Experimental Physics and
Industrial Control System

We don't use reccaster in in the upgraded APS, but we have adopted the naming convention (from Python?) that record names which end in an underscore '_' are intended for internal use within the control system only, and shouldn't be used on any published display screens or by other clients. We haven't gone so far as to remove them from the lists of PV names that our name-servers recognize (which would limit access to other IOCs or clients running in the same subnet), but that would be our equivalent to what Daniel is asking for.

I would think it should be relatively easy to filter out matching names like that inside the reccaster code, whereas searching for an info tag in each record would probably slow up the reccaster somewhat at start-up. The use of a naming convention also makes it easier to see when someone is using a PV name that they aren't supposed to be connecting to.
