5.11.2.3 Integrating a frequency inverter in PROFINET
Assignment of the RJ45 connector to integrate a frequency inverter into PROFINET
The CU240S PN and CU240S PN-F Control Units are equipped with an Ethernet switch for
two connections in the form of RJ45 sockets. Connections with optical networks are
established via switches, which are equipped with an electrical and optical port. The drive is
then connected to an electrical port, which means that no power supply is available for an
external electrical/optical converter.
