### External Device Settings

Use the ladder software (Sysmac Studio) to configure communication settings for the External Device.

Refer to your External Device manual for details.

1. Start up the ladder software.

2. Click the [Configuration] of the [Multiviewer Explorer].

3. Double click [Controller Setup].

4. Double click [Built-in EtherNet/IP Port Setings] to display the setup screen.

5. Select [Fixed settings] from [IP Address] to set the IP address as follows.

   Setup Items | Setup Description
   --- | ---
   IP address | 192.168.0.1
   Subnet mask | 255.255.255.0

6. Transfer the communication settings to the External Device.

NOTE

- Check with a network administrator about IP address and subnet mask you want to use. Do not set the duplicate IP address.

NOTE

- Connection will be closed when an incommunicable state between the Display and the External Device continues and exceeds the time specified for Timeout for connection. Then, when the Display performs communication, the timeout error is displayed because the connection is closed. The timeout error is restored automatically.
  To prevent the timeout error from being displayed, make the settings so that communication may be performed in a shorter cycle than the specified timeout for connection, using a watchdog timer, and etc.
  The time for Timeout for connection can be calculated using the setting value of the communication settings. When "0" is specified for Retry, however, substitute "1" into the following equation.
  Time for Timeout for connection (s) =
  [Timeout] + ([Timeout] x [Retry]) + ([Wait To Send] x [Retry]) + 2
  Using the equation as shown above, time for Timeout for connection in the default ([Timeout]: 3s, [Retry]: 0 times, and [Wait To Send]: 0ms) should be 8s.
