MODBUS–An Overview and Applications in Automation Supporting ASCII and RTU Mode Transmission

The Evolution Industrial Communication inexorably moves to Industrial Networks.Since the Modbus protocol was introduced in 1979, it has been adopted in manufacturing applications throughout the world. This paper gives an overview of all the aspects in which how MODBUS gives its contribution in this evolution of Industrial Automation. It also explains the various application of MODBUS which can be implemented using both ASCII and RTU transmission Mode.
