Develop a NetLogic to configure network

Prerequisites
Set the default external code editor. See Set the default code editor.
  1. In the
    Project view
     pane, expand the
    UI
     folder.
  2. Right-click
    MainWindow (type)
     and select
    New
    Runtime NetLogic
    .
  3. Hover-over the NetLogic, select
    Edit
    , and enter
    NetworkConfigurationor
    .
  4. Double-click the NetLogic.
    The external code editor opens.
  5. In the code editor, paste the following code:
    #region Using directives
using UAManagedCore;
using FTOptix.Core;
using OpcUa = UAManagedCore.OpcUa;
using FTOptix.HMIProject;
using FTOptix.NetLogic;
using FTOptix.System;
#endregion

public class NetworkConfigurator : BaseNetLogic
{
    public override void Start()
    {
        // Insert code to be executed when the user-defined logic is started
        var model = Project.Current.Get("Model");
        systemNode = model.Get<FTOptix.System.System>("System1");

        if (systemNode == null)
            throw new CoreConfigurationException("SystemNode not found");
    }

    public override void Stop()
    {
        // Insert code to be executed when the user-defined logic is stopped
    }

                networkInterface.DNS2 = dns2;
            }
        }
    }

                networkInterface.DefaultGateway = defaultGateway;
            }
        }
    }

    public void AddAdditionalIp(string interfaceName, string ipAddress, string mask)
    {
        foreach (var networkInterface in systemNode.NetworkInterfaces)
        {

            {
                var additionalIPAddressVariable = InformationModel.MakeVariable<MaskedIPAddress>("MyAdditionalIP", OpcUa::DataTypes.String);
                additionalIPAddressVariable.SetValue(ipAddress);
                additionalIPAddressVariable.Mask = mask;
                networkInterface.AdditionalIPAddresses.Add(additionalIPAddressVariable);
            }
        }
    }

    private FTOptix.System.System systemNode;
}
  6. Save the code.
The following APIs are available: 
public PlaceholderChildNodeCollection<NetworkInterface> NetworkInterfaces { get; }
public IUAMethod RefreshMethod { get; }
public IUAMethod RebootMethod { get; }
public void Reboot();
public void Refresh();
NetworkInterfaces
 represents the list of all network interfaces. The structure of a network interface is as follows: 

public IUAVariable InterfaceNameVariable { get; }
public bool DhcpEnabled { get; set; }
public IUAVariable DhcpEnabledVariable { get; }
public string IPAddress { get; set; }
public MaskedIPAddress IPAddressVariable { get; }
public string DNS1 { get; set; }
public IUAVariable DNS1Variable { get; }
public string DNS2 { get; set; }
public IUAVariable DNS2Variable { get; }
public string DefaultGateway { get; set; }
public IUAVariable DefaultGatewayVariable { get; }
public PlaceholderChildNodeCollection<MaskedIPAddress> AdditionalIPAddresses { get; }
  • To enable DHCP, see Configure a dynamic network.
  • To disable DHCP, see Configure a static network.
  • To update the values stored in the System1 object (as a result of an external change), invoke the
    Refresh
     method
    systemNode.Refresh();
  • To restart the system, invoke the
    Restart
     method
    systemNode.Reboot();
