Modbus TCP/IP Server does not show sensors and actuators

I have created a demo scene to start-top conveyer using start and stop button. Using the control io my logic is working just fine and my scene is running.
When I use Modbus TCP/IP Server option, the sensors and actuators are not detected as shown in below image.
Can anyone help me in solving this? What I am doing wrong?

Hello @seyowov893, welcome to the forum!

You have to map the tags by dragging and dropping each one, from the side columns, onto the intended port.

I hope this helps. If there is anything else you need help with, feel free to ask.
