3.4 Assembly Object (Class ID: 0x04)
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 of ”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.
