Multiple-Object Commanding

With multiple-object commanding, you are not really commanding objects at all.

Instead, you are commanding one property type, Present Value for instance, for

more than one object of the same type.

If you select multiple objects of the same type, for example, Analog Output, the

icon next to the property name in the Operation or Extended Operation tab

indicates this with a triangular symbol in the lower right-hand corner. Clicking this

symbol expands the table row to show all of the selected objects of the same type

that share this property. You can then change (command) all Present Value

properties for the selected objects at the same time. You can command a

maximum of 250 objects.

In the following graphic, the system indicates that you have selected multiple

objects by displaying a triangular symbol in the lower right-hand corner of the

Present Value icon.

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.

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, such as fire alarm, fault, or technical excluded.

The following table shows propagation from two different viewpoints.
