| Abstract:In the automation and control, along with the development of distributed control systems, distributed control in industry System, using serial communication to achieve the purpose of remote information exchange easier. Developed RS485 Is to balance the electricaltransmission standards in the electrical indicators have increased significantly. Because of its performance, Results Structure is simple, easy networking, network cost, RS485 bus standard has been more widely used, Meanwhile, the bus RS485 Modbus protocol is used in open communication protocol, and is a lot of work Control products manufacturer support, the agreement has been widely used in water conservancy, electric power, metallurgy and other industries equipment and systems System of international standards. This article focuses on Schneider PLC using Modbus protocol converter with ABB Data communication. |
