Hi Andrew,

I looked to see how PREC and other fields support DBE_PROPERTY in EPICS base.  I see that the ao, ai, etc. record dbd files put the attribute "prop(YES)" on fields that should generate DBE_PROPERTY callbacks.

I just added prop(YES) to the PREC field in motorRecord.dbd and now when PREC changes Phoebus updates the window to the new precision instantly, without needing to close and re-open the window.  This is great!

A couple of questions:
- If we were to add prop(YES) to fields in the motor record then it would require a minimum of base 3.14.11?

It would actually be >= 3.15.0.2

https://github.com/epics-base/epics-base/commit/3cccdd813458936b536f51589a100cfcfd91f637

My mistake.  This commit adds "prop(YES)" to the base .dbd files.
The C .dbd file parser has always ignored unknown recordtype "items".
(cf. dbRecordtypeFieldItem() ) so I think any 3.14 would ignore "prop(YES)".
