Basic System: One RX3i CPU and One PROFINET Controller using
multiple ports
The illustration below shows a basic system with one PACSystems RX3i CPU node that has one
RX3i PROFINET Controller module controlling one PROFINET network. The network can connect
up to 64 compatible IO-Devices, including any combination of VersaMax PROFINET Scanners and
third-party IO-Devices.
This example shows one RX3i PROFINET Controller that is directly connected to four separate
IO-Devices in a Star topology. Although each IO-Device is connected to a separate Ethernet port on
the PNC, they are all on the same network segment (IO LAN 1). The IO-Devices in this example are
all VersaMax PROFINET Scanners, but third-party IO-Devices can also be used.
