draw for me the sequential function chart of the following program

VAR

Timer$1$ : TON ; $//$ Timer for $01$

$01,02$ : BOOL; $//$ outputs This program sets $01$ to turn on for $10$ seconds when S$1$ turns on$.$ After $10$ seconds, $01$ turns off and $02$ turns on until S$2$ turns on$.$

END$\_$VAR

IF S$1$ THEN

$//$ when S$1$ turns ON$,$ start Timer$1$

Timer$1($IN :$=$ TRUE, PT ;$=$ T#$10$s$)$;

$01$ :$=$ Timer$1.$Q; $//$ output $01$ follows Timer$1$

ELSE

Timer$1($IN :$=$ FALSE$)$ ; $//$ Reset Timer$1$ if S$1$ is off

$01$ :$=$ FALSE; $//$ Reset $01$ if $S1$ is OFF

END$\_$IF

IF S$2$ THEN

$02$ :$=$ TRUE; $//$ when S$2$ turns ON$,$ turn on $02$

ELSE

$02$ :$=$ FALSE; $//$ Reset $02$ if $S2$ is OFF

END$\_$IF
