Hi everybody!
I'm a 3rd year engineering student.We are doing a project in which we are using microcontroller 89c51. We have one master controller & 3 slaves.We are using RS485 for interfacing.
Our professor has told us to use modbus protocol.We went through several articles on modbus protocol on web as well as books; but we are not getting how to implement it in the project.Is there any hardware available,or only the programming is required?
Please give your guidance.Waiting for your kind reply,
amavag
