Naming Conventions

If you follow consistent naming conventions for your Ethernet Global Data system, it will be much easier to configure EGD. These naming conventions include the following items:

ƒEquipment Folder Name – This is the name of the program folder that you assign when creating a hardware configuration and program for a PLC. It can represent the name of a PLC.

ƒProducer ID – This identifies the EGD producer and is configured in the Ethernet Global Data dialog box.

ƒAdapter Name – The adapter name is configured in the Module Parameters dialog box for the Ethernet Interface. This name is also referenced in the Ethernet Global Data dialog box of the PLC programming software. Note that for the CPU374 this field is not editable and displays the rack and slot of the CPU.

ƒAlias – Configured in the Name Resolution and Routing Table Rack Operation in the PLC programming software if you have decided to use local name table name resolution to connect to consumers.

ƒCCU Device Name – This is the name used by the Communication Configuration Utility (CCU), which is part of the Windows-based PLC programming software and Host Communication Toolkit, to identify an Ethernet Interface within a PLC to which you want to connect. When you configure these names, use a name similar to the adapter name of the Ethernet Interface.

When you assign names for these parameters, use names that help to easily recognize their relationship to one another.

For example, if you identify the PLCs in your system using an Equipment folder name such as PLC1, PLC2, and so on, it will be easier to recognize these PLCs when configuring EGD if you configure Local Producer IDs with numbers such as 0.0.0.1, 0.0.0.2, and so on.

Also, it is recommended to use a similar name for both the adapter name and the Communication Configuration Utility (CCU) device name for an Ethernet Interface. This will make it easier for you to recognize the PLC you want to connect to for configuring EGD. If you configure the CCU device name while an Equipment folder is open, the folder name will be suggested as the CCU device name.

Naming Conventions – EXAMPLE

Your Name	Local	Ethernet Interface(s)
for the PLC	Producer ID	Network	CCU Device	IP Address
(Equipment		Adapter Name	Name
Folder
Name)
PLC1	0.0.0.1	PLC1_A*	PLC1_A*	10.0.0.23
PLC1	0.0.0.1	PLC1_B*	PLC1_B*	10.0.0.34
PLC2	0.0.0.2	PLC2	PLC2	10.0.0.41
PLC3	0.0.0.3	PLC3	PLC3	10.0.0.50

* There can be more than one Ethernet Interface (Type 2) in a Series 90-70 PLC
