## Connecting to an IEC-104 Real-Time Automation Controller (RTAC)

In this example, the **IEC 104 Client** is used to connect to a Real-Time Automation Controller (RTAC).

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

- **Step 2:** Provide a name for the module, in this case, IEC104Client, set the module type to Iec104Client, and configure the new module as shown below.

- **Step 3:** Set the **Logger** configuration to default.
- **Step 4:** Create a new**Channel**and enter the **Host** and **TCP** port of your controller. Then, let's set the **R****econnect delay to 15000ms** and leave the **Protocol settings** and **Timing**fields with default values.

- **Step 5:** Once the Connection is configured, let's add a new **Device**. Then, enable the data collection and leave the **Common Address of ASDU** at the default value.

- **Step 6:** Once the Device is configured, let's add a new **Interrogation**. Then, let's choose the **General**group and leave the **Rate**at the default value.

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

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