Defining the Order of the NIC

For any multiple NIC ArchestrA node to communicate with all other Galaxy nodes, you must define the correct order of network connections in the network services of the computer.

Before you start configuring multiple network cards, you need the IP address for the second and subsequent nodes.

To define the correct order (Windows 8.1 and Windows Server 2012 and 2012 R2)

1. Open Network Connections through the Control Panel (access Network Connections through Control Panel > Network and Sharing Center, then select Change adapter settings).

2. Rename each network card with a clearly identifiable function, for example, Supervisory Net and PLC net.

3. Select Advanced from the menu bar (press the Alt key if the menu bar is not visible), and click Advanced Settings.

4. In the Advanced Settings dialog box, click the up and down arrows to define the correct order of Connections.

   • The first connection in the list must be the supervisory network card.

   • If a computer contains more than two network cards, for example, a supervisory connection, a PLC connection, and a Redundancy Message Channel (RMC) connection for ArchestrA redundancy, the supervisory network must be listed first. The others can be listed in any other position.

5. Click OK to accept the changes.

To define the correct order (Windows 10 and Windows Server 2016)
