B1.3.3.2 Constructing Multiple Field Wireless Networks
To construct multiple field wireless networks, perform the engineering task while keeping in mind
the following points.
-IP Address 192.168.0.101
-Subnet mask 255.255.255.0
-Default Gateway 192.168.0.1

Figure B1-12 Multiple Field Wireless Networks
l Network ID
When constructing multiple field wireless networks, network IDs must be designed so that they
are unique to each other on each of the networks.
l Setting network parameters for Ethernet connection
When constructing multiple field wireless networks, one YFGW710 must exist on each of the
networks.
When connecting each of the YFGW710s to the same Ethernet, IP addresses must be designed
so that they are not identical to each other. When the IP addresses are identical to each other,
communication cannot be performed normally not only with the YFGW710s with the duplicate
IP address, but also with all the YFGW710s, PCs, and control systems connected to the same
Ethernet.
l Project Database
Engineering information on multiple field wireless networks can be saved to a single project data-
base. Alternatively, a project database can be created for each of the field wireless networks.
This document recommends creating engineering information on multiple field wireless networks
in a single project database.
Field Wireless Configurator is designed so that duplicate network IDs cannot be created for the
same project to prevent duplicate network IDs. The use of a single project file for management
also facilitates the backup task.
