5.1 Product Specifications
The Ethernet Global Data (EGD) module can be used to interface many different
protocols with EGD devices. The EGD driver supports both the
producer/consumer service port (18246) and the command service port (7937)
using the UDP protocol over an IP network. The user defines the data to be
produced and consumed in a configuration file downloaded to the module.
GE Fanuc Automation and GE Drive Systems developed an Ethernet Global
Data, or EGD, exchange for PLC and computer data in 1998. Ethernet Global
Data (EGD) offers versatility where a mix of control devices requires cooperation
with each other. This involves sharing of information across the applications
regardless of device or network type, often at high speed, and with high
reliability. High reliability means fewer communication failures and having the
ability to detect failures upon occurrence. Particular emphasis is delivered for
applications requiring periodic or frequent updates and time synchronization of
devices. The protocol supports Unicast, Broadcast and Multicast group
messaging. Efficiency is based on the fact each device on the network can
produce these types of messages and each device determines which of these
messages to consume.
