Abstract
This paper describes the realization of Modbus RTU master/salve protocol based on SIMATIC S7-300 PLC point-to-point communication module.In a practical packaging control system,data is transmitted reliably and effectively.The scheme is worth promoting economic significance,for avoiding the expense of Siemens driver module of Modbus protocol.
