Modbus Protocol - RTU/ASCII sample C/C++ code


Thread Starter

Kelly Moni

I am looking for sample modbus RTU or ASCII code either in C or C++. I am new to Modbus protocol, I did read the documentation about modbus protocol from the website.

Would like to get some sample source code to get me started with my application. Thanks in advance for the help!

I see no one (reply) sample of code for you to implement modbus.

I made a card with a microchip pic, and wrote the code to communicate in Modbus, and believe me; try, and you will see that it is not difficult to implement. I think the ascii mode is easier to implement.

You are on the way.
