VAR 
    INPUT:REAL;
    SELECTOR:INT;   
    O1,O2: REAL;
    FB: LIB.CORE.V1_0.B10_ANALOGUE_DEMULTIPLEXER;

Description

The block implements a demultiplexer for REAL variables.

Inputs

Input	Type	Description	Default value
IN	REAL	Input value	0
SEL	INT	Output selector	0
DEFAULT	REAL	Default value of all outputs	0

Outputs

Output	Type	Description
OUT	REAL	Output signal.

Function

The block implements a demultiplexer for REAL variables. Setting of SEL=1 means that IN is copied to the OUT[1] output, SEL=2 means that IN is copied to OUT[2], etc. All other outputs are set to the DEFAULT value. If SEL does not match any of the available outputs (SEL<1 or sel>16), all outputs are in the DEFAULT value.
