Start Edge OPC UA Server

The Edge OPC UA Server Configurator allows you to configure data source, security configuration, and create user for Edge OPC UA client to access Edge OPC UA server. When you deploy the connections and data points, the Edge OPC UA server is started. The Edge OPC UA clients can access this data through Edge OPC UA server.

Prerequisite

The Edge OPC UA Server Configurator must be running.

Procedure

To deploy the connections to the Edge OPC UA server using provider model, follow these steps:

Step 1: Configure data source connection under "Data Source" tab.

1. Add a data source as described in Add Data Source section.
2. Connect the data source using .

Step 2: Select tags under "Data Points" tab.

1. Mark true against the check boxes of the connections and tags that you want to deploy as required. By default, all are marked true.

Note For User defined model, step 2 is optional.

Step 3: Select security policy under "Security" tab.

1. Mark true against the check box of the security policy as required.

The available options are as follows:

• "None": It specifies no security. When you select the 'None' security policy, any Edge OPC UA client can still connect using this setting, regardless of any security settings that follow.
• "Sign-Basic256Sha256": It specifies secure communication with signed client and server certificates.
• "Sign&Encrypt-Basic256Sha256": It specifies secure communication with signed client and server certificates with additional security where the data is encrypted from server application and sent to the client.

You must ensure that your selected security policy matches the algorithm that was used to generate the certificates.

For User defined models, you can configure "Models and "Nodes". For more information on configuring Models and Nodes refer User interface for OPC UA Configurator.

Step 4: Upload certificate and key under "Security" tab.

1. Upload the certificate and key using "Certificate" and "Key" field.

   This is an optional step. You may choose to upload the custom certificates or select "Generate self signed certificate" to generate self-signed certificates.

   Note
   Password protected privatekey.pem file is not supported.

   In case of user defined models: - The "Model" tab allows you to upload customized models using Unified Modeller/SIOME. -The "Nodes" tab allows you to map user defined models (consisting of data points, structure,variables), which adheres to the OPC UA Model with the existing data points available in the Edge OPC UA server.

Step 5: Create a user under "User Management" tab.

1. Create a user as described in Add Edge OPC UA Server User (Page 26) section.

   Note
   Alternatively, you can mark true against "Enable guest access" check box to enable anonymous login. The default or recommended login procedure is by creating a user and using the user credentials. You must use the anonymous login at your own risk.
   

Step 6: Deploy Connections and tags.

1. Click "Deploy".

   The connections and tags are deployed, and the Edge OPC UA server is started.

   Note
   - When the Edge OPC UA server disconnects from the Databus, it tries to connect to it for a certain duration. If the connection is not restored within this duration, a message is displayed on the UI that the maximum retry limit has reached. The next attempt to connect to the Databus is made only after the deployment of the Data Sources.
   - While using the Edge OPC UA Server Configurator application, you must configure your client to validate the status code of the respective node. If the status code is set to ‘bad’, the value of the respective node should not be referenced.
