Modules with PROFINET interfaces may only be operated in LANs (Local Area Network)
where all nodes are equipped with SELV / PELV power supplies or protection systems of
equal quality.
A data transfer terminal (modem, for example) is required to access the WAN (Wide Area
Network) in order to ensure compliance with this safety standard.
The CPU (including bus module) and the connection module CM CPU 2PN M12, 7/8" are
mounted on the module rack.
