### SEL – Selector switch for analog signals

Block SymbolLicensing group: STANDARD

Function Description
The SEL block is obsolete, replace it by the SELQUAD block.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

Inputs

 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, active when $\mathtt{\text{BINF}}=\mathtt{\text{off}}$ Long (I32) SW1 Binary signal selector, active when $\mathtt{\text{BINF}}=\mathtt{\text{on}}$ Bool SW2 Binary signal selector, active when $\mathtt{\text{BINF}}=\mathtt{\text{on}}$ Bool

Output

 y The selected signal Double (F64)

Parameter

 BINF Enable the binary selectors Bool off .. Disabled (analog selector) on ... Enabled (binary selectors)
