You’ll be prompted to fill out key fields such as the node’s name, project, hostname, and UID. We’ll delve deeper into the process of creating nodes later. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/45.png) ### Node Table and Filters The table below these buttons displays information about all your nodes. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/46.png) Each column serves a specific purpose: - **Node Name:** This column lists the names of your nodes. You can use the text filter here to search for specific nodes or narrow down the list. - **Project Group:** This column organizes nodes by their associated project. Filtering by project name helps you focus on nodes related to a specific initiative. - **Host and UID:** These columns allow you to filter nodes by their host or UID values. - **Modules:**This column shows the number of modules assigned to each node. You can filter nodes based on the minimum or maximum number of modules they contain. - **Created:** This column displays the creation date of each node. Using the calendar filter, you can identify nodes created within a specific timeframe. ### Node Management Options To the right of each node in the table, you’ll notice two icons and a dropdown arrow: **1.** **Open Node:** Clicking this icon opens the node details page. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/47.png) Here, you can view comprehensive information about the node, including its configuration and associated modules. Additionally, this page provides several buttons for further actions: - **Edit:** Allows you to modify the node’s details. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/48.png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/48_2.png) - **Download License:** Lets you download the license file associated with the node ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/49(1).png) - **Edit License File:** Opens the license file for editing. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/50(1).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/50_2(1).png) - **History:** Displays a detailed history of the node, including who created it and any changes made over time. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/51(1).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/51_2(1).png) **2. History:** This icon directly opens a pop-up window with historical details about the node. It’s a quick way to review changes without navigating away from the main table. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/52(1).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/52_2(1).png) The dropdown arrow next to these icons provides a summary of the node’s key details in a compact view. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/53(1).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/54(1).png) ### Creating a Node and Assigning Licenses To create a node and assign licenses, start by clicking **Add New**. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/45.png) A pop-up will appear where you’ll need to fill out several fields: - **Name:**User-defined name that helps to easily and descriptively identify the node. You can choose any name that best suits your organizational needs. - **Project:**A project is used to group multiple nodes together. Project names can be chosen freely and may represent a geographic area, a portfolio, a production site, or any other grouping that fits your requirements. - **Hostname:**This is the hostname of the device where the license will be installed. You can find the hostname in the Licensing section of the node’s WebUI. - **UID**: This is the unique identifier of the node where the license will be installed. It can also be obtained from the Licensing section in the node’s WebUI. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/55(1).png) To avoid copy-paste errors, we recommend going to N3uron and using the **Copy to Clipboard** option. Once copied, paste it into the **Hostname**field, which will auto-fill both fields. Finally, click **Create**, and your node will be added. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/56(1).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/57(1).png) Once the node is created, expand it to find the **Create New License File** button. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/58(1).png) Clicking this will take you to the **License File Creator**. Here, click **+ Add New Module** to begin adding modules. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/59.png) A pop-up will appear with a dropdown menu labeled **Select the module**, listing all the available modules in N3uron. Choose the modules you wish to add to your node one by one. For example, let’s select **MQTT Client**. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/60.png) After selecting the module, a new window appears. Here, we can see the the **Remote Tags Access**. The **Remote Tags Access** property allows N3uron modules to access tags that are received from other N3uron nodes via [N3uron Links](https://docs.n3uron.com/v122/docs/platform-links). This functionality is essential when a module needs to interact with data that is not generated locally but instead comes from remote nodes within the N3uron network. > [!NOTE] > Note: > > Enabling Remote Tags Access requires **3** licenses per module. Remote licenses can only be assigned to specific modules, including**REST API Server**, **Data Exporter**, **Web Vision**, **Notifier**, **Audit Trail**, **Data Diode**, **Derived Tags**, **Scripting**, **Historian**, **Linked Tags**, and **UFL Exporter**. > > > > Example: > > Remote Tags Access is required for modules that handle or process tags from other nodes. Examples include: > > - **Historian:**To store tags centrally from multiple remote nodes. > - **WebVision:** To visualize tags from remote nodes in a centralized dashboard. In this case, we continue by clicking on **Add**to assign a local license and then we will explore a complete example explaining how to assign a module with Remote Tags Access. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/61.png) Another pop-up will display your available licenses; select one and click **Select**. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/62.png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/63.png) Repeat this process for additional modules as needed. For modules requiring remote licenses, the process is slightly different. Click **Add New Module**, select **REST API Server**, and notice the section in the pop-up labeled **Remote Tags Access**. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/64.png) If the module will use remote licenses (e.g., when a central node communicates with Links), click **Set as Remote**. The License Manager will then prompt you to select three licenses instead of one. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/65.png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/66.png) > [!NOTE] > Note: > > Remote licenses can only be assigned to specific modules, including **Server**, **Data Exporter**, **Web Vision**, **Notifier**, **Audit** **Trail**, **Data Diode**, **Derived Tags**, **Scripting**, **Historian**, **Linked Tags**, and **UFL Exporter**. Once all licenses are assigned to the node, click **Create**to finalize. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/67.png) The license file will automatically download, and your node will be ready to use. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/68(1).png)
