Dear All,

Here i have four no of softbit as below

STYLE1:bool
STYLE2:bool
STYLE3:bool
STYLE4:bool

if i selected style-1 (status=true), remaining styles2,3,4 status are 0 suppose those any one styles status are 1.

if i selected style-2 (status=true), remaining styles1,3,4 status are 0 suppose those any one styles status are 1.

if i selected style-3 (status=true), remaining styles1,2,4 status are 0 suppose those any one styles status are 1.

if i selected style-4 (status=true), remaining styles1,2,3 status are 0 suppose those any one styles status are 1.

I Was tried but not working.logic as below

S1TEMP2:STYLE1 AND NOT S1TEMP1;
S1TEMP1:=STYLE1;

S2TEMP2:STYLE2 AND NOT S2TEMP1;
S2TEMP1:=STYLE2;

S3TEMP2:STYLE3 AND NOT S3TEMP1;
S3TEMP1:=STYLE3;

S4TEMP2:STYLE4 AND NOT S4TEMP1;
S4TEMP1:=STYLE4;

STYLE1:=NOT S2TEMP2 AND NOT S3TEMP2 AND NOT S4TEMP2;
STYLE2:=NOT S1TEMP2 AND NOT S3TEMP2 AND NOT S4TEMP2;
STYLE3:=NOT S1TEMP2 AND NOT S2TEMP2 AND NOT S4TEMP2;
STYLE4:=NOT S1TEMP2 AND NOT S2TEMP2 AND NOT S3TEMP2;

Kindly give us solution.

Example for 3rd bit

.....

CONST

 MASK_STYLE_3 := 2#00000100

....

Style := 1*BOOL_TO_INT(Style_1_bool) +  2*BOOL_TO_INT(Style_2_bool) + 4*BOOL_TO_INT(Style_3_bool) .....

.....

Style_3_selected := (Style =   MASK_STYLE_3); 

....
