Configure the redundancy message channel

For the redundant pair of AppEngines to successfully communicate with each other, you must define the correct order of network connections in the network services of each computer.

We recommend that you name each card with a clearly identifiable function (for example, "Supervisory Net" and "Redundant Message Channel").

You must configure at least the following parameters:

• Redundancy Message Channel IP Address

• Redundancy Message Channel Port

• Primary Message Channel

To configure network cards

1. Open the Network Connections dialog box in Windows. The specifics about opening this dialog box varies, depending on the version of Windows you are working on.

2. Select Advanced Settings. If the computer name is used in the platform's "node name" box, the first connection in the list must be the supervisory network card. Use the up and down arrows to define the correct order.

3. Connections.

   If a computer contains more than two network cards, the supervisory net must be listed first and the RMC connection can be listed in any other position. For example, your computer might have a supervisory connection, a field device connection, and a RMC connection.

4. Configure the DNS settings for the supervisory network card to function properly.

   1. On the DNS page of the Advanced TCP/IP Settings dialog box, select the Register this connection’s addresses in DNS check box.

   2. For the RMC network card to function properly, clear the Register this connection's addresses in DNS check box. For more details on these settings, see Multiple network interface cards.

5. In Application Server, open the WinPlatform in the Object Editor for the computer you just configured.

6. Change the Redundancy Message Channel IP Address to the IP address of the RMC connection. See the WinPlatform Help for more information about these parameters.

7. Save and close.
