That is the behavior you will get if you set the SCAN rate to Passive. That means the record only processes when you write to the VAL field via a database link with the PP attribute or via channel access.

Subject: Process 'bo' on write?
Is there a way for me to set a bo (or ao) record so that it only
processes when it's value is changed?
I've got a number of those records that I only need written to the PLC
when the value is changed.
