Chapter 1 Introduction
This chapter includes basic information about Ethernet Interfaces for the PACSystems family of controllers. It
describes features of the Ethernet Interfaces in both conventional and redundancy systems. The rest of this
manual provides instructions for installing and applying the PACSystems Ethernet Interfaces:
Chapter 2, Installation and Startup: RX3i Embedded Interfaces describes user features and basic installation
procedures.
Chapter 3, Installation and Startup: Rack-based and RX7i Embedded Interfaces describes user features and
basic installation procedures.
Chapter 4, Configuration describes assigning a temporary IP address and configuring the Ethernet interface
parameters. For the rack-based and RX7i embedded interfaces, describes how to configure Ethernet Global
Data (EGD) and set up the RS-232 port for Local Station Manager operation.
Chapter 5, Ethernet Global Data describes basic EGD operation for rack-based and RX7i embedded interfaces.
Chapter 6, EGD Commands describes a set of commands that can be used in the application program to read
and write PLC data or Ethernet Global Data exchange data over the network.
Chapter 7, Programming SRTP Channel Commands explains how to implement PLC to PLC communications
over the Ethernet network using Service Request Transfer Protocol (SRTP) Channel commands.
Chapter 8, Modbus TCP Server describes the implementation of the Modbus TCP Server feature for the
PACSystems family of products.
Chapter 9, Modbus TCP Client explains how to program communications over the Ethernet network using
Modbus TCP
Channel commands.
Chapter 10, OPC UA Server, explains how to program communications for this protocol using the embedded
Ethernet port.
Chapter 11, RX7i PLC Monitoring Via the Web describes the Web browser feature provided by a PACSystems
RX7i CPU with Embedded Ethernet.
Chapter 12, Diagnostics describes diagnostic techniques for a PACSystems Ethernet Interface. This chapter also
lists COMMREQ Status codes.
Chapter 13, Network Administration discusses how devices are identified on the network and how data is
routed among devices.
Appendix A, Configuring Advanced User Parameters describes optional configuration of internal operating
parameters used by the Ethernet interface. For most applications, the default Advanced User Parameters (AUPs)
should not be changed.
Note: The RX3i CPE305/CPE310/CPE400 embedded Ethernet interface provides a maximum of
two programmer connections. It does not support the full set of features described in this
manual. For a summary of RX3i CPE305/CPE310 embedded Ethernet interface features,
refer to Section 1.3.2. For a summary of RX3i CPE330/CPE400 embedded Ethernet interface
features, refer to Section 1.3.3.
