Modbus is a widely used communication protocol in industrial automation and control systems. It allows devices to communicate with each other by exchanging data and control signals. Its integration into industrial systems has enabled greater control, flexibility and increased productivity. With Modbus, devices can communicate seamlessly with each other, regardless of the manufacturer. Modbus can operate on multiple physical layers, including Ethernet, RS-232, RS-485, and many more. Its simplicity and versatility make it a popular choice for industrial communication. Recently we completed a project in which an Atmega processor was integrated with Modbus and a bridge between Modbus and a custom communication protocol was implemented.

The Atmega processor was programmed to communicate using both the custom protocol and Modbus. The bridge was implemented using a software layer that translated messages between the two protocols. The final product was an application running on the Atmega processor that could communicate with both Modbus and custom protocol devices, allowing for data forwarding over the entire system.

The integration of Modbus into the Atmega processor proved to be a valuable addition to the system. By enabling communication with a wider range of devices, the system became more flexible and capable of performing a wider range of tasks. The successful completion of this project demonstrates the capabilities of a Norik team.
