However, when I try the same thing with a record that is tied to
hardware (also RTYP=ai but DTYP=asynFloat64, SCAN=I/O Intr) the record
doesn't process on writes to the SVAL field. Poking it manually ("caput
foo.PROC 1") triggers processing, though.
Is this how it should be? If so can someone shine some light on why it
is behaving like this?
This is how simulation mode was broken from the very beginning until recently (EPICS 7). ;-)
As 'I/O Intr' scanned records get scanned when the Device Support triggers them, and simulation mode - by definition - means that there is no Device Support, you have to configure the field SSCN (Simulation Scan) to have 'I/O Intr' records scanned using another mechanism in simulation mode.
See also 'Simulation Mode Improvements' in the Release Notes (will also be in the App Developers for EPICS 7).
