SEL – Selector switch for analog signals

Block SymbolLicensing group: STANDARD

Function Description
The SEL block is obsolete, replace it by the SELQUAD, SELOCT or SELHEXD block. Note the difference in binary selector signals SW $n$ .

The SEL block selects one of the four input signals u1, u2, u3 and u4 and copies it to the output signal y. The selection is based on the iSW input or the binary inputs SW1 and SW2. These two modes are distinguished by the BINF binary flag. The signal is selected according to the following table:


iSW	SW1	SW2	y

0	off	off	u1
1	off	on	u2
2	on	off	u3
3	on	on	u4

This block does not propagates the signal quality. More information can be found in the 1.4 section.

Input

u1	First analog input of the block	Double (F64)
u2	Second analog input of the block	Double (F64)
u3	Third analog input of the block	Double (F64)
u4	Fourth analog input of the block	Double (F64)
iSW	Active signal selector	Long (I32)
SW1	Binary signal selector	Bool
SW2	Binary signal selector	Bool

Parameter

BINF

Enable the binary selectors

Bool

off ..: Disabled (analog selector)
on ...: Enabled (binary selectors)

Output

y	The selected input signal	Double (F64)
