Assembly Object (04h)

Object Description
The Assembly object uses static assemblies and holds the process data sent/received by the host application. It
allows data to and from each object to be sent or received over a single connection.
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.
