The block makes a binary selection – analogous to the SEL block. In contrast to that block, SEL_LWORD allows the connection with LWORD only (for IN0 and IN1).

Inputs, return value

	Identifier	→Data type	Description
Inputs:	`G`	`BOOL`	selector
	`IN1`	`LWORD`	1st value
	`IN2`	`LWORD`	2nd value
Return value:	–	`LWORD`

Input EN and output ENO are available when →calling the block. See "Execution control: EN, ENO" for information on input EN and output ENO.

Example for usage within ST-editor

PROGRAM Test
    VAR
        result1 : LWORD;
        result2 : LWORD;
    END_VAR
    result1 := SEL_LWORD(G := FALSE, IN0 := LWORD#0000_0000_0000_0001, IN1 := LWORD#0000_0000_0000_0002);   (* The variable 'result1' evaluates to 'LWORD#0000_0000_0000_0001'. *)
    result2 := SEL_LWORD(G := TRUE, IN0 := LWORD#0000_0000_0000_0001, IN1 := LWORD#0000_0000_0000_0002);    (* The variable 'result2' evaluates to 'LWORD#0000_0000_0000_0002'. *)
END_PROGRAM
