Pierrick,

You could do a simple numeric calculation in a calc record and send the
output to an mbbi record to give you the string interpretations:

record(calcout,"MICE-ENV-AC-LEAK-04:calStatus") {
        field(DESC,"Water leak status determination")
        field(SCAN,"10 second")
        field(INPA,"MICE-ENV-SECPRB-01:WaterLeakStatus4")
        field(INPB,"MICE-ENV-SECPRB-01:WaterLeakValue4")
        field(CALC,"(A=2||A=4)&&B=0?0:(A=2||A=4)&&B=1?1:2")
        field(OUT,"MICE-ENV-AC-LEAK-04:status PP")
}
record(mbbi,"MICE-ENV-AC-LEAK-04:status") {
        field(ZRST,"Dry")
        field(ONST,"Leak detected")
        field(TWST,"Error")
}

Hi Kurt,
I'm still having trouble with my db.  This is actually what I have.  The
problem
appears to be in the definition of INAA, INBB, INCC.  When I do a caget
or
camonitor of  MICE-ENV-AC-LEAK-04:calStatus.AA, I find that I have no
value
stored there.  I do see the fields INAA, etc, defined in the dbd file.

The calculation works correctly, as I get the expected 1,0,-1 if I use
the
uncommented CALC line.

record(scalcout,"MICE-ENV-AC-LEAK-04:calStatus") {
        field(DESC,"Water leak status determination")
        field(SCAN,"10 second")
        field(INPA,"MICE-ENV-SECPRB-01:WaterLeakStatus4")
        field(INPB,"MICE-ENV-SECPRB-01:WaterLeakValue4")
        field(INAA,"Dry")
        field(INBB,"Leak detected")
        field(INCC,"Error")
#       field(CALC,"(A=2||A=4)&&B=0?AA:(A=2||A=4)&&B=BB?1:CC")
        field(CALC,"(A=2||A=4)&&B=0?0:(A=2||A=4)&&B=1?1:-1")
        field(SVAL,"MICE-ENV-AC-LEAK-04:Status")
        field(FLNK,"MICE-ENV-AC-LEAK-04:Status.PROC")
}
#record(stringout,"MICE-ENV-AC-LEAK-04:Status") {
record(ao,"MICE-ENV-AC-LEAK-04:Status") {
        field(DESC,"AC unit water drip status")
        field(SCAN,"Passive")
        field(FLNK,"MICE-ENV-AC-LEAK-01:foStatus.PROC")
}

Any ideas?  Thanks,
Pierrick
