### Settings of External Device (LAN-ETH, LAN-ETH2)

Use the ladder software (Ladder Editor for Windows) to enter the value for appointed I/O No. for communication setting.

Please refer to the manual of the ladder software for more details.

1. Assign the Ethernet unit in the CPU unit.
Perform the environmental setting to allow the CPU unit to communicate with the ladder software.

2. Use [I/O assign] in the ladder software to assign the Ethernet unit to I/O.

3. Use [CPU Write] in the ladder software to write the I/O assignment setting in the External Device.
That completes the environmental setting of the External Device.
