Advisement of active items

If you configure the object to have Read (input) or Read/Write (input/output) and advisement of active items is enabled globally, both the reference count and suspend count for the 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.
