Useful efficiency in cyclic transactions of Profinet IO
Piotr Gaj, Błażej Kwiecień · 2013
In this article the subject matter of using Ethernet network in industrial computer systems is considered. In this kind of systems it is required that the access to medium is determined in time and the time of network transaction execution should be finite and specified in range. There are numerous attempts of adaptation and standardization of various network technologies which fulfill such a kind of requirements for these type of applications. One of the most interesting is Profinet IO. Disclosure of useful efficiency value for key transactions such as cyclic ones is important to objective comparison of time features of fieldbus protocols, also those based on Ethernet.
