The Set Button is used to transfer the entered values from the personal computer, and temporarily register
them in the Ethernet Unit.
The Regist Button stores the set values that have been temporarily registered in the Ethernet to the flash mem-

volatile memory) when the power is turned ON or the Unit is restarted. Therefore, when making the unit set-
tings using the Web function, always click the Set Button before the Regist Button. Otherwise the entered set
values will not be used. The Set Button and Regist Button are provided on the window for each setting item.

deselect the Use Web Function option. Click the Set Button followed by the Regist Button. This setting
is enabled by turning ON the power to the Ethernet Unit again or restarting the Unit. This setting can be
cancelled only through the CX-Programmer Unit Setup (version 5.0 or higher).

• Cancel Button

ton again. If the Set Button has not been clicked, the value that was read from the CPU Unit's flash mem-
ory (non-volatile memory) when the Ethernet Unit was started will be displayed.
• Reload Button
