5\. After returning to the **Network/Devices** go to the **Product catalog** menu on the right side of the window. Choose the *Other communication parties -> Modbus TCP -> WAGO -> Generic\_Modbus\_Master*. You can either double-click or drag-n-drop it to an empty field in **Network/Devices**. 

Click the grey bottom Ethernet output point of one block and then click a corresponding one at the bottom of the other one to create the connection.

Choose the **MODBUS (TCP)** Protocol option.
