How about using a SIGSEL set to median select then using REALM blocks to
compare the individual inputs to the median. Additional logic can be using to
set the median to BAD, bypass an input, etc.

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

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
