N2 Service Objects
The Metasys N2 master protocol uses service objects to describe what services
the gateway should perform. For each service object, the gateway will continually
read the value of the defined N2 object within the service object from the
designated device, storing the value(s) in the database (if the read function is
enabled). When data in the database changes where the N2 objects are mapped,
a write request is generated to the designated device notifying it of the changed
value(s) of the N2 object(s) (if the write function is enabled). For more information
on configuring N2 service objects, refer to section 8.8.9.2.
