    PROFIsafe is a protocol for safe communication, and is certified in accordance with IEC 61784-3-3. For the WAGO-I/O-SYSTEM 750, I/O modules were developed with safety- related inputs and outputs (F I/O modules) without any drastic changes to the existing series 750 system, making mixed operation of safety-related and non- safety-related I/O modules possible.

    WAGO-I/O-SYSTEM 750 Appendix 147 753-668/000-004 4FAI 0/4-20 mA Diff PROFIsafe Data is exchanged between the safe F I/O modules and the safe PLC via PROFIBUS or PROFINET as the basis. Data is exchanged in the form of PROFIsafe telegrams that correspond to the PROFIsafe protocol profile according to IEC 61784-3-3.

    Individual Parameters (iParameters) The individual parameters are used to configure device functions of a safe device such as the F I/O modules of the WAGO-I/O-SYSTEM 750. The “WAGO Safety Editor 75x” parameterization tool (SEDI) can be used to set the individual parameters of WAGO F I/O modules.
