Hi,
I have come up with something like the below; then connect BO01 to MANSW 
parameter of the controller. I will test for pulsing MANSW possibly using OSP, 
or ON delay or OFF delay so that controller goes to manual only once if that 
happens

STEP01

CLM M02 ; # LLL

STEP02

IN  RI01; LS6451

STEP03

LAC M01 ; 10%

STEP04

SUB     ;

STEP05

BIP 7   ;

STEP06

INC M02 ; LS6451 <10%

STEP07

IN  RI02; LS6452

STEP08

LAC M01 ; 10%

STEP09

SUB     ;

STEP10

BIP 12  ;

STEP11

INC M02 ; LS6452 <10%

STEP12

IN  RI03; LS6453

STEP13

LAC M01 ; 10%

STEP14

SUB     ;

STEP15

BIP 17  ;

STEP16

INC M02 ; LS6453 <10%

STEP17

LAC M02 ; # <10%

STEP18

IN  2   ;

STEP19

SUB     ;

STEP20

BIP 23  ;

STEP21

CLR BO01; NO LLL

STEP22

GTO 24  ;

STEP23

SET BO01; 2/3 LLL !

STEP24

EXIT    ;


Thanks
Regards,
Srini

Subject: 2OO3 logic Possible?

Hi,

I would like to try the 2OO3 voting logic in DCS to place a controller in 
manual if 2 of the 3 readings fail. I am trying to explore the CACA block or 
IND sequence block. Any comments, please pass it on, thank you for your time

Kind Regards,
Srini
