information on the online capabilities of the EMT. Also see the EMT help for information about running the EMT.
Configuring EGD Devices Not Supported by the EGD Configuration Server
Some devices, for example, certain Ethernet NIUs cannot be configured using the EGD configuration server.
Configuration tools for third-party devices that support Ethernet Global Data may not support the EGD
configuration server. Rather than not using the server in applications that contain these devices, there is an
alternative that allows the EGD configuration for such devices to be put into the server so that it can be used
for consumption and validation in other devices.
The programmer distribution includes a tool called the EGD Generic Device Editor. This tool allows you to
describe the EGD configuration of a device and publish it to the EGD configuration server. Configuration tools
for other devices can use the EGD configuration published by the EGD Generic Device Editor for consumption or
validation purposes.
Installing the EGD Generic Device Editor
The EGD Generic Device Editor is not automatically installed when you install the Programmer. To install the
GDE, look in the directory where you installed the programmer and you will find a subdirectory named “EGD
Installs”. In that directory, you will find a file named “EgdGenericEditorSetup.msi”. Double-click on this file to
install the EGD Generic Device Editor.
Running the EGD Generic Device Editor
Installing the EGD Generic Device Editor adds it to the Start – Programs menu of the computer’s Windows
system. You will find it under Programs - GE Industrial Systems-EGD Generic Editor. The Windows help for this
tool describes its operation.
Configuring Ethernet Global Data without Using the EGD Configuration Server
If the EGD Configuration Server is not used, each Ethernet Global Data exchange must be configured in both
the producer and the consumer. To add exchanges, expand the Ethernet Global Data node in the Project tab.
Right click the Consumed Exchanges or the Produced Exchanges node and choose New. The new exchange
appears under the selected list node.
1.
For each Consumed and Produced Exchange, configure the parameters described here.
2. To specify the variable ranges for each exchange, right click the exchange and choose Configure Ranges.
The EGD Variable Range Editor window opens.
Configuring an Ethernet Global Data Exchange for a Producer
The information to be sent by the producer and the exchange details are defined in the Properties for each
Produced exchange (also called a “page”).
When an individual produced exchange is selected, the Properties inspector window permits user configuration
of the following information:
Name
A name assigned for this exchange. Defaults to “ProdExchX” where X is a sequential
number.
Exchange ID
A number that identifies a specific exchange to be sent by the producing device.
Adapter
Name
The specific Ethernet Interface, identified by its rack and slot location within the producing
PLC.
Destination
Type
Specifies whether the data’s destination will be:

An IP address (Unicast)

A Group ID (Multicast)

All EGD nodes on the subnet (Broadcast IP).
