Analog attribute runtime behavior: advisement of active items

If you configure the object to have input or input/output and advisement of active items is enabled globally, both the reference count and suspend count for the field attributes are incremented when the object starts up. This puts the object into a suspended state and propagates a suspend message to the input sources.

When the object is in a suspended state, no input scanning occurs, because no new input values are being sent by the input source. The quality of the suspended attribute is INITIALIZING.
