With the nowadays rapidly increasing complexity
and distribution of automation and control systems the
communication has an increasing impact on the control and
measurement tasks. There are several approaches to ensure realtime
communication in distributed systems. However these are
typically based on complex hardware or middleware concepts.
This paper will show an approach for real time communication
in switched Ethernet networks for closed automation systems
without the need for complex concepts. As basis for this approach
will serve the fact that at closed systems the whole communication
is described within the application. Furthermore, this paper
shows a way to improve the communication efficiency by collating
messages and analyses the communication delay for switched
Ethernet in different network setups.
