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.

if the input signal u is evaluated as Quality Good $QG = on$ , it is fed to the output yg. In case of signal quality problems, a substitute signal from the input sv (substitution variable) is used for the output.

This block propagates the signal quality. More information can be found in the 1.4 section.
