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:

ƒExchange Definitions

ƒConfiguring 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.
