# Examples

The following steps show how to access data coming from an OPC XML server using **N3uron's****OPC XML Client** module.

- **Step 1:** Create a module instance (Config => Modules => Model=> New module)

- **Step 2:** Provide a name for the module (in this case OpcXmlClient), assign the module type (in this case OpcXmlClient), and save the new configuration settings.

- **Step 3:** Configure the **Logger** and **API** sections (the default values are usually sufficient). Save these settings.

- **Step 4:** Create a new client (Config => Modules => OpcXmlClient => Model => New client).

- **Step 5:** Provide a name for the client (in this case OpcXmlClient01) and configure as appropriate. For this example. the following settings have been used:
  - **Connection**
    - **Host:**10.101.3.210****
    - **Port:**80****
  - **Authentication**
    - **Username:**user****
    - **Password:**n3uron

The rest of the parameters have been left as their default values.

- **Step 6:** Create a new tag (Config => Tags => Model=> New tag)

![Figure 12- Create a new tag(3)](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Figure%2012-%20Create%20a%20new%20tag(3).png)Figure 8. Create a new tag

- **Step 7:** Provide a name for the tag (in this case Tag) and configure it as appropriate. All details regarding communication should be configured in the Source entry.

- **Source:**
  - **Enabled:**Yes****
  - **Module Type:**OpcXmlClient****
  - **Module Name:** OpcXmlClient ****
  - **Config:**
    - **Client:**OpcXmlClient01****
    - **Address:**Random.Item1****
    - **Array:**No****
    - **Index:**0****
    - **OPC scan rate:**5000
