The Emerson logo is a trademark and service 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: Section 2:, Installation and Start-up: RX3i/RSTi-EP Embedded Interface describes user features and basic installation procedures. Section 3:, Installation and Start-up: Ethernet Module Interfaces describes user features and basic installation procedures. Section 4:, Configuration describes assigning a temporary IP address and configuring the Ethernet interface parameters. For the RX3i rack-based and embedded interfaces, describes how to configure Ethernet Global Data (EGD) and set up the RS-232 port for Local Station Manager operation. Section 5:, Ethernet Global Data describes basic EGD operation for rack-based and embedded interfaces. Section 6:, Programming EGD Commands describes a set of commands that can be used in the application program to read and write PLC data or use Ethernet Global Data exchange data over the network. Section 7:, SNTP Operation describes the benefit of synchronizing SNTP-capable interfaces with an SNTP server to keep internal clocks up-to-date for accurate timestamp communications. Section 8:, 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 9, Modbus/TCP Server describes the implementation of the Modbus TCP Server feature for the PACSystems family of products. Chapter 10, Modbus/TCP Client explains how to program communications over the Ethernet network using Modbus TCP Channel commands. Chapter 11, OPC UA Server explains how to program communications for this protocol using the embedded Ethernet port. 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.
