 The main role of the Portenta Machine Control server is to operate a binary counter, programmed using digital outputs determined by a sub-counter variable, `cnt`. This variable operates within an 8-Bit value range. The counter's speed is modulated through `counter_buffer` and `delay_buffer`, using as adjustable timing parameters. For the client Portenta Machine Control, the shared Modbus counter variable known as `counter_stack` is used.

 To integrate the `counter_buffer` and `delay_buffer` variables, access the `New Variable` option by right-clicking on `Global_vars`. While `counter_buffer` can be designated as an `automatic` variable, `delay_buffer` was originally defined as a `constant` variable with a set value.

 To begin communication with the configured Modbus TCP Server Portenta Machine Control, you can add a Modbus node. Right-click on the 'Ethernet' section within the 'Resources' panel. It will reveal the 'Add' button. Click on it to introduce a 'Generic Modbus' node. For this example, we can set the node using these specific parameters:

+Now that you have learned to implement the Modbus TCP between Portenta Machine Control devices using Arduino PLC IDE, try expanding the setup by integrating additional Modbus TCP compatible devices into the communication network. You can enhance this setup further with Opta™. Learn more about it by watching this [video](https://youtu.be/reBrbCq86uQ).
 
 Additionally, you can explore the possibilities by leveraging the onboard features of the Portenta Machine Control device combined with the Modbus TCP communication network. This combination offers a robust enhancement solution for industrial management systems.
