UTP cable (7 foot) for Ethernet connection

1 GE-EGD (ETHERNET GLOBAL DATA) DESCRIPTION

The GE-EGD (Ethernet Global Data) driver allows the FieldServer to transfer data to and from devices over Ethernet
using GE-EGD (Ethernet Global Data) protocol. The FieldServer can emulate either a Server or Client.

GE Fanuc Automation and GE Drive Systems developed an Ethernet Global Data, or EGD, exchange for PLC and
computer data in 1998. EGD uses UDP or datagram messages for fast transfer of up to 1400 bytes of data from a
producer to one or more consumers. UDP messages have much less overhead than the streaming TCP connection
used for programming or CommReq’s over SRTP Ethernet. Like Genius® broadcast input or directed control
messages, UDP messages are not acknowledged. They can be sent at short intervals. Chances of one or more
messages being dropped are small on a local area network.

As a Client the FieldServer acts as an EGD consumer. As a Server the FieldServer acts as an EGD producer.

The IC697CMM742 Ethernet module supports both GE SRTP and GE EGD.

4 DATA ARRAY P AR AMETERS

Data Arrays are “protocol neutral” data buffers for storage of data to be passed between protocols. It is necessary
to declare the data format of each of the Data Arrays to facilitate correct storage of the relevant data.

5 CONFIGURING THE FIEL DSERVER AS A GE-EGD CLIENT

Historically, one uses the client-server model to describe the operation of most protocols. Recently producer­consumer model protocols have started to become more numerous. The GE-EGD (Ethernet Global Data) is a
producer-consumer model protocol. In equating the two models it is important to regard the consumer as a

passive (FieldServer) client. Other clients typically are active and poll for new data. The consumer is a passive
client in that waits to digest new data generated by a producer.

For a detailed discussion on FieldServer configuration, please refer to the instruction manual for the FieldServer.
The information that follows describes how to expand upon the factory defaults provided in t he configuration files
included with the FieldServer (See “.csv” files provided with the FieldServer).

This section documents and describes the parameters necessary for configuring the FieldServer to communicate
with a GE-EGD Producer.

The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable
the FieldServer for GE-EGD communications, the driver independent FieldServer buffers need to be declared in the

“Data Arrays” section, the destination device addresses need to be declared in the “Client Side Nodes” section, and
the data required from the servers needs to be mapped in the “Client Side Map Descriptors” section. Details on

how to do this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the default.
