# Quickstart
In this 5–10 minute guide, you will set up communication with a Modbus TCP device and create several tags available for the OPC UA client. If you do not have Monokot Server, go to[ ](https://www.monokot.io/download/)[this](/basics/installation.md) section to download and install it.
### Connection to Monokot Server
1. Open Monokot Server Administrator
2. Create a new connection or just click the *Connect* button to connect to the local server
3. Please wait until the main application window opens
### Configuring Modbus TCP Device
1. In the *Server Explorer* pane, double-click on *Devices* to open the device manager
2. In the device manager, click on the *New Device* button
3. In the drop-down menu, select *Modbus TCP*
4. On the settings pane, enter the IP address of the target device and slave ID (if required)
### Creating Tags
1. In the *Server Explorer* pane, double-click on *Tags* to open the tags manager
2. In the tags manager, click on the *New Group* button
3. Double-click on the new group, name it as **MyModbusTags** and press the Enter key
4. Click on the *New Tag* button
5. To associate the tag with a device, double-click on the *Device* cell
6. Click on the *...* button in the device cell
7. In the device selector dialog window, select the **Device1** and click the *OK* button
8. Double-click on the *Address* cell
9. To specify Modbus register, in the address editor, type **300000\@WORD** and press the Enter key or use graphical address editor by clicking on the *Pen* button. Thus, the tag will be addressed to the first register of the Internal Registers area in the Word format
10. Click on the *New Tag* button and associate the created **Tag2** with **Device1**
11. Set address **400001.3** to **Tag2**. Thus, the tag will be addressed to the fourth bit of the second register from the Holding Registers area
12. To make your changes take effect, click on the *Sync* button (on the top panel) or press the F5 key
After the changes are synchronized with the server, the **Tag1** and **Tag2** will be associated with the specified registers and will become available to the OPC UA client.
### Testing by Third-party OPC UA client
In the OPC UA client, connect to the Monokot Server using the following endpoint parameters:
* Endpoint URL - **opc.tcp\://localhost:43043/MonokotOPC**
* Security Policy - **None**
* Authentication Mode - **Anonymous**
Now you can see the created tags and device in the object browser of your OPC UA client.
