GFK-2224Q January 2017 69Chapter 5 Ethernet Global DataThis chapter describes basic Ethernet Global Data (EGD) features, which are supported on all RX7i Ethernetinterfaces and by the rack-based RX3i Ethernet interface (ETM001). Effective with RX3i CPE310/CPE305Firmware Release 8.30, the RX3i CPU itself also supports EGD Class 13 on Embedded Ethernet Interface. RX3iCPE330 Firmware Release 8.60 supports EGD Class 1. All versions of CPE400 support EGD Class 1. The topicscovered are:▪ Ethernet Global Data Operation▪ EGD Exchanges▪ The Content of an EGD Exchange- The Data Ranges (Variables) in an EGD Exchange- Valid Memory Types for Ethernet Global Data- Planning Exchanges- Using Ethernet Global Data in a Redundancy System▪ Sending an Ethernet Global Data Exchange to Multiple Consumers- Multicasting Ethernet Global Data- Broadcasting Ethernet Global DataNote: For Broadcast addressing a Subnet value of 0.0.0.0 is NOT supported.▪ Ethernet Global Data Timing- Configurable Producer Period for an EGD Exchange- Consumer Update Timeout Period- EGD Synchronization▪ Time-stamping for Ethernet Global Data Exchanges▪ Effect of PLC Modes and Actions on EGD Operations▪ Run Mode Store (RMS) of EGD▪ Monitoring Ethernet Global Data Exchange Status
