PROFINET Netload Robustness for Security Guideline (former Security Level 1 Netload)



PROFINET Security Level 1 has been renamed to PROFINET Netload Robustness for Security!


Because Security becomes more and more important for production networks, robustness and an adequate behavior in case of security incidents are necessary qualities of automation devices. The netload test helps to improve these qualities.

In order to achieve a common approach to evaluate the behavior of PROFINET IO nodes a netload test is used to provide common test conditions.

The Guideline "PROFINET Netload Robustness for Security" (7.302) describes the focus of the netload test and provides background information concerning the netload test as part of the PROFINET certification.

The document "Testspecification PROFINET Security Level 1 (2.302)" has been integrated into the PROFINET test specification! It does not exist as an individual document anymore!

The Guideline PROFINET Netload Robustness for Security is included in the PROFINET Test Bundle.
