## OpenLM Broker configuration

*Diagram of OpenLM interface with Siemens SIMATIC*

Broker reads the Siemens SIMATIC log file. Once read, data is compiled and sent to OpenLM Server.

OpenLM Broker must be [installed](https://www.openlm.com/application-notes-v3-0/installing-openlm-v3-0/broker-comprehensive-installation-guide-an4004b/) and [configured](https://www.openlm.com/Knowledgebase%20and%20articles/openlm-broker-configuration/) to report to OpenLM Server before continuing:

1. Click **Add Port**.
2. Since Broker reads only the log file, enter any port number (for example, 888).
3. Select **Siemens SIMATIC** from the **License Manager Type** list. Click **Apply**.
4. Select **Vendor Name to Be Filled** under **Vendors**. Enter `Siemens SIMATIC` in **Vendor Name**. Click **Apply**.
5. Select **Log Files**, then click **Add Log File**.
6. Select the new **log** node. Click **[…]** and browse to the path of the Siemens SIMATIC License Manager `.log` file.
7. Click **Apply**.
8. Click **Restart Broker**.

### Alternative: Configuration through Broker Web UI

1. Open a browser and go to [http://localhost:5090/](http://localhost:5090/).
2. Click **License Managers**, then **Add License Manager**.

3. In the pop-up, select the license manager type, enter any port number (for example, 888), then click **Add**.

4. Go to **Vendors**. Click **Add Vendor**, enter the name, then click **Confirm**.

5. Go to **Log Files**.

6. Click **Add Log File**, then either enter the path manually or browse for it using the magnifying glass icon.
7. Select the log file, then click **Open**.
8. From the drop-down, select vendor `Siemens SIMATIC`.
9. Click **Continue**.

10. Click **Save**.

## OpenLM Server configuration

### Automatic configuration through EasyAdmin

If you followed the steps above, OpenLM Broker should now send data to OpenLM Server. Approve the configuration in EasyAdmin:

1. Open EasyAdmin (**Windows Start → OpenLM → OpenLM EasyAdmin User Interface**).
2. In **License Servers**, find the row for the new Siemens SIMATIC License Manager server (unapproved rows are highlighted red) and double-click it.

3. Give the connection a descriptive name or keep the default. Keep **Type** as **OpenLM Generic**. Click **Approve**.

Once added, data appears after parsing. A green circle confirms status.

### Manual configuration

If automatic configuration fails, manually connect OpenLM Server to the OpenLM Broker on the Siemens SIMATIC License Manager machine.

The hostname and port must match the Broker configuration.

1. Go to **Start → Administration → License Manager Servers**.
2. Click **Add LM**.
3. Select **OpenLM Generic** from **Type**.
4. Enter a description (for example, `Siemens SIMATIC`).
5. Set **Time Zone** to the license server location.
6. Enter **Hostname** and **Port**.
7. Clear **Is Triad Configuration**.
8. Select **Use Broker**.
9. Click **Save**.

## How to verify configuration

1. Open EasyAdmin in a browser.
2. Go to **Start → Widgets → License Servers**.
3. Verify Siemens SIMATIC appears in the list. A green circle indicates an active connection.

If new, the status indicator may take up to three minutes to update.
