GE RX3i

Chapter 1. Introduction
4 PACSystems* RX7i & RX3i TCP/IP Ethernet Communications User Manual GFK-2224Q
▪ Network switch that has Auto negotiate, Sense, Speed, and crossover detection.
▪ Direct connection to BaseT (twisted pair) network switch, hub, or repeater without an external
transceiver.
▪ Protocol is stored in flash memory in the Ethernet interface and is easily upgraded through the CPU
serial port.
▪ Communications with remote PLCs and other nodes reachable through routers. The gateway IP
address must be configured.
▪ Internet access via web pages served up to standard web browsers, for the Ethernet interface
embedded in the PACSystems RX7i CPU.
RX3i Embedded Ethernet Interface - Features
▪ Full RX3i controller programming and configuration services with inactivity timeout
▪ TCP/IP communication services using SRTP.
▪ SRTP Client (Channels)
▪ Modbus TCP Server, supporting Modbus Conformance classes 0, 1, and 2.
▪ Modbus TCP Client, supporting Modbus Conformance classes 0, 1, and Function Codes 15, 22, 23, and
24 for Conformance class 2.
▪ Communications with remote PLCs and other nodes reachable through routers. The gateway IP
address must be configured.
▪ Comprehensive station management and diagnostic tools. For supported commands, refer to the
Station Manager Manual, GFK-2225J or later.
CPE305/310
▪ Extended controller connectivity via IEEE 802.3 CSMA/CD 10Mbps and 100Mbps Ethernet LAN port
connectors.
▪ Network switch that has Auto negotiate, Sense, Speed, and crossover detection.
▪ Direct connection to BaseT (twisted pair) network switch, hub, or repeater without an external
transceiver.
CPE330/CPE400
• Two independent 10/100/1000 Ethernet LANs. Port 1 attaches to LAN1 through a dedicated RJ45
connector. Port 2 attaches to LAN2 through a pair of internally-switched RJ45 connectors. Space is
provided to mark in the two corresponding IP addresses.
• The embedded Ethernet interface permits the CPU to support two LANs.
Note: CPE330 supports SRTP Client and Modbus TCP Client beginning with Release 8.50. The
CPE330 supports EGD Class 1 beginning with Release 8.60.
