Subject: How to tag soft channels as undefined/disconnected

Hi All,

We have set up an EPICS R3.14.12.4 database of pure software channels (on a Linux system) so that we can use the alarm handler. The channel values are being driven by a C++ software application that reads our instrument data. When the instrument data is stale (determined by an out-of-date timestamp), I would like to
set the channels to UDF so that the alarm state is INVALID.

The SEVR and STAT alarm fields are non-modifiable. I tried setting the UDF field but it didn't give me a disconnected channel.

Do I need to modify the record processing?

Suggestions?

Thanks
