Introduction
This chapter describes how to configure a list of network devices (remote hosts) in the network to which the Web server
CPU module communicates.
Applications
When the Web server CPU module accesses and communicates with other network devices in the network, the remote
host device should be specified. The remote host list is required to use the following functions:
• PING Instructions
• ETXD/ERXD Instructions (User communication over Ethernet)
• Modbus TCP Client
Description of Functions
The remote host consists of an IP Address or a Host Name and a Port Number.
When a remote host is specified with an IP address, the Web server CPU module establishes connection with the remote
host that has the specified IP address and the corresponding port number, then communication is started.
When a remote host is specified with a host name, the Web server CPU module tries to obtain the IP address from the
specified host name using the DNS server. If the IP address is successfully obtained, the Web server CPU module
establishes connection with the remote host that has the specified IP address and the corresponding port number, then
communication is started.
For details about DNS server settings, see Network Settings in the Function Area Settings.
Programming WindLDR
1. Double-click on the Remote Host List in the Project Window.
