PV Values

PV values are set by the icpconfig code in two phases:

Static DB access

This attempts to run between autosave and PINI. This phase is only important for records with PINI=YES.

Note: internally, the static PV access library required you to specify the field - it will not default to .VAL for you. There is some code in icpconfig to do this.

Dynamic DB access

This attempts to run after the IOC is started. However, it works inconsistently for records with PINI=YES because you get a race condition between PINI running and the value being set.
