Installation guidelines for modules with PROFINET
IO interfaces
Ensure that all devices are connected to the SELV/PELV power supply (or equivalent). Only
then are you permitted t
o operate the modules with PROFINET IO interfaces in LAN networks
(Local Area Networks).
A data transfer point that guarantees this degree of safety is prescribed for connection to the
WAN (Wide Area Network).
