Experimental Physics and
Industrial Control System

At our infrastructure monitoring system we have the case that
some temperature values should trigger an alarm only if they
remain above/below a threshold (HIHI/LOLO) for longer than a
defined amount of time.

As we could not find support for this feature in the documentation,
we would be glad to receive a suggestion regarding a solution or
implementation we could go for.

The involved sensor devices are represented by "ai" records
with a home-made device implementation. We use EPICS release
3.14 on Linux.
