IN is zero
OUT is set to zero
The DECO parameter OUT data type selection of a Byte, Word, or DWord restricts the
useful range of parameter IN. If the value of parameter IN exceeds the useful range, then a
modulo operation is performed to extract the least significant bits shown below.
DECO parameter IN range:
●
3 bits (values 0-7) IN are used to set 1 bit position in a Byte OUT
●
4-bits (values 0-15) IN are used to set 1 bit position in a Word OUT
●
5 bits (values 0-31) IN are used to set 1 bit position in a DWord OUT

Table 7- 133 SEL (select) instruction
LAD / FBD
SCL
Description
out := SEL(
g:=_bool_in,
in0:-_variant_in,
in1:=_variant_in);
SEL assigns one of two input values to parameter OUT, depending
on the parameter G value.
