# Examples

## Connecting to an IEC-102 Meter Through an Ethernet to Serial Converter Configured as a TCP Server:

In this example, **IEC 102 Client** is used to connect to a meter through a TCP connection. The configuration will include creating a gateway in order to permit the Utility to connect to the meter and download the load profile.

- **Step 1:** Create a module instance: (Config => Modules => button to the left of Modules => New module)

- **Step 2:** Provide a name for the module, in this case IEC102Client, set the module type to Iec102Client, and configure the new module as shown below.

- **Step 3:** Set the **API** and **Logger** configuration to default. Next, it's time to configure the module to establish which networks will be able to establish communication.
- **Step 4:** Create a new**Channel**and enter the **Host** and **TCP** port of your energy meter.![Figure 8 - 1.21.5](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Figure%208%20-%201.21.5.png)

- **Step 5:** Now, let's create and configure a **Gateway**for allowing and prioritizing the connection from the Utility as well as preventing collisions.

- **Step 6:** Once the **Gateway** is configured, let's add a new **Device**. Every **Device** requires both a **Link address** and a **Point address,** which can usually be obtained from the energy meter display.

- **Step 7:** Create and configure some tags to retrieve the data provided by the meter. Refer to this link for more detailed information on [creating tags](https://docs.n3uron.com/v122/docs/platform-creating-tags).

- **Step 8:**The tags should be now available and displayed with good quality in the **Real-Time** display panel.
