Normalizer_With_Limiter: Scaling the Minimum and Maximum Input

Normalizer_With_Limiter Function Block

Pin Diagram

This figure shows the pin diagram of the Normalizer_With_Limiter function block:

Functional Description

The Normalizer_With_Limiter function block scales the minimum and maximum input value to the range of minimum and maximum output value. The input value can be limited to minimum and maximum output values.

The output value can be limited to minimum and maximum output values using i_xIputMinLim and i_xIputMaxLim.

When the input exceeds the maximum/minimum input limit value q_xIputLimExcd will be TRUE.

TRUE	FALSE	10	2048	FALSE
TRUE	FALSE	7.5	1024	FALSE
TRUE	TRUE	5	0	FALSE
FALSE	TRUE	2.5	-1024	FALSE
FALSE	TRUE	0	-2048	FALSE
FALSE	TRUE	-2.5	-2048	TRUE
FALSE	FALSE	-2.5	-3072	TRUE
