Only use the device for its intended purpose. If unspecified devices are connected to the
RF18xC/RF18xCI, the connected device may be destroyed.
PROFINET IO connection system
You can find detailed information on connecting the RF18xC/RF18xCI on PROFINET IO in
the "SIMATIC PROFINET system description
(https://support.industry.siemens.com/cs/ww/en/view/19292127)".
Power supply for devices with PROFINET interfaces
Modules with PROFINET interfaces may only be operated in LANs (Local Area Networks)
in which all connected devices are equipped with SELV/PELV power supplies (or have
equivalent protection).
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.
All supply and signal voltages must be safety extra low voltage (SELV/PELV according to
IEC 61140).
