Hello,

I have an asynchronous device support, which sometimes acts
synchronously, if the access to an I/O card is possible without delay.
If not, a callback is used for the record completion.
In the database a record is running scanned periodically having an
INLINK with PP set. It gets data from a bi-record wich has the mentioned
device support. It seems to me that sometimes the data is not "new".
Does the scanned record complete before the asynchronous IO of the bi
record arrives?
If that is true - is the only possibility to solve the problem setting
the bi record into "scan" and use a FLNK to the previously scanned record?
Epics R 3.14.11
