Subject: About "dbCaMonitorLink" ?

Dear All;

I have a question on dbCaLink.

Suppose an IOC has a PV like this:

record(ai, "pressure_in_torr")
{
    field(DTYP, "Soft Channel")
    field(INP, "loek_current")

      ...

}

and another IOC has the referred PV something like this:

record(ai, "leak_current")
{
    field(SCAN, ".1 second")
    field(DTYP, "SOME_DEVICS")
    field(INP, "@some:address")

     ...

}

In this situation, the referring PV, "pressure_in_torr",
also needs to be scanned periodically to get the value
from "leak_current" through dbCaGetLink.

I'm wondering if I could use monitor function of CA to
transfer the data between the two IOCs so as not to cause
unnecessary traffic on the network. As far as I know,
there is no function something like "dbCaMonitorLink".

Is there any way to realize what I want to do?
I appreciate any comments and suggestions.

Thanks a lot in advance.
