Assembly Instances
A so-called Assembly Object specifies the structure of objects for the data communica-
tion. The data (e.g.: I/O data) can be combined into blocks with the Assembly Object
Data and sent over only one communication link.
Thus less access to the network are necessary.
It is differentiated between Input Assemblies and Output Assemblies:
-Input Assembly reads application data over the net and/or produces data on the net-
work.
-Output Assembly writes data on the application and/or prozesses data of the network.
