GFK-2224Q January 2017 1Chapter 1 IntroductionThis chapter includes basic information about Ethernet Interfaces for the PACSystems family of controllers. Itdescribes features of the Ethernet Interfaces in both conventional and redundancy systems. The rest of thismanual provides instructions for installing and applying the PACSystems Ethernet Interfaces:Chapter 2, Installation and Startup: RX3i Embedded Interfaces describes user features and basic installationprocedures.Chapter 3, Installation and Startup: Rack-based and RX7i Embedded Interfaces describes user features andbasic installation procedures.Chapter 4, Configuration describes assigning a temporary IP address and configuring the Ethernet interfaceparameters. For the rack-based and RX7i embedded interfaces, describes how to configure Ethernet GlobalData (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 readand 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 communicationsover 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 thePACSystems family of products.Chapter 9, Modbus TCP Client explains how to program communications over the Ethernet network usingModbus TCP Channel commands.Chapter 10, OPC UA Server, explains how to program communications for this protocol using the embeddedEthernet port.Chapter 11, RX7i PLC Monitoring Via the Web describes the Web browser feature provided by a PACSystemsRX7i CPU with Embedded Ethernet.Chapter 12, Diagnostics describes diagnostic techniques for a PACSystems Ethernet Interface. This chapter alsolists COMMREQ Status codes.Chapter 13, Network Administration discusses how devices are identified on the network and how data isrouted among devices.Appendix A, Configuring Advanced User Parameters describes optional configuration of internal operatingparameters 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 oftwo programmer connections. It does not support the full set of features described in thismanual. 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 interfacefeatures, refer to Section 1.3.3.
