Network Configuration Principle Using Control Expert
At a Glance
With Control Expert, the installation of a network takes place from the application browser and from the hardware configuration editor.
The method involves the following four steps:
creation of a logic network, configuration of the logic network, declaration of the module or of the PCMCIA card (for Premium), association of the card or of the module with the logic network.
These four methods are presented further on in this documentation.
NOTE: The advantage of this method is that from the second step onwards, you can design your communication application (you do not need the hardware to start working) and use the simulator for functional testing of it.
NOTE: The first two steps are carried out in the project browser and the following two in the hardware configuration editor.
This manual introduces the method. For details of the various network configurations, please refer to the following documentation:
Ethernet configuration for Premium (see Premium and Atrium Using EcoStruxure™ Control
Expert, Ethernet Network Modules, User Manual) , Ethernet configuration for M340
(see Modicon M340 for Ethernet, Communications Modules and Processors, User Manual) , and Ethernet configuration for Modicon M580,
Modbus Plus configuration (see Premium and Atrium Using EcoStruxure™ Control Expert,
Modbus Plus Network, User Manual) ,
Fipway configuration (see Premium and Atrium using EcoStruxure™ Control Expert, Fipway
Network, User Manual) .

Creating a Logic Network
At a Glance
The first step in implementing a communication network is to create a logic network.
Creating a Logic Network
The following table describes how to create a network using the project browser.
Step
1
Action
Expand the
Result::
Communication directory in the project browser.
2 Right-click in the
Result::
Networks sub-directory and select the New network option.

Action
Select the network that you want to create from the list of available networks and give it a meaningful name.
Result: Example of an Ethernet network:

Note: You can also add a comment, if you so desire, by clicking on the
Comment tab.
Click OK and a new logic network is created.
Result: We have just created the Ethernet network that appears in the project browser
Note: As you can see, a small icon indicates that the logic network is not associated with any PLC hardware. Furthermore, the small blue "v" sign indicates that the project needs to be rebuilt before it can be used in the PLC.

Configuring a Logic Network
At a Glance
The second step in implementing a communication network is to configure a logic network.
This manual introduces the access to network configuration. For information on how to configure the various networks, please refer to the following documentation:
Ethernet configuration for Premium (see Premium and Atrium Using EcoStruxure™ Control
Expert, Ethernet Network Modules, User Manual) , Ethernet configuration for M340
(see Modicon M340 for Ethernet, Communications Modules and Processors, User Manual) , and Ethernet configuration for Modicon M580 (see Modicon M580, Hardware, Reference
Manual) ,
Modbus Plus configuration (see Premium and Atrium Using EcoStruxure™ Control Expert,
Modbus Plus Network, User Manual) ,
Fipway configuration (see Premium and Atrium using EcoStruxure™ Control Expert, Fipway
Network, User Manual) .
Configuring a Logic Network
The table below describes how to access the configuration of a network from the project browser.
Step
1
Action
In the project browser, expand the directory tree under the Networks sub-tab located in the Communication tab of the tree directory to display all the project networks.
Example::

2 Double-click the network you want to configure to obtain the network configuration window.
Note: The windows differ according to the network family selected. However, for all networks, from this window it is possible to configure the Global Data, IPO scanning, Peer Cop utilities, common words, etc.
Note: For Ethernet networks, an intermediate step is necessary, which involves selecting the family of the module that will be used in the hardware configuration.

Associating a Logic Network with Network Hardware
At a Glance
The final step in implementing a communication network is to associate a logic network with a network module, Modbus Plus card or Fipway card. Although the screens differ, the procedure is the same for each network device.
How to Associate a Logic Network
The following table describes how to associate a logic network to a network device declared in the hardware configuration editor.
Step
1
2
3
Action
Open the hardware configuration editor.
Right-click the device (Ethernet module, Fipway PCMCIA card or Modbus Plus
PCMCIA card) that you wish to associate with a logical network.
Select the channel and function.
Result: For a TSX ETY 4103 module:

Network Configuration
Action
In the Network link field, select the network to be associated with the card.
Result:
5 Confirm your choice and close the window.
Result: The logic network is associated with the device. The icon associated with this logic network changes and indicates the existence of a link with a PLC.
Furthermore, the rack, module and channel numbers are updated in the logic network configuration screen. In our example we obtain the following project browser:
