You can do that with a Channel Access link.  The exact syntax depends on the record type, but something like the following:

record (ai, "MyLocalRecord") {
     field(INP, "MyRemoteRecord CP MS")
}

This will make the value of MyLocalRecord be fetched from MyRemoteRecord every time MyRemoteRecord posts a channel access monitor.

If you do not specify the type of your link, e.g.,

record (ao, "MyRecord") {
    field(OUT, "MyOtherRecord")
}

EPICS will determine the link type at boot time.

If the target record is found on the same host, that link will be a

database link, otherwise the IOC will try to resolve it remotely (using

Channel Access).
