That's relatively easy if you follow the processing chain in the
database. Removing the fields not related to that, every 10 seconds this
record gets triggered by the SCAN setting:

When that processing is finished, the FLNK field processes this:

Because that OUT link is marked PP, after writing the value it causes
this record to process:

Both of those links are also marked PP, so they will both process this
record, but with at least a 2 second gap (DLY3) in between:

The gap can be more than 2 seconds depending on how long the it took to
process the asyn record the first time (after setting CNT to 0).
