Hi Bob,

Dalesio, Leo wrote:
DESY would like to see the following changes:

SMOO applies to all values returned from device support - weather or not they need to be converted. This should have no impact - as device support that returns engineering numbers likely does not have SMOO set to anything. Same thing for returning values from database links that are inputs. Any objections?


I think that would break device supports that emulate the SMOO behavior when returning numbers in engineering units. I have written a few of them.

Add the following fields
TOUT - timeout before raising an INVALID/TIMEOUT alarm when the record has not been processed (esp. in Passive or I/O Intr scanning mode).
