Hi Lewis,

about my previous problem I was wondering if I could do the conversion in one step with something similar as below (This does not work)

record(ao, "$(S):$(D)_$(C):CavVSet")
{
   field(DTYP, "asynFloat64")
   field(OUT,  "@asyn($(PORT),$(ADDR),$(TIMEOUT))cavvolt")
   field(VAL, "0")
   field(PREC, "2")
}
record(calcout, "$(S):$(D)_$(C):CavMilliVSet")
{
field(OUT, "$(S):$(D)_$(C):CavVSet PP")
field(OCAL, "1000 * VAL") 
field(PINI, "YES")
field(PREC, "1")
}

Actually I am doing as below, but I need a temporary record to perform this conversion, and It would be simpler to use one record less.

record(ao, "$(S):$(D)_$(C):CavMilliVSet")
{
field(DESC, "CavMilliVSet Temporary Set Record")
field(PINI, "YES")
field(EGU,  "mV")
field(PREC, "1")
}
record(calcout, "$(S):$(D)_$(C):CavMilliVCalc")
{
field(OUT, "$(S):$(D)_$(C):CavVSet PP")
field(CALC, "1000 * A")
field(INPA, "$(S):$(D)_$(C):CavMilliVSet.VAL CP MS")
field(PINI, "YES")
}


Regards

Hi,

I was afraid that asynFloat64 did not support the LINR field since there is nothing in asyn documentation.
I didn't want to create a CavMilliVolSet field but I think I don't have any other solution if I don't want to modify my driver.

Thanks a lot for the help... The support with this mailing list is fantastic!!!

Hi, Benoit.

Remove the PINI, LINR, and ESLO fields from CavVoltSet.  Add a calcout
record named CavMillivoltSet to convert to V and write the value
via its OUT field to CavVoltSet.  Set the PINI field to "YES" on
CavMillivoltSet.
