I HAVE NUCLEO-F207ZG BOARD AND I WANT TO CONTROL ITS I/Os ON MODBUS TCP IP PROTOCOL. AND I ALSO WANT TO PUBLISH ANALOG DATA ON HOLDING REGISTERS ON MODBUS TCP IP. KINDLY HELP AND IF THERE ARE ANY SAMPLE CODES THEN PLEASE DO SHARE IT WITH ME.

If you have any answer then say. Why do you have to say unnecessary things. if you have answer then reply otherwise not. you shared the link to search on google. Don't you think I would have done that.

>>Don't you think I would have done that.

I'd assume not, you've posted repetitively on the same topic about things YOU want to do, but given 100s of available projects, and perhaps 1000s within a short porting step, you fail to even find something to copy and work on yourself. I just don't think people here are going to dump a prepackage solution on your lap, MODBUS falls more into the commercial domain, and you might have to find engineers with specific competencies in it use and implementation.

Perhaps you have a colleague or boss who can help guide you to a solution, or you can find a commercial solution with code/support.

Tesla DeLorean,

I am an student and the reason I asked for a prepackage solution is so that I can study it and then implement it on other boards. Any given example so far has bugs and error. I am in my learning phase and if I were capable of solving bugs at this initial stage why would I even ask for help here. This is actually a matter of common sense which is not that common I guess. people like you are just thinking yourself superior but you are not my friend. I am a student and I need a project on modbus tcp ip which do not have any bugs so that I can study on it and understand how it works. If you can help then do it otherwise there is no shortage of people like you who just give unnecessary knowledge but not the proper solution.

Beginners must start at... beginning! And Modbus TCP implementation is definitely not for beginners. Have you learned the C language and compilers sot that you can create non-trivial projects with multiple files, use and create libraries? Have you learned data representation in memory? Can you implement FIFO, LIFO and linked list data structures easily? Have you written a decent UART driver? When you will learn these basic things, you will be able to find Modbus TCP related and similar answers on your own...
