Change of State I/O Messaging
The Powermonitor II supports Change of State (COS) I/O Messaging
which reports data on a change-of-state basis as the events happen,
rather than a master going through a polling list.
Change of state messaging is typically more efficient for discrete
applications; for network traffic is significantly reduced, and
performance is greatly improved.
