I think you can just do:
record(ai, "pressure_in_torr")
{
field(DTYP, "Soft Channel")
field(INP, "loek_current CP MS")
}
CP means process this record whenever a channel access monitor is received on the INP link PV.

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.
