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.

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.
