save in another PV the last sample (scalar) (or more samples) of other PV that is updated periodically.

this is for example: i have the temperature of a room being updated periodically. I want another PV to act as a buffer that stores the last two samples of the room's temperature . And i want to be able to acess them individually of course.

Thanks!

Please clarify a bit further.

What do you mean by "save"?
Write to a file? Store in an archiver? Write to another record?
What kind of PV?
Scalar or array data?
If array: does "last" mean last array in time, or last element in array?

Cheers,
