Title: PC-Based Data Acquisition system Using Modbus protocol Over Serial communication interface
Author: Abdeen, Mohammed
Abstract: The objective of this project was to build an inexpensive, accurate and acceptable-speed data acquisition and control system, based on computer and serial interface. The project has made a great use of the features of computer (large memory, processing speed and graphical user interface (GUI)) and of the stand alone logger (reliability and not susceptible noise). A simulation was used to simulate the communication between master and slave devices using two computers. Then a real-time process have been develop by using computer holding visual basic program represent master and a stand-alone logger device (A 210 Multifunctional Power Monitor) represent slave. The serial interface used was RS-232 and the protocol was Modbus. The project was able to achieve the specified goals. Recommendations were made for further increase in speeds as well as network scale.
Description: The main objective of this project is to design and implement PC-based data acquisition systems and to facilitate design, specification, installation, configuration, and programming of data acquisition systems quickly and effectively.
