Ethernet Configuration

This section describes the system configuration of Ethernet.
Direct connection to an engineering tool
Engineering tool can be directly connected only with a single Ethernet cable, without using a hub.
In direct connection, communications can be performed simply by the transfer setup, without setting IP address.
Direct connection can cause an unauthorized connection from a remote location as an Ethernet cable is longer than an USB
cable.
Unauthorized connection can be prevented by setting "Disable" in the following item.

Use in a redundant system
The Ethernet-equipped module can be used in a redundant system.
Using the redundant system function enables the module to track a system switching and to issue a system switching request
to the CPU module when a communication error occurs.
For details on the redundant system function, refer to the following.
