Configuring EGD
This section describes how to configure EGD using the Ethernet Global Data rack operation in the
Windows
-based PLC programming software (if supported).
The main topics covered are:
Exchange Definitions
Configuring Ethernet Global Data (with examples)
Exchange Definitions
The produced and consumed data exchange definitions that follow describe the fields to be filled
in via the Ethernet Global Data rack operation in the PLC programming software.
Produced Data Exchange Definition
The information to be sent by the producer and the exchange details are defined in the Produced
Exchanges tab of the Ethernet Global Data dialog box.
The produced data exchange definition contains the following information:
Field
Details
Local Producer ID
A value in the form of a dotted-decimal IP address that uniquely
identifies the Ethernet Global Data device across the network. For Series
90-70 PLCs, the default is the same as the IP address of the Ethernet
Interface closest to the CPU in the main rack. For Series 90-30 PLCs,
the default is the same as the IP address of the CPU364 or CPU374 with
Embedded Ethernet Interface. The default value can be changed.
Exchange ID
A numerical value assigned by the user to identify a specific exchange to
be sent by the producing device.
Adapter Name
Identifies the adapter name of the Ethernet Interface within the producing
PLC. For the CPU374 this field is not editable and displays the rack and
slot of the CPU.
Consumer Type
Specifies whether the data’s destination will be identified by an alias (if
aliases have been assigned), IP address, symbolic name, or Group ID.
Consumer Address
Identifies the data’s consuming device, based on the type selected:
Alias: a name assigned in the Alias tab of the Name Resolution dialog
box and selected from the drop-down list for this field.
IP Address: a dotted-decimal IP address.
Broadcast Address: Selecting this option causes the produced data to
be sent to the subnet broadcast address.
Name: an ASCII string of up to 31 characters. This name must be a
name that the Ethernet Interface will resolve into the needed IP address
using available name resolution protocols.
Group ID: the group’s ID number (1–32) selected from the drop-down
list for this field.
Send Type
Describes under what conditions data will be produced. Currently fixed
at “always”. In the PLC production of EGD is controlled by the I/O
state: when enabled, EGD production is enabled, and when disabled,
EGD production is disabled.
