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.
