### External Device Settings

Use the ladder software (STEP 7 Micro/Win32) for communication settings of the External Device. Please refer to the manual of the External Device for details.

1. Start up the ladder software.

2. From the [Tool] menu, select [Ethernet Wizard].

3. Click [Next].

4. Click [Read Module] to detect the installed Ethernet module.

5. Enter the [Position] value of the detected module in [Module Position], and then click [Next].

6. Set [IP Address] and [Subnet Mask], and then click [Next].

7. Enter "1" (the number of the Display to be connected) in "Number of connections to configure for this module.", and then click [Next].

8. Follow the steps below to set the Display, and then click [OK].

- Select "This is a Server Connection" to connect the External Device to the Display.

- In the "Local Properties (Server)" area, select "Accept all connection requests." to allow connections from all IP addresses.

- In the "Remote Properties (Client)" area, enter "10.00" in "TSAP".

- Clear the "Enable the Keep Alive function for this connection." check box because the Display does not support KeepAlive.

NOTE

- The connection number is displayed in this dialog box. If the connection number is "1", for example, [Connection 1] is displayed.

9. Click [Next].

10. To save the module configuration, set the memory address of the External Device, and then click [Next].

11. Click [Finish].

12. Click [Yes] for the confirmation message.

13. Select [Save] from [File], and download the configuration to the External Device.

NOTE

- Check with your network administrator about the IP address. Do not duplicate IP addresses.

- The subroutine "ETH0_CTRL" must be called by the ladder program every scan.

- When the Display is turned off and on again during communication with the External Device or is switched to offline mode and then back to online mode, it may take several tens of seconds before the communication is resumed.

NOTE

- Connection is lost when there is no communication between the Display and the External Device after 9 seconds. A time-out error is displayed as the connection is lost, when the Display tries to reconnect. The time-out error is restored automatically.
  To prevent the time-out error from being displayed, make the settings so that communication may be performed in a shorter cycle than the specified time-out for connection, using a watchdog timer, and etc.
- CP 243-1 IT and CP 243-1 can use the version of CPU above Rel.1.20.
