7.After entering the correct values, click the Set Button followed by the Reg- ist Button to register them.

The Set Button is used to transfer the entered values from the personal com- puter, 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 memory (non-volatile memory) of the CPU Unit. The Ethernet Unit reads the unit settings from flash memory (non-volatile memory) when the power is turned ON or the Unit is restarted. Therefore, when making the unit settings 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.

The functions of the other buttons are as follows:

•Cancel Button

Use this button to cancel the entered value and display the value that was previously set with the Set Button again. If the Set Button has not been clicked, the value that was read from the CPU Unit’s flash memory (non- volatile memory) when the Ethernet Unit was started will be displayed.

•Reload Button

Use this button read and display the values saved in the CPU Unit’s flash memory (non-volatile memory).

8.To enable the unit settings that have been registered in the CPU Unit’s flash memory (non-volatile memory, turn the power to the PLC system OFF and ON again, or restart the Ethernet Unit.

2-9 Basic Settings

The following items comprise the basic settings in the Ethernet Unit (100Base-TX) setup. Each item is described in detail below.

•IP address

•Subnet mask

•Broadcast settings

•Baud rate

•TCP/IP keep-alive

•IP router table

■IP Address

For the IP address, set the Ethernet Unit's local IP address.

Depending on the value that is set, the IP address has a great influence on the connectability of the Ethernet Unit. To make full use of the Ethernet func- tions, it is necessary to study the applications and network system design when determining IP address allocations. Before setting the IP address, refer to SECTION 5 Determining IP Addresses.

There are several ways to set IP addresses.
