceptability	Bool
iqf	Complete quality flag separated from the u input signal	Long (I32)

Parameter

Acceptability of UNCERTAIN quality

Bool

off ..: Uncertain quality unacceptable
on ...: Uncertain quality acceptable
