I can think of another idea to add: set field(PINI, “RUNNING”) instead of “YES”.

"RUNNING" refers to the record scanning threads of the local database.  It is not a statement about remote PVA/CA links.

You may be thinking of a recent (unreleased) change which ensures that CA links to local records will be connected by RUNNING.  Sadly the reality of an unreliable world (network, power, etc.) prevents such guarantees from being made for remote links ;)

I tried different tricks for example setting field(VAL, "0") and field(PINI, "YES"), but none of them was successful.

I should also note that setting PINI to YES will leave this record with a INVALID LINK alarm as the PVA link is unlikely to be connected by the time of the initial process scan.

Depending on your desired reconnect behavior, you may wish to investigate the "retry" link option.

retry. For an output link, and true (not default), then the most recent incomplete PUT will be re-tried when the target PV (re)connects.
