Title : Development of Modbus based Digital I/O Card with RS-485 Port for Industrial Applications Abstract: This is Electronics project report on development of Modbus based digital I/O card with RS-485 port for industrial applications. Development of MODBUS based digital I/O cards are very easy to deploy the network and it is royalty free for distribution and it is widely used in industries and industrial application. MODBUS is a serial communication protocol published by Modicon in 1979 for the use with its programmable logic controllers (PLC’s). An embedded system is a special-purpose system in which the computer is completely encapsulated by the device it controls. A data logger is an embedded system device.In addition to commonly described embedded systems based on small computers, new classes of miniature wireless devices called motes are quickly gaining popularity as the field of wireless sensor networking rises. Wireless sensor networking ,WSN, makes use of miniaturization made possible by advanced IC design to couple full wireless subsystems to sophisticated sensor, enabling people and companies to measure a myriad of things in the physical world and act on this information through IT monitoring and control systems. These motes are completely self contained, and will typically run off a battery source for many years before the batteries need to be changed or charged. An Embedded System is a combination of Hardware and Software that may have some mechanical components to perform specific tasks.
In this Project Report study, The data logger is very useful in broad range of applications. We chose a data logger system among many themes for graduation thesis. The report contains the block diagram, circuit diagram, and full microcontroller programming.
