Connector

To configure the connector to the Ignition OPC UA server, from the Project Explorer select Connect, Connectors.

Under the Server tab, for Host Name, select or enter the name or IP address of the machine where the server is running. For Port specify the Bind Port as configured in the Ignition OPC UA Settings. This is typically either 4096 or 62541.

For Servers at Host click Find and then choose Ignition OPC UA Server.

If no servers populate or this times out, append /discovery to the end of the Port number and click Find again. After selecting Ignition OPC UA Server, remove /discovery from the port number field.

For User Identity click Select to specify.

For Ignition this can be either Anonymous or User Name. Anonymous can be used if the Anonymous Access Allowed setting is enabled in the Ignition OPC UA Settings.

Security Profile defines the endpoint to connect to for the Ignition OPC UA Server. Select the profile that matches the Security Policies set in the Ignition OPC UA Settings. To use a specific endpoint, select Specific and click the Select button.

Click Get Endpoints to get the list of available endpoints, select the one that best fits with the server settings and click OK.

Click Connect to ensure connectivity. This may require an exchange of certificates between the client and the server. If prompted to exchange, click Yes. This action requires Windows administrator rights.

If the Connect fails, be sure that the client certificate is trusted by the server and then attempt to Connect again. For more information, see the Trusted Clients section below.

The Disable server certificate checks option can be used to bypass all the checks normally done against the certifcate passed back from the OPC UA server. This is typically used if settings like the Domain or Application URI do not match what is expected but you would like to proceed with connection. Use this setting with caution as it disables many security features.

Under the Connection tab are Certificate options and general Settings.

The Client Certificate is automatically created on installation. If required, to recreate the certificate select Create Client Certificate. For most OPC UA servers, the default settings will be sufficient, but if the server requires more advanced certificate settings you can specify them with the Advanced button.
