PROFIsafe

The PROFIsafe protocol can be used for safety-related applications up to SIL3 according to IEC 61508/IEC 62061 or PL "e" / category 4 according to ISO 13849. PROFIsafe is defined in the IEC 61784‑3‑3 standard. PROFIsafe is independent of the communication method and provides cost-effective and flexible functional safety. It covers the entire communication path from the sensor over the controller to the actuator and integrates safety and standard communication on one cable (black channel principle).
