Assembly Object (04h)

Category
Extended
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 default assembly
instance IDs used are in the vendor specific range.
It is possible for the application to create and support up to six consuming and six producing instances if the
Assembly Mapping Object is implemented.
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.
