Sensor Objects
The ROA sensor objects contain the sensor data received by the SensorIO 
Service. For examples, see the following table.
Meteorological Objects
The ROA meteorological objects are based on the sensor data objects. 
Each meteorological object is created by the corresponding meteorological 
service. For examples, see the following table.
Alarm Objects
Each process creates its own alarm objects. These objects are transmitted 
to the Remote Object Events (ROAALARM) process, which creates the 
ROAALARM object. For examples, see the following table.
