Chapter 1. Introduction
1.6.7 Two RX3i CPUs with Two PROFINET Networks and One Ethernet
Network
Figure 12 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 LAN2 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 (LAN3 in the illustration).
Proficy Machine Edition (PME), HMI, and Historian use LAN3 to configure and monitor the application. LAN3 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.
