Assembly Object – “Static”

Class Code: 04hex

The Assembly Object binds attributes of multiple objects,

which allows data to or from each object to be sent or

received over a single connection. Assembly objects can be

used to bind input data or output data. The terms “input”

and “output” are defined from the network’s point of view.

An input will produce data on the network and an output

will consume data from the network.

The term “Static” implies: assemblies with member lists

defined by the device profile or by the manufacturer of the

product. The Instance number, number of Members, and

member list are fixed.
