Abstract :
The use of Ethernet based solutions in automation applications raises the question of test tools. Free tools like Wireshark, formerly known as Ethereal, are available and offer decoding of real-time Ethernet like PROFINET IO. But is such a software based tool able to measure the required real-time constraints? What are the limits of such software based measurements? This report gives an overview of possible measurement setups and a choice of measured benchmarks.
