You should be able to use the DISA and DISV fields to do what you want.  Here is an example:

record(longout, "$(P)$(R)FileNumber_write")
{
    field(SDIS, "$(P)$(R)FileNumber_Sync.PACT")
    field(DISV, "1")
    field(DTYP, "asynInt32")
    field(OUT, "@asyn($(PORT),$(ADDR),$(TIMEOUT))FILE_NUMBER")
}

So the SDIS field is a link to a field in another record.  Since DISV is 1 this means that this record will not process if $(P)$(R)FileNumber_Sync.PACT is 1.

Subject: Regarding database links


Hi,


Can anyone guide me on enabling and disabling of epics Records. I want to use one PV whose value should control the processing of a second PV.
I know that there are certain epics field like DISA,DISV which can can be used to control the record processing but I am unable to use these.
Also i don;t know how the commands of dbPutLink are executed. THough it is very basic can any one help me on this part.

Thanks
Himanshu
