PROFINET Netload Robustness Guideline (former Security Level 1 Netload)



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


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

The Guideline PROFINET IO Security Level 1  (Netload) is included in the PROFINET Test Bundle.

Le nostre tecnologie

PROFIBUS è un sistema di comunicazione digitale standardizzato ed aperto, utilizzabile in tutte le aree di applicazione, dal manifatturiero al processo.

PROFINET è l'innovativo standard aperto per l'Industrial Ethernet. E' in grado di soddisfare tutti i requisiti necessari per le applicazioni di automazione industriale.

IO-LINK è la prima tecnologia IO standardizzata a livello mondiale (IEC 61131-9) per comunicare con sensori ed attuatori sotto il livello di comunicazione del bus di campo. Può essere integrata con PROFIBUS e PROFINET.
