Not using standard record types, and I wouldn't really recommend that you try to create a custom record type to do that because the database layer wasn't designed with that ability in mind â if you did manage to implement something like that, it could very easily break when a new release of Base comes along. The IOC was designed so that in most circumstances requesting or even monitoring data from any field is a "safe" activity that should not significantly affect the continued operation of the control system. If someone could cause the control system's behavior to change just by getting a value through channel access, engineers would be *much* more careful when diagnosing an IOC with which they have little familiarity. If you tell us what you're trying to achieve at a higher level, you might get some alternative suggestions on how to achieve that without needing to implement "process on get" semantics. - Andrew -- When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. -- Arthur C. Clarke
