Then, let's set the **Reconnect delay to 15000ms** and leave the **Protocol settings** and **Timing** fields with default values. ![Fig%203%20-%20Example](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Fig%203%20-%20Example.png) **![Fig%204%20-%20Example](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Fig%204%20-%20Example.png)** - **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. ![Fig%205%20-%20Example](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Fig%205%20-%20Example.png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/image(199).png) - **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. ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/image(196).png) ![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/image(198).png) - **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). ![Fig%209%20-%20Example](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Fig%209%20-%20Example.png) - **Step 8:** The tags should be now available and displayed with good quality in the **Real-Time** display panel. ![Fig%2010%20-%20Example](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/Fig%2010%20-%20Example.png) [IEC 104 Client Full Product Details](https://n3uron.com/iiot-platform-modules/iec-104-client/)
