Configuring Ethernet Global Data

For more information about Ethernet Global Data, see Chapter 5
Ethernet Global Data can be configured in two ways. The most convenient way is to use the Ethernet Global
Data server that is provided with the PLC programming software. This server holds the EGD configurations for
all the devices in the EGD network. When the Configuration Server is used, the EGD configuration for the entire
EGD network can be validated for accuracy before the configuration is stored into the devices of the network.
This can greatly decrease the time needed to commission a network or implement changes in a network.
EGD exchanges can also be configured without using the server. Both methods are described in this chapter.
The choice of whether to use the Configuration Server can be made individually for each device.
Note: Some items in this discussion do not apply to Ethernet network interface units when using
ENIU templates. For configuration of EGD with ENIUs, refer to the PACSystems RX3i
Ethernet NIU Manual, GFK-2439.
Basic EGD Configuration
Whether or not the EGD Configuration Server is used, certain
steps will need to be taken to use EGD. These steps are
described below.
If Ethernet Global Data does not appear as shown, right-click
the PLC icon (PLC1 in this example). Select 'Add
Component' and then select 'Ethernet Global Data'.
For each PLC:
1.
In the PLC programming software, open the Project
folder and expand the target node for the PLC.
2.
To configure the Local Producer ID, right-click the
Ethernet Global Data node and choose Properties. The
Local Producer ID is shown in the properties Inspector
window. This parameter must be unique on the network.
The Local Producer ID is a 32-bit value that uniquely
identifies this Ethernet Global Data device across the
network. It can either be expressed as a dotted-decimal value
in the same way an IP address value is specified or specified
as an integer. It is recommended that this value be set to the
address of the Ethernet Interface with the lowest rack/slot
location in the system. The same Producer ID applies to all
exchanges produced by this CPU, regardless of which
Ethernet Interface is used to send the exchange to the
network.
While the form of the Producer ID is sometimes the same as that of an IP address and an IP address is used as
its default value, the Producer ID is not an IP address. See Chapter 5, "Ethernet Global Data," for more
information on how the Producer ID is used.
EGD Configuration for Redundancy Systems
For exchanges that are produced in backup mode, an offset must be added to the Exchange ID. This ensures
that the Exchange ID is unique for those exchanges that are produced simultaneously by the active and
backup controllers.
