Creating a Virtual Network

To set device parameters and to program the NE1A-SCPU01, create a virtual network in the Network Con-
figurator, set the device parameters in the virtual network, and then download them the parameters to the
actual devices.
This section describes how to create a virtual network.

Creating a New Virtual Network

When the Network Configurator is started, a new virtual network can be created.
Only one virtual network can be edited simultaneously. Use one of the following methods to create another
network.
(1) Select File - New from the menu bar.
(2) Click the New Button on the toolbar.
Note: When a new virtual network is created, the virtual network information that was displayed until then
will be deleted. If the previous virtual network information is required, save the data before creating a
new virtual network.

Network Numbers

The network number (i.e., the network address) is the number set for each network domain. All devices on
the same network must have the same network number.
The network number is set as a unique node identifier (UNID) in combination with the node address from the
Network Configurator and saved in the device. UNID is used to identify one device from all the network do-
mains.
The Network Configurator automatically creates the network number based on the time and date when a new
network configuration file is created. Under normal conditions, the user does not have to consider this oper-
ation.
Note: When the parameters are downloaded to the devices, the network number is transferred with the pa-
rameters as the UNID and saved in the devices. Therefore, when using a device whose parameters
have already been downloaded to another domain, set the reset type to Return to the out-of-box con-
figuration, and then emulate cycling power and perform a reset to clear the UNID.
Use the following procedure to set the network number.
(1) Select Network - Property from the menu bar.
(2) In the Network Number Field, select the Manual Option and enter the value.
IMPORTANT:

Always allocate a unique network number when a network or subnetwork is established.
