The following graphic shows that you have clicked the triangular icon. The system
now displays two additional rows, which represent two selected objects of the
same type.
3.4.1.5 Propagation
Propagation means relaying Common Status information up the building control
system's hierarchical tree. Information that is relayed up the hierarchy as a result of
a change in the Common Status of an object is called status propagation.
Propagation is based on the parent-child-grandchild model. Each object in the
system can have one or more parent objects and one or more child objects. Each
child in the system can simultaneously propagate multiple active Common Status
properties to a parent —for example, fire alarm, fault, or technical excluded.
The following table shows propagation from two different viewpoints.
