gateway 192.168.0.24.
Set the IP addresses to values that do not conflict: Touch A IP address 192.168.0.1, Touch B IP address
192.168.0.2, computer IP address 192.168.0.3.

Local network
• Set the IP address, subnet mask, and default gateway according to the local network environment being
used. When Automatically obtain the IP address is selected, the network settings are automatically
assigned from the DHCP server on the local network environment being used.
• Settings assigned from the DHCP server can be checked on the Top Page in the System Mode.
•When Automatically obtain the IP address is selected, it make take some time to acquire the
network settings. If the download fails, increase the timeout time on the Home tab, in the Project
group, in Comm.Setup. For details, refer to Chapter 23 “1.3 Change Communication Settings” on page
23-5.
Protocol: N/A or External Device Communication. Varies based on the
Communication Driver selected for Protocol.
Automatically obtain the IP address (DHCP).: Automatically sets the network when connected to a network.
Use the following IP address: Manually specifies the IP address, subnet mask, and default gateway.
IP Address: Specifies the IP address. (Default: 0.0.0.0)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
When connecting multiple devices to the same
network, make sure to assign each device a unique IP
address.
Subnet Mask: Specifies the subnet mask. (Default: 0.0.0.0)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
This value must be the same for all devices.
Default Gateway: Specifies the default gateway. (Default: 0.0.0.0)
The format is “xxx.xxx.xxx.xxx”. “xxx” stands for a
numeric value from 0 to 255.
Set this value when using a router. Leave the value

Forbid Maintenance Communication: Select this check box to prohibit maintenance communication via
Ethernet communication.
About Networking Terminology
IP Address: The number allocated to identify devices connected to an IP network such
as the Internet or an intranet. The IP address is the address of each
individual device on a network.
Subnet Mask: The subnet mask is used to indicate the position of the division between the
network address portion and the host address portion of an IP address.
Default Gateway: The device such as a computer or a router that represents the gateway used
when accessing devices outside the network to which the device belongs.
