Two RX3i CPUs with Two PROFINET Networks and One Ethernet
Network
The example on this page shows two RX3i CPU nodes, each with one RX3i PROFINET Controller
module and one RX3i Ethernet Transmitter Module (ETM). The PROFINET Controller modules are
connected to separate networks (IO LAN1 and IO LAN 2 in the illustration). IO LAN1 and IO LAN2
are used for PROFINET IO traffic.
The RX3i Ethernet Transmitter Modules are connected to the same Ethernet LAN (LAN 3 in the
illustration). Proficy Machine Edition (PME), HMI, and Historian use LAN 3 to configure and monitor
the application. LAN 3 is also used for inter-node communication such as EGD, SRTP, and
Modbus/TCP. The three separate networks do not compete for network bandwidth or interfere with
one another.
