PROFIsafe

PROFIsafe is a protocol for secure communication that is certified in accordance
with IEC 61784-3-3.
I/O modules equipped with safety-related inputs and outputs (so-called F I/O
modules) have been developed for the WAGO I/O System 750 without radical
changes to the existing 750 Series system. This allows mixed operation of safety-
related and non-safety-related I/O modules.
Figure 34: Mixed Operation of Safety-Related and Non-Safety-Related I/O Modules
A safe PLC (PROFIsafe and PROFINET host) with a PROFINET interface is
used as the controller.
Data is exchanged between the safe F I/O modules and the safe PLC via
PROFINET as the basis. Data is exchanged in the form of PROFIsafe telegrams
that correspond to the PROFIsafe protocol profile IEC 61784-3-3.
