SafetyNET p [1] is a communication protocol developed by Pilz GmbH & Co. KG, which allows the construction of industrial Ethernet-based networks and is suitable for both real-time communications and safety-oriented applications. The protocol enables the transmission of safety-related data on the same cable used for the transfer of control or process data. In fact, SafetyNET p makes available a logical safe channel that is certified in accordance with the safety integrity level 3 (SIL 3) of IEC 61508 [2] and can be used to transfer safety data without the need of a physical dedicated communication line.
