### External Device Settings (Connector for ethernet on EH-ETH2)

Use the setting tool (EH-ETH2 Configurator) for communication setting.

Note that the ladder software (Ladder Editor for Windows) is used for setting up the environment of the External Device.

Please refer to the manual of the EH-ETH2 for more details.

1. Assign the Ethernet unit to CPU unit by using [I/O assign] in the ladder software.

2. Turn ON the DIP Switch 1 and 6 of the Ethernet unit, and turn ON the power. Then, a temporary address (192.168.0.4) for accessing the Ethernet unit will be set.

Bit No.*1 | Operation Mode
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8
ON | OFF | OFF | OFF | OFF | ON | OFF | OFF | Communications Parameter Setting Mode

*1Use Bit No.4 to No.8 to set the fourth octet of IP address. The IP address is fixed to 192.168.0. until the third octet.

3. Connect the PC’s Ethernet port and the EH-ETH2’s Ethernet port by LAN cable. (Connect via HUB or connect directly using a cross cable.)

4. Start the setting tool.

5. Select [Communication Setting] from the [Option] menu.

6. Enter "192.168.0.4" in the IP address input box and click [OK].

IMPORTANT:

- To access, PC’s IP address up to the third octet must be set to 192.168.0. (192.168.0.10, etc.)

7. Click [Set Ethernet Parameters] to display the setting dialog box.

8. Click [Online] and read out the current setting values.

9. Set each item as follows:

- IP Address Set

  Setup Items | Setting
  --- | ---
  IP Address | 192.168.0.1
  Subnet mask | 255.255.255.0
  Transfer speed / Type | Auto Negotiation

- Task Code Logical Port No. Set (Port1)

  Setup Items | Setting
  --- | ---
  Port No. | 3004
  Protocol | TCP/IP

10. Click [Set] to display the setting complete dialog box and click [OK].

11. Turn OFF the power of the External Device. After turning OFF all DIP Switches, turn ON the power of the External Device.

NOTE

- Check with a network administrator about IP address. Set up unique IP addresses on the same network.
