Many thanks to all who replied.
By using Dave's code below along with either Rick's suggestion to use BI01 =
C:B.CIN..BO not B0 (as described in the Integrated Control Software Concepts
document B0193AW Connections to Source Status section) or the BI01=C:B.CIN,
STEP01=RBD BI01 after Tim encouraged me to check and confirm that .BAD does not
change state when the FBM is out of service - it looks like we've got a
workable solution. Alternatively, Russ suggested using MCIN/MCOUT blocks or a
separate BAD status indicator. Time to do a mock-up and see what OPS prefers.

This will do what you are asking (although a GDEV is better)
BI01 = the .BAD parameter
BI02 = the .CIN of the OPEN state
BI03 = the .CIN of the CLOSED state
any travel timing issues are left as an exercise for the reader.
TEST_FCP:VLV_STAT
TYPE = CALCA
DESCRP = SET VLV STATES
STEP01 = IN BI01 ; BAD BLOCK
STEP02 = IN 100 ;
STEP03 = MUL ; MULTIPLY BY 100
STEP04 = IN BI02 ; OPEN BIT
STEP05 = IN 10 ; MULTIPLY BY 10
STEP06 = MUL ;
STEP07 = IN BI03 ; CLOSED BIT
STEP08 = IN 20 ;
STEP09 = MUL ; MULTIPLY BY 20
STEP10 = ADD 3 ;
STEP11 = OUT RO01; 0=BOTH CLOSED
STEP12 = ; 10 = OPEN
STEP13 = ; 20 = CLOSED
STEP14 = ; 30 = BOTH LIMITS MADE
STEP15 = ; >30 = BAD
END
Later,
David
